Fig. 9. The relationship between the strain cycle and EMG activity at three points along the body of a trout during stage 2 of a fast-start. Data were obtained from the superficial anterior-pointing cone of the myotome at 0.35, 0.5 and 0.65FL, where FL is fork length. Strain is expressed as the percentage length change ±l₀, where l₀ is resting muscle length.
