A small study (#0469) being presented later this morning as a poster adds to the growing body of evidence showing that sleep extension can improve athletic performance.
The study involved five members of the Stanford women’s tennis team. Extending their sleep to 10 hours each night was associated with significant improvements in measures of athletic performance.
They executed a faster sprinting drill and increased their hitting accuracy. Their daytime sleepiness and fatigue also decreased, and their vigor improved.
The results are consistent with similar studies previously conducted with Stanford athletes in other sports. An abstract presented at SLEEP 2008 involved men and women on the Stanford swimming teams.
