We also explored whether sex modified the association between Tai Chi experts versus Tai Chi naïve and baseline functional measures.Another aim of the study was to explore, in an RCT, whether a short‐term Tai Chi training could show effects on physical measures in the naïve older adults. A total of 60 Tai Chi‐naive older adults were randomized into the Tai Chi group (
