虹鳟鱼和大口黑鲈在5到35°C的环境水温下，以每秒1到3个体长的固定游泳速度游泳。在稳定游泳时测量尾拍频率。尾拍频率和步幅（每次尾拍移动的距离）都随着游泳速度的增加而增加。在较高的水温下，鳟鱼尾拍频率较低，而在较高的水温下，鲈鱼尾拍频率较高。在鳟鱼和鲈鱼中，适应较高温度的鱼的尾拍频率较低。我认为，当测试温度高于驯化温度时，肌肉在力-速度曲线上运行较高；当测试温度低于适应温度时，肌肉在力-速度曲线上的动作较低。
Rainbow trout and largemouth bass were swum at fixed swim speeds from one to three body lengths per second at ambient water temperatures from 5 to 35 °C. Tail beat frequency was measured during steady swimming. Both tail beat frequency and stride length (distance moved per tail beat) increased with increased swim speed. In trout tail beat frequency was lower at higher water temperatures, whereas in bass tail beat frequency was higher at higher water temperatures. In both trout and bass tail beat frequency was lower in fish acclimated to a higher temperature. I suggest that when test temperature is above acclimation temperature the muscle operates high on the force–velocity curve; and when test temperature is below acclimation temperature the muscle operates low on the force–velocity curve.
