Introduction: Neuromuscular Electrostimulation is a technique of involuntary contraction of skeletal muscles.. Since overlapping voluntary contraction in strength training may potentiate the physiological effects resulting from training, therefore, these adaptations are not yet fully elucidated in the literature. Objective: The aim of the study was to verify the influence of neuromuscular electrical stimulation concomitant with strength training on blood lactate levels. Method: Twenty male individuals aged between 20 and 30 years participated in the study. All subjects participated in 3 training protocols at random, namely, extension chair (EC), electrostimulation (EE) and overlapping chair with electrostimulation (EC + EE) all subjects participated in all protocols at random. Lactate was measured via venous blood and analyzed by spectrophotometry. Statistical data were obtained with the aid of SPSS 19.0. Results: All training protocols induced a significant increase in blood lactate levels when compared to rest (p≤0.05), but when comparing the methods, the EC + EE protocol ( 5.9mmol / L) compared to EC (5.6mmol / L) showed no statistically significant difference (p = 0.433). Conclusion: Electrostimulation induces an increase in lactate levels, but when combined with strength training protocols this increase does not occur significantly.
