In vivo Human Muscle Shortening and Oxygen Consumption

To determine the effects of muscle shortening on skeletal muscle energy requirement. 19 trained male and female runners (35+ or -2 years, 171+ or -2 cm, 67+ or -3 kg; VO sub(2)max=51+ or -2 ml times g super(-1) times min super(-1)) performed 30 plantarflexions attempting to reach 50% of maximum torq...

Contractions were performed on an isokinetic dynamometer under two conditions: isometric (ISO) and isokinetic (KIN). Compared to ISO, KIN resulted in significantly greater (mean difference+ or -SEM) muscle shortening (6.3+ or -1.9 mm, p
