Abstract

Objectives The importance of strength training to elderly individuals is well established. However, the dose-response relationship of the benefits of strength training in this population is unclear. The purpose of the study was to use meta-analysis to investigate the dose-response of the effects of strength training in elderly individuals.Design Fifteen studies with a total of 84 effect-sizes were included. The analyses examined the dose-response relationships of the following training variables 'intensity', 'number of sets', 'weekly frequency', and 'training duration' on strength improvement.Methods The studies selected met the following inclusion criteria: (a) randomized controlled trials; (b) trained healthy subjects of both genders; (c) trained subjects aged 55 years or older; (d) strength increases were determined pre- and post-training; (e) use of similar strength evaluation techniques (strength determined by a repetition maximum test) and training routine (dynamic concentric-eccentric knee extension exercise to train the quadriceps muscle group). The effect-sizes were calculated using fixed and random effect models with the main effects determined by meta-regression.Results Many combinations of training variables resulted in strength increases. However meta-regression indicated only "training duration" had a significant dose-response relationship to strength gains (p=0.001). Over durations of 8-52 weeks, longer training durations had a greater effect on strength gains compared to shorter duration protocols.Conclusions Resistive training causes strength gains in elderly individuals, provided the training duration is sufficiently long, regardless of the combination of other training variables.

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.
