14 To date, IET interventions have consisted of a limited number of exercises, with the most studied being IHG interventions. 14– 18 Recently, isometric handgrip (IHG) training (a form of isometric resistance exercise training (IET)) has been introduced into formal guidelines, most notably by the American College of Cardiology and the American Heart Association in their 2017 Guidelines. 13Īs noted above, increased physical activity is a cornerstone lifestyle modification for hypertension management, with guidelines around the world overwhelmingly recommending aerobic exercise training with dynamic resistance training as an adjuvant intervention. 12 These treatments have no deleterious side effects and are comparatively low in cost. 11 These interventions include weight reduction, dietary alterations including sodium and alcohol restriction, and increased physical activity. Lifestyle modification treatments are a widely recommended approach to reduce BP. 8– 10 These, together with the high cost of hypertension to the national health service (NHS), make lifestyle modification treatments essential. 5, 6 The significant public health burden that hypertension represents highlights the importance of effective antihypertensive treatments.ĭespite the proven efficacy of pharmacological antihypertensive treatments, 7 less than 50% of medicated hypertensives adhere to treatment for numerous reasons, including deleterious side effects, and many often fail to achieve clinical targets. 3, 4 A reduction in blood pressure (BP) is associated with a reduced risk of developing CVD. 2 Hypertension is a major risk factor in the development of cardiovascular disease (CVD) and coronary heart disease (CHD). Globally, hypertension is estimated to affect ~30% population 1 and is the leading risk factor for global mortality causing an estimated 9.4 million deaths a year. Thus, this study indicates the IB device to be an effective alternative to the ZON that can also be used to perform other IE modalities. Despite the ZON group having larger reductions in BP, no significant differences were found between the two devices. No significant changes were seen in HR or strength ( p > 0.05).Ĭonclusion: The results of this study indicate that both the ZON and IB devices elicit significant SBP, DBP and MAP reductions. Postintervention diastolic BP (DBP) was reduced in both intervention groups (ZON 66.6☗.4 mmHg, p = 0.004 IB 65.7☑0.0 mmHg, p = 0.012) compared to CON (71.1☘.8 mmHg). Results: Postintervention systolic BP (SBP) was significantly lower in both ZON (114.5☘.2 mmHg, p = 0.000) and IB (119.9☗.0 mmHg, p = 0.000) compared to control (131.0☑2.4 mmHg). Resting BP, heart rate (HR) and IHG strength were measured in all groups at baseline and postintervention. The intervention groups completed 3 sessions each week of 4, 2 min IHG at 30% maximal voluntary contraction, with a 1-min rest, for 4 weeks.

Methods: Twenty-three healthy participants (29.10☒.19 years old, 173.95☓.83 cm, 75.43±5.06 kg, SBP 127.10☑0.37 mmHg, DBP 70.40☖.77 mmHg) were randomly allocated to either a control group (CON) or 2 isometric handgrip (IHG) training groups that used the Zona plus (ZON) and IB devices. Purpose: The aim of this study was to test the BP-lowering effectiveness of this prototype. In response, a novel more versatile, isometric exercise (IE) device, the IsoBall (IB) was created. However, the protocols used are often limited by cost/immobility and the use of rigid exercise modalities. Isometric resistance exercise training reduces blood pressure (BP). Background: Hypertension is the leading risk factor for global mortality.
