What Two Factors Determine the Metabolic Cost of Human Running?

Research Paper Title What determines the metabolic cost of human running across a wide range of velocities? Background The ‘cost of generating force’ hypothesis proposes that the metabolic rate during running is determined by the rate of muscle force development (1/tc, where tc=contact time) and the volume of active leg muscle. A previous study assumed… Read More

What are the Effects of Dual-task & Walking Speed on Gait Variability in People with Chronic Ankle Instability (CAI)?

Research Paper Title Effects of dual-task and walking speed on gait variability in people with chronic ankle instability: a cross-sectional study. Background Recent evidence suggests that impaired central sensorimotor integration may contribute to deficits in movement control experienced by people with chronic ankle instability (CAI). This study compared the effects of dual-task and walking speed… Read More

Battlefields: Speed & Surprise

“Rather than relying on defensive fortifications, he made brilliant use of speed and surprise on the battlefield, as well as perfecting siege warfare to such a degree that he ended the era of walled cities.” (Weatherford, 2004, p.xvii) Weatherford, J.
