topicHmb Muscle Recovery Randomized Trial
claimPercent changes (Δ%) in functional tests were examined exclusively as exploratory correlates of redox adaptations.Supplementation was associated with attenuation of the placebo-related increase in oxidized glutathione and nominal preservation of the Glutathione Redox Index, although these effects did not remain significant after FDR adjustment.

topicHmb Muscle Recovery Randomized Trial
claimExploratory analyses indicated weak associations between changes in composite redox indices and Δ% functional measures.Creatine plus HMB supplementation was associated with nominal modulation of glutathione-centered redox balance during training in active older adults.

topicHmb Muscle Recovery Randomized Trial
claimDespite these benefits, the biological response to exercise is often dampened in aging due to reduced mitochondrial efficiency, lower anabolic sensitivity, impaired antioxidant capacity, and chronic inflammatory signaling.
