Jiu-jitsu is a sport that involves different techniques to lead the opponent to submission, combats are characterized by intermittent efforts with changes in important cardiovascular variables. Thus, the aim was to evaluate the acute effects of a simulated jiu-jitsu match on blood pressure (BP) and the double product (DP) of fighters in the master category. The heart rate (HR), BP, and DP of six experienced fighters were measured, before and after the protocol. The combat consisted of four six-minute sessions with intervals of three minutes for recovery and measurement of the variables. Measurements were taken every 15 minutes, after the end of the fight. An increase in systolic (SBP) and mean BP (MAP) was observed after the last session. After 30 minutes, there was a decrease in MAP and SBP, until the end of the protocol. Diastolic BP (DBP) decreased after 30 minutes, returning to baseline after 45 minutes post-combat. HR remained high until 30 minutes of recovery. Despite the increase greater than 280% of the DP, verified immediately after the fight, 15 minutes of recovery was sufficient for this index to return to baseline values. The study shows that a jiu-jitsu match causes a significant increase in SBP and MAP, HR and PD with subsequent arterial hypotension.Keywords: cardiovascular physiological phenomena, blood pressure, martial arts.

Post Exercise Hypotension

We examined whether trained women exhibit similar cardiovascular and cardiac baroreflex alterations after a half-marathon compared to men. Thirteen women (39.1 ± 9.3 years; 165 ± 6 cm; 58.2 ± 7.5 kg; maximal aerobic speed (MAS): 13.7 ± 2.2 km·h−1) and 12 men (45.7 ± 10.5 years; 178 ± 7 cm; 75.0 ± 8.3 kg; MAS: 15.8 ± 2.2 km·h−1) ran an official half-marathon. Before and 60-min after, cardiovascular variables, parasympathetic (heart rate variability analysis) modulation and cardiac baroreflex function (transfer function and sequence analyses) were assessed during supine rest and a squat-stand test. Running performance was slower in women than in men (120 ± 19 vs. 104 ± 14 min for women and men, respectively). However, when expressed as a percentage of MAS, it was similar (78.1 ± 4.6% and 78.2 ± 5.4% of MAS for women and men, respectively). Before the run, women exhibited lower mean blood pressure (BP), cardiac output (CO) and stroke volume (SV) compared to men, together with higher parasympathetic indexes. After the race, parasympathetic indexes decreased in both sexes, but remained higher in women. Reduced SV, systolic BP and cardiac baroreflex were observed in men but not in women. Contrary to men, a competitive half-marathon did not trigger post-exercise hypotension and a reduced cardiac baroreflex in women.

Post Exercise Hypotension

Background and objective: Post-exercise hypotension, the reduction of blood pressure after a bout of exercise, is of great clinical relevance. Resistance exercise training is considered an important contribution to exercise training programs for hypertensive individuals and athletes. In this context, post-exercise hypotension could be clinically relevant because it would maintain blood pressure of hypertensive individuals transiently at lower levels during day-time intervals, when blood pressure is typically at its highest levels. The aim of this study was to compare the post-exercise cardiovascular effects on Paralympic powerlifting athletes of two typical high-intensity resistance-training sessions, using either five sets of five bench press repetitions at 90% 1 repetition maximum (1RM) or five sets of three bench press repetitions at 95% 1RM. Materials and Methods: Ten national-level Paralympic weightlifting athletes (age: 26.1 ± 6.9 years; body mass: 76.8 ± 17.4 kg) completed the two resistance-training sessions, one week apart, in a random order. Results: Compared with baseline values, a reduction of 5–9% in systolic blood pressure was observed after 90% and 95% of 1RM at 20–50 min post-exercise. Furthermore, myocardial oxygen volume and double product were only significantly increased immediately after and 5 min post-exercise, while the heart rate was significantly elevated after the resistance training but decreased to baseline level by 50 min after training for both training conditions. Conclusions: A hypotensive response can be expected in elite Paralympic powerlifting athletes after typical high-intensity type resistance-training sessions.

ABSTRACT OBJECTIVE To quantify the intensity adopted by walkers in public squares and check the occurrence and magnitude of post-exercise hypotension in the spontaneously adopted intensity and in a prescribed intensity. METHODS In 98 volunteers (38 of them being hypertensive), walkers in public squares of the city of João Pessoa, State of Paraíba, Brazil, we have identified the intensity of a usual training monitored by heart rate and we have investigated the occurrence and magnitude of post-exercise hypotension. Subsequently, participants were instructed to walk with moderate intensity. Blood pressure was measured after rest and during post-exercise recovery. RESULTS Of the total participants, 41% of the hypertensive and 36% of the normotensive individuals walked with light intensity. With the prescription, intensity increased to 55% and 52%, for the hypertensive and normotensive individuals, respectively. In the usual and prescribed intensity, the hypertensive individuals had post-exercise hypotension of -3.7±11.6 mmHg and -4.72±12.8 mmHg, respectively. There was no correlation between post-exercise hypotension and the initial systolic component of the hypertensive individuals (r2 = 0.2; p < 0.002). CONCLUSIONS Walkers in public squares choose light intensity for walking. When they exercise with the prescribed intensity, they increase the intensity, but the magnitude of the PEH is not increase with this guidance.

Introdução:O envelhecimento está relacionado a uma série de alterações no organismo, como redução das capacidades fisiológicas respiratória e circulatória, e aumento da hipertensão arterial sistêmica. Entretanto, a prática de atividade física pode melhorar a saúde do idoso e o controle da pressão arterial. Dentre as atividades físicas procuradas por idosos, está a hidroginástica.Objetivo: Avaliar as variáveis hemodinâmicas em idosas pré e pós-aula de hidroginástica.Métodos: Estudo observacional transversal. Participaram do estudo 10 idosas praticantes de hidroginástica. O critério de inclusão foi estar na prática de hidroginástica há mais de seis meses com, no mínimo, duas sessões de treinamento por semana. Foram coletados dados de frequência cardíaca e pressão arterial sistólica e diastólica, antes e após a aula de hidroginástica, com duração de 60 minutos, composta de aquecimento, parte principal e volta à calma, realizando movimentos articulares dos ombros, cotovelos, coluna, quadris e joelhos, alongamentos para os músculos dos membros superiores e inferiores e coluna de forma estática, seguido de exercícios estacionários e em movimento.Resultados: A amostra apresentou média de idade de 67,5±4,28 anos e média de Índice de Massa Corporal (IMC) de 27,37±2,89 kg/m2. Foram encontradas diferenças significativas na pressão arterial sistólica (PAS) (148±21,97 mmHg; p=0,029), na frequência cardíaca (FC) (94,5±12,08 bpm; p<0,001) e no duplo produto (DP) (13793±2781,38 mmHg. bpm; p<0,001) entre pré e pós-aula de hidroginástica.Conclusão: A atividade de hidroginástica praticada por idosos pode elevar a pressão arterial em mulheres idosas, principalmente a PAS, além de elevar a FC e o DP, indicando uma maior sobrecarga cardíaca como efeito agudo.Hemodynamic Variations in Elderly before and after Exercises in HydrogymnasticsIntroduction: Aging leads to a number of changes in the body, such as reduced physiological capacities (respiratory and circulatory) and increased systemic arterial hypertension. However, the practice of physical activity can improve the health and the blood pressure control of the elderly. Hydrogimnasctics is among the physical activities sought by the elderly.Objective: To evaluate the hemodynamic variables in the elderly before and after the hydrogymnastics class.Methods: This was an observational and seccional study. The sample consisted of 10 elderly women practicing hydrogymnastics. The participants practiced hydrogymnastics for more than 6 months with at least two training sessions per week. Heart rate and blood pressure data were collected before and after the 60-minute hydrogymnastics session, composed of warming up, main part and cool-down, performing joint movements of the shoulders, elbows, spine, hips and knees, stretches to upper and lower limb muscles and column, statically, followed by stationary and moving exercises.Objective: To evaluate the hemodynamic variables in the elderly before and after the hydrogymnastics class.Results: The sample presented mean of age of 67.5±4.28 years and mean of Body Mass Index (BMI) of 27.37±2.89 kg/m2. Significant differences were found in the measurement of systolic blood pressure (SBP) (148 ± 21.97 mmHg; p=0.029), heart rate (HR) (94.5 ± 12.08 bpm; p<0.001) and double product (DP) (13793 ± 2781.38 mmHg.bpm; p<0.001) after the hydrogymnastics class.Conclusion: The hydrogymnastic activity practiced by the elderly can increase the blood pressure, especially the SBP, HR and increase the DP, indicating a greater cardiac load as an acute effect.

The present study aimed to determine the effect of the intensity of aerobic and resistance exercise on the 24h BP response in normotensive women. Twenty-four women (aged 33 ± 9 years) performed five experimental sessions in randomized order: CON - no exercise; AE50 - 50% of heart rate reserve (HRR); AE70 - 70% of HRR; RE40 - 40% of 1repetition maximum (RM) and RE70 - 70% of 1RM. Systolic and diastolic BP and HR measurements were measured during 24h post-exercise at the participant's workplace. The AE50, AE70 and RE40 sessions led to the greatest and longest-lasting effects on the SBP, which persisted for up to 24h. For the DBP, the experimental sessions led to similar results; post exercise hypotension was observed until 7h post-exercise, with the exception of the AE70 session, which produced effects that persisted for 24h. Results shows that both aerobic and resistance exercise performed during the morning can decrease the mean BP above the baseline lasting 24 hours during a normal daily work. The aerobic exercise performed around 50% of HRR can better regulate both systolic and diastolic BP in this population.

SummarySmoking has many harmful effects on human body. It is well known that smoking is one of the most important risk factors for cardiovascular diseases. Though the ingredients from cigarette smoke stimulate the release of vasoconstrictor and reduce the release of vasodilator substances, the goal of this study was to investigate the acute effects of smoking on arterial blood pressure, heart rate and blood vessel flow.The investigation was conducted on forty healthy volunteers divided into two groups of twenty non-smokers (control group), and twenty smokers (experimental group). The group of smokers was examined before and after smoking four cigarettes during one hour. Blood pressure and electrocardiograph (ECG) were measured by common methods. Brecht’s and Boucke’s methods of plethysmography were used to evaluate the peripheral circulation.There were no differences in measured systolic and diastolic blood pressure and recorded ECG between non-smokers and smokers, neither between smokers before and after smoking. However, heart rate was increased by 29.57% after smoking in comparison to the value before smoking.Evaluation of plethysmographic parameters showed that amplitude was significantly decreased. Parameters of peripheral resistance were very increased: ductility was decreased by over 20%.It can be concluded that acute smoking does not significantly affect the level of blood pressure, although it increases heart rate. The shape of plethysmograms showed decreased systolic filling and decreased diameters of blood vessels.

ABSTRACT Introduction: L-Arginine supplementation increases plasma levels of nitric oxide (NO) metabolites, an important mediator of peripheral dilatation. Therefore, L-Arginine supplementation can improve the duration and magnitude of post-exercise hypotension. Objectives: This study investigated the effects of L-Arginine supplementation on post-exercise hypotension, femoral artery area and heart rate variability in elderly women. Methods: Twenty prehypertensive and hypertensive adult female participants were divided (in a random and balanced manner) into two groups (placebo and L-arginine). The participants ingested eight grams of inert substance (placebo group) or eight grams of L-Arginine (L-arginine group), dissolved in water, 90 min prior to the experimental session. The experimental session consisted of an isokinetic maximal strength test. Blood pressure was measured using an oscillometric device (Omron MX3 Plus, Bannockburn, US) every 10 minutes for 60 minutes after the experimental session. Femoral artery area (ultrasound) and heart rate variability were also analyzed. Data underwent repeated measures (ANOVA) analysis and respective assumptions. Results: L-Arginine supplementation associated with exercise produced a significant decrease in systolic blood pressure [placebo vs L-Arginine] (p <0.05) at the “half-life” time point (90 minutes after supplementation) (141±12 vs 130±11 mmHg) and 40 min. (146±13 vs 127±13 mmHg), 50 min. (145±20 vs 127±15 mmHg) and 60 min. (147±19 vs 129±14mmHg) post-exercise. No significant differences were identified in femoral artery area and heart rate variability. Conclusion: Acute L-Arginine supplementation can increase post-exercise hypotension effects in elderly women. Additionally, acute L-Arginine supplementation is not related to either femoral artery area or heart rate variability responses. Level of evidence I; Randomized clinical trial.

AbstractThis study aimed to assess whether obesity and/or maximal exercise can change 24 h cardiac autonomic modulation and blood pressure in young men. Thirty-nine men (n: 20; 21.9±1.8 kg·m−2, and n: 19; 32.9±2.4 kg·m−2) were randomly assigned to perform a control (non-exercise) and an experimental day exercise (after maximal incremental test). Cardiac autonomic modulation was evaluated through frequency domain heart rate variability (HRV). Obesity did not impair the ambulatory HRV (p>0.05), however higher diastolic blood pressure during asleep time (p=0.02; group main effect) was observed. The 24 h and awake heart rate was higher on the experimental day (p<0.05; day main effect), regardless of obesity. Hypotension on the experimental day, compared to control day, was observed (p<0.05). Obesity indicators were significantly correlated with heart rate during asleep time (Rho=0.34 to 0.36) and with ambulatory blood pressure(r/Rho=0.32 to 0.53). Furthermore, the HRV threshold workload was significantly correlated with ambulatory heart rate (r/Rho=− 0.38 to−0.52). Finally, ambulatory HRV in obese young men was preserved; however, diastolic blood pressure was increased during asleep time. Maximal exercise caused heart rate increase and 24h hypotension, with decreased cardiac autonomic modulation in the first hour, regardless of obesity.
