Efeitos de diferentes doses de suplementação de creatina sobre a composição corporal e força máxima dinâmica

Abstract

The aim of this study was to compare the effects of creatine supplementation and periodized strength training on body composition, and maximal dynamic strength during 8 weeks. 27 men were selected, divided into three groups: placebo, creatine loading supplementation and low-dose creatine supplementation groups. The training was composed by three weekly sessions. Body mass (kg), fat-free mass (kg), fat mass (kg) body fat percentage (%), and maximal dynamic strength in bench press, squat, lat pulldown, leg curl, barbell arm curl, seated calf raises, military press, and triceps pulley were measured. There was an percentage increases in body mass and lean body mass for all groups, but no difference between groups. Significant increase in maximal strength in back lat pull down, arm curl and triceps pushdown was observed, without differences between groups. These data suggest the both modes of creatine supplementation associated with strength training promote positive adaptations in body composition and maximal dynamic strength.
