There exists no examination of what is the minimum anti-hypertensive threshold intensity for isometric exercise training. Twenty two normotensive participants were randomly assigned to training intensities at either 5 % or 10 % of their maximal contraction. Twenty participants completed the study. Clinical meaningful, but not statistically significant, reductions in systolic blood pressure were observed in both 5 % and 10 % groups –4.04 mm Hg (95 % CI –8.67 to +0.59, p=0.08) and –5.62 mm Hg (95 % CI –11.5 to +0.29, p=0.06) respectively after 6 weeks training. No diastolic blood pressure reductions were observed in either 5 % –0.97 mm Hg (95 % CI –2.56 to +0.62, p=0.20) or 10 % MVC +1.8 mm Hg (95 % CI –1.29 to +4.89, p=0.22) groups respectively after training. In those unable to complete isometric exercise at the traditional 30 % intensity, our results suggest there is no difference between 5 and 10 % groups and based on the principle of regression to the mean, this could mean both interventions induce a similar placebo-effect.

Isometric Handgrip Exercise

Context: High blood pressure is one of the leading preventable causes of cardiovascular death worldwide. In this regard, several studies have shown interest in the benefits of isometric exercise on blood pressure regulation. Objective: To assess whether low-intensity isometric handgrip exercise (LI-IHE) is an effective strategy to lower blood pressure levels in prehypertensive and hypertensive patients. Data Source: This study was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement and registered with PROSPERO. Potentially eligible studies were identified after a systematic search conducted on 4 international databases: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), PEDro, and SPORTDiscus. Study Selection: We included randomized controlled trials that comprised patients who received LI-IHE. Study Design: Systematic review with meta-analysis. Level of Evidence: Level 3. Data Extraction: Data related to patient characteristics, exercise programs, risk-of-bias assessment, and outcomes of interest were systematically reviewed independently by 2 authors. Results: The following reductions (mean differences) were observed after LI-IHE: systolic blood pressure (SBP), (MD) = −5.43 mm Hg; (95% CI, −8.47 to −2.39; P = 0.0005); diastolic blood pressure (DBP), −2.41 mm Hg (95% CI, −4.33 to −0.48; P = 0.01); mean arterial pressure (MAP), −1.28 mm Hg (95% CI, −2.99 to 0.44; P = 0.14). Conclusion: LI-IHE seems to lower SBP, DBP, and MAP values in prehypertensive and hypertensive adults. It appears that LI-IHE reduces, in greater magnitude, blood pressure levels in hypertensive patients, specifically in patients aged <45 years, those who are overweight, and those on medications. Nevertheless, substantial heterogeneity in the main results and in the analyses by subgroups generated uncertainty about the real reduction magnitude that LI-IHE can produce on blood pressure.

This study aims to determine the effectiveness of Isometric Handgrip Exercise and Slow Respiratory Respiratory Exercise. Quasi Experimental Research design with research design Two Group Pretest Postest Design on 32 respondents. The results showed that there was systolic and diastolic after Handgrip Isometric Exercise intervention (t = 8,279, p = 0,000), (t = 6,154, p = 0,000), and the importance was done after Slow Deep Slow Deep Respiratory Exercise (t = 3,632 , p = 0.002), (t = 4.226, p = 0.001). Thus, it can be concluded that good or slow isometric exercise exercises in breathing exercises can reduce blood pressure. The results of the study were handgrip isometric training and slow slow breathing exercises as nursing interventions that can be carried out independently in providing nursing care for patients with hypertension.

Isometric Handgrip Exercise

Aerobic and isometric training have been shown to reduce resting blood pressure, but simultaneous aerobic and isometric training have not been studied. The purpose of this study was to compare the changes in resting systolic (SBP), diastolic (DBP), and mean arterial blood pressure (MAP) after 6 weeks of either (i) simultaneous walking and isometric handgrip exercise (WHG), (ii) walking (WLK), (iii) isometric handgrip exercise (IHG), or control (CON). Forty-eight healthy sedentary participants (age 20.7 ± 1.7 yrs, mass 67.2 ± 10.2 kg, height 176.7 ± 1.2 cm, male n=26, and female n=22) were randomly allocated, to one of four groups (n=12 in each). Training was performed 4 × week−1 and involved either treadmill walking for 30 minutes (WLK), handgrip exercise 3 × 10 s at 20% MVC (IHG), or both performed simultaneously (WHG). Resting SBP, DBP, and MAP were recorded at rest, before and after the 6-week study period. Reductions in resting blood pressure were significantly greater in the simultaneous walking and handgrip group than any other group. These results show that simultaneous walking and handgrip training may have summative effects on reductions in resting blood pressure.

Isometric Handgrip Exercise

Blood pressure (BP) reactivity is predictive of the development of cardiovascular disease. We hypothesized that the BP response at the onset of isometric handgrip exercise would occur earlier and to a lesser degree in individuals who underwent bariatric surgery compared with obese adults and that the reliance on total peripheral resistance (TPR) would be attenuated. Twenty-six individuals (7 nonobese, 11 obese, 8 postbariatric surgery) completed isometric handgrip exercise (40% maximum voluntary contraction) to exhaustion. Heart rate (HR, ECG) and arterial BP (brachial catheter) were measured continuously. Stroke volume was estimated from the pressure waveform, and cardiac output (CO) and TPR were calculated. Peak change, time to peak, and rate of rise in BP were assessed during the first 30 s of exercise. Obese adults exhibited a slower rise in BP and higher peak BP at exercise onset compared with nonobese controls ( P < 0.05). Peak BP and the rate of rise were not different between individuals who underwent bariatric surgery and nonobese controls ( P > 0.05). Nonobese controls exhibited an exercise-mediated increase in CO, whereas obese adults increased TPR ( P < 0.05). The increases in CO and TPR were less apparent in individuals who underwent bariatric surgery ( P > 0.05). In contrast to obese adults, individuals who underwent bariatric surgery exhibit a rapid rise in BP at exercise onset. This rapid increase in BP is associated with a fall in TPR and results in lower peak BP at the onset of isometric exercise. These data suggest that bariatric surgery improves BP reactivity via changes in the time course of hemodynamic responses. NEW & NOTEWORTHY Bariatric surgery has been shown to reduce the blood pressure (BP) response to isometric handgrip exercise. By examining the time course of the BP response to exercise, we found, in contrast to obese adults, individuals who underwent bariatric surgery exhibit a rapid rise in BP at exercise onset, which is associated with a fall in total peripheral resistance and results in lower peak BP at the onset of isometric exercise. These data suggest that bariatric surgery improves BP reactivity via reflex autonomic adjustments.

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.
