Effect of pre-exercise and post-exercise creatine supplementation on bone mineral content and density in healthy aging adults.

Effect of pre-exercise and post-exercise creatine supplementation on bone mineral content and density in healthy aging adults. Exp Gerontol. 2019 Jan 29;: Authors: Candow DG, Forbes SC, Vogt E Abstract Creatine supplementation, immediately before and immediately following resistance training, has been shown to increase muscle mass and strength. However, the effects of pre- exercise and post-exercise creatine supplementation on aging bone mineral content (BMC) and density (BMD) is unknown. Using a double-blind, repeated measures design, aging adults were randomized to one of three groups: creatine before (CR-B: n = 15; 53 ± 3 years, 170.1 ± 9.9 cm, 77.1 ± 15.6 kg; 0.1 g·kg-1 creatine immediately before resistance training and 0.1 g·kg-1 cornstarch maltodextrin immediately after resistance training), creatine after (CR-A: n = 12; 55 ± 4 years, 173.4 ± 8.2 cm, 86.8 ± 20.1 kg; 0.1 g·kg-1 cornstarch maltodextrin immediately before resistance training and 0.1 g·kg-1 of creatine immediately after resistance training), or placebo (PLA: n = 12; 57 ± 7 years, 170.5 ± 10.5 cm, 77.9 ± 11.8 kg; 0.1 g·kg-1 cornstarch maltodextrin before and after resistance training). Whole-body resistance training was performed 3 days/week for 32 weeks. Prior to and following training and supplementation, BMC and BMD of the whole-body, limbs, femoral neck, lumbar spine, ...
