Autonomic disfunction present in metabolic syndrome subjects is related by a greater vulnerability of the heart and risk of cardiovascular events. In this context, aerobic interval training has been highlighted by its easy applicability and benefits effects in autonomic modulation in different populations. Therefore the studies that use de aerobic interval training in this different populations didn't realize a periodization of training with preparatory periods with progressive increase of load, specific phases with less duration predominating the intensity and transition periods for recuperation. Additionally, there isn't studies that investigate the effects of aerobic interval training in autonomic modulation of individuals with metabolic syndrome. In this context, periodized aerobic interval training can arise like a new type of treatment that offering security and efficacy in subjects with metabolic syndrome. So, the aim of the study is evaluate the effect of periodized aerobic interval training in cardiac autonomic modulation and cardiovascular and anthropometric parameters of individuals with metabolic syndrome.
