The Claim

In mobility-limited older adults with baseline leg velocity impairments, InVEST training produces a clinically meaningful improvement in mobility performance (SPPB increase of 0.73 units) compared to the National Institute on Aging's strength training program, although this finding did not reach statistical significance (p=0.05) and requires validation in a dedicated study.

In plain English

In mobility-limited older adults with leg speed problems, InVEST training results in a 0.73-point increase on the SPPB mobility test compared to the National Institute on Aging's strength training program, though the difference was not statistically significant.

See the scientific wording

Among mobility-limited older adults with baseline leg velocity impairments, InVEST training may produce a clinically meaningful improvement in mobility performance (SPPB increase of 0.73 units) compared to the National Institute on Aging's strength training program, although this finding did not reach statistical significance (p=0.05) and requires validation in a dedicated study.

Why this might work

When older adults move their legs quickly during standing or stepping tasks, their muscles fire more rapidly and recruit more muscle fibers, which generates more power. This increased power allows them to rise from a chair or climb stairs faster, improving their overall mobility.

  1. Study: Increased velocity exercise specific to task training versus the National Institute on Aging's strength training program: changes in limb power and mobility.

    For older adults who move their legs slowly, a special training program that focuses on moving fast (InVEST) might help them walk or stand better than regular strength training — but we’re not 100% sure yet. The study found a small but meaningful improvement in this group, which is promising but needs more testing.
