This study aimed to investigate the effect of maturity status on force-velocity relationships in a ballistic lower limb (BLL) test in high-level soccer adolescents and young adults. The population was 61 adolescents (13.0-17.9 years) and 23 young adults (18.0-26.2 years). Subjects completed the BLL test on a ballistic ergometer equipped with two force plates and a linear encoder. Following Samozino's method, maximal power output (), force () and velocity () were determined. An allometric model was applied to and with body mass (BM) and fat-free mass (FFM). Significant effects of maturity status were found for absolute , , relative to BM and FFM, relative to FFM and allometrically scaled to BM and FFM ( = 0.02 to < 0.001; = 0.10 to = 0.49). There was no significant effect for allometrically scaled to BM and FFM, relative to BM and . Body dimensions explain group differences in whereas for , qualitative factors explain the differences between the groups. As maturity status and body dimensions influence , these factors should be considered when assessing explosive short efforts. This could help to better identify potential athletic talent and adapt training content.
本研究旨在探讨成熟状态对高水平足球青少年和年轻成年人下肢爆发力(BLL)测试中力量-速度关系的影响。研究对象为 61 名青少年(13.0-17.9 岁)和 23 名年轻成年人(18.0-26.2 岁)。受试者在配备有两个测力板和线性编码器的弹道测力计上完成 BLL 测试。根据 Samozino 的方法,确定最大输出功率()、力()和速度()。对绝对、相对 BM 和 FFM 的、相对 FFM 的以及与 BM 和 FFM 等比缩放的()应用了一种比例模型(= 0.02 至 < 0.001;= 0.10 至 = 0.49)。与 BM 和 FFM 等比缩放的、相对 BM 的以及 没有显著的成熟状态效应。身体维度解释了 之间的组间差异,而对于,定性因素解释了组间的差异。由于成熟状态和身体维度影响,在评估爆发力短时间努力时应考虑这些因素。这有助于更好地识别潜在的运动天赋并调整训练内容。
