Cardiopulmonary Exercise Testing (CPX)
Table 2 provides the CPX main data. After the training period, the TRAINING group showed a significant increase in exercise duration (baseline 524±95 vs 4M 636±131 secs; P =0.001), maximum workload achieved (baseline 126±49 vs 4M 151±65 W; P =0.007) and peak VO2 (baseline 21.7±5.2 vs 4M 23.4±5.9 ml/kg/min;P =0.04). In the CONTROL group a significant increase in exercise duration was found (baseline, 491±93 vs 4M, 593±93 secs;P =0.006).
At the end of the 4-month follow-up, no differences were observed in the variations (deltas) of the values ​​over the several parameters measured between the groups. Analyses of exercise duration and VO2 deltas are provided in the Supplementary Data III.
