Document Summary

Anaerobic concentrations: at 60 seconds, 50:50, after 60 seconds, it becomes more aerobic, any maximal effort under 60 seconds will become anaerobic. Increase fuel storage: sparing of cho - fatigue if deplete glycogen stores. Increase in mitochondrial size and number will give more enzyme activity: results in increased aerobic capacity, capacity increases over time and gradually levels off, duration and intensity are also important factors. Kreb"s enzymes: gastroc enzyme activity in untrained, moderately trained, and highly trained, enzyme activity increases with more training. How much is enough: at elite levels, some athletes spend 20-30 hours per week training aerobically. Exercise bout duration: aerobic capacity increases over time and gradually levels off, duration and intensity of exercise are also important influences, mitochondrial content increases with increased intensities but duration to sustain a particular work rate decreases. Cytochrome c: more cytochrome c results in more electrons that can be processed in the etc, greatest increase with high intensity.
