The VA program took 40 minutes to complete and included three phases: 1) activating qi and blood (5 movements, 10 minutes): warm-up exercises that allowed the body to accumulate heat and promote flexibility of the joints to loosen up the body, 2) punching meridians (14 movements, 20 minutes): both hands were used to exert a vibrating effect according to the rhythms that stimulate the 14 meridians in the entire body to improve aerobic endurance, and 3) relaxing body and mind (5 movements, 10 minutes): muscle relaxing exercises to rest the body and cease the qi. Participants in the experimental group received the VA program led by the instructors, who were trained and certified by the PI, 3 times per week and 40 minutes per session for 6 months.

Participants in the control group continued with their daily activities as usual.
