The important factor during a workout is to keep energy levels high and delay muscle fatigue, especially by buffering lactic acid. Minimising free radicals (exercise increases the generation of free radicals – oxidative compounds that can damage muscle cells) and maintaining a proper electrolyte balance (which may reduce the chance of cramping) are key components as well.

Supplementation during both endurance and resistance training can increase athletic performance by replenishing glycogen stores and mitigating muscle damage; the result is greater training adaptations (structural and functional changes in the body i.e., the body adapts to the stress of increased physical work).
