Abstract

This investigation aimed to determine the effects of 24 weeks of resistance training (RT) on cardiac function in older women. Seventy-three physically independent older women were selected for this investigation. Participants were randomized into a training group (TG, n = 38) and a control group (CG, n = 35). The RT program was conducted over 24 weeks and consisted of three sessions a week. Participants performed eight exercises for the whole body in three sets of 8–12 repetitions. Tissue Doppler echocardiography was performed, according to current guidelines, before and after 24 weeks of the intervention. One-repetition maximum (1-RM) tests were used to assess muscular strength. A group vs. time interaction (P < 0.05) was shown for left ventricular end-diastolic volume (TG = − 8.3% vs. CG = − 0.6%), left ventricular end-systolic volume (TG = − 10.6% vs. CG = + 1.1%), and left atrial volume index (TG = − 9.1% vs. CG = + 3.9%). A main time effect (P < 0.05) was found for left ventricular mass index (TG = + 4.9% vs. CG = − 0.6%), septal thickness (TG = + 3.3% vs. CG = − 1.7%), left ventricular ejection fraction (TG = + 3.7% vs. CG = − 0.5%), E’/E septal (TG = − 4.8% vs. CG = + 0.5%), deceleration time (TG = − 4.1% vs. CG = + 3.9%), E septal (TG = + 4.6% vs. CG = − 0.6%), and E lateral (TG = + 5.2% vs. CG = − 1.1%). These results suggest that 24 weeks of RT improves cardiac morphological and functional variables in older women. Graphical Abstract: (Figure presented.)
