For example, 15 s of rest between 10 sets of maximal cycling allow for maintenance of 86% of their peak power (Ratel et al.,2004) and with 30 s the peak power show no decline (Ratel et al., 2002a; 2002b). A high level of flexibility,
slower muscle fiber-type composition, and a high level of habitual physical activity in young subjects may help explain their higher recovery ability after high-intensity PT (Marginson et al., 2005)
