Abstract

Sleep times and patterns are related to sport performance. Previous research suggests that sleep patterns contribute to differences in laboratory maximal effort treadmill tests, but little research has been done on maximal effort testing in the field. Further, research is lacking on whether sprint and acceleration times are correlated to sleep patterns. PURPOSE: The purpose of this study is to determine if a relationship exists between field performance testing and sleep patterns in female high school field hockey players. METHODS: Within the first week of pre-season training female high school field hockey players (n=15, age=15.47±1.06) completed a demographic survey, Pittsburgh Sleep Quality Index (PSQI) scale, and a seven-day sleep-wake journal using an online survey platform (Qualtrics, Provo, UT). Sleep latency, overall sleep quality, and duration of sleep were three PSQI measures chosen for analysis. The onset of sleep time and concentration were two measures used from the sleep-wake journal for analysis. A beep test and six 40m sprints with 10m splits were conducted within the first week of pre-season training, with 48 hours between each test. Beep test was a 20m multistage test that involved running in accordance to a pre-recording of beeps. Field tests were conducted on a level grass field under research supervision. An average of six 40m sprints and 10m splits were taken for analysis. RESULTS: PSQI revealed no participants suffered from sleep disorders. A Pearson correlation was conducted between performance and sleep pattern variables. A positive strong correlation exists between 40m average sprint time and 10m average sprint time (r= 0.896, p≤0.05). A negative correlation exists between onset of sleep and total sleep time (r= -0.598, p≤0.01). There were no correlations between performance and sleep pattern variables. CONCLUSION: These results indicate maximal effort field-testing does not correlate with sleep patterns in female high school field hockey players.
