“…Wiles et al stated that, currently, there are no definitive statements, positional declarations nor recommendation guidelines for the use of isometric exercise and that there has been a continued reluctance to promote isometric exercise by committees and organizations that are charged with the responsibility for public health recommendations of physical activity [ 24 ]. A good number of scientific studies clearly demonstrate that isometric exercise is efficacious in the attenuation of resting blood pressure in both normotensive and hypertensive subjects [ 24 , 25 , 26 , 27 , 28 ]. Meta-analysis by different authors reports that isometric exercise produced greater reductions in systolic and diastolic blood pressure compared to dynamic exercise training [ 29 , 30 ].…”

Decline in normal physiological pulmonary function has been attributed to premorbid conditions such as prehypertension. Research evidence suggests that physical activity reduces age-related decline in pulmonary function and improves the efficiency of the lungs in prehypertensive patients. However, there is a scarcity of data evidence relating to isometric exercise and pulmonary function. Furthermore, the interrelationship between the intensity and duration of isometric exercise and pulmonary function in these patients is still uncertain. Therefore, this study was undertaken to investigate the effect of isometric handgrip exercise on pulmonary function capacity in adults with prehypertension. To determine the effectiveness of isometric handgrip exercise on pulmonary function capacity in adults with prehypertension. A quasi experiment using a pre- and post-exercise method was carried out in two out-patients hospital settings. The sample comprised 192 sedentary pre-hypertensive subjects, aged between 30–50 years, that were randomly distributed into three groups of 64 participants each. The subjects performed, for 24 consecutive days, an isometric handgrip exercise at 30% Maximum Voluntary Contraction (M.V.C.). At the end of the 24 days, group one (GP1) discontinued, while group two (GP2) continued the exercise protocol for another 24 consecutive days and group three (GP3) continued with the exercise protocol for another 24 consecutive days but at 50% M.V.C. Determinants of lung function (outcomes) were Forced Expiratory Volume in 1 s (FEV1), Forced Vital Capacity (FVC), FEV1/FVC Ratio and Peak Expiratory Flow Rate (PEFR). The study shows that there was no statistically significant difference in the pre- and post-exercise outcomes for FEV1, FVC, FEV1/FVC Ratio and PEFR after 24 days for group 1. In group 2, there was a statistically significant difference in the FVC [(mean = 0.12 ± 0.12), (p = 0.002)], FEV1 [(mean = 0.15 ± 0.17), (p = 0.003)] and PEF [(mean = 0.85 ± 0.35), (p = 0.001)] after 48 days. In group 3, there was a statistically significant difference (p = 0.001) in all the outcomes assessed after 48 days. There was a between groups difference in favour of group 2 compared with group 1 for outcomes of FEV1 [(mean = 0.142 ± 0.68), (p = 0.005)] and PEF [(mean = 0.83 ± 0.19), (p = 0.0031)]. There was statistically significant difference in favour of group 3 compared to group 2, by increasing the exercise intensity from 30% to 50% M.V.C., for outcomes of FVC [mean change = 0.10 ± 0.052), (p = 0.005)], FEV1/FVC [mean change = 3.18 ± 0.75), (p = 0.017)] and PEF [(mean change = 0.86 ± 0.35), (p = 0.001)] after 48 days. Isometric handgrip exercise (after 48 days at 30% to 50% M.V.C.) improves outcomes of pulmonary function capacity in adults with prehypertension. Meanwhile, duration and/or increase in intensity of the isometric effort significantly contributed to the affects attained.

“…O estudo de Olher et al 25 não encontrou resposta hipotensora 60 minutos após o exercício isométrico no handgrip em idosos hipertensos em intensidade de 30% e 50% da contração voluntária máxima. A partir de um ponto de vista prático, os resultados do presente sugerem que não há efeitos agudos do ERI sobre a PA e que seus benefícios se restringem após um período de treinamento 15 .…”

“…Nesse sentido, recentemente Araujo et al 15 propuseram um novo modelo de treinamento de ERI, o qual utilizou três séries de um circuito composto por seis exercícios à 60% de 1 repetição máxima (1RM). Diferente de outros protocolos de ERI, este modelo atende a requisitos mínimos de volume e intensidade para a melhora de aptidões físicas relacionadas à saúde e é aplicável em academias de forma semelhante ao ERD.…”

Resumo Objetivo: Comparar respostas hemodinâmicas e autonômicas cardíacas após sessões agudas de exercício resistido dinâmico e isométrico. Método: Após familiarização às sessões experimentais e teste de uma repetição máxima, 12 homens (idade: 49.0±6.4 anos) sem o uso de medicamentos e experiência em exercício resistido foram randomizados de forma cruzada à duas sessões experimentais de exercício resistido dinâmico e isométrico realizados compostos por um circuito de seis exercícios alternados por segmento corporal e à uma intensidade de 60% de uma repetição máxima. Aos momentos de repouso e recuperação foram mensuradas a pressão arterial sistólica e diastólica e registrado os intervalos R-R com posterior cálculo de índices da variabilidade da frequência cardíaca. Resultados: Não foram observadas diferenças estatisticamente significantes nas respostas pressóricas entre as sessões experimentais. O duplo produto se recuperou para valores basais aos 25min da recuperação em ambas as sessões. A frequência cardíaca permaneceu mais elevada durante momentos da recuperação na sessão dinâmico, ao passo que a sessão isométrica recuperou menos batimentos cardíacos para essa mesma variável. Adicionalmente, o balanço simpato-vagal permaneceu elevado e indicadores parassimpáticos diminuídos, em relação ao repouso, após sessão isométrica. Conclusão: Não ocorreram diferenças nas respostas hemodinâmicas entre as sessões de exercício resistido. Por outro lado, demonstrou-se diferentes recuperações para a frequência cardíaca variáveis autonômicas após as sessões experimentais. Resumen Objetivo: Comparar respuestas hemodinámicas y autonómicas cardíacas después de sesiones agudas de ejercicio resistido dinámico e isométrico. Método: Después de familiarización en las sesiones experimentales y prueba de una repetición máxima, 12 hombres (edad: 49.0±6.4 años) sin el uso de medicamentos y experiencia en ejercicio resistido fueron randomizados de forma cruzada a dos sesiones experimentales de ejercicio resistido dinámico y isométricos compuestos por un circuito de seis ejercicios alternados por segmento corporal con una intensidad del 60% de una repetición máxima. Durante los momentos de reposo y recuperación se midieron la presión arterial sistólica y diastólica y se registraron los intervalos R-R con posterior cálculo de índices de la variabilidad de la frecuencia cardíaca. Resultados: No se observaron diferencias estadísticamente significativas en las respuestas de presión arterial entre las sesiones experimentales. El doble producto se recuperó a valores basales a los 25min de la recuperación en ambas sesiones. La frecuencia cardiaca permaneció más elevada durante momentos de recuperación en la sesión dinámica, mientras que la sesión isométrica recuperó menos latidos cardíacos para esa misma variable. Todavía, el balance simpático-vagal permaneció elevado e indicadores parasimpáticos disminuidos, en relación al reposo, después de la sesión isométrica. Conclusión: No ocurrieron diferencias en las respuestas hemodinámicas entre las sesiones de ejercicio. Sin embargo, se demostró diferentes recuperaciones entre las variables autonómicas después de las sesiones experimentales. Abstract Objective: To compare hemodynamic and cardiac autonomic responses after acute sessions of dynamic and isometric resistance exercise. Methods: After familiarization with the experimental sessions and maximal repetition test, 12 men (age: 49.0±6.4 years) without medication and experience in resistance exercise were cross-randomized in two experimental sessions of dynamic and isometric resistance exercise composed by a circuit with six alternating exercises per corporal segment and at intensities of 60% of a one maximum repetition. At rest and recovery moments, systolic and diastolic blood pressure were measured and R-R intervals were recorded with subsequent calculation of heart rate variability indexes. Results: No statistically significant differences were observed in blood pressure responses between experimental sessions. The rate pressure product recovered to baseline at 25 min of recovery in both sessions. The heart rate remained higher during moments of recovery in the dynamic session, while the isometric session recovered fewer heart beats for that same variable. In addition, the sympatho-vagal balance remained high and the parasympathetic indicators decreased in relation to rest after an isometric session. Conclusion: There were no differences in hemodynamic response between resistance exercise sessions. Otherwise, different recoveries between the autonomic variables after the experimental sessions are demostrated.

“…Regular aerobic exercise lowers resting systolic blood pressure by 5-7 mmHg on average, while resistance training exercise lowers resting systolic blood pressure by 2-3 mmHg in those with hypertension (6) . Exercise can be broadly categorized in two ways: dynamic (isotonic) or static (isometric) and within each of these categories, handgrip exercise (7) .…”

Hypertension (HTN) is a major risk factor contributing to cardiovascular disease, which is the main cause of death world wide. Isometric handgrip strength(HGS) exercise, a non-pharmacological lifestyle modification, has been recommended as a first-line treatment for hypertension. This study aimed to examine the effect of isometric handgrip strengthening exercise on blood pressure among hypertensive patients. Subjects: a quasi-experimental research design was conducted on sixty medicated hypertensive patients and divided attentively into two equal groups. Control group which, exposed to routine hospital care only. While study group was followed the isometric handgrip strength exercise program. Two tools were used for collecting data Tool I Patients' Assessment Interview Schedule and Tool II International Physical Activity Questionnaire-Long Form (IPAQ-LF).Results: there was a statistically significant reduction in systolic blood pressure between the study group with Mean ± SD (111.50±7.23 mmHg) and control group (126.16±7.32 mmHg) after 10 weeks of an exercise program with statistical significance between both groups at PV = .00 . There was a significant reduction in diastolic blood pressure between the study group with Mean ± SD (71.33±5.58mmHg) and control group (79.50±7.37 mmHg) with statistically significant between both groups after 10 weeks of exercise programPV = .00 . Conclusion: isometric handgrip exercise significantly reduced the SBP and DBP within 10 weeks of the study duration &therefore, the prescription of isometric handgrip exercise in addition to other lifestyle modifications should be encouraged for the hypertensive patient
