Aerobic exercise and sleep

TL;DRAbstract

The restorative and energy conservation theories of sleep predict that physical exercise will result in increased slow - wave sleep (SWS) and sleep duration. Restorative theories hypothesize that exercise creates a need for restoration, with a concommitant increase in SWS and sleep duration; while the energy conservation hypothesis holds that sleep, and SWS in particular, is a state of energy conservation, such that, any increase in energy expenditure caused by exercise should result in an increase in these components of sleep. Exercise may be acute (a particular exercise session), or chronic (physical fitness due to habitual exercise). Accordingly the effects of exercise on sleep may be a consequence of a particular exercise session, or physical fitness. The present literature does not show clear support for a facilitative effect of exercise on SWS or sleep duration. There is evidence however, that the effect of exercise may depend on the fitness and age of the subjects and the intens
