Resistance exercises training
Knee extensors
They were performed three times a week. The muscles were trained: (a) Knee extensors and flexors, (b) Ankle plantar flexors, (c) Pectorals, (d) Scapula stabilizers, (e) Shoulder abductors, (f) Lumbar extensors, (g) Abdominals, and (h) Hip adductors. To determine the training load, the test of One-Repetition Maximum (1RM) was used. Three decreasing sets were performed (12/10/8 repetitions) with 60% of 1RM in the upper limbs and 80% in the lower limbs. The non-amputated limb made the same load as the amputee to equalize the forces between the limbs. Loads were adjusted every two weeks following the progression principle.
