Abstract

Background: Vertical jump is one of the most prevalent activities performed in volleyball. During adolescence, boys and girls undergo substantial changes in physiological and anthropometric characteristics that influence vertical jump performance. Objective: The purpose of this study was to examine and quantify sex and age-related differences in vertical jump performance assessed as vertical jumps height (VJH) and ground contact time (Tc) during repeated vertical jump tests within the Czech and Slovak population of elite adolescent volleyball players. Further aims were to compare the obtained results to non-athletic adolescent national normative data and investigate the relationship between basic anthropometric measures and VJH. Methods: The cross-sectional study was conducted on 203 females and 180 males from 13 to 19 years old. Statistical analysis of VJH differences between sex and age categories was performed using two-way ANOVA with Tukey's post hoc test. The relationship between basic anthropometric parameters and VJH were examined by Pearson's correlation analysis. Results: ANOVA showed statistically significant differences in VJH between males and females (p .05). Volleyball players have significantly higher VJH than non-athletes across all age categories and sex differences in volleyball players were smaller than the sex differences among non-athletic adolescents. A correlation analysis revealed only weak sex specific correlations of VJH with body height, body mass and BMI. Conclusions: The presented study showed significant sex differences in VJH between elite male and female volleyball players from the age of 15. VJH increases continually with increasing age in males. In females the effect of age on VJH was insignificant.

优秀青少年排球运动员垂直起跳发育:性别和年龄的影响

背景:垂直起跳是排球比赛中最普遍的项目之一。在青春期，男孩和女孩在生理和人体特征方面经历了实质性的变化，这些变化会影响垂直跳跃的表现。目的:本研究的目的是检查和量化捷克和斯洛伐克优秀青少年排球运动员在重复垂直起跳测试中垂直起跳高度(VJH)和地面接触时间(Tc)的性别和年龄相关差异。进一步的目的是将所得结果与非运动青少年国家规范数据进行比较，并探讨基本人体测量与VJH之间的关系。方法:对13 ~ 19岁女性203例，男性180例进行横断面研究。采用双因素方差分析和Tukey事后检验对性别和年龄类别之间的VJH差异进行统计分析。采用Pearson相关分析检验基本人体测量参数与VJH之间的关系。结果:方差分析显示，男性和女性VJH差异有统计学意义(p .05)。排球运动员在各年龄段的VJH均显著高于非运动员，且排球运动员的性别差异小于非运动青少年的性别差异。相关分析显示，VJH与身高、体重和BMI的性别特异性相关性较弱。结论:本研究显示15岁以上优秀男女排球运动员的VJH存在显著的性别差异。VJH随着男性年龄的增长而持续增加。女性中年龄对VJH的影响不显著。
