From: Red muscle activity in bluegill sunfish Lepomis macrochirus during forward accelerations
Bluegill sunfish (N = 5) alter their red axial muscle activity during forward accelerations. (A) Burst duration decreases during acceleration and along the length of the body. (B) Duty cycle increases with acceleration and is higher in the anterior portion of the body. (C) The duration of overlap between left and right side activity increases with accelerations and is higher in the anterior body. (D) The fraction of bursts with co-activation (overlap greater than zero) increases with acceleration, particularly for the most anterior location. Color indicates location along the body. Acceleration groups and EMG locations labeled with different lowercase or uppercase letters, respectively, are significantly different from one another (p < 0.01). See Table S3 for statistical results.
