Lactic Acid In Muscle: A Case Study

Decent Essays
Lactate threshold and the increase of lactic acid in muscles throughout intense exercise has become a major interest for athletes, coaches and clinicians, it is to be noted that lactate is ‘’the product of, not the cause of muscle contraction’’,(Myers, J et al, 1997).Lacate threshold gives a good insight as to how long an individual can endure a particular intensity. Resting value for amount of lactic acid is 1 mmol/liter. Just over a heart rate of 90% of the maximum gives a good estimate of threshold intensity. This 24 year olds maximal heart rate is about 176 bpm, therefore from observing the two graphs we can note that his threshold intensity occurs approximately at 210 watts.(high performance sports conditioning)
