What Is Sarcopenia — and Why Does It Matter?
Sarcopenia is the progressive loss of muscle mass and strength with aging. It raises the risk of falls, fractures, diabetes, and cardiovascular disease while reducing everyday function. Muscle mass declines at roughly 0.5–1% per year starting in the mid-30s, with the rate accelerating sharply after 60.
The Asian Working Group for Sarcopenia (AWGS 2019) uses grip strength (under 28 kg for men / 18 kg for women) and gait speed (under 1.0 m/s) as the primary screening criteria. Measuring these at home lets you estimate your risk before a formal medical evaluation.
Key Strategies to Prevent Sarcopenia
- Resistance training — 2–3x/week: squats, lunges, resistance bands (8–12 reps × 3 sets)
- Protein intake — 1.2–1.6 g per kg body weight per day (154 lb / 70 kg → 84–112 g/day)
- Vitamin D — sun exposure or supplementation (deficiency accelerates muscle loss)
- Fall prevention — balance exercises, remove floor hazards at home
Frequently Asked Questions
Muscle mass starts declining at roughly 0.5–1% per year from the mid-30s, accelerating after 60. Regular resistance exercise can preserve muscle mass even into the 70s.
Low grip strength is an indicator of reduced muscle strength but not a diagnosis on its own. Gait speed and muscle mass must also be assessed under AWGS 2019 criteria.
Resistance training (squats, deadlifts, resistance bands) 2–3 times a week, combined with adequate protein intake, is the gold standard for sarcopenia prevention and reversal.
