Aim. The aim of the present study was to investigate the effect of sleep deprivation on shuttle run score (corresponding to an estimated V.#O2 peak) in middle-aged amateur athletes.
Methods. Twenty-two athletes, training 9.2 hours a week (±4), performed a Léger and Gadoury shuttle test daily in a 4-day series that included a pre-test in day 0, 28 hours without sleep before test 1 (and 10 another hours after the test and before bedtime for a sleep deprivation of 38 hours), and then 10 hours of sleep before each of days 2 and 3.
Results. Shuttle run score showed no significant difference over the 4 days; however, the change in shuttle run score on day 2 was significantly correlated with the initial score.
Conclusion. This result suggests that effect of sleep deprivation on shuttle run score is dependent on initial score and may encourage high level aerobic athletes to avoid sleep deprivation 2 days before a competition.
