Comparison of lower limb strength characteristics between youth and adult elite female team handball players

To analyse isometric strength and power–force–velocity profiling in youth and adult elite female handball players and to determine the differences in these capabilities according to age, anthropometric characteristics and playing positions. Twenty-one youths and 18 adults were tested in dynamic and isometric conditions. Power-load profiling was assessed from leg press using loads ranging from 30 to 90% of one maximum repetition. The maximal voluntary contraction and the rate of force development (times intervals 50–200ms) were analysed during isometric knee extension. A markedly difference was observed between youth and adult groups for their mechanical capabilities. Specifically the adult group's values were much higher than those of the youth players for power output at all loads tested (P
