Exercise interventions can increase bone mass and strength during growth, whereas this effect is attenuated later in life. Likewise, resistance exercise can increase both muscle mass and strength in younger subjects, but middle-age and older adults show increases in strength with less pronounced changes in muscle mass. This webinar will review current evidence on the impact of exercise and physical activity on muscle and bone strength in both the young and old, and discuss the clinical implications of these findings. The webinar will also address the cellular and molecular mechanisms underlying these observed relationships.
- Describe the impact of exercise interventions on muscle and bone in both the young and old.
- Discuss the cellular and molecular changes in muscle and bone with age that may alter the response of these tissues to exercise and physical activity.
- Appreciate the implications of these findings for the prevention of falls and bone fractures.
- Recognize additional therapies (e.g., nutritional, pharmacological) that could potentially augment, in a synergistic way, the effects of exercise on muscle and bone.
