Effects of Combined and Classic Training on Diferent Isometric Rate of Force Development Parameters of Leg Extensors in Female Wolleyball Players: Discriminative Análisis Approach

The aim of this study is to verify the effects of the combined and classic training of different isometric rates of force development (RFD) parameters of legs. Materials and Methods: Three groups of female athletes was tested: Experimental group (N=12), classically trained group (N= 11), and control group (N = 20) of athletes. The isometric"standing leg extension" and"Rise on Toes" tests were conducted to evaluate the maximal force, time necessary time to reach it and the RFD analyzed at 100 ms, 180 ms, 250 ms from the onset, and 50-100% of its maximal result. Results: The maximal RFD of legs and calves are dominant explosive parameters. Special training enhanced the RFD of calves of GROUP …
