Brief Summary

Insufficient physical activity and poor sleep are common in the adult population, but very few studies target physical activity and sleep in combination. The purpose of the Synergy Study was to test if physical activity and sleep quality can be improved in combination. 160 adults who reported insufficient physical activity and poor sleep quality participated in the study. 80 participants (intervention group) received access to a mobile app providing educational resources, goal-setting, self-monitoring, and feedback strategies, as well as 12 weeks personalized support including weekly reports, tool sheets and prompts. This group was compared against a waitlist group. After 3 months, between-group differences in moderate and vigorous physical activity were not statistically significant. However, significantly more participants in the intervention group engaged in 2 or more days/week of resistance training. The intervention group reported better overall sleep quality, subjective sleep quality, sleep onset latency, wake time variability, sleep hygiene, insomnia severity, and lower stress symptoms relative to the waitlist group. At 6 months, group differences were maintained for sleep hygiene, insomnia severity, and stress symptoms. Significant differences were observed for bedtime variability, sleepiness, daytime dysfunction and anxiety symptoms at 6 months, but not 3 months.
