|Title:||Development of Vertical Jump Performance Among 4-20 Year-old Male and Female students|
Office of Research and Development
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.
