... elicited a significant increase in power of both the SOL and the DIA relative to levels in a non-caffeine-treated control, the effect was not different between the experimental groups, despite the muscles of the trained group producing significantly greater muscle power. 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...

... 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...
