Ageing is associated with a significant reduction in skeletal muscle carnosine, which has been linked with a reduction in the buffering capacity of muscle and in theory, may increase the rate of fatigue during exercise. Supplementing beta-alanine has been shown to significantly increase skeletal muscle carnosine.
In a 90-day double-blind placebo controlled study of twenty-six elderly men and women (52-90 years) who were randomly assigned to either a beta-alanine or placebo group, significant increases in physical working capacity at the fatigue threshold were found for the participants in the beta-alanine group.
It was concluded that beta-alanine supplementation improves muscle endurance in the elderly, and beta-alanine supplementation could have importance in the prevention of falls, and the maintenance of health in elderly men and women.
