Progressive resistance training for two years reduced left ventricular mass index by 5.5% and improved various cardiac parameters in older women compared to a control group.
Does a supervised progressive resistance training program improve cardiac structure and function in physically independent older women?
A two-year supervised progressive resistance training program significantly improves echocardiographic markers of cardiac structure and function in physically independent older women.
Absolute Event Rate: 0% vs 0%
Purpose: This randomized controlled trial investigated the effects of a supervised progressive resistance training (RT) program conducted over two years on cardiac structure and function in older women. Methods: Sixty-four physically independent older women (≥ 60 years) were recruited for this investigation. Participants were randomly assigned to either a training group (TG, n = 33) or a control group (CG, n = 31). The RT program was conducted over two years, in three sessions per week, on nonconsecutive days, and included eight whole-body exercises performed in three sets of 8–12 repetitions. Echocardiographic assessments were performed both before and after a two-year period by an experienced echocardiographer who was blinded to the participant's status and group assignment. Results: A group-by-time interaction was found ( P < 0.05) for the left ventricular mass index (TG = -5.5% vs. CG = +11%), septal thickness (TG = -3.8% vs. CG = +7.3%), posterior wall thickness (TG = -2.8% vs. CG = +13.6%), left ventricular end-diastolic volume (TG = -9.0% vs. CG = +20.0%), left ventricular end-systolic volume (TG = -7.8% vs. CG = +23.3%), left atrial volume index (TG = -7.1% vs. CG = +28,1%), the left ventricular ejection fraction (TG = -1.0% vs. CG = -4.9%), the E’/E septal (TG = -11.0% vs. CG = +22.1%), the E septal (TG = +14.9% vs. CG = -19.2%), and the E lateral (TG = +12.7% vs. CG = -22.8%). Conclusions: Our results suggest that a two-year follow-up of the RT intervention may improve both the cardiac morphological and functional parameters in older women.
