Intense exercise— particularly involving eccentric, lengthening contractions— damages muscle fibers and supporting connective tissue. While muscles may hurt right after the workout, peak soreness typically occurs during the next few days because of ) inflammation caused by tissue injury. This involves the buildup of pro-inflammatory chemicals which cause pain, swelling and decreased performance. Muscle damage and inflammation are particularly bad following prolonged, high-intensity competitions such as triathlons and marathons. A Brazilian study found that creatine supplementation (20 grams per day for five days) before a triathlon reduced the inflammatory response following the competition compared to a carbohydrate placebo (fake creatine). Creatine supplements improve the cell energy supplies by increasing creatine phosphate levels. This might reduce muscle cell death associated with extreme inflammation caused by competing in strenuous, prolonged athletic competitions such as triathlons.
