　　Heart rate is one of the most familiar and accessible gauges of exercise intensity. Health organizations state exercise intensity targets in terms of maximum heart rate， which is generally accepted as the value 220 minus the individual‘s age. The American Heart Association recommends that most individuals should exercise at an intensity around 50% of maximum when beginning an exercise program， and no more than 85% of maximum later.

　　Fitness buffs and athletes use finer gradations of heart rate intensity levels to achieve specific training conditions （see Table 1）。 At 72-78% of maximum heart rate， training crosses the threshold from aerobic to anaerobic training. Exercise below this level offers central cardiac system benefits such as improved cardiac output. Training above this threshold offers benefits to the periphery such as improved capillarization.

　　At 86-92%， training reaches the onset of blood lactate accumulation （OBLA）， where lactate builds up to significant levels with noticeable degradation in performance. Training at OBLA levels increases the individual’s ability to clear lactate and enhances muscle performance in well-trained athletes.
