PURPOSE: To assess the effects of 15 and 30-min naps on 3-km time trial performance and peak muscle strength. METHODS: Six recreationally trained college-aged participants visited the lab on 4 separate occasions. During each visit, participants completed a peak strength test, and a 3-km time trial following the nap condition. For the muscle strength test, peak isokinetic leg extension strength was assessed. The 3-km time trial was computer simulated time of completion and average power output was recorded. Nap conditions were: no-nap, 15-minute nap, and 30-minute nap. One-Way (nap condition) and Repeated Measures ANOVA’s (time x nap condition) were used to statistically analyze the data, with the level of significance set at pRESULTS: Neither the 15 or 30-minute nap had an impact on 3-km time trial finishing time or average power output when compared to the no nap condition. Though it did not reach statistical significance, peak strength tended to be impaired by the 30-min nap when compared to the 15-min nap (p=.075). CONCLUSION: A 15- or 30-minute nap has no effect on 3-km time trial finishing time, average power output, or peak strength performance, suggesting that napping prior to competition will not improve performance. Data should be gathered on a larger sample size and with naps of longer duration to definitively conclude that napping has no impact on performance.
