High-Intensity Interval Training to Improve Bone Health and Fitness in Hong Kong Women Aged 60 to 74 with Osteopenia

What this Trial Is About

Osteopenia is a condition marked by low bone density that can lead to osteoporosis and increased risk of fractures, especially in older women. This research investigates the impact of high-intensity interval training HIIT on bone health and related outcomes in Hong Kong Chinese women aged 60 to 74. The trial aims to address challenges older adults face with traditional exercise programs, such as the need for special equipment and low motivation, by testing a 24-week HIIT program. Participants will be randomly assigned to one of two groups a HIIT exercise group or a non-exercise control group attending recreational workshops. The HIIT program involves twice-weekly sessions over 24 weeks, each lasting 37 to 40 minutes, including warm-up, main exercise with high-impact weight-bearing activities, and cool down. The exercise intensity and complexity progress during the study, with safety measures like chair assistance and added weights in later weeks. Throughout the trial, participants will undergo assessments at three points before the intervention, immediately after 24 weeks, and six months after completion. Measures include bone mineral density, bone turnover markers, physical fitness parameters such as muscle strength and aerobic endurance, fear of falling, and quality of life. This comprehensive evaluation helps researchers understand the effects of HIIT on bone health and overall well-being in older women with osteopenia.
