... this is consistent across different power outputs where the self-selected cadence (SSC) varies. We examined the effect of cadence and external power requirements on muscle neuromechanics and joint power during cycling. VL fascicle shortening velocity, muscle activation and joint-specific power were measured during...

... to a pressurized air source. Since our treadmill was not instrumented with force platforms, we could not compare joint powers using inverse dynamics for unpowered and powered walking to rule out redistribution of mechanical power. However, recent results from our lab indicate no difference in total ankle joint...

... and ankle. Muscle work was derived as the area under the joint power vs time curves and was partitioned into positive, negative and net components. Dependent t -tests were used to compare positive and negative work in level walking and net joint work between ascent and descent gaits on the ramp and stairs...
