...Ariel L. Camp; Elizabeth L. Brainerd ABSTRACT Suction feeding in ray-finned fishes requires substantial muscle power for fast and forceful prey capture. The axial musculature located immediately behind the head has been long known to contribute some power for suction feeding, but recent XROMM...

There was no significant...

...James C. Martin; Jennifer A. Nichols ABSTRACT Fish, birds and lizards sometimes perform locomotor activities with maximized muscle power. Whether humans maximize muscle power is unknown because current experimental techniques cannot be applied non-invasively. This study leveraged simulated muscle...

...Ariel L. Camp; Thomas J. Roberts; Elizabeth L. Brainerd ABSTRACT Suction-feeding fish rapidly expand the mouth cavity to generate high-velocity fluid flows that accelerate food into the mouth. Such fast and forceful suction expansion poses a challenge, as muscle power is limited by muscle mass...

To the best of our knowledge, there is currently no musculoskeletal model of a small primate that explains the mechanical output during jumping from the properties of muscle fibres and the way they are embedded in the musculoskeletal system.

...). Interactions between environment and gearing gave insight into muscle performance. Muscle F–L dynamics were highly sensitive to changes in either environment or gearing. Moreover, the effects of gearing on muscle power depended on inertial versus fluid loading, resulting in a significant environment–GM...

... wallabies would be able to generate substantial amounts of mechanical power. This was confirmed, as we found net extensor muscle power outputs averaged 155 W kg –1 during steady hopping and 495 W kg –1 during jumping. The highest net power measured reached nearly 640 W kg –1 . As these values exceed...
