We appreciate the excellent suggestion by Lin and Tzeng to investigate heart rate recovery after peak exercise. Heart rate recovery manifests the changes in autonomic tone that occur following cessation of exercise and has been shown to have prognostic significance, since abnormal parasympathetic-dependent deceleration is associated with increased risk of sudden death. Unfortunately, for this study, we do not have complete and reliable data on heart rate recovery because of nonstandardization of our postexercise procedures. We fully agree that it would be important to incorporate systematically in our ongoing and future trials, since it may yield important information about the role of tai chi in cardiovascular patients.
