Abstract
- Cardiovascular (CV) disease accounts for one third of deaths in females, with hypertension (HTN) and type 2 diabetes mellitus (T2DM) risk factors for its development. Global longitudinal strain (GLS) is a strong prognostic indicator for future CV dysfunction and can be impaired in women with HTN and T2DM. This study aimed to determine if exercise impacts GLS in women with HTN or T2DM. A randomized crossover trial was conducted with 15 women (aged 64.1 ± 4.7) diagnosed with HTN (n = 12) or T2DM (n = 3). Participants completed an 8‐week exercise and 8‐week non‐exercising control period, separated by a 21.6 ± 14.2‐week washout period. Resting echocardiography and exercise testing were performed pre and post each arm to measure GLS and aerobic fitness (VO2peak). GLS (%) improved significantly following exercise (−16.8 ± 1.5 to −18.4 ± 1.8; p ≤ 0.001, d = 0.98), but not control (−17.2 ± 2.0 to −16.9 ± 1.4; p = 0.585, d = −0.14). Similarly, VO2peak (mL/kg/min) increased following exercise (18.0 ± 2.1 to 19.2 ± 2.6; p ≤ 0.001, d = 0.53), but not control (17.5 ± 2.7–17.2 ± 2.7; p = 0.269, d = −0.12). There were significant between‐group differences for GLS (p ≤ 0.001, d = 1.02) and VO2peak (p = 0.011, d = 0.63). Aerobic exercise positively impacts GLS and VO2peak in women with HTN and T2DM. GLS may inform exercise professionals regarding the early effectiveness of an aerobic exercise intervention and infer a reduction in CV disease risk. Highlights: The impact of aerobic exercise on global longitudinal strain (GLS), and other measures of cardiovascular (CV) function, was explored in women with hypertension and type 2 diabetes.Eight weeks of aerobic exercise significantly improved GLS (very large effect; d = 1.02) and aerobic capacity (moderate effect; d = 0.63) compared to control.Improvements observed in GLS and aerobic capacity were clinically meaningful. Significant reductions in systolic and diastolic blood pressure were also observed following exercise, but not control.GLS can measure the effectiveness of aerobic exercise on myocardial function in women at risk of developing CV disease.
