Operationalization
1 TREATED
Participants in the experimental group attended a 60-min Tai Chi practice session
twice a week for 24 consecutive weeks.
The style of Tai Chi implemented was a
condensed, classical Yang form, which incorporates elements of strength, balance, postural alignment, and concentration.
The sessions consisted of a 15-min warm-up, 30 min of Tai Chi practice, followed by a 15-min cool-down period. During the practice, participants were led by an instructor and
imitated, at a similar speed, the motions and postures of the instructor. Participants
were also encouraged to practice at home.

0 CONTROLS
were also encouraged to practice at home.
Participants in the control group received no active interaction during the 24
weeks of the study. They were instructed to maintain their normal routine activities
without starting new exercise programs and were told that they would receive a 4-week Tai Chi program at the end of the study.
