Comparison of the Effect of Two Types of Physical Exercises in Patients With Heart Failure With Preserved Ejection Fraction

Patients will exercise for 40 minutes three times a week on an ergometric bicycle at 50-60% of VO2max, 60-70% of HRmax, 11-13 on the Borg scale, without ergometer at 50-60% of VO2max, 60-70% of HRmax, 11-13 on the Borg scale, without shortness of breathing difficulty. In addition, strength training will be performed (bench press, leg press, leg curl, leg machine, bench press, leg press, leg curl, leg curl, leg machine). leg curls, leg curls, rowing machine, triceps dips, pectoral pull-ups) twice a week. week. Strength training will be performed with 15 repetitions per exercise and per session, with a corresponding workload of 15 repetitions. session, with a workload corresponding to 60% to 65% of the 1-repetition maximum (1RM) measured at (1RM) measured at the beginning and at the end of the intervention.

Patients will perform three training sessions per week. Each training session begins with a 10-minute warm-up at moderate intensity (corresponding to 50-60% of VO2max, 60-70% of HRmax, 11-13 on the Borg scale, no shortness of breath) before cycling, four 4-minute intervals at high intensity (corresponding to 85-90% of VO2max, 90-95% of HRmax, 15-17 on the Borg scale, shortness of breath). Each interval will be separated by 3 minutes of active pauses, with a HRmax of 50-70%. The training session will end with 3 minutes of cool down at moderate intensity (corresponding to 50-60%). moderate intensity (corresponding to 50-60% of VO2max, 60-70% of HRmax, 11-13 on the Borg scale, without difficulty). Borg scale, no shortness of breath). The total exercise time will be 40 minutes for the HIIT group.
