Abstract

|
This study was from March 1st. of 1989 to June 30, 1990. The subjects of study consist of sportmen who are in attendance at high school or university and all samples are selected at random. The total number of subjects counts to 125 (Gymnastic: 13, Volleyball: 82) and the researcher measures and analyses the subjects´ physique, physician strength, the test of dominance eye, the lateral dominance tests of hand, foot, body and eye.
The results are as follows:
1. Physical growth and development
Mean values of physique showed in Table 2.
2. Physical fitness
Mean values of grip strength for male are 40.6 ± 3.3 for right side and 42.1 ± 5.1 for left side in sportmen of high school and 31.9 ± 3.6 for right side and 33.9 ± 4.1 for left side in female. Mean values of grip strength for male are 42.0 ± 4.8 for right side and 45.6 ± 4.3 for left side in sportmen of university and 32.9 ± 3.4 and 35.0 ± 4.6 for female.
Mean values of arm strength for male are 28.0 ± 3.1 for right and 30.9 ± 2.5 for left in sportmen of high school and 20.5 ± 2.8 and 21.5 ± 2.6 for female. Mean values of arm strength for male are 30.9 ± 3.4 for right and 32.5 ± 2.4 for left in sportmen of university and 21.9 ± 3.6 and 22.9 ± 3.3 for female.
Mean values of leg strength for male 35.4 ± 3.5 for right and 40.2 ± 3.6 for left in sportmen of high school and 24.8 ± 2.0 and 27.5 ± 1.9 for female. In sportmen of university, they are 40.7 ± 5.1 for right and 46.7 for left in male and 27.1 ± 2.8 and 30.3 ± 3.4 for female respectively.
3. Lateral dominance rate of hand, foot trunk and eye
As considered according to its function, the rates of right foot, left foot, both of feet in sportmen, total rates are each of 59.0 %, 32,5 %, 3.9 % for male and 64;7 %, 29.1 %, 4.2 % for female.
The rates of right side, left side both of sides in both of the sportmen in high school and university, the total rates are each of 52.6 %, 23.2 %, 9.5 % for male and 51.1 %, 27.3 %, 18.2 % for female.
The rates of right hand, left hand, both of hands in both of the sportmen in high school
unversity, the total rates are each of 52.6 %, 23.2 %, 9.5 % for male and 51.1 %, 27.3 %, 18.2 % for female.
The rates of right hand left hand, both of hands in both of the sportmen in high school and university, the total rates are each of 84.9 %, 11.4 % 1.6 % for male and 83.9 %, 13.4 %, 2.1 % for female, respectively.
4. Tests of dominance eye
As considered according to tests of dominance eye, the results of right eye and left in both of sportmen in high school and university, results are each of 62.9 %, 37.1 % for male and 58.7 % and 41.3 % for female, and 60.8 % and 39.2 % for both sexes.
