The Claim

Resistance training improves physical function in dynapenic older adults with low protein intake, as measured by gait speed and timed up-and-go test, independent of changes in muscle mass or insulin resistance.

Source: Independent and combined effect of home-based progressive resistance training and nutritional supplementation on muscle strength, muscle mass and physical function in dynapenic older adults with low protein intake: A randomized controlled trial.

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
1 study reviewed
In plain English

In older adults with muscle weakness and low protein intake, resistance training leads to better walking speed and faster performance in standing up and walking a short distance, regardless of whether muscle size or insulin resistance changes.

See the scientific wording

Resistance training improves physical function in dynapenic older adults with low protein intake, as measured by gait speed and timed up-and-go test, independent of changes in muscle mass or insulin resistance.

Why this might work

When older adults with weak muscles train with resistance, their nerves learn to activate muscle fibers more effectively during movement, making walking faster and standing up from a chair easier without the muscles getting bigger.

  1. Study: Independent and combined effect of home-based progressive resistance training and nutritional supplementation on muscle strength, muscle mass and physical function in dynapenic older adults with low protein intake: A randomized controlled trial.

    Strength training helped older adults with weak muscles walk faster and get up from a chair more easily — even though their muscles didn’t get bigger and their blood sugar didn’t improve.
