Abstract

OBJECTIVES: To assess the effects of an 8‐week exercise training program with a special focus on light‐ to moderate‐intensity resistance exercises (30–70% of one repetition maximum, 1RM) and a subsequent 4‐week training cessation period (detraining) on muscle strength and functional capacity in participants aged 90 and older. DESIGN: Randomized controlled trial performed during March to September 2009. SETTING: Geriatric nursing home. PARTICIPANTS: Forty nonagenarians (90–97) were randomly assigned to an intervention or control group (16 women and 4 men per group). INTERVENTION: Eight‐week muscle strength exercise intervention focused on lower limb strength exercises of light to moderate intensity. MEASUREMENTS: Primary outcome: 1RM leg press. Secondary outcomes: handgrip strength, 8‐m walk test, 4‐step stairs test, Timed Up and Go test, and number of falls. RESULTS: A significant group by time interaction effect ( P =.02) was observed only for the 1RM leg press. In the intervention group, 1RM leg press increased significantly with training by 10.6 kg [95% confidence interval (CI)=4.1–17.1 kg; P =.01]. Except for the mean group number of falls, which were 1.2 falls fewer per participant in the intervention group (95% CI=0.0–3.0; P =.03), no significant training effect on the secondary outcome measures was found. CONCLUSION: Exercise training, even of short duration and light to moderate intensity, can increase muscle strength while decreasing fall risk in nonagenarians.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
