Effect of Vitamin D Supplement Consumption on Muscle Strength, Muscle Function and Body Composition in Vitamin D-deficient Middle-aged Women: A Randomized Clinical Trial
Background and Objectives: Sarcopenia is explained as the loss of muscle strength and muscle mass with aging‚ and is one of the major risk factors for metabolic diseases. Cross-sectional studies demonstrate that vitamin D is associated with sarcopenia in both men and women. The aim of this study was to investigate the effect of vitamin D supplement consumption on muscle strength, muscle f...
متن کاملVitamin D Status, Muscle Strength and Physical Performance Decline in Very Old Adults: A Prospective Study
Mixed reports exist about the role of 25-hydroxyvitamin D (25(OH)D) in muscle ageing and there are few prospective studies involving the very old (aged ≥ 85) who are at highest risk of low 25(OH)D, loss of muscle mass and strength, and physical performance decline. In the Newcastle 85+ Study (n = 845), we aimed to determine the association between 25(OH)D season-specific quartiles (hereafter SQ...
متن کاملVitamin D and skeletal muscle strength and endurance in COPD.
It is not known whether vitamin D levels make a significant contribution to muscle dysfunction in chronic obstructive pulmonary disease (COPD). In 104 COPD patients (mean±sd forced expiratory volume in 1 s 44±22 % predicted) and 100 age- and sex-matched controls, serum 25-hydroxyvitamin D (25(OH)D), 1,25-dihydroxyvitamin D (1,25(OH)(2)D) and parathyroid hormone (PTH) levels were measured and re...
متن کاملVitamin D deficiency and muscle strength in male alcoholics.
1. Chronic alcoholism may be complicated by proximal muscle weakness associated with a selective atrophy of type II skeletal muscle fibres. The histopathological findings are non-specific as identical changes are seen in proximal muscle weakness associated with various metabolic myopathies, including osteomalacia. 2. The maximum voluntary contraction (MVC) of the dominant quadriceps and plasma ...
