Abstract
本文旨在研究4～20歲難女生垂直跳的發展。四種不同學制別學生為受測對象，學生來自於鄉區之幼稚園、國中、高中和專科學校。1481男生和1448女生按年齡分成17組，每位受試者測兩次，較佳成績為研究資料。結果發現：（1）男生～17歲、女生4～15歲之垂直跳成績隨年齡提高，後隨年齡增加而降低；（2）男生17年齡組依次各歲間組做比較，計8組年齡比較成績差異達P＜0.01，3組比較成績差異達p＜0.05的差異顯著水準；（3）女生7組年齡比較差異達P＜0.01，1組達P＜0.05的差異顯著水準。
The purpose of this study is to investigate the development of vertical jump among male and female students at different ages. To be more specific, the developmental and level-off stages of vertical performance between 4 to 20 year-old subjects were examined. Four school levels of students were used as subjects. All students were selected from each of the following schools in rural area in Taiwan: kindergartens, primary schools, secondary schools and junior colleges. The subjects ranged from 4 to 20 years of age. 1481 male students and 1448 female students were divided into 17 subgroups by age. Each subject jumped twice. Better trial was considered the subject's score. The results showed that: (a) male students from 4 to 17 years old improved in vertical jump as they grew older, whereas female students showed improvement from 4 to 15 years of age. Both male and female students' performances started to level off after these years of age; (b) where the vertical jump performance in boys between age subgroups were compared, eight mean per-formances showed 1% significant improvement and 3 mean performances showed 5% significant improvement; and (c) in girls, however, 7 mean performances showed 1% signi-ficant improvement, and 1 mean performance showed 1% significant improvement as the age subgroups were compared.
