The Claim
Nutritional supplementation alone, without resistance training, produces only a moderate improvement in gait speed in dynapenic older adults with low protein intake, with no significant effect on muscle strength, muscle mass, or other physical function measures.
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.
In older adults with muscle weakness and low protein intake, taking nutritional supplements without doing strength training leads to only a small increase in walking speed and does not improve muscle strength, muscle size, or other physical abilities.
See the scientific wording
Nutritional supplementation alone, without resistance training, produces only a moderate improvement in gait speed in dynapenic older adults with low protein intake, with no significant effect on muscle strength, muscle mass, or other physical function measures.
When older adults with low protein intake get extra protein, their muscles use it to repair and refresh proteins more efficiently, which helps nerves communicate better with muscles during walking. This makes walking a little faster, but it doesn't make muscles bigger or stronger because there isn't enough physical stress to trigger growth.
What the research says
1 studyTaking protein supplements by themselves helped older adults walk a little faster, but didn’t make them stronger or help them stand up quicker. Only lifting weights made a big difference.
