Beaufort, G. (2023). Mitigating Hypertension Risk in College-Aged Black and White Women Using Isometric Handgrip Training: A Randomized Control Trial. Unc Charlotte Electronic Theses And Dissertations.
Hypertension is the most prevalent risk factor for future development of cardiovascular disease, the leading cause of death worldwide. Isometric exercise training (IET) has been shown to decrease blood pressure and resting heart rate in certain populations, but its impact on young (18-25 years) women is not well understood. Further, black women may especially benefit from IET due to several factors including healthcare discrimination, psychosocial factors, and worse cardiovascular health profiles compared to white women of the same age. Eleven young white and black women were selected to participate in either eight weeks of IET using a handgrip dynamometer (n = 5) or eight weeks of a non-intervention control protocol (n = 6). Baseline measurements of resting systolic blood pressure, diastolic blood pressure, and resting heart rate were compared to post-intervention levels. Analysis of this data showed an average change in systolic blood pressure (0.04 ± 9.37), diastolic blood pressure (2.21 ± 6.5), and resting heart rate (-6.12 ± 10.73) for the control group. The handgrip IET group showed an average change in systolic blood pressure (0.75 ± 8.36), diastolic blood pressure (0.75 ± 6.3), and resting heart rate (-0.48 ± 6.63). No statistically significant differences were found between baseline and postintervention for any of the response variables
