- 4. Heart rate after a person has been sitting quietly for 15 to 20 minutes.
- 5. CR exercise that requires an intensity level of approximately 70 percent of capacity.
- 8. The highest percentage of VO2max at which an individual can exercise for an extended time without accumulating significant amounts of lactic acid, which forces an individual to reduce exercise intensity or stop exercising.
