Summary

Purpose: This study aimed to determine the effect of 48 weeks of resistance training (RT) on cardiac function in older women. Methods: Sixty-four older women (≥ 60 years), physically independent, were selected for this study. Participants were randomized into a training group (TG, n = 33) and a control group (CG, n = 31). The RT program was conducted over 48 weeks, three sessions a week, on nonconsecutive days, in the morning hours. Participants performed eight exercises for the whole body (chest press, horizontal leg press, seated row, leg extension, triceps pushdown, lying leg curl, preacher curl, seated calf raise) in three sets of 8-12 repetitions. The echocardiography was performed according to current guidelines before and after 48 weeks by an experienced echocardiographer blinded to patient status and group assignment. One-repetition maximum (1-RM) tests were used to analyze muscular strength. Glusoce, lipid profile, and C-reactive protein were measured. DEXA was used to measure body fat and muscle mass.

Resistance training

Resistance training program. The RT program was performed over 48 weeks, three times per week (Mondays, Wednesdays, and Fridays), during the morning, in the University fitness facility. Participants were personally supervised by Physical Education professionals (1-2 supervisors per exercise) with substantial RT experience to ensure consistent and safe exercise performance. Participants performed four exercises for the trunk and upper limbs and four exercises for the lower limbs in three sets of 8-12 repetitions. T Rest intervals were 1-2 and 2-3 min between sets and exercises. The training load was individually adjusted for each exercise weekly, according to the number of repetitions performed during the last training session, to ensure that the subjects kept performing at the ideal intensity for the repetition zone. In these situations, training loads were increased by 2-5% for upper-limb exercises and 5-10% for lower-limb exercises.
