| ABSTRACT | |||
| Nutrient administration following an exercise bout vastly affects
anabolic processes within the human body, irrespective of exercise mode.
Of particular importance are protein and carbohydrates whereby these two
macronutrients portray distinct functions as anabolic agents. It has been
confirmed that protein and/or amino acid ingestion following resistance
training is required to reach a positive protein/nitrogen balance, and carbohydrate
intake during recovery is the most important consideration to replenish
glycogen stores from an exhaustive exercise bout. Several factors play significant
roles in determining the effectiveness of protein and carbohydrate supplementation
on post-exercise protein and glycogen synthesis. Improper application of
these factors can limit the body's ability to reach an anabolic status.
The provided evidence clearly denotes the importance these two macronutrients
have in regards to post-exercise nutrition and anabolism. Therefore, the
purpose of this review is to discuss the impact of dietary protein and carbohydrate
intake during the recovery state on muscle protein synthesis and glycogen
synthesis. Key words: Protein supplementation, carbohydrate supplementation, anabolism. |
