The purpose was to evaluate the inter-individual BP responses after beach tennis, aerobic, resistance and combined exercise sessions in adults with hypertension. We conducted a post hoc analysis of pooled crossover randomized clinical trials from six previously published studies of our research group, and analyzed data from 154 participants with hypertension (≥35 years). BP was assessed using office BP, and the mean changes throughout the 60 min after recreational beach tennis (BT, n = 23), aerobic (AE, n = 18), combined (COMB, n = 18), and resistance (RES, n = 95) exercise sessions were compared to a non-exercising control session (C). To categorize the participants as responders and non-responders for PEH, the typical error (TE) was calcul...

However, considerable inter-individual variability in RM performed at a given %1RM has been reported in previous studies on this topic. Aim: To compare the number of repetitions performed at 60, 75, and 90%1RM in lower and upper limb resistance exercises in older adults. Fifteen men aged between 60 and 75 years performed two preliminary sessions (familiarization + and 1RM tests) and three experimental sessions (RM tests at 60, 75, and 90%1RM on knee extension and elbow flexion exercises). Movement velocity for each concentric and eccentric muscle action was 1.5-2 s. Statistical comparisons regarding the RM performed in each %1RM were tested using the Generalized Estimating Equations analysis. Results: The RM during knee extension exercise was significantly lower when compared to elbow flexion at 60% 1RM. On the other hand, the RM during knee extension exercise was significantly higher when compared to elbow flexion at 90%1RM. A similar number of repetitions at 75%1RM were performed in both exercises. Conclusion: Physically active older men can perform different RM at 60% and 90%1RM in knee extension and elbow flexion exercises, suggesting that the use of a specific RM range cannot be associated to the same percentage of 1RM in this individuals.

However, the effectiveness of exercise programs is associated with its continuity and regularity, and the long-term adherence to traditional exercise interventions is often low. Recreational sports emerge as an alternative, being more captivating and able to retain individuals for longer periods. Besides, sport interventions have demonstrated improvements in physical fitness components that are associated with a lower incidence of hypertension. However, no studies have investigated the effects of recreational sports on 24 h ambulatory blood pressure. The aim of the present study is to evaluate the effect of beach tennis training on ambulatory blood pressure and physical fitness in individuals with hypertension. Methods This study will be a randomized, single-blinded, two-arm, parallel, and superiority trial. Forty-two participants aged 35–65 years with previous ...

O TP caracteriza-se pelo uso séries submáximas (40% a 60% de uma repetição máxima), executando-se a fase concêntrica o mais rapidamente possível. Séries submáximas podem reduzir a demanda cardiovascular durante a sessão, quando comparada a do exercício resistido tradicional, que usualmente utiliza séries máximas, maiores intensidades ou um maior número de repetições por série. Ainda, estudos recentes tem demonstrado redução sustentada dos níveis de pressão arterial (PA) após uma única sessão de exercício, fenômeno conhecido como hipotensão pós-exercício. A flutuação excessiva desses valores ao longo do tempo tem sido sugerida como importante variável para avaliação de risco cardiovascular, independentemente dos valores médios de PA. No entanto, os potenciais efeitos do exercício sobre a variabilidade de PA permanecem pouco explorados. O objetivo do presente estudo foi avaliar o efeito de uma sessão de TP sobre a variabilidade de PA em indivíduos idosos com hipertensão. Métodos: Neste ensaio clínico randomizado cruzado, 23 participantes foram submetidos a uma sessão de treinamento de potência e uma sessão controle. A sessão de TP consistiu em 3 séries de 10 repetições em 5 exercícios: legpress, supino reto, cadeira extensora, remada em pé e cadeira flexora. A sessão controle foi realizada em repouso sentado. Ambas as sessões experimentais tiveram duração aproximada de 40 minutos. Após cada sessão, a PA dos participantes foi avaliada por 24h através da monitorização ambulatorial de PA. Desses dados, extraíram-se as medidas de PA sistólica e diastólica, que foram incluídas em um software programado para calcular a variabilidade real média dessas medidas. Resultados: Ao comparar a variabilidade real média (mmHg) após as sessões experimentais, não foi observada diferença na variabilidade da PA sistólica de 24 horas (TP

Effects of a single beach tennis session on short-term blood pressure variability in individuals with hypertension

We investigated the acute effects of a single beach tennis (BT) session on short-term BP variability in individuals with hypertension. Twenty-two participants took part in this randomized clinical trial. They were randomly allocated to a BT session and a nonexercise control session (Con). BT and Con sessions lasted 45 min. Office BP and heart rate were measured throughout the experimental sessions to calculate rate-pressure products and estimate the cardiovascular demand of BT. To determine short-term BP variability after BT and Con sessions, average real variability (ARV) of systolic BP and diastolic BP was assessed over 24 h using ambulatory BP monitoring. Compared with Con, there were lower 24-h (Δ, -0.9 ± 0.4 mmHg; P = 0.049) and daytime (Δ, -1.4 ± 0.5 mmHg; P = 0.004) ARV of diastolic BP after BT. There were no significant differences in ARV of systolic BP between Con and BT. There was a higher rate-pressure product found during BT (P < 0.001). However, after the experimental sessions, there was no significant difference between BT and Con for the rate-pressure product under ambulatory conditions. In conclusion, a single BT session reduced daytime and 24-h diastolic BP variability in adults with hypertension. Trial registration: ClinicalTrials.gov, NCT03909308.

Methods: Twenty-four older adults with essential hypertension participated in two experimental sessions in a randomized order: the PT composed of 3 sets of 8-10 repetitions in 5 power training exercises and the nonexercise control at seated rest (Con). Both experimental sessions lasted 40 min. Office BP was measured continuously for 1 h in the laboratory and 24 h BP through ambulatory blood pressure monitoring. Results: Compared with Con, office systolic/diastolic BP decreased after PT (Systolic BP: 10 mmHg, p < 0.001; Diastolic BP: 4 mmHg, p = 0.015). A trend toward decrease (p = 0.06) was found in diastolic ambulatory BP during daytime (2 mmHg; p = 0.062) and nighttime (3 mmHg; p = 0.063) after PT. No differences were found between PT and Con sessions for systolic and mean ambulatory BP. Conclusion: A single bout of PT decreases office BP but this hypotensive effect is not sustained under ambulatory conditions in older patients with essential hypertension.

METHODS In this randomized crossover trial, 24 participants (12 men and 12 women) randomly performed two experimental sessions: a beach tennis session and a non-exercise control session. The beach tennis session started with a standardized 5-min warm-up consisting of basic techniques, followed by three 12-min beach tennis matches with 2-min intervals between them. Heart rate was continuously recorded and rating of perceived exertion was assessed in the middle and at the end of each set during the beach tennis session. Enjoyment was also assessed after the beach tennis session. The control session was performed in seated rest. Both experimental sessions lasted 45 min. Ambulatory blood pressure was measured continuously for 24 h after sessions. RESULTS Systolic blood pressure (24-h: 6 mmHg, P = 0.008; daytime: 6 mmHg, P = 0.031; nighttime: 6 mmHg, P = 0.042) and diastolic blood pressure (24-h: 3 mmHg, P = 0.021; daytime: 3 mmHg, P = 0.036; nighttime: 4 mmHg, P = 0.076) decreased after beach tennis when compared with control. The participants presented a reserve heart rate of 59-68%, and a rating of perceived exertion score of 3.4-4.7 using Borg's CR10 Scale. The enjoyment scores after beach tennis session were higher than 90%. CONCLUSION A single session of recreational beach tennis reduces 24-h ambulatory blood pressure in adults with hypertension. Additionally, the participants can achieve a high physiological stress but perceive less effort during the practice.

METHODS Search was conducted using the databases at PubMed, Scopus, Cochrane Library and EMBASE, for randomized trials comparing the chronic effects (≥4 weeks) of HIIT versus MICT or control group (non-exercise) on BP in older adults (≥60 years) with or without hypertension. RESULTS A total of 10 articles (n = 266 participants) were included in this meta-analysis. HIIT were associated with reductions in systolic BP (MD -7.36; 95%CI -11.80 to -2.92; P < 0.01; I2 = 24%) and diastolic BP (MD -5.48; 95%CI -8.71 to -2.25; P < 0.01; I2 = 40%) versus control group. No differences were found between HIIT and MICT in systolic BP (MD -2.09; 95%CI -9.76 to 5.58; P = 0.59; I2 = 0%) and diastolic BP (MD -1.00; 95%CI -6.01 to 4.01; P = 0.69; I2 = 0%). CONCLUSION HIIT reduces BP in older adults. Additionally, HIIT and MICT provided comparable reductions on BP in this population.

Results: Compared with Con, office systolic/diastolic BP decreased after PT (Systolic BP: 10 mmHg, p < 0.001; Diastolic BP: 4 mmHg, p = 0.015). A trend toward decrease (p = 0.06) was found in diastolic ambulatory BP during daytime (2 mmHg; p = 0.062) and nighttime (3 mmHg; p = 0.063) after PT. No differences were found between PT and Con sessions for systolic and mean ambulatory BP. Conclusion: A single bout of PT decreases office BP but this hypotensive effect is not sustained under ambulatory conditions in older patients with essential hypertension.

Recreational beach tennis reduces 24-h blood pressure in adults with hypertension: a randomized crossover trial

METHODS In this randomized crossover trial, 24 participants (12 men and 12 women) randomly performed two experimental sessions: a beach tennis session and a non-exercise control session. The beach tennis session started with a standardized 5-min warm-up consisting of basic techniques, followed by three 12-min beach tennis matches with 2-min intervals between them. Heart rate was continuously recorded and rating of perceived exertion was assessed in the middle and at the end of each set during the beach tennis session. Enjoyment was also assessed after the beach tennis session. The control session was performed in seated rest. Both experimental sessions lasted 45 min. Ambulatory blood pressure was measured continuously for 24 h after sessions. RESULTS Systolic blood pressure (24-h: 6 mmHg, P = 0.008; daytime: 6 mmHg, P = 0.031; nighttime: 6 mmHg, P = 0.042) and diastolic blood pressure (24-h: 3 mmHg, P = 0.021; daytime: 3 mmHg, P = 0.036; nighttime: 4 mmHg, P = 0.076) decreased after beach tennis when compared with control. The participants presented a reserve heart rate of 59-68%, and a rating of perceived exertion score of 3.4-4.7 using Borg's CR10 Scale. The enjoyment scores after beach tennis session were higher than 90%. CONCLUSION A single session of recreational beach tennis reduces 24-h ambulatory blood pressure in adults with hypertension. Additionally, the participants can achieve a high physiological stress but perceive less effort during the practice.

METHODS Search was conducted using the databases at PubMed, Scopus, Cochrane Library and EMBASE, for randomized trials comparing the chronic effects (≥4 weeks) of HIIT versus MICT or control group (non-exercise) on BP in older adults (≥60 years) with or without hypertension. RESULTS A total of 10 articles (n = 266 participants) were included in this meta-analysis. HIIT were associated with reductions in systolic BP (MD -7.36; 95%CI -11.80 to -2.92; P < 0.01; I2 = 24%) and diastolic BP (MD -5.48; 95%CI -8.71 to -2.25; P < 0.01; I2 = 40%) versus control group. No differences were found between HIIT and MICT in systolic BP (MD -2.09; 95%CI -9.76 to 5.58; P = 0.59; I2 = 0%) and diastolic BP (MD -1.00; 95%CI -6.01 to 4.01; P = 0.69; I2 = 0%). CONCLUSION HIIT reduces BP in older adults. Additionally, HIIT and MICT provided comparable reductions on BP in this population.
