一般认为，鱼用它们的前部肌肉组织产生稳定游泳所需的力量，而后部肌肉组织只将力传递到尾巴并做负功。孤立的红色肌肉束驱动通过长度的变化和刺激模式，肌肉通常在稳定的游泳过程中经历显示相反的模式。大部分的游泳力量来自肌肉在后面的区域的鱼，和相对较少来自前面的肌肉组织。此外，肌肉沿着鱼的长度的收缩特性显著地适于增强发电。
It is thought that fish generate the power needed for steady swimming with their anterior musculature, whereas the posterior musculature only transmits forces to the tail and does negative work. Isolated red muscle bundles driven through the length changes and stimulation pattern that muscles normally undergo during steady swimming showed the opposite pattern. Most of the power for swimming came from muscle in the posterior region of the fish, and relatively little came from the anterior musculature. In addition, the contractile properties of the muscle along the length of the fish are significantly adapted to enhance power generation.
