Efficacy of Creatine Supplementation and Resistance Training on Area and Density of Bone and Muscle in Older Adults
Abstract
Purpose: To examine the efficacy of creatine (Cr) supplementation and any sex differences during supervised whole-body resistance training (RT) on properties of bone and muscle in older adults. Methods: Seventy participants (39 men, 31 women; mean age ± standard deviation: 58 ± 6 yr) were randomized to supplement with Cr (0.1 g·kg −1 ·d −1 ) or placebo (Pl) during RT (3 d·wk −1 for 1 yr). Bone geometry (radius and tibia) and muscle area and density (forearm and lower leg) were assessed using peripheral quantitative computed tomography. Results: Compared with Pl, Cr increased or maintained total bone area in the distal tibia (Cr, Δ +17 ± 27 mm 2 ; Pl, Δ −1 ± 22 mm 2 ; P = 0.031) and tibial shaft (Cr, Δ 0 ± 9 mm 2 ; Pl, Δ −5 ± 7 mm 2 ; P = 0.032). Men on Cr increased trabecular (Δ +28 ± 31 mm 2 ; P < 0.001) and cortical bone areas in the tibia (Δ +4 ± 4 mm 2 ; P < 0.05), whereas men on Pl increased trabecular bone density (Δ +2 ± 2 mg·cm −3 ; P < 0.01). There were no bone changes in the radius ( P > 0.05). Cr increased lower leg muscle density (Δ +0.83 ± 1.15 mg·cm −3 ; P = 0.016) compared with Pl (Δ –0.16 ± 1.56 mg·cm −3 ), with no changes in the forearm muscle. Conclusions: One year of Cr supplementation and RT had some favorable effects on measures of bone area and muscle density in older adults.

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.
