The goal of this study was to examine the effects of low level activity during study sessions on academic performance in college students. Students in an introductory psychology course completed 2 hours of prescribed studying each week after their first exam. Individuals were placed in the Regular Desk group (58, 62.9% female) or FitDesk group (59, 62.5% female). The FitDesk is a stationary bike with a desk top attachment. Sleep quality was subjectively measured weekly across the semester and compared with class grades using a regression. Sleep quality predicted class grades (R=0.21, p=0.05). Further analysis found that FitDesk users with high sleep quality outperformed Regular Desk students with low sleep quality on their exams (p=0.05). Finally, an interaction between sleep quality and group suggested FitDesk use mitigated gradual decrease in sleep quality (p=0.05). These findings suggest increased light activity have positive effects on sleep quality and academic performance.
