Amino acids are the building blocks of proteins, categorized as essential (must be consumed) or non-essential (synthesized by the body). Key examples for athletes include BCAAs (leucine, isoleucine, valine) for muscle repair and glutamine for recovery.
They play roles in protein synthesis, immune function, and energy production. For instance, leucine triggers mTOR pathways for muscle growth, while arginine boosts nitric oxide for blood flow.
Synonyms:
Proteinogenic amines, BCAAs (subcategory)
Benefits:
- BCAAs may reduce muscle soreness and fatigue.
- Glutamine supports gut and immune health during intense training.
- Arginine enhances vasodilation and nutrient delivery.
Sources:
- Dietary proteins (meat, dairy, legumes).
- Isolated in supplement form (e.g., powders, capsules).
Observations:
Timing: BCAAs often taken intra-workout; glutamine post-workout.
