Strength training is ineffective for oxidative metabolism.
This study attempted to determine the relationship between strength training program effects and aerobic endurance adaptations. Strength training programs are generally considered to be anaerobic in nature. Endurance trained swimmers had an even higher fiber composition and capillary to fiber ratio than the other two groups. Strength training was not shown to affect the enzymes of oxidative metabolism which were increased in the swimmers. One should not expect to gain any endurance benefits from strength training when compared to endurance-trained athletes.
