An ongoing study suggests that athletes who get an extra amount of sleep are more likely to have better performance, mood, and alertness.

These findings spring from an investigation involving five students on the Stanford University men's and women's swimming teams.

The participants maintained their usual sleep-wake patter for the first two weeks of the study, and then extended their sleep to 10 hours per day for six to seven weeks.

Their performance was assessed after each regularly scheduled swim practice.

It was observed that athletes swam a 15-meter meter sprint 0.51 seconds faster, reacted 0.15 seconds quicker off the blocks, improved turn time by 0.10seconds, and increased kick strokes by 5.0 kicks after having extra sleep.

"These results begin to elucidate the importance of sleep on athletic performance and, more specifically, how sleep is a significant factor in achieving peak athletic performance," said lead author Cheri Mah of the Stanford Sleep Disorders Clinic and Research Laboratory.

"While this study focuses specifically on collegiate swimmers, it agrees with data from my other studies of different sports and suggests that athletes across all sports can greatly benefit from extra sleep and gain the additional competitive edge to perform at their highest level," she added.

She and her colleagues observed that daytime sleepiness getting extra sleep also led to mood improvements, including higher ratings of vigour and lower ratings of fatigue.
