Isometric exercise and its effect on blood pressure and heart rate; a comparative study between healthy, young, and elderly males in and around Raichur city
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 6, Issue 1
Abstract
Introduction: Isometric exercise is a routine part of everyday activities and occupational tasks. Physicians have a responsibility to promote regular physical activity to reduce high blood pressure (BP) and to control weight as physical inactivity is considered as a risk factor for coronary artery disease. Isometric exercises for aging populations have often been discouraged due to harmful effects on the cardiovascular system. However, isometric exercise in older adults and patients of some age group has found to be beneficial for maintaining normal cardiovascular function, but still, controversies are there. The cardiovascular response to isometric exercise has been studied majorly in young adult males. The vascular wall becomes less elastic and stiffer with the advancement of age (Nichols et al., 1985; O’Rourke, 1990; and Cheitlin, 2003). There are very few studies that have compared the isometric exercise response in younger and elderly individuals. Purpose of the Study: The present study is done to determine the effect of isometric exercise on BP and heart rate (HR) in healthy, young, and elderly males. Materials and Methods: In the present study, 100 male subjects with age group of 20–30 years and 60–70 years satisfying the inclusion criteria were selected and divided into two groups, namely, young and elderly group, respectively. Resting HR and BP were recorded followed by HR and BP responses to isometric exercise in both the groups. Isometric contraction was held till 60 s using the force transducer at 40% of the maximal voluntary contraction. Pre and post HR and BP were compared. Results: The elder subjects had a lower HR and a higher BP response than their younger counterparts. Conclusion: From this study, it is concluded that the increasing age is associated with an altered HR and BP response to isometric exercise.
