Average amplitude of muscle activation across the 8 epochs surrounding the start of movement, which is the point between epoch 4 and epoch 5, for A, the gluteus maximus muscle; B, the medial hamstrings muscles; and C, the lateral hamstrings muscle. The activation of the medial and lateral hamstrings muscles was lower during the gluteal-cues condition than during the no-cues condition. a Indicates P ≤ .03. The activation of the medial hamstrings muscles was lower in epoch 8 during the hamstrings-cues condition than during the no-cues condition. b Indicates P = .028.
