BCAA (Branched-Chain Amino Acids)
[bee-see-ay-ay]
/ˌbiː siː eɪ eɪ/
Noun
Branched-Chain Amino Acids (BCAA) are essential amino acids with a branched molecular structure, including leucine, isoleucine, and valine, that play a critical role in muscle protein synthesis and energy production during exercise.
BCAAs (Branched-Chain Amino Acids) are essential nutrients including leucine, isoleucine, and valine, crucial for muscle repair and growth. They bypass the liver and are directly metabolized in muscles, providing energy during exercise. BCAAs can reduce muscle soreness, decrease exercise fatigue, and prevent muscle breakdown. Runners may use BCAA supplements to enhance recovery and maintain muscle mass during intense training. Foods like meat, dairy, and eggs are natural sources. BCAAs matter to runners for improved performance, quicker recovery, and reduced muscle damage, especially during long-distance events.
