The Claim
Resistance training improves gait speed in dynapenic older adults with low protein intake with large effect sizes, while nutritional supplementation alone produces only a moderate improvement in gait speed.
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, resistance training leads to greater improvements in walking speed than nutritional supplements alone.
See the scientific wording
Resistance training improves gait speed in dynapenic older adults with low protein intake, with large effect sizes, while nutritional supplementation alone produces only a moderate improvement, suggesting that movement-based training is more effective than dietary intervention for enhancing walking ability.
When older adults with weak muscles and low protein intake lift weights, their nerves send stronger signals to their muscles, making the muscles contract harder and faster. This increases the power of each step, allowing them to walk faster.
What the research says
1 studyIn older adults who are weak and eat little protein, lifting weights made them walk much faster, but just giving them protein supplements only helped a little. So moving your body works better than just eating more protein to improve walking.
