The Functional Training Group (FT) used elastic bands and the Resistance Exercise Group (RE) used weight training machines. The FT patients performed functional training and RE performed resistance exercises for the following muscles group: upper limbs, lower limbs and trunk. It was used a machine "leg extension" for the training on the lower limbs. For upper limbs the investigators used a pulley triceps machine and front pull in addition to free weights (dumbbells).
In order to perform the exercise program, the study followed all the recommendations established by the American College of Sports Medicine (ACSM) (Ratamess et al., 2009). It was carried out two exercises for major muscle groups and one exercise for small muscles. The exercises were divided in 3 sets of 12 repetitions for each muscle group. The intensity of the exercises was 60% of one-maximum repetition (1RM).
The exercise program involved pectoral exercises: crucifix and seat supine; biceps: alternated screw; triceps: triceps pulley; back: standing handsaw and pulled ahead; quadriceps: leg extensor and finally gluteus: standing hips extension.
The patients were instructed to maintain their daily activities and to avoid any other nonpharmacological treatment.
