DOMS
Different activities could cause DOMS. The American College of Sports Medicine (2011, para. 5) acknowledged the complexities of the origin of the soreness and accompanying symptoms. The article highlighted that the soreness emanates from the microscopic damage of muscle fibers during exercise. The article listed activities known to cause DOMS as including jogging, jumping, and strength training exercise. Ma (GG, 43) added that muscle soreness emanates from intense, high exhaustive, and repetitive exercise. The acute muscle soreness that characterizes DOMS during or after exercise results from accumulating the exercise end products such as H+. Tissue edema could also be another cause of the soreness. According to the author the edema result from a fluid moving to the tissue from the blood plasma due to the insufficiency of the venous and lymphatic circulation.
The causes of delayed-onset muscle soreness becomes the foundation if the prevention and treatment strategies. Ma (2011, 44) noted the limitation of knowledge on DOMS. However, current research has denoted a connection between DOMS and eccentric muscle activity. During an intense muscle activity, the levels of specific blood enzymes such as myoglobin to 10 times from two. As a result of this change, structural damage may occur on the muscle fibers after an intense activity. Kraemer et al. (2011, 88) added that the experts attribute DOMS to tissue injury due to mechanical stress on the muscle and tendon. The micro tears on the muscle fibers disarrange the normal alignment of sarcomere.
