Understanding the Psychological Benefits and Neurophysiological Mechanisms of Qigong in Older Adults

Participants will receive 24 sessions of Baduanjin training over 12 weeks (2 sessions per week). Each session will last for 60 minutes. Baduanjin consists of eight forms of gentle movements, and it takes about 10 to 15 minutes to complete a full cycle. Participants will learn to practice each form gradually over the first 12 sessions. In the remaining 12 sessions, the participants will go through all the movements 2-3 times, with guided practice on rhythmic breathing and mind regulation (attention to body and breathing) to be performed in coordination with the movements. The training will be delivered by an instructor after training by the project team.

Participants will receive mindfulness-based intervention with the same duration and frequency as qigong group. The intervention incorporates psychoeducation on mindfulness and stress management and group-based mindfulness practice about breathing, awareness of body sensations, thoughts, stretching, and walking. All the mindfulness practices are based on publicly accessible audio recordings. The training will be delivered by an instructor after training by the project team.

Participants of the physical exercise group will receive training of a series of low-to-moderate intensity physical activities for the same duration and frequency as qigong group. The physical activities include stretching, flexibility exercise, balance exercise, and aerobic exercise. The training will be delivered by an instructor after training by the project team.
