Exercise for Postmenopausal Bone Health - Can We Raise the Bar?

Area of Science:

• Gerontology
• Exercise Physiology
• Bone Biology

Background:

• Postmenopausal women face increased risk of falls, fragility fractures, and bone density loss.
• Exercise is a key non-pharmacological intervention for skeletal health.
• Understanding exercise's impact on bone mineral density (BMD) and fall prevention is crucial.

Purpose of the Study:

• To review the latest evidence on exercise's effects on falls prevention, BMD, and fracture risk in postmenopausal women.
• To explore mechanisms of exercise-induced BMD changes.
• To highlight innovative concepts for skeletal benefits from exercise.

Main Methods:

• Systematic review of current evidence.
• Exploration of exercise physiology hypotheses.
• Analysis of emerging concepts in exercise and bone health.

Main Results:

• Multimodal exercise with balance training prevents falls.
• Supervised progressive high-intensity resistance and impact training (HiRIT) increases lumbar spine BMD in postmenopausal women with osteoporosis/osteopenia.
• Potential mechanisms include myokines and extracellular vesicles, requiring further validation.

Conclusions:

• Exercise offers multi-modal skeletal benefits: HiRIT for bone building and balance training for fall prevention.
• Combination therapy of exercise and pharmacotherapy warrants consideration in future trials.
• Further research is needed on the durability and safety of HiRIT in specific patient populations.
