Heart Rate Variability and the Isostretching Method: Postural Re-education and the Heart

The study of heart rate variability (HRV) analysis in healthy young people undergoing the Isostretching method was chosen because it provoked curiosity due to the diversity of postures that make up the method, the voluntary effort and patient concentration required during treatment. According to Redondo (2006), the postures in this type of physical activity with therapeutic purposes in the treatment of postural imbalances cause mechanical and physiological effects on the tissues, but most studies focus on the mechanical effects. Therefore, the aim of this research is to analyze the physiological effects that these postures can produce by verifying the influence of Isostretching on the autonomic nervous system (ANS) through the analysis of HRV.
