Periodized Aerobic Interval Training in Metabolic Syndrome

Study Overview
=================
Brief Summary
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Periodized aerobic interval training<br>The experimental groups will participate in a 16 week, three times a week based-program of periodized aerobic interval training that consist in warming [5 minutes of general stretching and 5 minutes of walking on treadmill with heart rate less than 20 percent of heart rate reserve (HHR)], followed by periodized aerobic interval training on treadmill, and cooling down [5 minutes of walk in treadmill with a heart rate less than 20 percent of HRR and 5 minutes of rest] | Behavioral: Periodized aerobic interval training<br>* The periodized training program consist in 3 phases: light (I) (training range varying between 20 to 39% of heart rate reserve and active recuperation of 19% of heart rate reserve); moderate (II) (training range varying between 40 to 59% of heart rate reserve and active recuperation of 30% of heart rate reserve) and high (III) (training range varying between 70 to 90 % of heart rate reserve and active recuperation of 50% of heart rate reserve).<br>|
| No Intervention: Control group<br>Participants in the control group will be instructed not to take part in any regular exercise programs during the study period. | |
