In healthy individuals, periodized aerobic training has been considered superior than traditional methods; however, its effect on COPD patients has not yet been elucidated. Aim: To evaluate the effect of periodized aerobic training on aerobic power and autonomic modulation in COPD patients. Methods: 16 COPD patients were included in the study and randomized to either periodized training (PTG; N=10) or control group (CG; N=6). Aerobic power (cardiopulmonary exercise testing) and autonomic function (heart rate variability) were assessed at baseline and after 12 weeks of training. Linear periodized aerobic training was conducted in 3 mesocycles with a 4 weeks duration each. Comparison between baseline and 12 weeks was performed using paired Student{\textquoteright}s t test or the Wilcoxon test, in case of non-normally distributed data. Results: After 12 weeks of periodized training, PTG presented a huge increase in peak oxygen consumption in either total (0.72{\textpm}0.39 to 1.9{\textpm}1L/min; P=0.01) or relative values (VO2peak, 9.4{\textpm}4 to 27.2{\textpm}16.8 ml/kg/min; P=0.01) and it was also observed an increase in the parasympathetic response (HF index, 62.3{\textpm}46.8 to 113.2{\textpm}62.1 ms; P=0.04). In addition, after training it was observed an increase in maximal speed reached during peakVO2 (5.5{\textpm}1.2 to 6.3{\textpm}1.3 km/h; P=0.006) in PTG. No significant difference for any outcome was observed in CG (P\>0.05). Conclusion: Periodized aerobic training promoted enormous benefits on the aerobic capacity and autonomic modulation in patients with COPD.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/44/Suppl_58/P605}, eprint = {https://erj.ersjournals.com/content}, journal = {European Respiratory Journal} }
