This study investigated the effects of squats and heel raises with extra loads on muscle function and cross-section with and without Galileo Training at 40Hz (20-40Hz, pos. 3-4, loads 80% 1RM (80kg), 3×8 squats (4 sec.), 3×12 heel raises, 6 weeks, 16 Sessions). The Galileo Group showed higher training effects with increases of muscle cross-section (up to +7%) and the speed indicator reactive ground contact time (-8%, Drop Jump)…
