Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
A recent review and meta-analysis, investigating the association between physical activity and osteoporosis prevention in elderly people, indicated that the traditional exercise interventions (i.e., resistance training) were undertaken for 60+ mins, 2-3 times/week for 7+ months. However, participation rates remain low in these exercise programs among older adults, in part due to a need for specialized equipment and correct techniques to prevent injury. In addition, low motivation and associated compliance with such conventional exercise is problematic among older adults.
Considering there is little evidence of HIIT benefits related to older women with osteopenia, the current study aims to evaluate the effectiveness of a 24-week HIIT intervention on bone mineral density, bone turnover markers and other health-related outcomes among Hong Kong Chinese older women.

High-intensity interval training (HIIT)
HIIT program for 24 weeks with a frequency of 2 times per week.
HIIT program for 24 weeks with a frequency of 2 times per week.
Participants will receive a 24-week HIIT program, with 2 sessions per week. Each session will comprise three sections, including warm-up, main exercise and cool down. The time will be between 37 to 40 minutes with progression of training. Each HIIT section will include six high-impact weight-bearing exercise. For Weeks 1-4, the HIIT section will include 12 intervals of 30 seconds HIIT workout at corresponding intensity, separated by 11 intervals of 60 seconds of active recovery. To ensure the subjects' safety, a chair will be used for assistance during training in the first month. Additionally, a 3 kg weight will be incorporated for the training in the final two months.
Non-exercise control
Participants will not receive any exercise training but will attend 48 recreation workshops.
Non-exercise control
Workshop participants in the non-exercise control group will receive a series of workshops related to daily recreation.
