Variabilidade da frequência cardíaca como recurso em fisioterapia: análise de periódicos nacionais

INTRODUCTION: The autonomic nervous system (ANS) could be investigated in a noninvasive way by the heart rate variability analysis (HRV) which has contributed to several health areas such as physiotherapy. OBJECTIVE: To gather information regarding the use of HRV on physiotherapy aims at providing an update of the findings for the area on journals of national circulation. MATERIALS AND METHODS: The journals of national circulation classified as greater than B2 or B2 and with free access and complete texts in some internet sites were searched on 21 area WebQualis resulting on selection of Revista Brasileira de Fisioterapia, Fisioterapia e Pesquisa and Fisioterapia em Movimento using the keywords: autonomic nervous system, sympathetic nervous system, physiotherapy and heart rate variability. RESULTS: The search resulted in 19 articles being 17 clinical trials and two case reports. CONCLUSION: The HRV has been used as a resource of interventions evaluation, as pathological conditions common to clinical practice investigation and to physiological conditions interpretation in physiotherapy. The HRV is principally used to the cardiorespiratory specialty of physiotherapy.

Influência do exercício resistido aplicado de forma aguda sobre a variabilidade da frequência cardíaca em jovens ativos saudáveis: análise por meio de índices geométricos

Introduction: The triangular index and the Poincaré plot (or Lorenz plot) are the best known indexes obtained from geometric methods. The triangular index (TINN, RRtri) represent the global variability of the subject and SD1, which reflects the parasympathetic component, SD2, index of global variability and its relationship (SD1/SD2) are obtained from the Poincaré plot. Despite the literature showing changes in the cardiovascular system during and after the resistance exercise (RE), aspects related to autonomic modulation of heart against these conditions have not been explored yet, so it is important to evaluate this behavior. Objectives: Analyze the acute effects of RE on the cardiac autonomic modulation during recovery (REC) through analysis of geometric indices of heart rate variability (HRV), applied with different intensities and muscle groups in healthy and active young. Methods: Were evaluated 24 young, 22.25 ± 2.4 years and 24.47 ± 3.08 kg/m2, underwent an experimental protocol of five stages, in the first stage was conducted a test of one maximum repetition (1RM) in upper limbs (UL) and lower limb (LL), and the following steps were initiated interventions to 40 (E) and 80% (F) of 1RM. Considered for HRV analysis the periods: baseline and immediately after exercise, both in supine... (Complete abstract click electronic access below)

Acute effects of flexible pole exercise on heart rate dynamics

Introduction: Exercise with flexible poles provides fast eccentric and concentric muscle contractions. Although the literature reports significant muscle chain activity during this exercise, it is not clear if a single bout of exercise induces cardiac changes. In this study we assessed the acute effects of flexible pole exercise on cardiac autonomic regulation.Methods: The study was performed on 22 women between 18 and 26 years old. We assessed heart rate variability (HRV) in the time (SDNN, RMSSD and pNN50) and frequency (HF, LF and LF/HF ratio) domains and geometric indices of HRV (RRTri, TINN, SD1, SD2 and SD1/SD2 ratio). The subjects remained at rest for 10 min and then performed the exercises with the flexible poles. Immediately after the exercise protocol, the volunteers remained seated at rest for 60 min and HRV was analyzed.Results: We observed no significant changes in time domain (SDNN: p=0.72; RMSSD: p=0.94 and pNN50: p=0.92) or frequency domain indices (LF [nu]: p=0.98; LF [ms(2)]: p=0.72; HF [nu]: p=0.98; HF [ms(2)]: p=0.82 and LF/HF ratio: p=0.7) or in geometric indices (RRTri: p=0.54; TINN: p=0.77; SD1 p=0.94; SD2: p=0.67 and SD/SD2: p=0.42) before and after a single bout of flexible pole exercise.Conclusion: A single bout of flexible pole exercise did not induce significant changes in cardiac autonomic regulation in healthy women.
