Exercise, Nutrition, and Combined Exercise and Nutrition in Older Adults with Sarcopenia: A Systematic Review and Network Meta-analysis
Abstract
It is unclear whether the combined effects of exercise and nutrition are better than those of exercise alone or nutrition alone in older adults with sarcopenia. This paper assesses the comparative effects of exercise, nutrition, and the combination of exercise and nutrition on muscle mass, muscle strength, and physical performance in older adults with sarcopenia. In this systematic review and network meta-analysis, 11 electronic databases were searched up to November 2020. Inclusion criteria were: (1) adults aged 65 years and older with sarcopenia; (2) interventions of exercise, nutrition, or the combination of both; (3) the outcomes include at least one of the following: muscle mass, muscle strength (hand grip and knee extension strength), or physical performance (gait speed and dynamic balance); and (4) randomized control trials. For each outcome measurement, a network meta-analysis was conducted to determine the direct and indirect effects of each intervention compared with each of the other interventions. A total of 26 studies were included in the network meta-analysis. Compared with the control group, exercise alone and the combination of exercise and nutrition significantly increased handgrip strength (1.12 kg, 95% CI: 0.12, 2.11; 2.03 kg, 95% CI: 1.10, 2.97) and improved dynamic balance (-1.76 seconds, 95% CI: -2.24, -1.28; -1.02 seconds, 95% CI: -1.64, -0.39). Both exercise alone and the combination of exercise and nutrition have beneficial effects on muscle strength and physical performance in older adults with sarcopenia.

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.
