Document Summary

Vo2max: gold standard measurement for aerobic power. No single test adequately measures anaerobic power. Wingate test: most widely used test to measure anaerobic power & anaerobic capacity. Peak power output highest mechanical power achieved during the 1st 5-10s. Mean power output average power output over the full 30s. Total work = mean power output x 30s. Higher intensities: type ii fibers recruited to a greater extent while some type i fibers continue to be recruited. Increase in csa & % of type iia, iix fibers. Greatest change in # of type iia fibers. Lesser extent: increase in csa of type i fibers. Decrease in % of type i fibers. Shift of type i type ii: not seen with resistance training. Stimulated by activities that emphasize maximal muscle f-production for < 6s: sprinting; weightlifting. Experiment: 6s of knee-extension reps vs. 30s knee-extension reps at same resistance to fatigue. Both produced same strength gains & same resistance to fatigue.
