Detailed explanation-1: -Lactic Acid Buildup Causes Muscle Fatigue and Soreness. Anyone who has pushed themselves through an intense workout will be familiar with “feeling the burn”-that sensation of fatigue and pain that sets in when you subject your muscles to lifting heavy loads repeatedly or sprinting all-out.

Detailed explanation-2: -This happens because oxygen can’t get to the muscle fast enough to keep up with the amount of energy the muscle needs. “When your muscles are making energy anaerobically, lactic acid is created as a byproduct, ‘’ says Dr. Hedt.

Detailed explanation-3: -Improper exercise, long time combat, military training and some related diseases (for example, cancer and stroke) can cause muscle fatigue, which negatively affects athletic achievement, military combat ability and patient recovery.

Detailed explanation-4: -Intracellular acidosis due mainly to lactic acid accumulation has been regarded as the most important cause of skeletal muscle fatigue. Recent studies on mammalian muscle, however, show little direct effect of acidosis on muscle function at physiological temperatures.
