Fig 2. Continuous aerobic group and super-circuit group–training protocols.

Notes: The figure illustrates the training modalities (i.e., treadmill, bike, hand cycle and resistance training) used in each training group. Each training modality is denoted in a different color. The numbers that appear inside the boxes denote the number of minutes engaged in the designated training modality; in the super-circuit group, in weeks 1–2, 3–6 and 7–12, the rest interval was of two minutes, one and a half minute and one minute, respectively.
