Abstract
- 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 (P<subscript>max</subscript>), force (F<subscript>0</subscript>) and velocity (v<subscript>0</subscript>) were determined. An allometric model was applied to P<subscript>max</subscript> and F<subscript>0</subscript> with body mass (BM) and fat-free mass (FFM). Significant effects of maturity status were found for absolute P<subscript>max</subscript>, F<subscript>0</subscript>, relative P<subscript>max</subscript> to BM and FFM, relative F<subscript>0</subscript> to FFM and F<subscript>0</subscript> allometrically scaled to BM and FFM (p = 0.02 to p < 0.001; $\eta $ η = 0.10 to $\eta $ η = 0.49). There was no significant effect for P<subscript>max</subscript> allometrically scaled to BM and FFM, F<subscript>0</subscript> relative to BM and v<subscript>0</subscript>. Body dimensions explain group differences in P<subscript>max</subscript> whereas for F<subscript>0</subscript>, qualitative factors explain the differences between the groups. As maturity status and body dimensions influence P<subscript>max</subscript>, these factors should be considered when assessing explosive short efforts. This could help to better identify potential athletic talent and adapt training content. [ABSTRACT FROM AUTHOR]
