Using the specificity and overload principles to prevent sarcopenia, falls and fractures with exercise

Area of Science:

• Gerontology
• Exercise Physiology
• Geriatric Medicine

Background:

• Sarcopenia, falls, and fractures pose significant health risks for older adults.
• Effective prevention strategies are crucial for maintaining independence and quality of life in aging populations.

Approach:

• This narrative review synthesizes evidence from randomized controlled trials and systematic reviews.
• Focuses on exercise interventions, specifically resistance and balance training, for fall, fracture, and sarcopenia prevention.
• Considers principles of exercise physiology, implementation strategies, and potential effect modifiers like protein and creatine.

Key Points:

• Resistance training enhances muscle mass, strength, and physical performance, potentially preventing bone loss.
• Balance and functional training, emphasizing anticipatory and reactive control, are vital for fall prevention.
• Exercise programs should incorporate task specificity and progressive overload, with resistance and balance exercises performed at least twice weekly.

Conclusions:

• Structured exercise, particularly resistance and balance training, is effective in preventing falls, fractures, and sarcopenia.
• Future research should address implementation barriers to improve exercise adherence in older adults.
• Integrating protein intake and creatine supplementation may further enhance outcomes.
