Sarcopenia prevention requires combining protein with strength training

Research indicates that protein supplementation alone is insufficient to reliably prevent sarcopenia, the age-related loss of muscle mass and strength that typically begins around age 50. While protein is a key component for regeneration, studies show that increasing protein intake without physical stimulus does not significantly improve muscle size or strength.

A twelve-month study involving 208 healthy older adults found that protein supplements provided no measurable advantage over carbohydrates regarding muscle mass and strength. However, significant benefits were observed when whey protein was combined with heavy strength training. This finding is supported by a review of 49 studies involving 1,863 participants.

Experts emphasize that maintaining muscle mass is vital for functional independence, aiding daily tasks such as climbing stairs, walking, and carrying groceries. To combat the effects of a sedentary lifestyle and age-related decline, a combination of nutrition, strength training, and coordination exercises is recommended.
