Cardiovascular variables, such as heart rate (HR) and blood pressure (BP), are controlled by autonomous nervous system and has been related to gun-shooting performance. Transcranial direct current stimulation (tDCS) has shown to be able to increase parasympathetic activity and decrease sympathetic activity. Therefore, tDCS might be able to improve gun-shooting performance since it can changes autonomous nervous activity and decrease HR and BP. Purpose: Analyze the effect of tDCS on shooting performance and cardiovascular responses. Methods: Thirteen male military cops from different centers composed the sample (33±4 anos; 172.4±5.4 cm; 79.5±7.2 kg; 26.7±1.4 kg/m²). In a first step of the study, subjects underwent into two shooting familiarization sessions, and shooting performance was assessed in order to classify subject accordingly with their performance. In the second phase of the study, subjects were randomly assigned to 3 sessions with different tDCS conditions: single lateral anodal tDCS (tDCS-A), bilateral anodal tDCS (tDCS-B), and a sham tDCS (tDCS-S). Before and after tDCS heart rate (HR), heart rate variability (HRV), blood pressure (BP), shooting accuracy, precision, score, and time were assessed. Results: A two-way ANOVA showed no effect of any tDCS condition on any of cardiovascular measures and shooting performance (accuracy, precision, score, and time). Conclusions: We conclude that tDCS has no effect on cardiovascular variables and, consequently, no effect on shooting performance in military cops.Acesso AbertoTiroNeuromodulaçãoFrequência cardíacaVariabilidade da frequência cardíacamasterThesisCNPQ::CIENCIAS DA SAUDE::EDUCACAO FISICA
