Vision can make powerful contributions to the controlof movement, but its influence is not always positive. For this reason, many performers choose other forms of control, such as the visual dominance, which is the tendency of visual information to dominate the information from other senses during perception. In this context, the aimof this study was to evaluate strength in the bench press exercise with and without visual feedback. The sample consisted of 20 subjects, 10 men (age = 24.5 ± 1.1 years, weight = 75.4 ± 1.1 kg, height = 174.4 ± 1.03 cm, BMI = 25.23 ±, 508 kg/m²) and 10 women (age = 24.9 ± 1.3 years, weight = 61.7 ± 1.7 kg, height = 168.1 ± 1.74 cm, BMI = 21.8 ±, 462 kg/m²), healthy, practicing strength training for more than twelve months. Familiarization was made and after 72h performed the tests of 1 repetition maximum (1RM) in the bench press exercise with and without visual feedback ( the reliability index found was r=0.98). There was a significant increase in muscle strength (approximately 4%) for 1RM test with deprivation of vision comparing to testing without deprivation, for both men and women no gender difference. This study suggests that deprivation of vision, so individuals can’t underestimate themselves with the load, can increase test performance of 1RM.
