Hypertensive patients have high blood pressure and poor cardiovascular health and it is known that hypertension negatively affects people's health-related quality of life. Meta-analyses have shown that isometric handgrip training (IHT) reduces blood pressure in hypertensives, but the effects of IHT on health-related quality of life is unknown. Therefore, we tested the hypotheses that the IHT improves health-related quality of life in hypertensives. In this randomized controlled trial, 48 hypertensive individuals were randomly assigned to two groups: IHT and control. IHT was completed thrice weekly (4 × 2 min at 30% of maximal voluntary contraction). Before and after 12 weeks health-related quality of life was assessment through Medical Outcomes Study Questionnaire Short Form 36 (SF36). No signi?cant effect was observed for physical function (IHT: 85.6±4.6 vs. 81.1±7.2; Control: 78.6±76.7±4.9), physical problems (IHT: 71.4±10.1vs. 83.9±8.1; Control: 73.8±8.2 vs. 64.3±8.0), general health (IHT: 56.1±3.7 vs. 57.1±1.9; Control: 54.3±1.6 vs. 57.6±2.1), pain (IHT: 23.6±4.6 vs. 30.7±5.8; Control: 32.9±4.5 vs. 31.9±4.3), social aspects (IHT: 46.4±3.6 vs. 50.0±2.3; Control: 48.8±2.7 vs. 48.8±1.7), emotional problems (IHT: 85.7±8.4 vs. 92.9±5.2; Control: 79.4±7.8 vs. 71.4±6.6), mental health (IHT: 61.7±2.8 vs. 58.0±2.5; Control: 54.5±2.4 ± 55.6±1.9), and vitality (IHT: 60.0±4.3 vs. 58.6±4.0; Control: 50.7±2.9 vs. 53.6±3.0) after 12-weeks of supervised IHT (p>0.05 for all). In conclusion, 12-weeks of IHT does not improve health-related quality of life in hypertensives. Therefore, in order to improve quality of life, other exercises should be an indicator for hypertensive patients.
