Creatine May Help with Leg Strength, Sprint Times

NAVARRA, Spain--Creatine supplementation may help increase body mass, strength and sprint times, according to new research on handball players in the February issue of Medicine and Science in Sports and Exercise (34, 2:332-43, 2002) (www.ms-se.com). Researchers from the Investigative Center of Sports Medicine tested 19 handball players in a double blind, randomly assigned trial using 20 g/d of creatine for five days. Before and after supplementation, subjects performed half squats and bench presses for two sets of 10, followed by an open-ended set until exhaustion. In addition, jumping and sprinting tests were performed. No changes were observed in the placebo group in strength, running velocity or body mass measures. However, researchers found that creatine supplementation increased body mass, the number of repetitions performed until fatigue, sprint time and the average power output during half squats and bench presses. The researchers noted no improvement was found in upper-body maximal strength or in running endurance in the creatine group.
