Introduction: The squat is an exercise in closed kinetic chain, widely used in gyms and in patient rehabilitation plans with knee injuries, the vastus muscle has very important because it is a large medial patellar stabilizer. Electromyography, is present in several studies in health. Objective: The objective of this study was to determine whether there is a difference in activation of the vastus muscle in standard squat exercise at angles of 60 ° and 90 °. Material and Methods: A total of 8 males, mean age 23.50 ± 2.83, physically active. The evaluated ones were submitted to the 10RM test, they were heated and then they had three attempts to perfom the 10RM, with the load adjusted by the person responsible for the collection. They did the exercise in two angles, the 60 ° and 90 °. Data were expressed in the results and tables mean ± standard deviation. Descriptive statistics were used for data exposure. The normality of the data was verified by the Shapiro-Wilk test. The comparison was performed using the paired t test. All analyzes were performed using SPSS software version 21.0. It adopted p <0.05 significance level. Results: EMG activation was significantly higher (p = 0.004) in the squat 90 compared to 60. Final Thoughts: We conclude that activation of the vastus was higher at 90 ° angle to the 60 ° angle in standard squat exercise.
