The Claim

Twelve weeks of whole-body resistance training performed three times per week increases leg strength, quadriceps muscle size, and type II muscle fiber cross-sectional area in active older men, independent of protein supplementation, indicating that resistance training alone is sufficient to induce significant musculoskeletal adaptations in aging individuals.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

If older guys who are already active do full-body strength training three times a week for three months, they’ll get stronger legs and bigger leg muscles—even without adding extra protein to their diet.

What the research says

1 study

  1. Study: Protein Supplementation after Exercise and before Sleep Does Not Further Augment Muscle Mass and Strength Gains during Resistance Exercise Training in Active Older Men.

    The study found that older men got stronger and built leg muscle after 12 weeks of weight training, whether or not they took protein supplements, showing that the exercise itself was enough.
