The changes occurring in a person who reduces or stops physical training. If a person stops exercising completely, most training effects are lost within eight weeks; detraining losses in speed and agility are relatively slow, but flexibility is lost quickly. If exercise is continued at a moderate level, many of the beneficial effects are retained. Endurance levels, for example, can be maintained for several months by continuing a light exercise programme for 1 or 2 days a week. In addition, detraining is affected by the way people have acquired their training benefits. Those who have trained at gradually increased intensities over a number of years, tend to lose the training effects much more slowly than those who have trained intensively for only short periods.
