“…Sex (male/female) dictory findings [17][18][19][20]. Similar to our results, Olher et al [17] did not find a reduction in resting BP up to 60 min following isometric handgrip exercise sessions (4 × 5 contractions of 10 s at 30 and 50 % of maximal voluntary isometric contraction; MVIC) in older females with hypertension.…”

“…As pointed out in the methods section, we prescribed the 4 × 1 min and not 4 × 2 min as the traditional isometric handgrip exercise protocol, because of the participants' tolerance and safety regarding the respiratory pattern and to avoid the Valsalva maneuver. Nonetheless, the non-occurrence of PEH up to 30 min post-exercise is similar to what has previously been observed in isometric handgrip exercise protocols, even using a higher volume of contractions (i. e., 8 min or 12 min) [17][18][19]. These studies used isometric handgrip exercise sets from 1 to 3 min, which suggests that the duration of contractions does not play a role in PEH when small muscle groups are involved in isometric exercise protocols.…”

“…Although PEH is well-documented following aerobic [14] and dynamic resistance exercise [15], there is a scarcity of studies that have investigated the occurrence (or not) of PEH following isometric exercise in individuals with hypertension [16]. Most studies have investigated the acute effect of isometric exercise on BP during a short-term period in laboratory settings [17][18][19][20], which limits clinically interpreting the findings. To the best of our knowledge, only three studies have investigated the acute effect of isometric exercise on ambulatory BP [21][22][23], but none of them exclusively included individuals with hypertension.…”

We investigated the acute effects of isometric biceps exercise on resting and ambulatory blood pressure in hypertensive adults. A total of 12 medicated hypertensive adults (aged 47±7 years; body mass index 27.2±2.7 kg/m2; resting blood pressure 123±12/74±6 mmHg) performed an isometric biceps exercise session (bilateral biceps exercise; 4×1 min at 30% of 1-RM, 2 min recovery) and a control session (without exercise) in a randomized order separated by a 7 to 10-day period. Resting blood pressure, heart rate, and heart rate variability indexes (SDNN, RMSSD, LF, HF, and LF/HF) were measured pre- and up to 30 min post-sessions. Next, ambulatory blood pressure was monitored during 22-hour post-sessions (awake and asleep periods). No significant changes were observed for resting blood pressure, heart rate, or heart rate variability indexes up to 30 min post-sessions (p>0.05). Furthermore, no significant differences were observed in average ambulatory blood pressure values in 22-hour (126±11/71±6 mmHg vs. 126±15/71±9 mmHg), awake (127±10/74±6 mmHg vs. 130±14/75±10 mmHg), and asleep (123±15/68±6 mmHg vs. 120±17/66±9 mmHg) periods between the control and isometric sessions, respectively (p>0.05). In conclusion, an isometric biceps exercise session does not elicit an acute antihypertensive effect in adults with hypertension, which suggests that its prescription to improve the acute BP control is limited.

Abstract. Background: Hypertension has a significant impact on public health and has become a major health care burden worldwide. One non-pharmacological therapy that can be given to reduce blood pressure in hypertensive patients is Isometric Handgrip Exercise exercise therapy. This therapy has been shown to reduce blood pressure which is almost the same as intense aerobic exercise. This literature review aims to analyze the effects of the application of Isometric Handgrip Exercise in reducing blood pressure in hypertensive patients. Method: This research explores quantitative evidence published in electronic databases such as Pubmed, and Google Scholar. Using a search strategy, we identified 16 articles that were potentially and relevant to the research objectives, and 4 articles were included in the final analysis. Results: We could see a significant effect on systolic and diastolic blood pressure reduction in the group given the Isometric Handgrip Exercise intervention compared with the control group. Conclusion: Research results from several articles in this review literature show that Isometric Handgrip Exercise exercises are proven to be effective in reducing blood pressure in hypertensive patients.

“…Badrov et al (2013) did not report any adverse events after 8 weeks of training. Studies have observed a modest increase in heart rate (Δ = 3 ± 4 bpm), systolic blood pressure (Δ = 16 ± 10 mm Hg) and diastolic blood pressure (Δ + 7 ± 6 mm Hg) during isometric exercise (Araujo et al, 2011), as well as no significant changes after the exercise (Farah et al, 2017;Silva et al, 2018;Silva et al, 2019).…”

Meta‐analyses have shown that isometric handgrip training reduces blood pressure in normotensive and hypertensive subjects. However, the effects on cardiac autonomic modulation are still controversial. Thus, the aim of this systematic review and meta‐analysis was to analyse the effects of isometric handgrip training on cardiac autonomic modulation in normotensive and hypertensive subjects. For this, Medline, Cinhal, Embase, Spordiscus and PEdro were searched for relevant studies published until December 2018. Randomized controlled trials investigating the effect of isometric handgrip training on heart rate variability parameters were considered eligible. Parameters were obtained in time (standard deviation of all the RR intervals‐SDNN, root mean square of successive differences between the normal adjacent RR intervals‐RMSSD and the percentage of adjacent intervals with more than 50 ms‐PNN50) and frequency domain (low frequency‐LF, high frequency‐HF and sympathovagal balance‐LF/HF). Mean difference (MD) and 95% confidence interval (95% CI) were calculated using an inverse variance method with a random effects model. Seven trials were included in the systematic review and meta‐analysis, totalling 86 participants. No significant effect was observed in heart rate variability parameters after isometric handgrip training (4 trials to SDNN: MD = −1.44 ms and 95% CI = −8.02, 5.14 ms; RMSSD: MD = −1.48 ms and 95% CI = −9.41, 6.45 ms; PNN50: MD = 0.85% and 95% CI = −1.10, 2.81%; 7 trials to LF: −0.17 n.u. and 95% CI = −6.32, 5.98 n.u.; HF: MD = 0.17 n.u. and 95% CI = −5.97, 6.30 n.u.; and LF/HF: MD = 0.13 and 95% CI = −0.34, 0.59). In conclusion, current literature indicates that isometric handgrip training does not improve heart rate variability.
