Pressure on the hand increased during head-first descent relative to horizontal locomotion but not as much as the pressure increased on the foot during ascent. This distribution of pressure...

...% smaller on average in sprinters than in non-sprinters ( P <0.001) whereas the sprinters' fascicles were 11%longer on average ( P =0.024). The ratio of fascicle length to moment arm was 50% larger in sprinters ( P <0.001). Sprinters were found to have longer toes ( P =0.032) and shorter lower legs...
