[Effect of an antioxidant on the resistance of the untrained body to maximal physical loading].

Administration of the synthetic antioxidant M-1 significantly increased the animals' resistance to exercise. The maximal duration of running was increased in the animals given the antioxidant. Meanwhile fermentemia that occurred after such an exercise was almost absent and the blood lactate concentration was 2 times less than in the control, the running durations being equal. The possibility of applying antioxidants for increasing the body resistance to exercise is discussed.
