To investigate the acute effect of a t'ai chi chuan session on blood pressure and heart rate in patients with peripheral artery disease (PAD).
Design:
Randomized crossover intervention study.
Setting:
Outpatient therapy center.
Participants:
Seven patients with PAD, aged 50–79 years, not using β-blockers, calcium-channel blockers, or nondihidropiridinic vasodilators.
Intervention:
T'ai chi chuan and control session (both sessions lasted 40 minutes).
Outcome measures:
Systolic and diastolic blood pressure and heart rate, which were evaluated before and after the intervention (10, 30, and 50 minutes).
Results:
T'ai chi chuan exercise acutely decreased systolic blood pressure at 30 minutes after exercise (p = 0.042) and increased diastolic blood pressure at 50 minutes after exercise (p = 0.041). Heart rate did not change after t'ai chi chuan exercise.
Conclusion:
T'ai chi chuan acutely decreases systolic blood pressure in patients with PAD.
