The Effects of Yoga and Quiet Rest on Subjective Levels of Anxiety and Physiological Correlates: A 2-way Randomized Crossover Design
In Brief
A clinical study evaluating YogaFit and Quiet Rest for Generalized Anxiety Disorder. Completed, enrolled 56 participants across 1 site.
Detailed Summary
A randomized repeated-measures crossover clinical trial was performed. Forty healthy, female college students completed a 30 min session of YogaFit and a time-matched seated rest condition on separate days. After each condition, participants viewed 30 min of emotional picture stimuli. State anxiety, heart rate and time-domain and frequency-domain measures of HRV were assessed baseline, post- condition, and post-exposure to emotional stimuli. Data were analysed using a condition x time (2 × 3) repeated-measures ANOVA.

Interventions
For YogaFit Vinyasa Flow (referred to as YogaFit in this manuscript)\], participants followed, via digital versatile disc, a standardized YogaFit format choreographed by an American Council of Exercise Certified and Registered Yoga Teacher (RYT). YogaFit was performed in the same laboratory setting and lasted 30 min. YogaFit is a westernized version of yoga that does not use Sanskrit terms (Shaw 2009). Breath was an integral part of every movement with specific breath rates for each phase of the session. The objective was to move the body with intention and purpose and be present in the body.
