Cardiometabolic syndrome (CMS) is classified as a combination of maladaptive cardiovascular and metabolic abnormalities that includes hypertension, dyslipidemia, and blood vessel dysfunction. These outcomes can negatively influence hemodynamics (HDYN) via a decrease in myocardial efficiency due to increased afterload and/or decreased vascular elasticity. Studies have reported changes in HDYN during and following acute exercise in clinical populations. However, there is a paucity of information on how high-velocity circuit resistance training (CRT) compared to continuous treadmill exercise (TM) affects these parameters at rest. PURPOSE: To compare the effects of CRT, TM and no exercise (CONT) on HDYN variables at rest in older adults with multiple CMS risk factors. METHODS: Eleven women (66.4 ± 6.4 years) participated in 12-weeks of CRT or TM. Stroke volume (SV), cardiac index (CI), systemic vascular resistance (SVR), end-diastolic volume (EDV), ejection fraction (EF), and oxygen consumption (rV02) were measured by impedance electrocardiography and indirect calorimetry before and after training. RESULTS: A within-group analysis revealed significant increases in CI (MD= 0.257, SE= .092, p=.023) and EDV (MD= 31.10, SE= 11.96, p=.032), a trend towards an increase in SV (MD=8.63, SE=4.28 p=.07) and a decrease in SVR (MD=−154.15, SE=71.07, p=.06) for CRT. TM resulted in significant increases in CI (MD=.218, SE=.080, p=.026) and EDV (MD=26.16, SE=10.36, p=.035); however, increases were not comparative to those seen with CRT. The CONT group showed a significant decrease in rVO2 (MD=−1.60, SE=.64, p=.03). No significant differences were observed for EF. At post-testing CONT resulted in a decrease in rVO2 approaching significance compared to TM (MD=−3.10, SE=1.12, p=.07). CRT demonstrated more favorable changes in SV, CI, SVR and EDV than TM or CONT. However, these changes did not reach statistical significance. CONCLUSION: These preliminary results indicate that CRT and TM lead to significant favorable changes in CI and EDV, however, CRT showed greater improvements in each and a trend towards improvements in HDYN when compared to TM and CONT. It is expected that completion of testing on existing subjects will further strengthen our results.
