ABSTRACT Objective To investigate whether acute citrulline supplementation might influence post-exercise hypotension in normotensive and hypertensive individuals. Methods Following a randomized double-blind design, twenty normotensive (28±7 years, 74±17kg, 1.7±0.09m) and 20 hypertensive individuals (55±12 years, 76±15kg, 1.59±0.09m) were randomly assigned to one of the four experimental groups (Normotensive-Placebo; Normotensive-Citrulline; Hypertensive-Placebo; Hypertensive-Citrulline). The placebo groups ingested 6g of corn starch and the citrulline groups ingested 6g of citrulline dissolved in water. The participants performed 40 minutes of walking/running on a treadmill at 60-70% heart rate reserve. Blood pressure was measured immediately after a 60-min exercise session using an oscillometric device and 24-h ambulatory monitoring. Results The post-exercise hypotension was more pronounced in hypertensives and the Hypertensive-Citrulline group showed a consistent systolic blood pressure reduction during the laboratorial phase, which can be seen by looking at the mean of 60 minutes (-15.01mmHg vs -3.14mmHg [P=0.005]; -4.16mmHg [P=0.009]; -6.30mmHg [P=0.033] in comparison with the Normotensive-Placebo, Normotensive-Citrulline, and Hypertensive-Placebo groups, respectively). During ambulatory blood pressure monitoring, the Hypertensive-Citrulline group showed a significant reduction in systolic blood pressure (-21.05mmHg) in the awake period compared with the Normotensive-Citrulline group (-3.17mmHg [P=0.010]). Conclusion Acute citrulline oral supplementation can induce greater post-exercise hypotension response in hypertensive than normotensive individuals.

ABSTRACTObjective: to observe, through a literature review, the effects of counter-resistance exercise on hypotension post-exercise. Methods: this is a review study, based on national and international literature, that was considered the inclusion of articles in order to determine the cardiovascular responses in patients, with the use of resistance exercises, which used non-invasive methods of measurement of blood pressure. Studies that showed no recovery time after exercise as well as research involving other types of combined exercise except resistance exercise were excluded. Results: among the eleven studies involving hemodynamic responses and resistance exercise, four were evaluated considering the criteria for exclusion. Two studies showed a decrease in BP after a resistance exercise session for both systolic blood pressure and for diastolic blood pressure. One study that was found only for systolic blood pressure, and another just for the diastolic. Final comments: although it is not yet a consensus about the prescription of exercise for post-exercise hypotension, resistance exercise greater volume impacting more positively in blood pressure after activity, and this result may be more easily found through the systematic and continued practice of resistance exercise (physical training), and not simply an acute form. Descriptors: hypertension; post-exercise hypotension; resistance exercise.  RESUMOObjetivo: observar, por meio de uma revisão de literatura, os efeitos do exercício contra-resistência, na hipotensão pós-exercício. Métodos: estudo de revisão, nacional e internacional, considerando-se a inclusão de artigos com o objetivo de verificar as respostas cardiovasculares em hipertensos, com o uso de exercícios resistidos, por meio de métodos não-invasivos de mensuração da tensão arterial. Foram excluídos aqueles que não apresentavam tempo de recuperação após o exercício e pesquisas envolvendo outro tipo de exercício combinado que não o resistido exclusivamente. Resultados: dos onze estudos envolvendo respostas hemodinâmicas e exercício contra-resistência, quatro foram avaliados. Dois mostraram diminuição da PA após uma sessão de exercício resistido, tanto para a pressão arterial sistólica como para a diastólica. Um estudo que encontrou hipotensão apenas para a sistólica, e o outro para a diastólica. Considerações finais: apesar de ainda não ser consenso a forma como deve ser conduzido a prescrição de exercícios contra-resistência para obter hipotensão pós-exercício, exercícios resistidos de maior volume possam repercutir de forma mais positiva na pressão arterial após atividade, e talvez esse resultado seja mais encontrado por meio da sistematização e continuidade da prática de exercícios resistidos (treinamento físico), e não simplesmente de forma aguda. Descritores: hipertensão; hipotensão pós-exercício; exercício resistido.  RESUMEN Objetivo: observar, a través de una revisión, los efectos del ejercicio de resistencia a la hipotensión pos-ejercicio. Métodos: este stúdio se basa en la literatura nacional e internacional, considerando la inclusión de los artículos a fin de determinar las respuestas cardiovasculares, con el uso de ejercicios de resistencia, que utiliza métodos no invasivos de la medición de la presión arterial. Se excluyeron de la evaluación, los estudios no han mostrado el tiempo de recuperación después del ejercicio y la investigación con otros tipos de ejercicios combinados que no se resistió. Resultados: de los once estudios con las respuestas hemodinámicas y el ejercicio de resistencia, cuatro fueron evaluadas teniendo en cuenta los criterios de exclusión. Dos estudios mostraron una reducción de la PA después de un período de ejercicio de resistencia, tanto para la presión arterial sistólica y diastólica. Un estudio encontró que la presión arterial sólo para la sistólica y la otra sólo para la presión. Consideraciones finales: a pesar de que no es un consenso sobre cómo debe llevarse a cabo el ejercicio de resistencia para a la hipotensión pos –ejercicio, ejercicio de fuerza mayor volumen que afectan de forma más positiva de la presión arterial después de la actividad, y este resultado puede ser más fácil de encontrar a través de la práctica sistemática y continua de los ejercicios de resistencia (entrenamiento físico), y no una forma aguda. Descriptores: hipertensión; hipotensión pos-ejercicio; ejercicio contra la resistencia.

Abstract Objective: The aim of the present study was to verify the behavior of hemodynamic variables in hypertensive older women following a combined exercise session and to identify the intensity of effort achieved in this session. Method: The study included 14 hypertensive older women (72.0±6.7 years old) who regularly practiced physical activities. The participants underwent a one-hour combined exercise session performed in a group, with intensity of effort monitored by accelerometry (Actigraph, model GT3X+). The hemodynamic parameters (systolic blood pressure, diastolic blood pressure, heart rate, stroke volume, cardiac output and peripheral vascular resistance) were individually measured by finger photoplethysmography (Finometer) before and after (60 min) the exercise session. Results: The sessions consisted predominantly of low-light intensity activities (60%) and 20% of class time was spent on sedentary behavior. None of the evaluated variables exhibited changes when the pre and post-exercise values were compared (p>0.05). Systolic blood pressure behavior correlated positively with time spent in sedentary behavior (r=0.541; p=0.045). Conclusion: The combined exercise sessions, as conducted, did not generate post-exercise hypotension. In addition, the time spent in typically sedentary activities during the classes positively correlated with changes in blood pressure, suggesting that combined exercise programs, applied in the form of collective aerobic exercises, should be composed of higher intensity activities.

The purposes of this study were to analyze and compare the effects of exercise performed in different intensities, above and below lactate threshold (LT) on post-exercise blood pressure (BP) and nitric oxide (NO) responses in individuals with type 2 diabetes (T2D). For this, 11 T2D underwent the following sessions: 1) control session; 2) 20-min of moderate cycling (80% LT); and 3) 20-min of high intensity cycling (120%LT) on a cycle ergometer. Plasma NO and BP measurements were carried out at rest and at 15 and 45 min of post-sessions. When compared to rest, only the exercise session performed at 120%LT elicited an increase of NO (from 7.2 to 9.5 µM, p<0.05), as well as a decrease in systolic BP (from 126.6±7.9 to 118.7±3.9 mmHg, p<0.05) during the post-exercise period. In conclusion, the results suggest that NO release and post-exercise BP decrease are intensity-dependent for individuals with T2D.

ABSTRACT Introduction: Powerlifting (PWL) is a worldwide method, frequently used in resistance training programs. However, the relationship between cardiovascular responses and PWL is still unclear in the literature. Objective: To evaluate acute cardiovascular overload and post-exercise hypotension (PEH) after acute powerlifting exercise session in subjects with experience in the modality. Methods: Nine powerlifting athletes (34 ± 5 years) participated voluntarily in this study. The following exercises were used in the session: squat, bench press and deadlift (95% of 1 RM, 2 to 5 repetitions). The anthropometric parameters and blood pressure (systolic, diastolic and mean) were evaluated immediately, 5', 10', 30', 60' and 24 hours after the exercise session with a non-invasive automatic pressure monitor. Results: Significant differences (p<0.05) were found between rest and immediately after exercise on systolic (135 ± 6 vs. 153 ± 10 mmHg) and mean (102 ± 3 vs. 108 ± 3 mmHg) blood pressures, but no difference was found at diastolic (85 ± 3 vs. 85 ± 4 mmHg) blood pressure. Additionally, the increase in systolic pressure did not reach values considered as a risk of cardiovascular overload. Significant PEH was found after 60 minutes (systolic: -12 ± 12%, diastolic: -5 ± 6% and mean: -7 ± 5%) and 24 hours after PWL session (systolic: -5 ± 4%, diastolic: -8 ± 4% and mean: -7 ± 3%). Conclusion: Our data demonstrated that a PWL session does not increase systolic blood pressure up to the risk range and promotes PEH after 60 minutes of exercise and that this cardiovascular response persisted after 24 hours post-exertion in powerlifting athletes.

INTRODUCTION: After a single session of physical exercise the blood pressure is reduced (post-exercise hypotension, PHE) and it has been considered as a non-pharmacological mechanism to control the blood pressure. When the exercise is performed since youth it can prevent or avoid hypertension. However, it is important to consider studies with clear practical applications to optimize its reproducibility on a daily basis. OBJECTIVE: Analyze the PEH of normotensive and physically active young men after two track running sessions (maximum and submaximal). METHODS: Participated in this study 62 physically active young men (23.3 ± 4.2 years old; 75.5 ± 9.8 kg; 177.7 ± 5.5 cm; 12.0 ± 4.6% body fatF; 52.4 ± 4.0 mL.kg-1.min-1oxygen uptake), which performed a maximum laboratory exercise test for determination of maximal oxygen uptake (VO2max - aerobic power) and subsequently three randomly running sessions (maximum - T1600; submaximal - T20; control - CON), with 48h interval between themselves. Blood pressure (BP) was measured each 15min during a 60 min period after sessions. RESULTS: Both the maximum and the submaximal exercise lead to PEH. The post-exercise values of systolic blood pressure and diastolic blood pressure differed from resting value in session T20 (p<0.05). The same pattern occurred after T1600 (p<0.05), evidenced from 30th minute post-exercise. The CON did not result in PEH. The magnitude of decay for the mean BP at the 45th after maximum exercise was higher than the other sessions (p<0.05). CONCLUSION: We concluded that both maximum and submaximal exercises, performed on a track running condition, caused PEH in young normotensive and physically active men.
