Fourteen female soccer players (U12) (FSP) competing in a regional league with 2 years of training and twelve untrained girls (UNT) volunteered to participate in the study. The sample size was estimated using G*Power software (version 3.1) The minimum sample size to yield a statistical power of at least 0.8 with an alpha of 0.05 and a large effect size (f = 0.8) is 12. The participants were free of any known neuromusculoskeletal impairments and lower extremity injuries within the previous year. The participants were instructed to maintain their habitual lifestyle and normal dietary intake before and during the study. The physical characteristics of participants can be seen in Table Physical characteristics of participants.Data are presented as mean ± SD. To estimate maturity status, the predicted age at peak height velocity (PHV) was calculated using the Moore equation (R
