Document Summary
Stroke rate - contraction frequency of the muscle. Blood glucose depleted in minutes if not replenished. Muscle glycogen is s a series of glucose molecules bound together by water. 3 glycerol molecules that each have a fatty acid bound to them. Store tremendous amounts of energy that is available for body to use. Oxygen utilization reflects that amount of oxygen getting at end of metabolic pathway. Cho yields 5. 05 kcals/lo2 and sotres only 4. 1 kcals/g. 2. 7 grams of water stored with every gram of carbohydrate. 1g of carbohydrate s now a compound that is 3. 7 grams. When we store glucose as glycogen in body it gives us less energy: gram of stored glycogen is only giving us 1. 1 kcals/g of energy. Therefore, storing lots of enregy as carbohydrates doesn"t make sense. Since 2. 7 grams of water is stored with 1g of cho in tissues - we only ger. Fat yields only 4. 69 kcals/lo2 but stores 9. 4 kcal/g.
