Among the factors involved in neuromuscular co—ordination are: movC- ment of tne body at high speeds, quick directional changes, and fast 2 reactions to unexpected circumstances. These factors, plus others, are deemed by many physical educators, both men and women, as being essential for proficiency in various Sports activities. Although tradition, observation, and personal Opinion have in the past been the primary source for making these claims, experimental data have been collected upon male subjects to support these views. However, in studying the various qualities supposedly needed by women for success- ful performance, only a paucity of data are available dealing with the factors of reaction time and Speed of mowement. Statement of the Problem This study was primarily designed to compare the reaction time and arm movement time of selected women athletes with women non- atnletes at Richigan State University. Subproblems were: 1H.

With increased part1C1pa ion, physical education programs for women have be3n develc ped to include more diversified sports activities. Keepin pace with these trends,' sports costumes have been designed to allow more freedom of movement, Sports 3quW1pneu1t has been improved, play facilities have been enlarged, and teaching m 3thods have be en remodeled. Pr ysical educators are con- stantly striving for increased intelligent control and understanding of sports activities, and to give a scientific basis to many of our 4 present concepts and assumptions. Through the results of this study, scientific evidence may be found to repucliat or confirm the opinions .1. eat reaction time 1'4) and observations of many p1ysical educat rs that —- 3Jesse Feiring Williams, Pr incin ples of Plysical ducation (Philadelphia: W.

Limita ions of the Study At Kicnigan State University, only four sports-—tennis, fencing, Shfinaming, and field hockey--afford women ati1le tes the opportunity to compete on an inter collegiate level; but tno type and amount of competition is somewhat restricted. All the available subjects in .0 each of these Sports were tested. Ii more Sports had been available, the number of women comprizing the athletic group would have been larger and selection could have been made on an ability rather than membership basis. The level of ability necessary for membership on any team was subjectively designated by the presiding coach. This level varied from Sport to Sport and from individual to individual. Another limi- ta ion was the subjective ranking of playing ability by the coach of each Sport. here than one subjective ranking might have strengthened the study. It was the purpose of this study to test only movement of the dominant hand and arm, and not of the total body. This measure may not be as representative of movement time as would another type 0; measurement. Another limiting factor in this study was lack of the knowledge of the degree of psychological motivation exhibited by the nonathletic group. Through observation, it was the writer‘s opinion that the athletes demonstrated a greater degree of motivation than the nonathletes. The effects of constant, periodical, or nonexistent train- ing upon the athletic group may or may not have limited the results of Ufissumw Also, limiting the correlation of letter grades with individual reaction time and movement time scores, was the subjective grading system of each instructor. Letter grades were based, in part, on measures other than ability or skill. CdAPTEd II REVIEN OF NE LITERATURE To illustrate how important Speed of reaction and movement are in various Sports, typical views of coaches and physical educators are here expressed. "Speed is a word used to indicate various types of quickness or rapidity." In sports, it may refer to either quickness in seeing or in acting, but it usually refers to a combination of perception with 1 muscular action. Two qualities are thought to be necessary for good fencing: .. ' , . 2 (l) instantaneous judgment and (2) muscular strength and Speed. Of all women's Sports, fencing is the most attractive. "The average sports-loving American does not know that fencing is the fastest of all 3 ’5 Sports." Instantaneous responses by the muscles to commands o: the 4 brain are essential in fencing. 1John D.

A complete reaction may be divided into many parts. The physiological process may possibly follow this sequence: (l) sensory preception, (2) latency period in the sense organ, (3) conduction of the afferent nerve impulses to the proper sensory centers, (h) elaborations in the cerebral hemispheres and Spinal cord, (5) conduction of the efferent nerve impulses to the proper striated muscle, (6) latency period in the striated muscle, and (7) muscular response. Thomas K. Cureton would add strength, tone, and viscosity of the responding muscle _ . ie as factors affecting a Single response The factors determining the speed of reSponse in a simple reaction are undoubtedly very complex and include more than one organic vari- 17 ie 19 20 v‘ o o n o 1 ‘1 _ ‘ ‘ , , able.

A low correlation of .lu second was fou‘; id be tween reaction time and fifty-yard run times. A conclusion was that "fast reactors" are not "fast runners." "Contrary to po pular belief, individual differences in the reaction {irne function can be neglected except for verr short dis- tances, perhaps ten of fifteen yards at the most." 129 Shelby divided total reaction time into two phases, hesitation time and movement time. Hesitation time consisted of the interval between the stimulus and the beginning of the muscular response. This would be true reaction time. She concluded that reaction time tests for small muscles were more reliable than those for larger muscles. Through partial correlations, hesitation and movement times were identi- fied as independent factors in both the small and large muscle tests. The correlation of each of the e factors with a motor ability criterion was more significant than their intercorrelation. 150 Slater-Hammel investigated ne relationship of reaction time cl" 0 Speed of movem3nt. The subjects were twenty-five male physical edu- cation students. heasurements of reaction time of a visual stimulus and Speed of arm movement over a l20-degree arc were obtained. 129”ellesley Colle'e Studies in Hygiene and Physical Education, "heuromuscular Function andD Development," The Reseascn Q1Wacer1v Supplement, IX (March, 1938), pp. 37-45. 13081ater-Iiammel, "ieaction Time and Speed of Movement," loc. cit. 23 The mean reaction time of the cup was .Zah second; tie mean movement ‘7‘ 1‘ H time was .238 second.

The ball snatch apparatus consisted of reaction key, visual stimulus, and a tennis ball suspended by a strong twelve inches forward and upward from ther rea ion key. The action con- sisted of movinr the hand from the reaction key to the tennis ball, pulling it down. In the treaile press apparatus the subject moved his hand from the reaction key forward five and one-half inches to press a treadle. Two chronoscopes were used, one measured reaction time and the other total time. Movement time was computed by subtracting re- action time from total time. 3311 snatch mean measures wem‘ .1,) second for reaction time, and .121 second for move ement time Those for the treadle press were .216 second, mean reaction time, and .089 second mean movement time. From these two independent experiments, Henry demonstrated there was no correlation between reaction time and speed of movement. He concluded the two measures functioned inde- pendently. 132 In charging from the football stance, Miles measure d eighty- seven football players and found the average "charging" time of the 131Henry, "Independence of {eaction and Movement Times and Equi- valence of Sensory Motivators of aster Response," op, cit., pp. h3- 53. 1321-Iiles, 99. cit., pp. S-lli. 2'4 group to be . 359 se econd.

Records of muscle thickening latency were obtained by means of photo- graphing the string of a Cambridge g livanometer used in connection with an electrocardio; 3raph. hunning velocity was measured over a ten- yard course by timing the start and the finish. Action current electrodes on the “eacting muscle we3e used to obtain reaction time measures. An insijnificant correlation was found between velocity of movement and reaction time, also between velocity and muscle thickening latency. It was concluded txat muscle thickening latency is not a factor influencing the speed of muscle movement. The viscosity of the muscle appears to be the chief factor limiting speed of muscle movement. 133Stevens, op. cit., pp. 13 l— L dB. 134:2arick, QB Cit., pp. 02—10:. \3' 1 "Normal individuals with a high degree of motor aoi 'lity or skill and an averafe amount of strengthc annot increase their Speed of muscular performance to any appreciable extent." 135 Pierson con<3ucted a study wit:1 the purpose of investigating the differences between fencers and nonfencers with relation to various measures. These included Speed of arm mtvement, finger-press reaction time, and nova 3nt r3action time. iw Juty-ii'c male fencers and the same number of noniencers were tested in this study. In measuring arm movement time, the subject was instructed to hit a target placed eleven inches directly in front of him as fast as possible any time after hearing a "ready" buzzer. Finger-press reaction time was determined by instructinr3 tle subject to depress a telegraph key with his fingers upon receiving a visual stimulus. hovlement-reaction time was measured as the time elapsing between the introduction of a visual stimulus and the subject's response by moving the dominant hand felvard eleven inches. Pierson found in administc ring numerous trials that numbers twenty through forty occurred on a plateau. He therefore used these tw 3nty trials in corputing the mean for each subject. The mean movement time for the fencers was .137 second, for the nonfencers, .170 second. Finger-press mean reaction times for the fencers and nonfcncers were .217 and .230 second res fictively.

The subjects ranged in A age ircm seventeen to twenty- La years. Tile ave; ma e age of the non- athletes was nineteen years, while the average age of the athletes was nineteen and one-third years. All subjects maintained a freshman, sophomore, junior,or senior class status. The reaction time and movement time tests were administered during regularly scheduled class sessions during the la st tiree weeks of the spring term of 1553. All data were obtained between the hours of 9 a.m. and a p.m. Tests were conducted in the Wbmen's Gymnasium at Michigan State University. The apparatus was ' mt fllued in a large room. Physical aSpects of the room included one entrance door, various desks and chairs, electric lighting, windows lining two walls, and ample floor Space. Opportunities for external distractions were as controlled as possible and similar for all subjects. The st mulus and response units 'ere placed on a standard office desk seven feet from the recording and stimulus—producing units. Arrange:nent of the apparatus made it possible to place the subject within full View of the operator at all times. rocedure Each subject was tested individually. To facilitate the process, the subject and operator were locked within the testing room. x..\3 O Q The subject was requested to fill out a short personal data question— 2, naire. Assuming a comfortable position at the desk, facing the front of the stimulus and response units, the subject was given verbal in- a structions which emphasized the "muscular reSponse." The starting position was suanca“cizeo by directing each subject to place the middle fingers of her dominant Land on tile reaction key, holding it down, and to place nor Land and arm to the shoulder in a strm 3t line witn the; eaction Ke3 and target. To insure the proper preparatory set, an (f: electric buzze i was used to p1 es sent an auditory signal prior to th presentation of the visual stimulus. A short interval interceded the different stimuli. On appearance of the visual stimulus, the subject was instruot< ad to mov her hand iron tne reaction tte 3r directly forward toward the target and tr rou Qh tize beam of the electronic eye. This action constituted one mapletet rial. A careful demonstration of the desired re5ponse followed the verbal instruction.
