Abstract

Creatine supplementing has been widely used to improve muscle performance and increase creatine-phosphate storages in skeletal muscle amongst people practicing strength developing training. The objective of the present study was verifying in a period of 15 days whether oral supplementation of monohydrated creatine provides ergogenic effect on performance during concurrent exercises between endurance training and strength training. Material and Methods: The sample for this study was formed by eleven gymnasium members randomly divided in two groups: supplemented group (GS) and placebo group (GP).The supplementation was conducted using the double blind experimentation method, 20g/day of placebo powder for the placebo group (GP) and the same quantity of monohydrated creatine for the supplemented group (GS) during five days followed by 5g/day for ten days in a total of 15 days of supplementation. Prior to the supplementation all members were submitted to 1-RM test and test of maximum repetitions on the forward pulley conducted at 70% of the value obtained from the 1-RM test subsequent to the endurance training (45 minutes swim). Results: After the swimming test there was no significant differences in the number of maximum repetitions at 70% of 1-RM for the placebo group: In contrast to the placebo group, the group supplemented with monohydrated creatine displayed an increase in the number of maximum repetitions at 70% of 1-RM. Conclusion: This study shows that creatine supplementation improves strength performance in concurrent exercises and potentially.
