Abstract

In recent years, research investigating strategies to reduce exercise-induced muscle damage have become popular, with acute carbohydrate-protein supplementation gaining interest. The results of these studies are equivocal. A review of published peer-reviewed articles in reference to acute carbohydrate-protein supplementation and their impact on alleviating exercise-induced muscle damage is provided, in addition to an overview of the exercise-induced muscle damage process and rationale for their use. It can be concluded that there is potential for acute carbohydrate-protein supplementation to reduce some symptoms of exercise-induced muscle damage. Primarily, there is evidence of reduced increases in intramuscular proteins in serum and attenuated reductions in concentric muscle actions. However, there is little evidence of muscle soreness being alleviated. There are also substantial gaps in the literature, with information lacking in: (i) optimal dosage; (ii) optimal timing of supplementation; (iii) the effect on all paradigms of muscle function; and (iv) make-up of supplement(s), although whey protein concentrate and milk-based protein appear to provide benefits. Due to the conflicting results and the lack of studies conducted in this area it is difficult to provide definitive advice to the exercising individual. However, consuming carbohydrate-protein supplements would he recommended as they have demonstrated potential for reducing exercise-induced muscle damage and may be beneficial for other aspects of recovery.
