The Effects of Twelve Weeks of Tai Chi Practice on Anxiety in Stressed But Healthy People Compared to Exercise and Wait-List Groups-A Randomized Controlled Trial.

OBJECTIVE

This randomized controlled trial was undertaken to determine whether 12 weeks of Tai Chi (TC) practice can reduce anxiety in healthy but stressed people.

METHOD

Fifty participants were randomized into TC (n=17), exercise (n=17), and wait-list (WL) groups (n=16). Outcome measures used were State Trait Anxiety Inventory, Perceived Stress Scale 14 (PSS14), blood pressure and heart rate variability, visual analogue scale (VAS), and Short Form 36.

RESULTS

Significant improvements were observed from baseline for both TC and exercise groups for both state (p <0.01) and trait (p <0.01) anxiety, PSS14 (p <0.01), VAS (p <0.01), mental health domain (p <0.01), and vitality domain (p <0.01). Superior outcomes were also observed for TC when compared with WL for state and trait anxiety (p <0.01) and mental health domain (p <0.05).

CONCLUSION

TC reduces stress levels in healthy individuals and provides a safer, cost effective, and less physically vigorous alternative to exercise.
