“…mentioned mechanisms also occur in these patients. In fact, we previously observed no changes in cardiac autonomic modulation [2] and increased blood flow [22] after a single REx bout in PAD patients, suggesting a peripheral role. Thus our hypothesis was that post REx hypotension is due to reduced vascular resistance subsequent to improved blood flow and reduced arterial stiffness.…”

This study aimed to analyze the vascular mechanisms involved in post-resistance decreases in blood pressure in patients with peripheral artery disease. 17 patients underwent 2 experimental sessions conducted in random order: resistance exercise (REx-3×10 reps in 8 exercises with intensity of ~ 60% of 1 RM) and control (C- resting on the exercise machines for 50 min). Before and after each experimental session, blood pressure, reflected wave indicators, pulse wave velocity, blood flow, blood flow post-reactive hyperemia and peripheral vascular resistance responses were obtained. Both sessions increased brachial systolic, diastolic and mean blood pressure (greatest increase REx: 11 mmHg; greatest increase C: 19 mmHg; P<0.01); however, the increases were greater after the C session (P<0.01). Reflected wave indicators increased only after the C session (P<0.06), while pulse wave velocity increased similarly after both sessions (P=0.66). Individual analyses indicated a large variability between patients in vascular variables responses. A single bout of REx decreased blood pressure in peripheral artery disease patients, and these responses were followed by changes in reflected wave indicators. The other factors presented high individual variability, and thus it was not possible to identify specific factors associated with blood pressure reduction in peripheral artery disease patients.

“…Evaluating the aerobic fitness and HRV in obese adults, physical activity was positive, suggesting that physical exercise throughout life can be important for preventing diseases associated with obesity. With this, the resistance exercise has an effect on the life of patients with peripheral artery disease, improving the ability to walk, quality of life and muscular strength 17,18 . Therefore, exercise has a positive role in stimulating the improvement of the physical capacity, presenting a significant and positive relation in the quality of life 2 .…”

Influência Da Atividade Física Na Modulação Autonômica Cardíaca

et al. 2018

A variabilidade da frequência cardíaca (VFC) é um método simples, não invasivo que consiste na oscilação dos intervalos entre os batimentos cardíacos consecutivos (R-R), sendo também um indicador funcional do sistema nervoso autônomo (SNA). O exercício físico estimula a aptidão cardiorrespiratória, concomitante a isto, provoca alterações na função autonômica cardíaca, além de ter impacto positivo na saúde por diminuir fatores de risco na manifestação das doenças cardiovasculares. Objetivou-se identificar dados através de uma revisão integrativa da literatura sobre a influência da prática de atividade física na modulação autonômica cardíaca. A estratégia de busca foi delineada no diretório de revistas da SciELO e nas bases de dados MEDLINE e LILACS. Foram selecionados os artigos que estivessem sido publicados nos últimos cinco anos (2013 a 2017). O operador booleano AND foi utilizado para a associação dos seguintes descritores: Sistema Nervoso Autônomo; Frequência Cardíaca; Atividade física; Sistema Nervoso Simpático; Sistema Nervoso Parassimpático. Empregados os descritores mencionados, apareceram 310 artigos que faziam referência à associação dos termos procurados. Dentre estes, permaneceram 39 estudos que foram impressos para a leitura íntegra. Destes, 22 estudos foram excluídos, pois não faziam referência ao tema central da pesquisa, restando 17 artigos. Os estudos selecionados indicaram que a modulação autonômica cardíaca frente a pratica de atividade física gera uma boa aptidão física que resulta em um aumento da VFC e um menor risco de desenvolver doenças cardíacas. Com algumas semanas da prática de atividade física, há um melhor balanço simpático-vagal onde há maior ativação da condução simpática após o início do exercício físico; pós-exercício há um aumento da condução parassimpática, além do que a aptidão e resistência física que se ganha com o exercício g era maior recuperação da frequência cardíaca após o exercício. A atividade física tem um impacto positivo no controle autonômico cardíaco quando é analisada por meio dos índices da VFC, nas diversas modalidades de exercício físico.

“…To analyze the HRV in the frequency domain, the low frequency (LF = 0.04 to 0.15 Hz) and high frequency (HF = 0.15 to 0.40 Hz) spectral components were used in ms 2 and normalized units, which represent a value relative to each spectral component related to the total power minus the very low frequency (VLF) components; we also examined the ratio between these components (LF/HF). The spectral analysis was calculated with the Fast Fourier Transform algorithm ( 13 ).…”

OBJECTIVES:Flexible poles can provide rapid eccentric and concentric muscle contractions. Muscle vibration is associated with a "tonic vibration reflex” that is stimulated by a sequence of rapid muscle stretching, activation of the muscle spindles and stimulation of a response that is similar to the myotatic reflex. Literature studies analyzing the acute cardiovascular responses to different exercises performed with this instrument are lacking. We investigated the acute effects of exercise with flexible poles on the heart period in healthy men.METHOD:The study was performed on ten young adult males between 18 and 25 years old. We evaluated the heart rate variability in the time and frequency domains. The subjects remained at rest for 10 min. After the rest period, the volunteers performed the exercises with the flexible poles. Immediately after the exercise protocol, the volunteers remained seated at rest for 30 min and their heart rate variability was analyzed.RESULTS:The pNN50 was reduced at 5-10 and 15-20 min after exercise compared to 25-30 min after exercise (p = 0.0019), the SDNN was increased at 25-30 min after exercise compared to at rest and 0-10 min after exercise (p = 0.0073) and the RMSSD was increased at 25-30 min after exercise compared to 5-15 min after exercise (p = 0.0043). The LF in absolute units was increased at 25-30 min after exercise compared to 5-20 min after exercise (p = 0.0184).CONCLUSION:A single bout of exercise with a flexible pole reduced the heart rate variability and parasympathetic recovery was observed approximately 30 min after exercise.
