This study will examine the effects of a 4-week vinyasa yoga program on sleep-related and cardiovascular outcomes using a randomized parallel group design. Following baseline assessments, participants will be randomly assigned into one of the two experimental conditions (i.e., vinyasa yoga, non-active control condition) based on stratification by sex (i.e., male, female) in a 1:1 ratio.~All groups will complete an initial in-person experimental session during the early evening: those in the vinyasa yoga group will be guided through a supervised vinyasa yoga session and those in the non-active control group will complete a quiet rest session. Participants will be provided an Actiwatch and heart rate monitor to measure acute experimental effects on sleep and nocturnal heart rate variability.~Following the initial supervised session, those in the vinyasa yoga intervention will be provided with a yoga mat and a standardized video and asked to practice 3 times per week for 4 weeks; compliance will be monitored by an online log. The non-active control group will not receive any yoga intervention and will be asked to avoid starting a new exercise routine.~Following the 4-week intervention, all participants will complete post-intervention sleep and cardiovascular assessments following the same procedures used at baseline.
The purpose of our study is to examine the effects of a 4-week vinyasa yoga program on sleep-related and cardiovascular outcomes in adults with insomnia symptoms. This study will examine the following aims:~To examine the effects of a 4-week vinyasa yoga program compared to a non-active control condition on subjective and objective sleep-related outcomes in adults who report insomnia symptoms.~To examine the effects of a 4-week vinyasa yoga program compared to a non-active control on cardiovascular health.~To examine the effects of a single session of vinyasa yoga compared to a non-active control condition on sleep- and cardiovascular-related outcomes collected overnight.~Researchers will compare the yoga group and the non-active control group to see if there are any improvements in sleep and cardiovascular health.
