The effect of physical activity intervention and detraining on postmenopausal osteopenia and osteoporosis: a systematic review

Key Points

Regular physical activity significantly improves bone mineral density in postmenopausal women, especially in key areas like the lumbar spine.
Evidence from three included studies indicated that structured training sessions of 2–5 per week are effective in managing bone health.
Cessation of exercise leads to a gradual decline in the benefits achieved, emphasizing the need for ongoing physical activity.
Long-term engagement in exercise is crucial for preventing osteoporosis progression in postmenopausal women.

Abstract

Introduction Osteoporosis is a major health concern in postmenopausal women, and regular exercise is considered a key non-pharmacological strategy for preventing its progression. The aim of this systematic review was to evaluate the effects of physical activity and subsequent detraining on bone mineral density (BMD) in this population. Methods This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Three databases (PubMed, Web of Science, and Cochrane Library) were searched. A total of 1,161 studies were identified, of which 3 met the inclusion criteria. Results The findings suggest that regular resistance, aerobic, and HIIT training (2–5 sessions per week) can significantly improve or maintain BMD, particularly in the lumbar spine and proximal femur. Conversely, the cessation of exercise leads to a gradual decline in the achieved benefits within a few months. Conclusion The results emphasize the importance of long-term physical activity as part of osteoporosis prevention while also highlighting the risks associated with the interruption of structured training.
