Final answer:
BCAAs, L-Glutamine, and B-complex vitamins are associated with aiding muscle recovery post-exercise. BCAAs contribute to building and repairing muscles, L-Glutamine supports the immune system, and B-complex vitamins assist in energy metabolism.
Step-by-step explanation:
BCAAs (branched-chain amino acids), L-Glutamine, and B-complex vitamins are dietary supplements that are often associated with aiding in recovery from intense physical activity. A primary role of BCAAs, which includes leucine, isoleucine, and valine, is their anabolic effect on muscles, meaning they help to build muscle by promoting muscle protein synthesis and reducing muscle breakdown.
L-Glutamine is the most abundant amino acid in the muscle and is believed to support the immune system, particularly for long-distance athletes, potentially aiding in quicker recovery. However, its effectiveness on muscle strength or mass has been disputed in some studies.
