简要总结
This study is designed as a two-group parallel randomized controlled trial (N=50) to test effects of 8-weeks of Qigong/Tai Chi (QTC) intervention compared to QTC plus HRVB on HRV parameters (primary), and cardiometabolic risk factors and sequelae (secondary) (e.g., BMI, waist circumference/percent body fat, sleep quality, stress, anxiety/depression, emotional regulation, eating behaviors, and cognitive performance).
详细描述
Heart rate variability biofeedback (HRVB) will be investigated as a target to optimize Qigong/Tai Chi (QTC) practices based on the expectation that learning to, and practicing changing heart rate variability (HRV) using HRVB, in addition to QTC, will result in higher levels of HRV and coherence than just the QTC alone. This study is designed as a two-group parallel randomized controlled trial to test effects of QTC compared to QTC plus HRVB on HRV parameters (primary), and cardiometabolic risk factors and sequelae (secondary). Fifty participants will be recruited and randomized to one of these groups and receive daily text prompts for 8 weeks to practice (using video links) Tai Chi Easy for 10-30 minutes (length of practice, the participants' choice). Half of the participants randomized to the HRVB enhancement will also be coached to practice HRVB to achieve coherence in their heart beat rhythms prior to practice (QTC plus HRVB group). Data collection at baseline and post intervention will assess body mass index (BMI, waist circumference/percent body fat, sleep quality, stress, eating behaviors, emotion regulation, mood (depression and anxiety), cognitive performance and changes in HRV parameters (high frequency power and coherence).

入选标准
- •31.5 inch or above waist circumference women
- •35.5 inch or above waist circumference men
- •Has a smartphone or tablet
排除标准
- •Those who are unable to stand for 10-minute segments (e.g., wheelchair or walker bound and too weak), and/or unable to walk
- •People who have been regularly practicing any form of meditative movement and or HRVB training regularly (i.e., 2 or more times per month for the past 6 months)
- •Individuals with diagnosed severe heart arrhythmias, heart transplant, or those with pacemakers would be excluded because either of those interferes with accurately assessing HRV parameters.
结局指标
主要结局
Vagal Tone
时间窗: 8 Weeks
Measured using resting Heart rate variability and computing parameters of high frequency power and coherence. Will be assessed with participants following a videoguide "to measure their heart rate" that helps them set up equipment and account, seated for 5 minutes of interbeat interval capture using the Inner Balance Bluetooth (HeartMath product) software and earlobe heart beat sensor.
