The Claim
In mobility-limited older adults, both InVEST training and the National Institute on Aging's strength training program result in clinically meaningful improvements in mobility performance as measured by the Short Physical Performance Battery, with average increases exceeding 1.4 units, and there is no statistically significant difference in outcomes between the two programs.
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.
Among older adults with limited mobility, two different exercise programs—InVEST training and the National Institute on Aging's strength training program—both lead to measurable improvements in mobility, with an average gain of more than 1.4 points on the Short Physical Performance Battery, and neither program shows a statistically detectable advantage over the other.
See the scientific wording
In mobility-limited older adults, both InVEST training and the National Institute on Aging's strength training program produce clinically meaningful improvements in mobility performance, as measured by the Short Physical Performance Battery (SPPB), with average increases exceeding 1.4 units, despite no statistically significant difference between the two programs.
When older adults perform movements quickly during exercises, their muscles fire more rapidly and recruit more muscle fibers in a short time. This makes them generate more power — the ability to move forcefully and swiftly — which helps them stand up, walk, and climb stairs more easily. Even if their muscles don't get stronger, moving faster gives them better mobility.
What the research says
1 studyBoth exercise programs helped older adults with walking and balance problems get better at moving around, and neither was clearly better than the other. Everyone improved by more than 1.4 points on a standard mobility test.
