Document Summary
College students get more activity than people with office jobs. A 30 minute jog and 3 10 minute jogs burn the same amt of calories. Exercise expends calories, regulates appetite, and increases bmr. Strength training has lower kcal expenditure than aerobic exercise. Anaerobic exercise is more intense, so atp must be reduced w/o oxygen. Aerobic is slow enough that the circulatory system can provide oxygen. Aerobic helps endurance and chronic disease/obesity prevention. Only carbohydrates can be used in anaerobic exercise. Muscle glycogen is used in the muscle its stored in as the body tried to conserve it. Anaerobic glycolysis is the predominate pathway for short events. Lactic acid decreases muscle ph & inhibits enzymes. Aerobic metabolism of glucose produces co2 and h2o as end products, w/ no accumulation of lactate. Fatty acids from subcutaneous, visceral, & intramuscular fat are all used during low intensity exercise. Amino acids may be used for gluconeogenesis during exercise to help maintain blood glucose.
