Captain America represented the pinnacle of human physical perfection. He experienced a time when he was augmented to superhuman levels, but generally performed just below superhuman levels for most of his career. Captain America had a very high intelligence as well as agility, strength, speed, endurance, and reaction time superior to any Olympic athlete who ever competed. The Super-Soldier formula that he had metabolized had enhanced all of his bodily functions to the peak of human efficiency. Most notably, his body eliminates the excessive build-up of fatigue-producing poisons in his muscles, granting him phenomenal endurance.
Abilities
Captain America had mastered the martial arts of American-style boxing and judo, and had combined these disciplines with his own unique hand-to-hand style of combat. He had also shown skill and knowledge of a number of other martial arts. He engaged in a daily regimen of rigorous exercise (including aerobics, weight lifting, gymnastics, and simulated combat) to keep himself in peak condition.
