Scaling effects on muscle function: Power output of isolated fish muscle fibres performing oscillatory
Bundles of 3-10 live fast fibres were isolated from the abdominal myotomes of cod (Gadus morhua L.) 13-67 cm in length. The preparations performed work under conditions simulating their activity during swimming: sinusoidal length changes were imposed about in situ fibre length, and the fibres were s...
