Lactic Acid Isn't The Enemy 🧪 #fitnessfacts #musclefatigue #science

It has long been thought that lactic acid is a harmful byproduct formed during exercise that causes muscle fatigue and soreness.However, close examination of shows that virtually no lactic acid appears in the body during exercise so it can’t cause fatigue. But research shows that the two products of lactic acid, lactate and acid, play separate roles during exercise and in the case of lactate are actually provide energy not reduce it. #lacticacid #lactate #musclefatigue #musclesoreness #fitnessfacts Reference: Cairns, S.
