...Tim J. van der Zee; Arthur D. Kuo ABSTRACT Muscles consume metabolic energy for active movement, particularly when performing mechanical work or producing force. Less appreciated is the cost for activating muscle quickly, which adds considerably to the overall cost of cyclic force production...

.... This could be due to the fact that the energy required for calcification is a small fraction (1–3%) of the total metabolic energy demand and corals even under low food conditions might therefore still be able to allocate this small portion of energy to calcification. The response and resistance to ocean...

...Dominic James Farris; Jennifer L. Hicks; Scott L. Delp; Gregory S. Sawicki Experiments have shown that elastic ankle exoskeletons can be used to reduce ankle joint and plantar-flexor muscle loading when hopping in place and, in turn, reduce metabolic energy consumption. However, recent experimental...

... length indeed has much greater effect on both the mechanical work of the step-to-step transition (23% variation, P =0.04) and the overall energetic cost of walking (6%, P =0.03) than foot radius (no significant effect, P >0.05). We found the minimum metabolic energy cost for an arc foot length...

...Jiro Doke; Arthur D. Kuo SUMMARY We compared two hypothesized energetic costs for swinging the human leg quickly. The first cost is to perform mechanical work on the leg, and the second is to produce muscle force cyclically at high frequencies. Substantial metabolic energy is expended to perform...

... the ankles. Subjects therefore rolled forward on the foot surface much like dynamic walking models (e.g. Kuo, 1999 ; McGeer, 1990a ). We hypothesized that curved feet of small radius would result in high step-to-step transition costs, in terms of both work performed on the COM and metabolic energy...

...Jiro Doke; J. Maxwell Donelan; Arthur D. Kuo SUMMARY We measured how much metabolic energy is expended to swing a human leg. A previous dynamical model of walking predicted that increasing metabolic costs for walking with step length and step frequency trade-off against each other to determine...
