Age and physical function gains in older Veterans in the Gerofit exercise program
In 62 community-dwelling Veterans aged 60–99, a supervised exercise program was associated with improved lower extremity strength in all age groups, including ages 90–99; 8-foot up-and-go improved in younger groups but not in ages 90–99. [1]

Veterans aged 60–99 in a supervised Gerofit program
The study asked how age relates to physical function improvement after an exercise program for older Veterans. It analyzed baseline and 3-month follow-up data from 62 community-dwelling Veterans aged 60–99 enrolled in Gerofit, a supervised, individualized program with aerobic, resistance, balance and flexibility training. Participants were grouped by age: 60–69, 70–79, 80–89 and 90–99. Outcomes were lower extremity strength (30-second chair stands), mobility and balance (8-foot up-and-go) and cardiovascular endurance (6-minute walk).

Strength gains in all age groups; up-and-go not in ages 90–99
Across all participants, chair stand and 8-foot up-and-go performance improved significantly. Chair stand performance improved in all age groups, including adults aged 90–99. Improvements in 8-foot up-and-go were seen in younger age groups but not in participants aged 90–99. The abstract reports that the 6-minute walk result was not significant (p = 0.14). The authors conclude that participation was associated with significant improvements in lower extremity strength across all age groups, including the oldest.

Small 3-month sample; association, not causation
This was an analysis of baseline and 3-month follow-up data from 62 Veterans, so the follow-up period was short and the sample small. The findings describe associations between program participation and function; they do not show that exercise caused the changes. The abstract does not report a comparison group without exercise. Results for the 6-minute walk were not significant. The abstract is the only source reviewed here; the full text was not reviewed.

How to interpret this
Abstract only; the full text was not reviewed. The sample was 62 Veterans with a 3-month follow-up, and the abstract reports no exercise-free comparison group. Findings are associations, not proof of causation.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
