Activité physique chez l’adulte en consultation de l’ostéoporose

Physical activity is a modifiable risk factor for osteoporosis. Studies on physical activity and bone health have mainly targeted postmenopausal women. Observational studies with fracture outcomes of physical activity interventions in adults older than 40 years found 11-40 % reduced risk of any fracture. There is no randomised controlled trials of exercise with fracture as a primary outcome. However, there is evidence that exercise can reduce fall-related fractures, particularly exercise that includes functional strength and balance training. Exercise recommendations to optimize bone health emphasize moderate-intensity or high-intensity progressive resistance training (PRT), and impact (weight-bearing activities) and balance training in order to reduce falls and improve bone mineral density. Indeed, multicomponent programmes that combine impact exercise with sufficiently dosed, moderate-intensity or high-intensity PRT and that are progressive in nature are the most effective. Professionals should avoid restricting physical activity and exercise unnecessarily according to age. People with osteoporosis should be encouraged to do more rather than less. Important themes for osteoporosis are: strong, steady and straight!
