In their study, Mendoza-Núñez et al studied the effect of Tai chi (TC) exercise on oxidative stress (OxS) in elderly with metabolic syndrome (MetS), with a painstaking study protocol.1 They included a total of 85 older sedentary adults with MetS. The control group did not participate in physical exercise (n=37), and the experimental group was enrolled in a TC exercise training program (n=48). They measured in both groups, in the pre- and post intervention periods, the cardiovascular parameters, OxS markers and inflamma¬tion markers. They concluded that a statistically significant decrease in HbA1c and a decrease in the OxS score were observed in the TC group compared with the control group. They did not observe changes in the cardiovascular parameters.
