Answer:
Reversibility means that an athlete can lose the effects of training when they stop, and can gain the effects when they begin to train again.
Detraining occurs within a relatively short time period after an athlete ceases to train. Performance reductions may occur in as little as two weeks or sooner.
In trained athletes, research indicates that detraining may result in greater losses in muscular power than strength. Strength losses are due to first to neural mechanisms, and next due to atrophy of muscles.
What is interesting is that strength levels after detraining are rarely lower than pre training levels, so training has a residual effect even when it is discontinued. But when the athlete returns to training, the rate of strength acquisition is high.
