Document Summary

Start from dead stop (requires strength and power) Time 5:30-8:00min: 80% is done aerobically, 20% is done anaerobically. Taller people generally have an advantage (bigger and stronger) Cho yields 5. 05kcals/lo2 yet stores only 4. 1kcals/g (cho) Fat yields only 4. 69kcals/lo2 but stores 9. 4kcal/g (fat) The more oxygen we consume, the more energy we get from the aerobic metabolism of the etc = more atp. Per litre of oxygen consumed, we get more energy from the carbohydrates (more efficient substrate) Per litre of oxygen consumed, we get less energy from the fat source. We get more energy from 1g of fat vs 1g of cho. We have enough energy to run to toronto based on the fat stores we have. They are used for sustainable events, tend to burn more fats during the day. Since 2. 7g of water is stored with every 1g of cho in the tissues than we only get.
