[The best physical therapy for osteoporosis]

Area of Science:

• Bone biology and metabolic diseases
• Gerontology and exercise science

Context:

• Osteoporosis and osteoporotic fractures represent a significant global health burden.
• Low bone mass leads to microarchitectural deterioration, reduced bone strength, and increased fracture risk.
• Physical activity is explored as a strategy to enhance and preserve bone mineral density.

Purpose:

• To evaluate the role of physical activity in osteoporosis management.
• To assess the association between exercise and bone mineral density.
• To determine the effectiveness of exercise in preventing osteoporotic fractures.

Summary:

• Cross-sectional studies indicate a strong link between exercise and bone mineral density, particularly in athletes.
• Potential self-selection bias exists, where individuals predisposed to larger bone mass may favor athletic lifestyles.
• While physical activity may reduce hip fracture risk in older women, its bone-building effects are modest compared to pharmacological interventions like bisphosphonates.

Impact:

• The findings suggest that exercise's primary benefit for osteoporosis may lie in fall prevention rather than significant bone mass augmentation.
• A comprehensive approach to osteoporosis prevention should integrate fall risk reduction strategies alongside exercise.
• Further research is needed to optimize exercise protocols for bone health and fracture prevention in aging populations.
