Abstract

With the intention of studying for possible correlations of the length of the extremities with the athletic abilities (running, broad-stand-jumping, throwing and arm-bitting), the authors performed biometrical and athletic measurements on 6202 college girls (18 to 22 years of age) and 1205 middle and high school girls (12 to 17 years of age). The results are as follows.
1) The length of the lower extremity had a negative correlation with running ability in all age groups. The younger girls (12 to 13 years of age), who ran a 50 meter course, showed high negative correlation (ranging from -0.436 to -0. 177). In the older girls (14 to 22 years of age), who ran a 100 meter course, however, the correlation was almost negligible. Running a 100-meter-distance might be an unduly hard work for women and too long to test a explosive power of ari individual in the short running couse.
2) The length of the lower extremity showed a positive correlation with broad-stand-jumping. The correlation was much higher as compared with that in running.
This is suggested that the length of the lower extremity brings a higher correlation sensitively with the broad-stand-jumping as compared with that of running, which could be affected by the heart and other physiological factors involved in fatigue.
3) The length of the upper extremity revealed a positive correlation with throwing distance. When the habituated side was used for throwing, the correlation was low (0. 119 to 0. 193) in individuals aged
under 18, and almost negligible in the older group. When the unhabituated side was used, however, it was significantly higher in all age groups.
4) The length of the upper extremity was negatively correlated with arm-bitting frequencies. This negative correlation was low in the younger group and almost negligible in the older groups (over 17 years of age). In to the values of mean, there was a difference in arm-bitting frequencies as much as three times between shorter-arm group and !onger-arm group of college girls. This difference is very significant as far as entrance physical examination are concerned. It is suggested that muscular development follows in pace with the development of the upper extremity in length in younger individuals, however, it does not follows in olders.
5) These findings indicate that all correlations figures are higher in middle and high school girls than in college girls. One can presume that the college girls, in contrast to middle and high school girls, become less adaptable to physical exercises because of the pelvic inclination, the center of body gravity and other physiological changes after puberty.
6). judging from the above mentioned results, we are able to presume that the more we get a training of athletic exercise, the more the predominance by the length of the extremities give a large influences to the values of correlation in any of the items.
7) The currently effective physical ability standard approved by the Ministry of Education for the entrance examination is lower severely than the actual records of most candidates.
