Maturity-associated variation in change of direction and dribbling speed in early pubertal years and 5-year developmental changes in young soccer players

摘要: Aim. The purpose of the current study was to assess developmental changes in change direction and dribbling speed youth soccer players taking into account skeletal age (SA), maturity status, body size, estimated fat mass, aerobic endurance, lower limb explosive strength annual volume training. Methods. Eighty-three male aged 10-15 years (SA) at baseline were annually followed over 5 years, resulting an average 4.4 observations per player. After testing for multicollinearity, multi-level regression modeling used examine longitudinal on speed. Results. Maturity-associated variability significant also among young 12-14 with better scores being performed by late maturers. Moreover, predicted Ion gitudinal improved SA (P Conclusion.
