Does Style Matter: Comparison of Moderate- to Low-intensity Styles of Yoga
2026年8月11日 更新者：Caitlin Cheruka
Effects of a Single Evening Session of Vinyasa Yoga to Gentle Yoga on Sleep and Cardiovascular Health in Adults
The goal of this clinical trial is to learn if yoga works to improve sleep and heart health in adults with and without insomnia disorder. The main questions it aims to answer are:
- Does the style of yoga impact participants heart health overnight?
- Does the style of yoga improve participants sleep following a single session? Researchers will compare adults with insomnia disorder to adults with healthy sleep .
Participants will:
- Complete a moderate-intensity yoga practice, a low-intensity intensity yoga practice, and a quiet rest period while watching a nature documentary in the evening on three separate evenings
- Participants will have their sleep and heart health measured using a watch and heart rate monitor overnight following each visit
調査の概要
詳細な説明
This study investigates how two different styles of yoga, vinyasa yoga and gentle yoga, impact sleep and heart health in adults with and without insomnia. Insomnia, a common sleep disorder, increases the risk of heart disease, the leading cause of death worldwide. Recently, the American Heart Association identified poor sleep as a key factor in maintaining heart health, yet there is limited research on therapies that can simultaneously improve both sleep and cardiovascular function. By examining the immediate effects of a single evening session of yoga, this study aims to determine if yoga could serve as a practical, complementary approach to managing sleep and heart health.
Using a three-arm randomized crossover design, the study includes 42 participants, aged 18-40, who are either good sleepers or have diagnosed insomnia. Each participant will complete three sessions: one of vinyasa yoga, one of gentle yoga, and a non-active control session, with each session separated by a 72-hour washout period to avoid carryover effects. The yoga sessions will be standardized to 60 minutes and take place in the evening, approximately 4-6 hours before bedtime, under the supervision of a trained research staff.
The study has three main goals. First, examine whether different yoga styles influence heart function during sleep by measuring heart rate variability (HRV), a marker of nervous system balance that reflects the body's ability to regulate stress and relaxation. The investigators hypothesize that both yoga styles will improve HRV in people with insomnia more than in healthy sleepers. Second, to determine if vinyasa or gentle yoga improves sleep quality-measured by sleep efficiency (the percentage of time in bed spent asleep), total sleep time, and self-reported sleep quality-in adults with insomnia compared to those without sleep problems. Lastly, measure the impact of yoga on blood vessel function using flow-mediated dilation (FMD), a test that measures how well blood vessels expand in response to increased blood flow, with the expectation that vinyasa yoga's moderate intensity will provide greater immediate benefits compared to gentle yoga.

実験的：vinyasa yoga
60 minute moderate-intensity yoga session
|
Participants will follow a pre-recorded standardized sequence that includes a person demonstrating each sequence and provides verbal cues for the vinyasa yoga session.
The 60-minute vinyasa yoga protocol incorporated standing, seated, and supine postures and included the following order of sequences: integration, sun salutations, crescent lunge series, balancing, standing, back bending, and restorative series.
|
|
実験的：gentle yoga
60 minute low-intensity yoga session
|
Participants will follow a pre-recorded standardized sequence that includes a person demonstrating each sequence and provides verbal cues for the gentle yoga session.
This sequence focuses primarily on seated and supine postures and is designed to be accessible, safe, and restorative.
All poses are low-impact and supported using yoga blocks to promote comfort and reduce physical strain.
|
|
他の：Control Condition
60-minute non-active control condition
|
The non-active control session, participants will complete a quiet rest period while watching a nature documentary.
The film is educational in nature and has been carefully selected to avoid any graphic, distressing, offensive, or psychologically sensitive content.
It is commercially available and rated G for general audiences.
Participants will be asked to remain seated and refrain from the use of electronic devices.
A staff member will remain present to ensure participants following procedures.
