Description

Objective: To examine the feasibility and effects of an innovative exercise program, namely high intensity interval training (HIIT) for improving bone health in Hong Kong elderly women with osteopenia.

Hypothesis to be tested: HIIT group would gain more improvement in bone health, physical fitness and quality of life compared to non-exercise control group.

Design and subjects: It’s a single-blinded pilot randomized controlled trial study. A total of 48 community-dwelling elderly women (60-74 years) with osteopenia will be randomly assigned to the HIIT group or non-exercise control group. The HIIT group will receive a 24-week HIIT program (2 sessions/week, from 41min 40seconds/session to 47min 40seconds/session). The non-exercise control group will receive 24-week recreation workshops with the same frequency and time duration of HIIT program.

Main outcome measures: Participant recruitment data and adherence rates in the interventions will be collected. Bone health (bone mineral density using dual X-ray absorptiometry, serum bone turnover markers), physical fitness (aerobic endurance, muscular strength, flexibility, mobility and dynamic balance, and body mass index) and self-reported quality of life will be collected at the pre-intervention, post-intervention, and 6-month follow up stages.

Data analysis and expected results: Descriptive information will be used to report the feasibility. Generalized linear mixed models will be used to evaluate the intervention effects. It is expected that the HIIT program will be a feasible and effective exercise program in improving bone health among elderly women with osteopenia.
