Abstract
Introduction: There has been an increasing awareness of the need to practice some physical activity with several objectives, mainly as a preventive character. From this perspective, it's possible to notice the use of Pilates method as an instrument of therapeutic exercise for the protection and promotion of health. Despite being popularly performed, there is still no scientific evidence on the standardization of the method usage and its progression to an adequate prescription of physical training. Objective: In order to monitor the progression of loads of a 12-week training among the basic, intermediate and advanced levels of the Pilates method through heart rate (HR), subjective exertion perception (PSE) and heart rate variability (HRV), including the effect of the method on cardiorespiratory and autonomic parameters analysis. Methods: 32 healthy men aged 18-36 years will be divided into two groups: the pilates group (n = 16) and the control group (n = 16). The pilates group will receive Pilates training for 12 weeks while the control group will not receive any type of intervention. After the initial evaluation and familiarization with the method, the training period will begin, totaling 36 sessions for three months lasting approximately 1 hour each class. During the three months, the participants must pass through the three levels of training: basic, Intermediate and Advanced. During each session, a psychological questionnaire, visual analog pain scale (VAS), and cardiorespiratory parameters (systolic and diastolic blood pressure, HR, respiratory rate and partial oxygen saturation) will be collected before the training itself. Throughout the session a heart rate meter will be positioned in the chest of the participant to capture the HR that will occur every five minutes with the PSE illustrated in the model proposed by Borg. At the end of each session, the cardiorespiratory parameters will be collected again. In addition, cardiorespiratory parameters and HRV will be analyzed at baseline and after three months of training. For HRV analysis, linear methods in the time and frequency domain will be verified. For the statistical analysis of the cardiorespiratory and autonomic parameters in the pre and post training moments will be used paired t test for normal data or Wilcoxon test for non normal data. For the analysis of the training load will be used the correlation of Pearson or Sperman according to normality. The definition of cutoff points for the HRV and PSE indices will be obtained by the ROC curve. (AU)
