The aim of this study was to determine the reproducibility of an instrument of measurement of muscular power (MP), the Power Control Technogym@, through a simple test of MP. Fifteen women (26.2 ± 1.9 years) experienced in strength training in two exercises - the low row and the front lat pull down, were evaluated through a test of 1RM. The maximum load and the load that generated the MP in each exercise were determined. After obtaining the load that generated the MP, the individuals carried out three days of testing with the purpose to analyze inter and intradays reproducibility of the generated power. The comparison between the results of the MP was made through the ANOVA for repeated measures and Bonferroni post-hoc to specify which measures differ from each other, being adopted a level of significance of 5%. No significant differences were found at inter and intradays measurements respectively in the low row (p = 0.991; p = 1.000) and front lat pull down (p = 0.607; p = 1.000). This data can suggest that, for a simple test of MP, the Power Control TechnoGym@ seems to be a useful and trustworthy instrument in the use of loads in the MP.
