Tai chi may help slow down age-related decline in muscle strength, according to Chinese investigators. A cross-sectional study was conducted in 205 long-term tai chi practitioners aged 60-89 and 205 age-matched controls. The strength of iliopsoas, quadriceps femoris, tibialis anterior and hamstrings in the tai chi group was higher than in the non-tai chi group. Muscle strength in the tai chi group was not found to not differ significantly between three age sub-groups (60-69, 70-79 and 80-89 years), suggesting that it can prevent the normal progressive decline in muscle strength associated with ageing. Muscle strength was correlated positively with number of years of tai chi practice.
