Mechanical power output during running accelerations in wild turkeys.
We tested the hypothesis that the hindlimb muscles of wild turkeys (Meleagris gallopavo) can produce maximal power during running accelerations. The mechanical power developed during single running steps was calculated from force-plate and high-speed video measurements as turkeys accelerated over a trackway. Steady-speed running steps and accelerations were compared to determine how turkeys alt...

Maximum speed and mechanical power output in lizards.
The goal of the present study was to test the hypothesis that maximum running speed is limited by how much mechanical power the muscular system can produce. To test this hypothesis, two species of lizards, Coleonyx variegatus and Eumeces skiltonianus, sprinted on hills of different slopes. According to the hypothesis, maximum speed should decrease on steeper uphill slopes but mechanical power o...
متن کاملOld men running: mechanical work and elastic bounce.
It is known that muscular force is reduced in old age. We investigate what are the effects of this phenomenon on the mechanics of running. We hypothesized that the deficit in force would result in a lower push, causing reduced amplitude of the vertical oscillation, with smaller elastic energy storage and increased step frequency. To test this hypothesis, we measured the mechanical energy of the...
متن کاملMechanical Efficiency, Energetic Cost and Mechanical Work in the Human Running
This study aims at correlate Wmec and Cr with Eff. Twelve healthy men volunteered in the study. Wmec and Cr were measured during a treadmill running test which consisted in a rest period, incremental warm up and running test at 10km.h -1 . The biomechanical data, rest oxygen consumption (VO2) and exercise VO2 data were obtained. Relationships between variables were investigated using Pearson’s ...
