Implementing objective methods to assess physical performance has become an invaluable component of athlete or player development, monitoring, and talent identification in distinct sports. Many sports depend heavily upon muscular strength, muscle power output, and sprint performance, especially at competition level. Therefore, the aim of this study was to examine the relationships between 10-m time and several kinetic and kinematic parameters variables related to a weighted countermovement jump using a linear transducer in a large sample of trained sportsmen. A group of 32 trained sportsmen volunteered to participate in the study (mean ± SD: age 21.4 ± 1.5 years, body mass 67.5 ± 4.8 kg, body height 1.74 ± 0.02 m). The major findings of this study were the significant associations between 10-m sprint time and peak velocity during jumping (r = 0.630; p < 0.01); and also the nonsignificant associations between sprint and of force, mechanical impulse and rate of force development. These results underline the important relationship between 10-m sprint and maximal lower-body strength, as assessed by the force, power, and bar velocity displacement. It is suggested that sprinting time performance would benefit from training regimens aimed to improve these performance qualities.
实施客观方法来评估身体表现，已成为不同体育项目中运动员或选手发展、监测及天赋识别的重要组成部分。许多体育项目在很大程度上依赖肌肉力量、肌肉力量输出和短跑成绩，尤其是在比赛水平上。因此，本研究的目的是在大量训练有素的运动员样本中，使用线性传感器研究10米跑时间与几个与负重深蹲跳相关的动力学和运动学参数变量之间的关系。一组32名训练有素的运动员自愿参与该研究（平均值±标准差：年龄21.4±1.5岁，体重67.5±4.8千克，身高1.74±0.02米）。本研究的主要发现是10米短跑时间与跳跃过程中的峰值速度之间存在显著关联（r = 0.630；p < 0.01）；短跑与力量、机械冲量和力量发展速率之间无显著关联。这些结果强调了10米短跑与通过力量、功率和杠铃速度位移评估的最大下肢力量之间的重要关系。建议短跑成绩可受益于旨在提高这些表现素质的训练方案。
