Mutsuhiro Nakao (2019) conducted an editorial in Stress. Tai chi and yoga vs. Control group was evaluated on Normalized HF (Hedge's g: 0.39, 95% CI 0.22-0.52). Tai chi and yoga increased normalized high-frequency heart rate variability compared to control, indicating enhanced parasympathetic relaxation.
