Detraining is the loss of training or fitness adaptations due to prolonged abstinence from training or exercise. The time course of detraining is different for different physiological adaptations. Aerobic endurance is the quickest to detrain and strength training adaptations are lost much more slowly.

The word "detrain" can be used to mean the act of abstinence from training but it can also refer to the results of that abstinence. Although the two are often used interchangeably, detraining is not precisely the same thing as deconditioning.

Deconditioning normally expresses only the loss of adaptation and can be used for all circumstances including non-trained individuals. An example of this would be the loss of functional fitness of a bed-ridden individual or the muscle loss of astronauts in prolonged zero gravity environments.
