“…Contrastingly, the healthy control group was affected markedly by the physical exercise test over every HRV parameter; a reduction in both the time-domain parameters as well as HRV is observed during submaximal exercise testing in both women and men and gradually returns to resting values during recovery [28,29]. In young, healthy subjects HRV remains affected 15-25 minutes after both submaximal exercise tests and resistance training.…”

Objective: To compare the heart rate variability (HRV) before and after a sub-maximal exercise test in women with fibromyalgia (FM) and to compare the result to matched controls. Additionally, to compare heart rate (HR) before, during and after the sub-maximal exercise test.Methods: Twenty-four women with FM and 26 controls performed a sub-maximal exercise test. HRV was registered for 5 minutes at rest before and after the exercise test. HR was registered at baseline, during the exercise test and at recovery. Results:The HRV of the healthy group was statistically different from the exercise test but the women with FM showed no such difference. HR was significantly higher among the women with FM than in the healthy group at baseline and up to 75W but lower at peak (138/152 bpm, p<0.008). In women with FM HR during exercise (HR2) was predicted by heart rate recovery (HRR20) and physical exertion (RPE2). HRR20 and RPE2 accounted for 0.465 of the variance (p=0.006) in HR2. In healthy women HR2 correlated with HRR20 and negatively with physical activity (PhA). In the reference group HRR20 and PhA accounted for 0.448 (p=0.002) of the variance HR. Conclusion:The HRV in women with FM show less adjustment of the ANS while not being significantly affected by submaximal exercise as healthy women. In healthy women heart rate during the test was negatively related to PhA. In women with FM exertion seems to replace an effect from exercise on physiological adaptation. FM may entail imperceptible extraction of power from PhA while under load. Links to FM pain will be discussed.Women with FM seem to rate exertion "Very hard" on lower workload and HR than healthy women. The physiotherapeutic methodology for measuring HRV with basic HR monitors should be improved before it can be recommended for clinical use.

“…Participants were predominantly males who were aged, on average, 59 years and taking beta-blockers. However, there are studies that show that HRV results during exercise are independent of age and sex [34]. Previous studies that evaluated the reproducibility between Polar and Holter in the analysis of HRV in healthy subjects showed overall good intra-class correlation but unsatisfactory results in women [14] in frequency-domain variables [15] and rMSSD [11].…”

Heart rate variability (HRV) analysis is a useful method to assess abnormal functioning in the autonomic nervous system and to predict cardiac events in patients with heart failure (HF). HRV measurements with heart rate monitors have been validated with an electrocardiograph in healthy subjects but not in patients with HF. We explored the reproducibility of HRV in two consecutive six-minute walk tests (6MW), 60-minute apart, using a heart rate monitor (PolarS810i) and a portable electrocardiograph (called Holter) in 50 HF patients (mean age 59 years, NYHA II, left ventricular ejection fraction ~35%). The reproducibility for each device was analysed using a paired t-test or the Wilcoxon signed-rank test. Additionally, we assessed the agreement between the two devices based on the HRV indices at rest, during the 6MW and during recovery using concordance correlation coefficients (CCC), 95% confidence intervals and Bland-Altman plots. The test-retest for the HRV analyses was reproducible using Holter and PolarS810i at rest but not during recovery. In the second 6MW, patients showed significant increases in rMSSD and walking distance. The PolarS810i measurements had remarkably high concordance correlation [0.86

“…In addition to simple and reproducible, TC6 becomes safe by the self-limitation capacity of the individuals themselves during their execution. TC6 has a higher correlation with the demands of daily activities when compared to the ergometer cycle, besides presenting also relationship with other variables of physical capacity before the effort 18 becoming an alternative for the evaluation of tolerance and physiological behavior before physical exercise.…”

“…TC6 was carried out in a 20-meter corrido, marked and free of traffic from other people. For its implementation, the patient was asked to walk from one extreme to the other part of the corridor for six minutes, with the largest walking speed that he could 18 . The variables were collected at the beginning and end of the test.…”

Heart rate variability (HRV) analysis is an important method to evaluate the modulation of autonomic nervous system on cardiac activity. The goal was to evaluate the heart rate variability behavior in hypertensive middle-aged men at rest, before and after submaximal physical test. It is a cross-sectional, analytical study with sedentary men, middle-aged (mean 48 years) and owners of clinical diagnosis of hypertension who underwent to a physical therapy evaluation, and obtainment of HRV at rest in the supine position, sitting position and before a 6-minute walk test and after it. The values of HRV indexes on time and frequency domain showed low and statistically significant (p<0.05) when analyzed and compared at rest and after the execution of the test. Conclusion: The data suggest that the studied hypertensive volunteers showed a reduction of HRV immediately after the 6-minute walk test, implying a reduction in parasympathetic modulation during this period and the consequent increase in cardiovascular risk after physical exertion, even being a submaximal test.Keywords: Physical Exertion Heart. Hypertension. Autonomic Nervous System.ResumoA análise da variabilidade da frequência cardíaca (VFC) é um importante mecanismo para a avaliação da modulação do sistema nervoso autônomo sobre a atividade cardíaca. O objetivo do estudo foi avaliar o comportamento da variabilidade da frequência cardíaca de homens de meia-idade e hipertensos na condição de repouso antes e após serem submetidos a esforço físico submáximo. Trata-se de um estudo analítico transversal, em que foram estudados homens, sedentários de meia idade (média de 48 anos) e possuidores de diagnóstico clínico de hipertensão arterial sistêmica, submetidos à avaliação fisioterapêutica e captação da VFC na condição de repouso em supino, sedestação e antes de realizar teste de caminhada de 6 minutos (TC6) e após sua execução. Os valores dos índices de VFC nos domínios de tempo e frequência estudados apresentaram-se reduzidos e estatisticamente significantes (p<0.05) quando analisados e comparados em repouso e após a execução do teste. Os dados sugerem que os hipertensos estudados apresentaram uma redução da VFC imediatamente após o TC6, inferindo uma diminuição da modulação parassimpática neste período e consequente aumento no risco cardiovascular após o esforço físico, ainda que submáximo.Palavras-chave: Esforço Físico.
