The aim of this study was to determine the effects of an 8-week program of resistance training (RT) or suspension training (ST) on explosive strength in prepubescent boys.
Fifty-seven boys aged 10-11 years were assigned to 2 training groups, RT or ST or a control group (no training program). Boys trained twice weekly for 8 weeks.
A significant interaction was reported with a large (P < .001, ηp2=.463), medium (P < .001, ηp2=.395), and small effect sized (P ≤ .001, ηp2=.218) in the 1-kg ball throw, 3-kg ball throw, and time-at-20-m test, respectively. There was no significant interaction in the countermovement vertical jump or the standing long jump. Changes from preintervention to postintervention for the 1-kg ball throw were 5.94% and 5.82% for the ST and RT, respectively, and 8.82% and 8.14% in the 3-kg ball throw for the ST and RT, respectively. The improvement in the 20-m sprint was 1.19% for the ST and 2.33% for the RT.
Traditional RT and ST seem to be effective methods for improving explosive strength in prepubescent boys. ST could be considered as an alternative modality to optimize explosive strength training in school-based programs.
本研究旨在确定为期8周的阻力训练（RT）或悬吊训练（ST）计划对青春期前男孩爆发力的影响。
57名10 - 11岁的男孩被分配到2个训练组，即RT组、ST组或对照组（无训练计划）。男孩们每周训练两次，共8周。
在1千克球投掷、3千克球投掷和20米计时测试中，分别报告了显著的交互作用，效应量为大（P < .001，ηp2 = .463）、中（P < .001，ηp2 = .395）和小（P ≤ .001，ηp2 = .218）。在反向纵跳或立定跳远中没有显著的交互作用。从干预前到干预后，ST组和RT组在1千克球投掷中的变化分别为5.94%和5.82%，在3千克球投掷中分别为8.82%和8.14%。ST组在20米短跑中的提高为1.19%，RT组为2.33%。
传统的RT和ST似乎是提高青春期前男孩爆发力的有效方法。ST可被视为在学校项目中优化爆发力训练的一种替代方式。
