Document Summary

Physical activity= any movement produced by muscles, increasing energy expenditure.

All adults should avoid inactivity-some pa is better than none. At least 10 min per episode, spread throughout. Include muscle-strengthening activities to include all major muscle groups on 2 or more days. Atp -> energy to do work + adp+pi. If no resupply of atp, muscle store =2-4 sec. Only enough stored in muscle for about 1 min. Aerobic utilization of 16-c fatty acid-108 atp. Amino acids can be used as fuel and to make glucose.
