摘要：The study was designed to examine the gender-related differences in maximum mechanical power output in various short-burst activities during growth. The subject sample consisted of four subgroups: 9 boys (14.11±0.6 yr), 9 boys (10.67±0.71 yr), 7 girls (14.29±0.49 yr), 7 girls (10.57±0.54 yr). We meausred peak power (PP), mean power (MP), fatigue index (FI) during 30-s WAnT, squat jump height (SJH) and power (SJP), and counter movement jump height (CMJH) and power (CMJP), maximum speed over 20-metre distance (S20). Lactation concentration was measured in the 3rd and 5th minutes after the WAnT. Ratio normalisation and ANCOVA were used to remove the influence of the differences in muscle (MM) and body mass (BM). Male adolescents had higher absolute values of PP (P Ratio normalisation showed that boys had higher PP/BM (P (P (P only in PP (P concluded that variations in body composition could not be the only key to gender-related differences in power output in short-burst activities.
