Creatine supplementation and sprint performance in soccer players.
PURPOSE This investigation examined the effects of creatine (Cr) supplementation on intermittent high-intensity exercise activities specific to competitive soccer. METHODS On two occasions 7 d apart, 17 highly trained male soccer players performed a counter-movement jump test (CMJT), a repeated sprint test (RST) consisting of six maximal 15-m runs with a 30-s recovery, an intermittent enduran...
متن کاملEffect of creatine supplementation on sprint exercise performance and muscle metabolism.
The aim of the present study was to examine the effect of creatine supplementation (CrS) on sprint exercise performance and skeletal muscle anaerobic metabolism during and after sprint exercise. Eight active, untrained men performed a 20-s maximal sprint on an air-braked cycle ergometer after 5 days of CrS [30 g creatine (Cr) + 30 g dextrose per day] or placebo (30 g dextrose per day). The tria...
متن کاملeffect of creatine supplementation on sprint and skill performance in young soccer players
the aim of this study was to determine the effect of creatine supplementation on sprint and skill performance in young soccer players. seventeen young soccer players (mean age: 17.18 ± 1.37 y, mean high: 169.6 ± 6.17 cm and mean weight: 61.67 ± 1.37 kg) participated in this study. subjects were assigned to either a creatine (5 g of cr, 4 times per day for 7 days) or a placebo group (same dosage...
متن کاملEffects of creatine supplementation on muscle power, endurance, and sprint performance.
PURPOSE To determine the effects of creatine (Cr) supplementation (20 g x d(-1) during 5 d) on maximal strength, muscle power production during repetitive high-power-output exercise bouts (MRPB), repeated running sprints, and endurance in handball players. METHODS Nineteen trained male handball players were randomly assigned in a double-blind fashion to either creatine (N = 9) or placebo (N =...
متن کاملEffects of creatine loading and prolonged creatine supplementation on body composition, fuel selection, sprint and endurance performance in humans.
Most research on creatine has focused on short-term creatine loading and its effect on high-intensity performance capacity. Some studies have investigated the effect of prolonged creatine use during strength training. However, studies on the effects of prolonged creatine supplementation are lacking. In the present study, we have assessed the effects of both creatine loading and prolonged supple...
