Delayed-Onset Muscle Soreness (DOMS) describes a phenomenon of muscle pain or soreness that frequently occurs as a result of strenuous physical activity. DOMS occurs especially during the first few days after such activity. Because DOMS results in functional loss and related activity restriction, prevention and treatment are both important factors to recreational and competitive athletes, and to anyone who participates in vigorous exercises and activities of daily living. Lactic acid and its accumulation was once thought to be a major cause of DOMS, however this is not the case. Research suggested that blood lactate returns to resting levels within one hour of exercise even after extremely intense bouts of work. Thus the goal of this study was to determine the effects of two 10 minute thermal therapy between hot and cold, after an isotonic exercise, and the effect on blood lactate within a 30 minute interval.
