Tai chi/yoga effects on anxiety, heartrate, EEG and math computations

Complement Ther Clin Pract. 2010 Nov;16(4):235-8. doi: 10.1016/j.ctcp.2010.05.014. Epub 2010 Jun 29.


Objective: To determine the immediate effects of a combined form of Tai chi/yoga.

Design: 38 adults participated in a 20-min Tai chi/yoga class. The session was comprised of standing Tai chi movements, balancing poses and a short Tai chi form and 10 min of standing, sitting and lying down yoga poses.

Main outcome measures: The pre- and post- Tai chi/yoga effects were assessed using the State Anxiety Inventory (STAI), EKG, EEG and math computations.

Results: Heartrate increased during the session, as would be expected for this moderate-intensity exercise. Changes from pre to post-session assessments suggested increased relaxation including decreased anxiety and a trend for increased EEG theta activity.

Conclusions: The increased relaxation may have contributed to the increased speed and accuracy noted on math computations following the Tai chi/yoga class.
