Amino acids are important for muscle growth and regeneration. Athletes who are trying to increase their strength and muscle mass should pay attention to sufficient intake of amino acids through diet or supplements. A very important amino acid for athletes is BCAA (leucine, isoleucine and valine), which are essential amino acids that must be obtained from food. BCAA can help increase performance during training, support muscle growth and reduce fatigue.
Caffeine is a stimulant that helps to increase attention, endurance and performance. Caffeine is found in various foods and drinks, such as coffee, tea, cola and many energy drinks. Caffeine can be useful for athletes because it can increase energy, improve concentration and reduce fatigue.
