From: Jumping performance and muscle–tendon characteristics of Maasai men of East Africa
EMG ratios obtained during repetitive jumping (RJ). Ratio of averaged EMG (arbitrary units A.U.) in the braking phase relative to the pre-landing phase (left panels) and push-off phase relative to the braking phase (right panels). Submaximal RJ are depicted in upper panels, while maximal RJ is depicted in bottom panels. The pre-landing phase was defined as the 100 ms preceding first ground contact, while the braking phase was from ground contact to the instant of peak length of the GM-MTU (≈deepest point of BCM) during the stance phase, while the push-off phase was from the deepest point of BCM during the stance phase until toe-off. (GM; medial gastrocnemius, SOL; soleus, VL; vastus lateralis, TA; tibialis anterior). * Maasai vs. CON (P < 0.01).
