Gregory Haff and associates from Appalachian State University, Boone, NC, found that, compared to a placebo, giving creatine supplements to track and field athletes who were involved in explosive strength training for six weeks improved vertical jumping ability and muscle mass. Subjects were given 0.3 grams per kilogram body weight (average of 22 grams per day), which is more than most experts recommend (five to 10 grams per day). The research team concluded that combining explosive strength training with high doses of creatine enhanced power performance and increased muscle mass in track athletes.
