Twenty-two participants were randomized to supplement with creatine (CR: n = 13, 26.15 ± 4.66 yrs, 80.5 ± 18.07 kg, 174.50 ± 10.53 cm; 0.0055 g/kg post training set) or placebo (PLA: n = 9, 26.44 ± 5.10 yrs, 79.88 ± 19.97 kg, 175.05 ± 12.09 cm; 0.0055 g/kg post training set) during 6 weeks of resistance training (18 sets per training session). Prior to and following training and supplementation, measurements were made for muscle thickness (elbow and knee flexors and extensors, ankle plantarflexors; ultrasound), muscular power (vertical jump, medicine ball throw), muscular strength (leg press and chest press 1-repetition maximum [1-RM]) and muscular endurance (1 sets of repetitions to volitional fatigue using 50% baseline 1-RM for leg press and chest press). There were group x time interactions for leg press and chest press strength and leg press and total body endurance. The creatine group experienced a significant increase in leg press (pre 188.06 ± 88.68 kg, post 231.68 ± 89.39 kg; p < 0.001) and chest press strength over time (pre 120.89 ± 54.87 kg, post 143.38 ± 66.04 kg; p = 0.001) with no significant changes in the placebo group (leg press strength: pre 188.80 ± 107.96 kg, post 201.68 ± 89.39 kg, p = 0.106; chest press strength: pre 143.38 ± 65.10 kg, post 143.38 ± 66.04 kg; p = 1.000). Creatine supplementation also improved leg press endurance (pre 17.53 ± 8.96 reps, post 30.00 ± 9.38 reps; p < 0.001) and total body endurance (leg press and chest press combined) (pre 40.30 ± 10.52 reps, post 58.15 ± 13.56 reps; p < 0.001) more than placebo (leg press: pre 19.25 ± 9.63 reps, post 23.37 ± 12.27 reps, p =0.084; total body: pre 41.33 ± 13.39 reps, post 47.88 ± 16.09 reps, p = 0.044). In conclusion, creatine ingestion during resistance training sessions is a viable strategy for improving muscle strength and some indices of muscle endurance in physically active young adults.","abstract_html":"The purpose was to examine the effects of intra-workout creatine supplementation during resistance training sessions on muscle mass and exercise performance in physically active young adults.
