Figure 2:Time-knee joint angle plots resulting from leg drop pendulum tests realised before and after the warm-up exercise in a moderately active control subject (20 years, 60.2kg, 157cm). Before the warm-up exercise, Amp1F was 1.55 vs 2.02rad after the warm-up. Before the warm-up exercise, FRI was 1.72 vs 2.07 after the warm-up.
