Document Summary

80-120 minutes at approximately 70% of vo2 max. If you"re preparing for a marathon, you need to run for a while. Improvement in stores of oxidative energy substrates and associated enzymes: atheletes can run longer but not faster (after initial training period -- beginners always get better) Up to 5 minutes at 95-100% of vo2 max. Improvement in stores of aerobic glycolytic energy subastrates and associated enzymes; increased lactate threshold; improvement in anaerobic enzyme stores and function; atheletes can run a little longer a little faster (increase in vo2 and lactate threshold) Making yourself fail - demanding so much oxygen that the body can"t do it - you"re demanding more energy. Marathon runners will do 1km intervals - stress the vo2. The body gets blood to the working muscle instead of digesting while working out. The ability of the heart to pump blood (q) The oxygen carrying capacity of the blood (hemoglobin content)
