Intense exercise will cause exercise-induced muscle damage (EIMD) that leads to adaptations in the muscle that vary based on the type of athletic activity. Unfortunately, EIMD is the cause of delayed onset muscle soreness (DOMS).
With that said, your body uses the amino acid Leucine to fuel, repair, and adapt to intense exercise. One of the metabolites of Leucine is known as HICA.
HICA is used to limit the amount of muscle breakdown.
The prevention of muscle breakdown is anti-catabolic and results in less EIMD, less DOMS, and improved recovery and adaptations.
For Muscle Growth:
Scientific trials have shown that HICA supplementation in soccer players and wrestlers performing 2x and 3x a-day training increased lean muscle mass, while the placebo group actually lost muscle.
Scientific trials also indicate that HICA decreases delayed onset muscle soreness (DOMS) compared to placebo groups.
