Numerous studies have shown creatine to be an effective supplement for increasing muscle size and strength when used in conjunction with a well-planned resistance training program. New research published in The Journal of Sports Medicine and Physical Fitness suggests increases in strength can be realized in as little as 2 weeks.
Young male subjects supplemented with 0.07 grams of creatine per kilogram of body weight per day during an 8-week weight training program. Some got a placebo, and all subjects performed 6 different exercises 3 days per week. Subjects in the creatine group started experiencing strength gains during bench press, leg press and shoulder press exercises after 2 weeks.
At the end of the 8-week program, compared to the placebo group, subjects who supplemented with creatine showed significant increases in strength for the bench press, leg press, shoulder press and triceps extension exercises, but not biceps curls or lat pulldowns.
