Abstract:
While the extent of an athlete’s physiological adaptations varies due to a range of external factors, sleep deprivation has been proven to negatively affect one’s training and, ultimately, one’s overall athletic success. PURPOSE: This study investigates how both normal sleep and sleep deprivation affect an athlete’s recovery, overall skeletal muscle performance, and mental state. METHODS: Using a randomized-crossover design, healthy male and female individuals, with at least 1 year of experience in resistance training participated in this study. Exercise testing sessions were identical in nature and took place in the morning following either 3 consecutive nights of 8 hours of sleep (normal) or 3 consecutive nights of 5 hours of sleep (deprivation). Pittsburgh sleep quality index (PSQI) and profile of mood state (POMS) were collected each morning. Following warm-up, subjects performed the following tests in this order: 1 set of 15 repetitions of a maximal voluntary knee extension/flexion contraction at 300°•s-1, 4 repetitions of 4 seconds of isometric knee extension with EMG data collected, and 1 set of 50 repetitions of a maximal voluntary knee extension/flexion contraction at 60°•s-1. RESULTS: Between trials some variables in POMS and PSQI were statistically significant, the differences between trials in muscular performance were not as pronounced. CONCLUSION: Our hypothesis that sleep deprivation has adverse effects was partially supported, indicating that in an athletic setting, decreased sleep time might be detrimental with various types of athletic performance and one’s psychological well-being.
