Fig. 5: EMG activity (Tibialis Anterior and Biceps Brachii).
From: Hypergravity is more challenging than microgravity for the human sensorimotor system
A Mean normalized EMG activity of Tibialis Anterior (TA) and Biceps Brachii (BB) during reaching toward the far target for a typical participant in normogravity. The orange areas represent the temporal windows during which Root Mean Square (RMS) was computed. Mean RMS of (B) Tibialis Anterior and (C) Biceps Brachii as a function of Environment. Activity of Tibialis Anterior was lower in microgravity (0 g) than in normogravity (1 g) and hypergravity (1.8 g), and activity of Biceps Brachii was lower in microgravity than in hypergravity. Error bars represent standard deviation. **P < 0.01.
