Randomized Controlled Study to Investigate the Impact of Different Intensities Training on ADL and BODE Index in COPD

The LIRT group initiated the resistance training for UL with 30% of the 1RM, with 5% increases each nine sessions; therefore, the maximum load was 45% of the 1RM. The LL training initiated with 30% of the 1RM, increasing 7% each nine sessions, thus, the maximum load was 51% of the 1RM. Each exercise session consisted of three sets of 15 repetitions, with a 2 minutes interval between sets.

the initial load for HIRT group was 60% of 1RM for UL with 5% increases each nine sessions; therefore, the maximum load reached 75% of the 1RM. The LL training initiated with 60% of the 1RM with 7% increments each nine sessions, as a result, the maximum load after 36 sessions was 81% of the 1RM. These patients underwent three sets of eight repetitions, with two minutes intervals between sets.

Patients underwent an aerobic training in cycle ergometer, with load intensity determined as the same load the patient presented a VO2 value of 70-80% of the peak VO2 obtained in the symptom-limited CPET. Each session of aerobic training lasted 20-30min according to patient's tolerance.
