Herbert W. Olson Abstract 1 Statement 9; This study was completed for the purpose of t_h_e Problem comparing two groups of subjects: track athletes who won letters during the years 1886 to 1937 and non-athletes matched by years of attendance in college. The comparisons were made on longevity, morbidity and other closely related areas. Methods and, The track athletes' names were located in Procedures ~ the permanent records of letter winners at the athletic office of Michigan State University. The non- athletes' records were found in the files of the registrar. The last-known addresses of both groups were obtained from the alumni files. A letter and questionnaire were sent to each track athlete and non-athlete. To accelerate the number of returns, two follow-up letters at intervals of four and six weeks were also sent. There were 210 questionnaires returned by track athletes and 165 questionnaires returned by non-athletes. A coding system for entry of all information on I.B.M. cards was devised. The information from the questionnaires was punched into I.B.M. cards and was then analyzed using chi square and critical ratio tests. Literature 2E. The best studies completed in the area of [Engevity - longevity were those of Alan Rook1 (195A) and Louis Dublin2’3 (1928, and 1932). In Book's study a, ’- Herbert W. Olson 2 control group of non-athletes selected at random.were used. The mean ages of death were not significantly different when a comparison was made, but a group of intellectuals was found to live two years longer than either the sportsmen or non-sportsmen. Louis Dublin, a foremost authority on longevity, made two studies. One was completed in 1928 and the other in 1932. His first study used insurance statistics for his comp parisons and made his study less valid. His second study was more complete in that he used a control group of college non- athletes. Dublin found little difference between sportsmen and non-sportsmen, but the honor students were found to have a longer length of life. Other studies in the area of longev- ity used insurance statistics which did not give as valid com: parisons as a group of control subjects at random, Summary In the present study many statistically signifi- cant differences in the data were obtained. Track athletes were found to weigh.more during college. They also had.a greater percentage serve in the armed forces with a larger mean number of years in service. A greater proportion of track athletes drink alcohol than do non-athletes. Track athletes have more living brothers, and a greater number of deceased sisters. More of the non-athletes are of the Opinion 'that athletics are harmful.

The track athlete showed no significant difference in mean age of death. The number of accidental deaths occurred at an earlier age than those of the non-athletes. Track athletes seem to have come from larger families. The economic status of both groups improved slightly after college. Track athletes appear to use more tobacco when a comparison was made. It was observed that the mean age of death for parents and I grandparents of the non-athletes is slightly higher. References 1.

The American way of life emphasizes this idea, and has brought about a keener interest in all areas of athletics. The schools of our country are now including athletics in their programs to a far greater extent than they had previously. Grade schools are beginning to produce teams for inter-school competition in numerous sports. This development of athletic teams from the lower grades to the college level has cost a great deal of time and money. Many educators of today are not in agreement with the idea that this intensive develop- ment of athletic programs is worth the time and expense for, the returns that are forthcoming. Critics have indicated numerous times the great number of athletes who have died early in life, implying that athletics, and athletic training are the cause of these deaths. These accusations are in no way to be considered trivialities. All areas of sports must be thoroughly investigated to determine whether this line of I.‘ reasoning is of any merit. Statement The present study has been carried on for the 9; Problem purpose of procuring and comparing information on the Longevity, Morbidity and other closely related areas of a group of varsity track athletes, and a comparable age group of college non-athletes. The Track Athletes that were used are varsity letter winners from the years 1886 to 1937. The group of non-athletes were analogous in that they also attended Michigan State University in comparable years. These non-athletes were picked at random from the registrar's student directories. L“ Importance A study of Longevity and Morbidity of athletes g; the §tudy holds some importance in the future of athletics. People are beginning to wonder if there aren't too many harmful effects from sports and athletic training. Very little good research has been completed to produce evidence for either aspect of this question. Every authentic study completed in these areas may clarify many of these questions which have been forthcoming from the critics of athletics. The conclusions of this study may have some effect on training programs and future trends in sports. This study may well be another objective reached in an endeavor to dis- cover information for the purpose of making sound conclusions on the length of life of athletes as compared to non-athletes. Limitations The limitations of this study are as follows: 1. The questionnaire was made up by the Phi Epsilon Kappa fraternity's committee on Longevity, and in some instances the questions were ambiguous. 2. Many of the relatives of deceased athletes and non- athletes could not complete certain areas of the questionnaire because they lacked this information. 3. In the process of picking out non-athletes in a ran- dom.stratified sampling, some of these former students were from foreign countries or had moved to areas outside the con- tinental United States. These subjects were a little more lax in their replies to the questionnaire and to the follow-up letters. A. In the process of mailing questionnaires and follow- up letters there could have been a few letters that were not forwarded to subjects who had moved to new locations, thus limiting the number of responses. 5. This study could bring out some conclusions that may differ with other Universities' findings due to environmental conditions, different methods uSed in training and program planning. 6. The results of this thesis, as in most questionnaire studies, contained a certain number of bias answers due to the fact that all the responses are on a subjective basis. CHAPTER II REVIEW OF THE LITERATURE The length of life that the populace may expect to reach is of great interest to people in all walks of life. Particu- larly interesting are the expected longevity and morbidity figures of the athlete. Numerous opinions have been voiced on the subject with a great deal of feeling, seemingly, op- posed to athletics. This, however, is not accepted as true fact because there has been a number of studies completed which hail athletics as beneficial to the people who partici- pate. One of the first Studies of this nature was completed in 1893 by John E. Morgan.1 In Morgan's study, a comparison was made between the calculated longevity of oarsmen from.the years 1829 to 1859, and the English Life tables of those times. -The comparison appeared to be in favor of the oarsmen by a mean average of two more years of life. This was a step in the right direction, but due to the method of comparison, this study cannot be taken as positive proof of the superiority of the athlete in longevity. Morgan used a group of selected 1J. E. Morgan, "Critical Inquiry Into the After-Health of the Men Who Rowed in the Oxford and Cambridge Boat Race from.the Year 1829-1859," University Oars, p. 300, 1873, cited by P. V. Korpovich, "Longevity and Athletics,” Research Quar- terl , Vol. 12, (May l9hl), pp. h51-55. athletes and computed their longevity in groups of eight, presuming that this could be done with accuracy in such a small group. He then compared them to an English Life table based on the mortality of the general populace. This in it- self draws criticism, because a comparison of a selected group of athletes as against the longevity of the general popula- tion is not justifiable as a good comparison. Meylan's2 study of "Harvard University Oarsmen" was the next research project of this nature to be completed. In this study Meylan selected 152 oarsmen from the years 1852 to 1892 inclusive. The data were collected by a personal in- terview or with the help of the family physician. The infor- mation sought was the length of life and the causes of death of this group. The selected group of athletes had 123 of their number still living on November 1, 1902. In his com- parison of longevity, Meylan used the American Experience Tables of Mortality, and it seemed that a healthy young ath- lete of 20 years could expect to live h2.2 more years. Ac- cording to Meylan's tables, the oarsmen lived 2.88 years in excess of expected mortality table figures. If the normal expectation of life for those oarsmen that were killed by wars and accidents had been added to the figure of 2.88 an increase to a mean of 5.09 years for each athlete would have been recorded. 2George L. Meylan, "Harvard University Oarsmen," Harvard Graduates Magazine 9: 115-12h, March, l90h. In the causes of death of the deceased athletes of this study only 22 of the 32 were known. The list of these causes is as follows: six in Civil War; two in accidents; two with heart disease; three with pneumonia; two with apoplexy; one with paresis; one with cancer; one with consumption; two with Bright's disease; one of alcoholism, and one by a tropi- cal climate. Meylan did not believe that rowing was a Significant factor for any cause of death in his study. He further thought ' that rowing was a benefit to competing oarsmen. A study of the longevity of Yale athletes by William G. Anderson,3 a Director and Professor at the Yale Gymnasium, was completed in 1916. Dr. Anderson secured his information on a group of 880 Yale athletes from the files of the College Publication Obituary. Anderson presents his data in Table I on the number of deaths and their distribution among four sports during a fifty-year span from 1855 to 1905. Table I also presents a fairly clear picture of the ratio of expected deaths to actual deaths, and this information is based on the statistical tables of insurance companies from those same years. The author states, as shown by the table, that Yale letter winners do not die younger than the general population. He also 3William G.

The causes of death among athletes in this study were as follows: twelve had consumption; six had pneumonia; five had typhoid; two had typhoid pneumonia; four drowned; four had heart failure, and five were unknown. The other twenty deaths were each of a different cause. Anderson concludes that lung trouble and heart disease were the greatest causes of death, but the percentage from these causes was no greater for the athlete than for the non- athlete. Greenway and HiscockLL completed a study in 1926 on "Mortality Among Yale Men," and in their study, a group of 686 lettermen and a group of 9,h21 non-letter men were studied for their length of life and causes of death. The athletes that were picked as subjects had won their letters during the years 190h to 1923. This excluded any of the athletes that were used in the study by Anderson. The information on the deaths among both groups can be discerned in Table II. The mortalities that were caused by war injuries are 50 percent higher among the athletes than among the non- athlete subjects in this study. The authors further presented information that the athletes have one more man per thousand ”James C. Greenway, and Ira V. Hiscock, "Mortality Among Yale Men," Yale Alumni Weekly, 35: 1806-8, June, 1926.

This might lead people to believe that non-athletes from college live longer than athletes, but Greenway and Hiscock point out that this percentage of war deaths account for that figure. The evidence presented is in- terpreted by the authors as being attributable to the athletic type having a greater abundance of physical energy and natural courage which causes them to endanger themselves by undue risks. The limited number of subjects used in this study could not establish enough conclusive evidence to assure the validity of the information. It does Seem that in all these studies it might be fairly easy to conclude that college athletes and non- 10 athletes seem to live longer than the general populace in- volved in the insurance tables statistics. The study that was completed by Bradford Hill5 in 1927 on "Cricket and Its Relation to the Duration of Life" was an investigation of 3,h2h cricket players from.0xford, Cambridge and other English counties. The data was taken from the 1926 "Wisden's Cricketers Almanac" which devoted one whole section to biographical information on first class cricketers that were born between 1800 and 1888. Hill divided this group of athletes into two groups. The cricketers born between 1800- 18u9, and those born between 1850-1888. He then compared each of these groups with an English Life Table for those same years. The information on these comparisons is eluci- dated in Table III. The figures show a distinct advantage in favor of the cricketers all through the tables. This may not be quite correct because of certain errors that could be the fault of the almanac death records. Hill's study also compares in Table IV the amateur cricketers and professional cricketers. JThe figures in the table indicate that the amateur athlete shows a longer length of life, and according to the author, these amateurs could have had an easier life in a greater number of cases. There are a great number of causes that could affect “—7 A.

The group did their rowing between 1885 and 1905 for Ormand College. The number of deaths in this group was twenty-four, of which seventeen died of natural causes, and seven died of war injur- ies. The death of twenty-four athletes compared to 38.8 of the general male population designates a lower mortality rate for the oarsmen. The study by Knoll11 in 1938 was a counter-action against dubious claims made in medical works about longevity in cars- men without scientific basis. The results of this inquiry into the records of 880 oarsmen, who rowed in the Oxford- Cambridge races, were very enlightening. The average age of death of the participants was 56.1 years. This average would have been much higher had the cases of premature death been subtracted that were due to causes other than those that may have been influenced by athletic training. The 155 deaths in- cluded eight infectious diseases, seventeen tropical diseases, twelve accidents and forty—five war casualties, or over one- half of the total mortalities. There was no comparison with loEric L. Cooper, John O'Sgllivan, and E.

Another study on the oarsmen from Oxford and Cambridge was completed in 1939 by Hartley and Llewellyn.12 The informa- tion that was used in this study was gained through the Offi- cial Centenary History of the University Boatmen. The oarsmen that were studied had competed in 80 races between 1829 and 1928. There were A31 oarsmen who had died by the end of 1928, and this group was used in the statistics of the study. The data were compared to a table of expected deaths to give a better view of the results that were attained. In Table VIII, four sets of insurance tables were used which was an improvement from.the previous method because of the increased longevity through the years. The use of standard tables is not a fair comparison, but this method used by Harley and Llewellyn is better than using one mortality table for this range of ages. The authors men- tion that it would be better to use fellow graduates as a comparison of life expectancy. A study of the causes of death of 100 soccer players was completed in l9ul by C. J. Van Mervenne.13 This study 12Percival Herton-Smith Hartley, and Geoffrey F.

Heart disease and circulatory attacks seem.to'be the greatest cause of death among this group killing kl sotcer players out of the 100 men in the group. The information on all the causes of death of this group of soccer players is in Table IX. In 19Hh, a study of mortality was completed on basket- ball players from the state high school finals of Indiana.1h This research was done by Wakefield to perceive what compari- son there was between high school basketball players, and the mortality rate of the general population. The record of bas- ketball players that competed in the state tournaments from 1911 to 1935 were taken from files of Indiana High School Athletic Association. The age and cause of death omeost of these players were found in the State Board of Health re- cords, cemetery records and morticians records. The final number of subjects was 2,919 basketball players, and among this group, there were 123 actual deaths. The expected deaths as taken from.death rates of the general population was 181.1, which was 67.9 percent of actual deaths to expected deaths. Among the group that died, the causes of death were: external violence 3h.1 percent; cardiovascular-renal diseases 16.3 percent; tuberculosis of all types 13.8 percent; pneumonia 1""Mark C.

These percentages were favorable except for cardiovascular-renal and external causes. These were in favor of the general populace. The basketball player that played in one, two or three games in a day all seem to live longer than the expected death rate. The fourteen, fifteen and sixteen-year olds who played in the tournaments had a better life expectancy than the seventeen, eighteen and nineteen year olds; 5h.2 percent to 78.9 percent respectively. The general conclusion was in favor of the basketball players as compared to United States Life Tables. Schmid15 in 1952 published an article on the length of life of MOO former sportsmen from.Bohemia and Moravia who had at least ten years of sports competition. The athletes who were killed during the first and second world wars were omitted from the study. The ages reached by these athletes were: cyclists 6u.83 years; competitors in apparatus work 58.53 years; oarsmen 5h.66 years; swimmers 53.67 years; track and field athletes 52.50 years; football players 50.93 Years; tennis player 50.6u years, and heavy-weight athletes h6.8u years. The mean age of all the athletes was 5h.72 years, but when the number that died of external violence was subtracted, the mean age is 57.81 years. The author compares this group 13L.

Education, 1952), pp. 100-109. of athletes with a group of non-athletes from the population in the table below. TABLE I A COMPARISON OF NON-ATHLETES AND ATHLETES MEAN AGE OF DEATH (FROM SCHMID, 1952) Year of Non-Athlete Athlete Birth Mean Age Mean Age 1861.1870 58.2k 66.90 1871-1880 60.28 61.72 The author found that the influence of marriage proved interesting. The athletes had a ratio of 8:1 of married men to unmarried men. The mean age of the deceased married athlete was 57.15 years, while the mean age of the deceased unmarried athletes was h2.17 years. Removing all those who had met death by external violence, the mean ages are 57.90 years and h8.80 years. This was still in favor of the married athletes. This could be caused by a number of athletes dying of all causes before having a chance to marry. The latest and, one of the best, studies in this area of longevity was published in the British Medical Journal by Dr. A '4 Q LEA-‘b V'w‘asr- -.-‘ .. -W"‘r 25 Alan Rook,16 1958. A group of 83A Cambridge sportsmen were chosen to be in- Senior Health Officer at Cambridge University vestigated and information on 772 was secured. The control group numbered 761 men, and information on 710 was obtained. In this group of 710 there were 37h intellectuals, and the other 336 were chosen at random. The mean age at death of all sportsman and control groups, excluding those deaths due to war and accidents, are as fol- lows: Random.Control 67.k3 years; Intellectual Control 69.ul years; and Sportsmen 67.97 years. This study is very similar to Dublin's study published in 1932 on athletes, graduates and honor students.17 Rook's study also shows the mean ages of deaths of individual sports. Track and Field men have a mean age of 67.41 years; Cricketers 68.13 years; Rowers 67.08 years; and Rugby Footballers 68.8h years at death. Another interesting area of this study was the difference in the age at death between the heavy and light-weighted men. The author divided each sport according to the weights of the sportsmen, and then found the mean age of death for light group was 68.h6 years, and the heavy group was 66.73 years. The difference is slight, but it seems to be a trend that light-weight people live longer than heavy-weight people. 16Alan Rook, ”An Investigation into the Longevity of Cambridge Sportsmen," British Medical Journal, A865: 773-777, April, 195k. 17Dublin, 1932, 32. cit., pp. 5-7. 1"? 26 The causes of death in Rock's study are in Table XI.

This induced Verginella to believe that sportsmen are comparatively health- ier mentally than the non-athlete. 28 CHAPTER III METHODS OF PROCEDURE Introduction The results of studies that have been completed in the areas of longevity and morbidity of athletes from.many different regions of the world, have been presented in the preceding chapters to Show what has been com- pleted to date. The explanation of the procedure that was used in picking the subjects, and the methods used in sending questionnaires, follow-up letters, and tabulating of this data will be explained in this chapter. There will be an explana- tion of what statistical analysis will be used to clarify the results Obtained in this study. Questionnaire The questionnaire that was utilized in this survey was developed by a committee from.the Phi Epsilon Kappa fraternity for the purpose of investigating longevity and morbidity on a national basis (see Appendix A). Many different colleges and universities all over the country were to survey their athletes with this questionnaire to gain greater insight into these problems. The questionnaires were of two types: one for the athlete, and one for the non-athlete. The difference in the questionnaires was concerned with the general sports history of the athlete. There is a section on each questionnaire for a relative to fill in all the information 29 that could be found on a deceased subject. Some of the areas covered in the questionnaire are: 1. 2. 3. u. 5. 6. 7. 8. 9. 10. Athletes Weights at graduation and the present time. Marital status. Present state of health. Athletic and general sports history of the athlete. [ Activity during adult life, excluding playing parti- Hx .i‘.\r:.& cipation in sports. Military service. III—W n1¢ii* _ '1 Economic status from early childhood through adult life. Medical history. Smoking and drinking habits. Hereditary history. The track athletes included in this thesis have all earned a major letter in track at Michigan State sometime between 1886 and 1937. A permanent record of all athletes that earned letters at Michigan State is kept in the official files in the ticket office at Jenison Gymnasium. The information that was collected includes: (1) name and most recent address with the last date at this address; (2) the sport at which the athlete competed for his major award; (3) the year or years when these letters were won; and (A) the date of graduation, or the date of departure from.school. The next step was a double check on the addresses Of the athletes. This second check was made from.the official files 30 of the Alumni Office. These files keep an address of all persons who have graduated, or attended Michigan State. They also keep a record of the deceased alumni, and their last address. Many times their wives had attended Michigan State and had an address that could be used in contacting someone to fill out the questionnaire. A questionnaire was sent out to the last address listed by either the Alumni Office or the Ticket Office. The words "Please Forward" were typed on each letter to make sure every effort was made to contact the sub- “Wars—2x“ '1 ject or a close relative. Non-athletgg To make a better comparison between athletes and non-athletes, a group of college non- athletes were selected rather than using a set of insurance statistics which would compare a group of college men with the general populace. This group of college non-athletes was selected from the registration rolls in the Administration Office. A stratified random sampling was ,utilized to make the comparison more accurate. A non-athlete was chosen as a control for each athlete from.the first year that a major letter was won. This means an athlete who won a letter as a sophomore had a sophomore non-athlete chosen as a control for the study.- In picking these controls from.the registration catalogues, a subject was chosen by selecting every fifteenth name. If this control happened to be a girl, the next man on 31 this list was taken. The same procedure was used in finding the correct addresses for the control group as had been done with the athletes. Methods Used in. The addresses of all these athletes and MailingrQuestion- naires and Follow-gp controls were typed on envelopes. A Letters questionnaire, a return envelope and a letter were sent explaining the type of project in which they would be participating (see Appendix B). This letter explahled the possible importance this study could have on the future of sports and athletes. The questionnaires that were returned were placed in a file in alphabetical order, and the letters that were returned with incorrect addresses, or no forwarding address were re- checked to see if a mistake in typing, or a mistake in recording had been made. The letters that had been found in error were retyped with the proper address and name and re-sent to the subjects. Four weeks after the questionnaires were mailed, a follow- up letter was sent out in an endeavor to remind the subjects that they/had not as yet sent in their questionnaire (see Appendix C). In a further attempt to get more returns, a second follow-up letter was sent out two weeks after the first follow- up letter to those subjects failing to answer the previous cor- respondence (see Appendix D). This whole process did a great as? h} v—flh 32 \ deal to bring about a better percentage of replies to the questionnaires. There were 361 questionnaires sent out to the athletes, and the same number for the non-athletes. The athletes re- turned 210 questionnaires for a 57.6 percent return, and the non-athletes returned 165 questionnaires for a h5.3 percent return. The post office returned unopened, 63 questionnaires for the athletes, and 90 questionnaires for the non-athletes. This would raise the percentage of returns for the athletes and non-athletes to 69.7 percent and 60.2 percent respectively. Tabulation The questionnaires were all alphabetized and 2f,Results then numbered so the information could easily be tabulated in the correct area on the I.B.M. sheets. A coding system was devised for ease in recording this informa- tion. The data was then punched on I.B.M. cards. This would bring about a better statistical analysis of the results. A. groupcf 75 tables were devised to procure the information/that was to be dealt with in the comparison between the athletes and the controls. Statistical The statistical analysis of part of these data Analysis was made by using the critical ratio as a measure of significance. This was a ratio of the differences between the athlete and the non-athlete, divided by the probable error . "F, -—-—v 33 of that difference. The critical ratio is the technique that was used on all quantitative data in this study. The qualitative data were analyzed by the use of Chi- Square. This method of analysis was used when there was a need to know how the individuals distributed themselves in certain areas of the questionnaires, and a comparison between these distributions of the athletes and controls. The results of the statistical analyses are shown in the presentation of the findings reported in the following 35C“ Ira“ .6, tie m chapter. 3h CHAPTER IV RESULTS, INTERPRETATION AND ANALYSIS OF THE DATA The tables that were the products of the tabulated informa- tion from the questionnaires were statistically analyzed, and the results of this information are interpreted in this chapter.

A comparison of this type helps to validate the sampling technique in that the idea was to pick a control group of similar ages from the same college. The differences between ages of the deceased groups were not significant. QUE _ 7......

In analyzing these data, it was found that upon removal of all those subjects who died due to accidental causes the mean age difference dropped from.3.79 years to 2.h0 years. This is not significant in itself with this small number of cases, it; _; shrehi-d—fl but it is conceivable that with a larger number of cases 1 : .flf 25 ‘17!— 51': ' this could possibly be of some significance.

The other dis- eases occurred in the middle years and included cancer, vascu- IZTTW 1ar lesions affecting the central nervous system, pneumonia, intestinal obstruction, and several other diseases classified under all other diseases. A table with a greater number of cases BWtQum in“ would give a better concept of what the main causes of death might be in both.groups.

Chi square was used in the analysis of these data, and the poor and fair categories were combined due to the lack of numbers in these areas. The per- F contages are very similar in good, fair and poor health. This similarity is probably due to chance. . TABLE.IV (.11 .11.

The difference of h.69 pounds per man may not appear to be great, but it is close to I being significant. The change in weight from college to the present time was not significant, but it showed the athletes had gained an average of 2.62 pounds more per man than the non- athletes. The percent change in weight showed that DOD! Q ‘i’.’;.:-’ a ‘35 it!" ALAS: ’ ' i athletes have a slightly higher percent gain in weight. In reading the tables we must consider that even though the athp lete seems to gain more weight, it is the percent change in weight that tells the real story of how much.weight in rela- tion to body size is being gained. This percent change in weight seems to show that track athletes probably stay in a little better physical shape, even though the difference was not statistically significant.

The graph, Figure 1, shows this trend very well. The only exception to this inclin- ation was in the moderate sixty plus years. The athletes spent almost one hour more per day in physical exercise in their vocation and evocation than the non-athletes. The two cases that came close to being significant were the groups in the 30 - 39 mdld.and.h0 - h9 mild areas. These were criti- cal ratios of .08 and .09 respectively. These figures do not indicate a great deal of difference and may be due to athletes spending some of their spare time participating in some type of sports activity not included in their vocational and avo- cational activities.

This could be influenced by the physical well-being of the athletes and their ability to stand up under the rigors of training. The difference in th. mean {A number of years in service may have been determined by a a greater number of track athletes staying in service longer, a which seems to be borne out by the statistics. i There were twenty track athletes who stayed in the ser- E,- vice for six years or longer, and the mean number of years for the group of twenty was 13.9 years. The nonpathletes had only seven men stay in the service longer than six years, and this mean was 15.1 years. This large number of years included in the total group caused quite a difference in.mean years per man. The percentage of track athletes in service as compared to non-athletes showed a 12 percent difference between the two groups. In the statistical analysis of the information, a chi square having a probability between .05 to .02 was found. This could be caused by a more adventurous spirit for hazardous ‘ activities. They may have liked their training in the Reserve Officers Training Corps that all freshmen and sophomores were required to take well enough to enter the service. The difference in activity in service was not significant, but it would appear that a larger percentage of track athletes #3 were in vigorous activity during their military experience than non-athletes.

The athletes and nonpathletes are very similar in their answers to questions on the economic status that they main- tained during and after college. The differences are of very little consequence and, therefore, are not significant. The table does show that both groups were in better economic Status after college than they had been before college. There was a difference of 6.26 and 7.39 percent for non-athletes and track athletes respectively between college years and the years af- ter college. This is very logical because most people after college begin their careers and find a certain amount of success at whatever they are doing and would probably feel more secure in their economic status.

There were 12.h7 percent more non-athletes who did not use any alcohol through life than the athletes. The statistical analysis showed a probability of .02-.05. This difference could be caused by many different and varied reasons. The first COD! clusion reached on the significance of this information is the idea that after abstaining from.the use of alcohol during training athletes want to break training and this is one way. Athletes, many times, select jobs in areas of a more social nature, and therefore, use alcohol due to pressures of his clientele. The athlete may also use alcohol as a method of relaxing himself as a substitute for the physical exertion that he used as a means of releasing tension in.competition. The differences in smoking habits in Tables III and XXII were not significant, but indicate that the athletes seemed to #5 TABLE XXI A COMPARISON OF THE AMOUNTS OF TOBACCO USED BY TRACK ATHLETES AND NON-ATHLETES Tobacco *Track Athlete s {Non-Athletes Amounts 3‘ N 76 N No Response 12. 9 27 5 .5 9 F‘ Never 28 . 6 60 1L1. 8 69 Little 9.0 19 9 .7 16 Moderate 36 .6 77 31.5 52 A Heavy 12. 9 27 11.5 19 L. *Chi square (three degrees of freedom) 5.14.11 P I .20-.10 TABLE XXII A COMPARISON OF THE TYPES OF TOBACCO USED BY THE TRACK ATHLETES AND NON-ATHLETES- 6 —v T013000 *Track Athletes ”Non-Athletes Types . g N g N No Response Ltl.1 76 1411.8 714.

The difference between the no response groups was due to many of the subjects not indi- cating the type of tobacco that they used. The reasons for the differences between athletes and non-athletes possibly might be the same as those for the greater usage of alcohol. These reasons being the breaking of training and the more social type of job. Another possible reason might be that athletes many tunes turn to the sales and coaching profession. To relieve the tension of selling or coaching duties, they take up smoking and drinking habits. The diseases of track athletes and non-athletes during and after childhood were compared in Table XXIII and were found to be very similar. The groups were almost the same in percentage of tonsilitis and tensile removed. In.the area of heart defects, there was a difference of .9 percent in favor of the track athletes. The non-athletes had no chores at all while the athletes had 1.h percent. These were the main differences. There were so few cases of disease after childhood that no logical conclusion can be reached. The disease, hypertension, had the greatest number of cases and showed a difference of h.7 percent in favor of the non-athletes with.a mean age difference of 13 years. This is not signifi- cant because of the limited number of cases. This difference in hypertension could be caused by many of the events that were,: mentioned in regards to smoking and drinking. The social type of job athletes seem.to move into may cause this difference. TABLE XXIII DISEASES OF TRACK ATHLETES AND NON-ATHLETES DURING AND AFTER CHILDHOOD h?

The mean age at death of fathers were slightly higher than.mothers which is unusual from.the standpoint of statistics on this subject. The statistical analysis of these data showed no significant dif- ferences and therefore, was probably due to chance. 50 TABLE XXVI THE MEAN AGES AT DEATH OF THE MATERNAL AND PATERNALAGRANDPARENTS Track Athletes Non-Athletes C.R.

This same difference was shown in the mean age of death of the parents which.might be the cause of the difference in the length of life between the track athletes and the nonpathletes. A hereditary characteristic might pos- sibly be the cause of all these mean differences. Some of the parents and grandparents of the track athletes probably had a lower standard of living and had to work hard throughp out their lifetime. In all probability, many of the track athletes were from a lower income group and were only able to go to school through.the use of scholarships. 51 TABLE XXVII THE MEAN NUMBER OF BROTHERS AND SISTERS FOR TRACK ATHLETES AND NON-ATHLETES H Mean Number for Mean Number forc R P Track Athletes Non-Athletes ' ' - Sisters Living .91 1,08 1.35 .13 f“ Sisters Deceased 03h .20 1.33 .07 E Brothers Living 1.00 .78 1.85 .06 ; Brothers Deceased .33 .30 .51 .61 i Combined 2.56 2.36 i Track athletes had greater numbers in their families than the non-athletes, although the differences were not ex- treme.

The one great difference in these groups was in heart ailments. The percentage was twice as great among parents as it was among grandparents. This could possibly be due to the differences in diagnosis today from.what it was during the time of the {Isiah} -’-.' 'rt- u-v . a grandparents' deaths. This could also be caused by the ac- celerated life of today having caused a greater amount of heart ailment than that era of almost pioneer life of the grandparents of the athletes and non-athletes. In Table .XXVIII in the area of heart disease, the fathers of non- athletes had 12.6 percent more heart ailments than the fathers of track athletes. This was the one greatest difference be- tween the parents of these two groups. A chi square was computed for this table and there was no significant difference between these groups. Table XXII on the causes of death of paternal grandparents was statis- tically significant when a chi square was computed. The great- est difference seemed to be in the area of heart, vascular and renal diseases. The paternal grandparents of the track athletes had less heart disease when compared with the pater- nal grandparents of the non-athletes. 57 TABLE JDEXII THE OPINION 0F TRACK ATHLETES AND NON-ATHLETES 0N wEETHER ATHLETICS ARE HARMFUL . 0R BENEFICIAL To COMPETITORS _ Categories Track Athletes NonpAthletes N % N , % Harmful 5 2.37 15 9.09 Beneficial 108 51.u3 59 35.75 BR1333363631311 55 26.19 at 26.67 No Effect 19 9.05 11 6.67 No Opinion 2 .95 6 3.6a No Response 2 .96 15 9.09 ‘Deceased 19 9.05 15 9.09 The analysis of the data in Table XXIII was of some benefit because the Judgment of people is always interesting if not very scientific. The largest number of subjects tram ‘both groups thought that athletic competition was in the :main beneficial to its participants. A chi square was used and.it was found to be 13.hu for three degrees of freedom 1whichhas a probability of .007 for the differences between harmful, beneficial, beneficial with reservations and no ef- ;fect. This shows a significant difference between the ideas .or track_athletes and non-athletes on.whether athletics are detrimental to the competitor. The track athletes whose llurnrur . - ._ 58 expressed opinion that athletics were harmful, have probably been injured in athletics or have formed their impression through some person in connection with athletics. The non- athletes that believe athletics are harmful to those who compete may also have been injured or observed an injury to someone else in athletics. They may also have been disap- pointed in some attempt to become a letter winner. V 59 CHAPTER V SUMMARY, CONCLUSIONS AND RECOMMENDATIONS Summary The present study is a comparison between a group of track athletes taken from.the athletic record books at Michigan State University and a control group of non-athletes taken from.the undergraduate records in the Office of the Registrar. The track athletes were letter Imam-mind“; -"_»'i.- ' " ‘ I r winners from the years 1886 to 1937. The non-athletes were picked using a random.stratified sampling from.the same years that the athletes won their letters. A questionnaire was sent out to 361 track athletes and 210 questionnaires were filled out and returned. There 'were 63 questionnaires returned by the post office unopened. The non-athletes returned 165 questionnaires of a possible 361 with 90 questionnaires returned by the post office. The percentages for returned were 57.6 and.h5.3, respectively. During this process of receiving the questionnaires, there were two followbup letters sent out at intervals of .four and six weeks to accelerate the number of returns. The questionnaires were numbered for ease in tabulating this information on I.B.M. sheets and cards. A coding system :for entry of all information on I.B.M. cards was devised, and 'the information was punched onto these cards. {A group of 60 three cards per subject were needed for all the information that was used in the study. A group of seventy—five tables was obtained from the information that was taken from the questionnaires. These tables were then statistically analyzed for their results. There have been a few good studies completed in the area of longevity. The best of these was a study by Alan Rookl (19514.) on ”An Investigation Into the Longevity of Cambridge Sportsmen} In this study Rook used a control of similar non-sportsmen for a comparison between the two groups. He found very little difference in the mean ages at death of the random control group, but the intellectuals lived about two years longer. Louis Dublinz completed two studies, one in 1928 and his more complete study in 1932. He used a control group of college subjects in his second study to make his comparisons. Dublin used insurance statistics for his com- parisons in the first study, and this made the study less valid. Dublin found that there was not a great deal of difference in the mean age at death between sportsmen and non-sportsmen, but the honor men had a longer length of life, which was similar to the results of Hook's3 study. Most of the other studies . lilan.aook, ”An Investigation into the Longevity of Cambridge Sportsmen,” British Medical Journal, 11865: 773-777, ‘Prilg 195k. .. 2Louis I.

Conclusions The following statistically significant dif- ferences were observed. 1. Track athletes in college have a greater mean weight f‘ than college non-athletes. 2. Non-athletes spend less time in military service than track athletes. 3. A larger percent of track athletes enter military service than non-athletes. h. Non-athletes are more often non-drinkers of alcohol than track athletes. 5. It is the opinion of more non-athletes, as compared to track athletes, that athletics are harmful to the people active in this type of physical activity. 6. There are more sisters deceased from the families of track athletes than.nonpathletes. 7. There are more brothers living from.the families of track athletes than non-athletes. 8. Paternal grandparents of track athletes have less heart disease than the paternal grandparents of the non-athletes. 62 The following observations were not statistically signi- ficant. 1. There are more bnathers and sisters in the families of track athletes than in the families of non-athletes. 2. The sampling techniques used in selecting the non- athletes for this study seem to be adequate. F“ 3. There was no significant difference in the mean ages of death for track athletes and non-athletes. h. Accidental deaths seemio have occurred at a younger age than other causes of death for track athletes and non-athletes. 5. The economic status of track athletes and nonpathletes appears to have been better after college than during college. 6. Track athletes are users of tobacco more often than non-athletes. 7. The mean age of death of parents and grandparents of track athletes appears to be slightly lower than the parents and grandparents of non-athletes. Recommendations The recommendations that might help to better this study and future studies of this type are as follows: 1. A shmilar study should be made on all the athletes at Michigan State University with a control group of non-athletes similar to those that were used in this study. 2. 3. 63 The area of alcohol use should be more adequately defined in regard to amounts consumed. The questionnaire should have had a question on the occupation of both track athletes and non-athletes. To facilitate the I.B.M. work, the type of sport for every athlete should be punched into all three cards . 1mm_mufia§£ at? ( A I. D l 61+ BIBLIOGRAPHY Karpovich, Peter V.

It is a national study of longevity and morbidity of former college and univer- sity athletes. The potential value of such a study for the national health must be evident to all. Literally hundreds of thousands of boys and girls, youth, and adults participate annually in a variety of vigorous compe- titive sports. This participation is the result of both a strong natural urge and the ever increasing encourggement which is being applied by schools and colleges, clubs, and other organizations throughout the land. The findings of our national study will without question affect the future planning of sports programs everywhere, including those in which your own children and grandchildren may take part. Differences of opin- ion among laymen and among medical men as to the good and bad effects of competitive sports are common; so also are the fears of many parents of participants. It is high time that the real facts be established and made available to all. . In order to obtain the information so vitally needed, we are writing to allcf our former athletes who earned their letters during or before 1937. In the cases of deceased men, we are en'deavoring to get the facts from a close relative or friend. We are asking that you, along with all of our other former athletes, assist in this needed scientific stw by filling in the enclosed questionnaire form and returning it to us at. the earliest convenient date. Obviously, the complete cooperation of all is necessary: the results can be only as good as the degree of cooperation which is given. Accuracy and completeness of answers is of extremely great importance. Elm check with all persons and records which may help to insure correct answers. If there are any items for which you cannot find an answer, please write “Unknown". We wish to express in advance our thanks to you for your parti- cipation in this study. We are certain that when the results are published it. will be satisfying to you to know that you shared actively in the project.
