Through sympathetic and parasympathetic autonomic responses, the Autonomic Nervous System (ANS) modifies the heart rate (HR) according to physiological need in different conditions, and promotes changes in resistance of the passage of blood flow in blood vessels. The heart rate variability (HRV), which relates the variations between consecutive heart contractions, or RR intervals, can be understood as a parameter that evaluates the neurocardíaca functionality because the SNA acts directly on the rhythm and cardiac pumping function. Changes in HRV could contribute to possible disturbances in the cardiac system. Faced with this question, different strategies are needed to improve it, in particular, stands out exercise physical. The concurrent training, name given to the training programs that add exercises aerobic and strength, causing the two distinct metabolic pathways interfere one over the other, have also been explored by some scholars in research on chronic cardiovascular autonomic adaptations, however, the evidence on the SNA front of behavior interference effect is unknown. Also, it is still inconsistent in the literature the real effect of isolated strength training in SNA, so it is essential to spread more studies on this protocol. Objective of this study is to analyze the effects of concurrent and strength on cardiac autonomic modulation of active individuals.
