Activation phase (in degrees) and duration (proportion of cycle period T) of deep red muscle relative to the cycle of local strain,determined by comparing EMG burst activity to sonometric traces

Values are reported as means ± standard errors for the five fish that met data quality criteria. These fish averaged 45.0±6.6 cm fork length (L), and swam at 1.9±0.3 Ls–1 with a tail beat frequency of 3.2±0.4 Hz
