ANATOMY

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: -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-3: -Lactic acid is created when the body turns glucose into energy. The production of lactic acid occurs when oxygen levels are low, generally during high-intensity exercise.

Detailed explanation-4: -By definition, a muscle begins to experience fatigue as soon as its maximal force or power capacity starts to decline. When the task involves sustaining a maximal contraction, the decline in performance parallels the increase in fatigue.
