Abstract

Objective Sarcopenia, an age-related decline of muscle mass, strength, and physical function, was associated with falls, frailty, and poor quality of life. The aim of the current study is to examine the effect of nutritional supplement containing whey protein, vitamin D and E on measures of sarcopenia.Methods A total of 60 sarcopenic older adult subjects participated in the current randomized, double-blind, placebo-controlled (iso-caloric control product) trial for 6 months. Muscle mass [Relative skeletal mass index (RSMI) measured by bioimpedance analysis (BIA)], muscle strength (handgrip strength), physical function (6-m gait speed, chair stand test, and timed-up-and-go test, TUG), quality of life (measured by Short-Form 36-Item Health Survey, SF-36), and blood biochemical indexes were measured before and after the 6-month intervention.Results Compared to placebo group, nutritional supplementation improves RSMI (mean difference: 0.18 kg/m 2, 95%CI: 0.01-0.35, P = 0.040), handgrip strength (mean difference: 2.68 kg, 95%CI: 0.71-4.65, P = 0.009), SF-36 mental component summary (SF-36 MCS) (mean difference: 11.26, 95%CI: 3.86-18.65, P = 0.004), SF-36 physical component summary (SF-36 PCS) (mean difference: 20.21, 95%CI: 11.30-29.12, P < 0.001), serum IGF-1 (mean difference: 14.34 ng/mL, 95%CI: 2.06-26.73), IL-2 (mean difference: -575.32 pg/mL, 95%CI: -1116.94 ∼ -33.70, P = 0.038), serum vitamin D 3 (mean difference: 11.01 ng/mL, 95%CI: 6.44-15,58, P < 0.001), and serum vitamin E (mean difference: 4.17 ng/L, 95%CI: 1.89-6.45, P = 0.001).Conclusion The current study demonstrated that the combined supplementation of whey protein, vitamin D and E can significantly improve RSMI, muscle strength, and anabolic markers such as IGF-I and IL-2 in older adults with sarcopenia. Further larger well-designed studies are warranted to evaluate whether long-term whey protein supplementation can blunt the declines of muscle function and mass 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.
