The Claim
Resistance exercise performed twice weekly for 12 weeks increases 6-minute walk test distance by 21 meters and reduces systemic inflammation markers interleukin-6 and tumor necrosis factor-alpha in healthy active older men aged 67 years.
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 healthy active men aged 67, doing resistance exercise twice a week for 12 weeks results in a 21-meter increase in how far they can walk in 6 minutes and lowers levels of the inflammatory proteins interleukin-6 and tumor necrosis factor-alpha.
See the scientific wording
Resistance exercise performed twice weekly for 12 weeks improves physical function in healthy active older men aged 67 years, as measured by a 21-meter increase in 6-minute walk test distance and a reduction in systemic inflammation markers interleukin-6 and tumor necrosis factor-alpha.
Lifting weights makes leg muscles bigger and stronger, which lets a person walk farther. At the same time, the muscles release signals that calm down harmful body-wide inflammation, which also helps walking ability improve.
What the research says
1 studyDoing weight training twice a week for three months helped older men walk farther and lowered harmful inflammation in their blood, just like the claim said.
