The assessment of normal values of muscle strength can be determined for the health outcome of adolescents, especially those who are living in a developing country.
The purpose of this study is to identify the relationship between anthropometric variables and vertical jumping performances. The jump height and the average of power were measured to establish reference values of vertical jumping parameters in Tunisian healthy adolescents aged 13-19 in both sexes.
Five hundred and twenty-five school adolescents (242 males and 283 females) were randomly selected to participate in this study. Maximum height and average of power reached in countermovement jump and squat jump were provided by an Optojump device. Full and stepwise regression models were used to identify which anthropometric parameters significantly contributed to performance variables.
All anthropometric parameters increased with age. Reference values and multiple prediction equations of vertical jump parameters were set based on a large sample of healthy Tunisian adolescents. The multiple regressions showed that age, mass, sitting height, waist size, fat-free mass and leg muscle volume for boys and mass for girls were the best predictors of jumping performances.
This study provides normative data for jumping performances in Tunisian healthy adolescents aged 13-19 in both sexes. The percentiles values are calculated to estimate the levels of adolescents with high or low jumping performances.
可以确定肌肉力量的正常值，以评估青少年的健康状况，尤其是生活在发展中国家的青少年。
本研究旨在确定人体测量学变量与垂直跳跃成绩之间的关系。通过测量跳跃高度和平均功率，建立突尼斯13 - 19岁健康青少年男女垂直跳跃参数的参考值。
随机选取525名在校青少年（242名男性和283名女性）参与本研究。Optojump设备测量了反向运动跳和深蹲跳中的最大高度和平均功率。采用全回归模型和逐步回归模型来确定哪些人体测量参数对成绩变量有显著贡献。
所有人体测量参数均随年龄增长。基于大量突尼斯健康青少年样本，设定了垂直跳跃参数的参考值和多元预测方程。多元回归表明，男孩的年龄、体重、坐高、腰围、去脂体重和腿部肌肉体积以及女孩的体重是跳跃成绩的最佳预测指标。
本研究提供了突尼斯13 - 19岁健康青少年男女跳跃成绩的规范数据。计算百分位数以估计跳跃成绩高或低的青少年水平。
