Effect of Global Postural Reeducation on cardiovascular system of healthy subjects

Abstract

Objective: To evaluate the effect of Global Postural Reeducation (GPR) on cardiovascular system by heart rate variability (HRV), blood pressure (BP) and heart rate (HR). Materials and methods: Seventeen healthy men (22.47 ± 3.02 years) were submitted to the postures frog on the floor, frog on the air, sitting, standing against the wall and inclined standing, two postures per session. The systolic and diastolic blood pressure (SBP and DBP) and HR were recorded. The intervals between heartbeats were collected during the whole session (Polar S810i). The frequency domain was analyzed (Wavelet Transform), the low frequency (LF) and high frequency (HF) were obtained. The data were analyzed by ANOVA and Tukey (p < 0.05). Results: Increased LF/HF ratio was observed in the frog on the floor (1 ± 0.1 vs. 2 ± 0.3 p < 0.05) and on the air postures (1 ± 0.1 vs. 2 ± 0.2 p < 0.01). There was an increase in SBP in the postures frog on the floor (123 ± 2 vs. 136 ± 4 p < 0.05), frog on the air (122 ± 2 vs. 133 ± 3 p < 0.05), standing against the wall (123 ± 2 vs. 136 ± 4 p < 0.05), inclined standing (124 ± 3 vs. 146 ± 5 p < 0.05). There was increase of DBP in the postures frog on the floor (69 ± 2 vs. 81 ± 2 p < 0.01), frog on the air (72 ± 2 vs. 83 ± 3 p < 0.05), sitting (85 ± 2 vs. 102 ± 3 p < 0.01). There was increase in HR in the postures frog on the air (67 ± 2 vs. 77 ± 3 p < 0.05) and inclined standing (88 ± 3.5 vs. 101 ± 3 p < 0.05). Conclusion: The increase in LF/HF ratio and also the BP and HR indicates high sympathetic activity, possibly related to the work isometric developed during GPR method. [P] Keywords: Posture.

Cardiac Autonomic Modulation Behavior in Community Men with Hypertension on rest and Effort Condition

“…The studies on the relationship between the sympathetic and parasympathetic nervous system and mortality due to cardiovascular disease encourage the investigation of quantitative markers of cardiac autonomic modulation, being the heart rate variability the most promising marker 10,26,27 . HC can be captured by different instruments, and the electrocardiogram despite still being widely used, has its application limited by the high cost, complexity by specific positioning of numerous electrodes in addition to demanding outpatient physical space.…”

Morphotypological Prevalence of Individuals Assessed by the Method of Global Postural Reeducation by Proprioceptive and Muscular Rebalancing (GPR/PMR)

“…This method has been used in the urinary incontinence treatment [29,30], as well as in the neurological field, in the cervical dystonia treatment [31], stroke [32], and Parkinson's disease [33,34], since its use may promote changes in the motor potential evoked spinal and supraspinal [10]. Finally, in the cardiopulmonary scope, pieces of evidence have been presented in the cardiovascular system response [35]; and in the chronic obstructive pulmonary disease treatment [36], since it has been observed an improvement in respiratory muscle strength and an increase in thoracic cavity mobility after the technique application [37].…”
