PURPOSE: Evidence demonstrates that undergraduate students experience a chronic lack of sleep with 60% being qualified as poor sleepers. Additionally, poor quality and quantity of sleep and sedentary behavior has been shown to increase all-cause mortality in the general population. Given the high prevalence of poor sleep quality in undergraduate students raises the question of how various exercise modalities would affect the quantity and quality of sleep of undergraduate students. METHODS: A total of 23 college students were recruited. Participants were split into three groups: journaling (control), aerobic training (AT), and resistance training (RT), and completed three, 30-minute sessions of the intervention for three weeks. Two accelerometer and inclinometer devices were worn at baseline and the third week of intervention to track quantity and quality of sleep. Group x Time two-way repeated measures analysis of variance was employed to compare the differences in outcome variables across the three groups. RESULTS: There was no interaction effect between group and time on total sleep time, number of awakenings, average length of awakening, and sleep efficiency (p>.05). CONCLUSION: Three weeks of AT and RT compared to journaling did not have significant effects on undergraduate students’ sleep quality and quantity.
