This study tested the immediate effect of Galileo Training on one-legged leg-press performance (only 1 leg on Galileo, other leg as control, 10x1 min., 1. min. rest, 26Hz, pos. 4, one-legged on toes, knee angle 100°-110°). Comparison between trained and untrained leg immediately before and after the training. The Galileo Training leg improved velocity and power in the leg-press exercise almost independent of extra loads by almost 10%. ..
