Student’s t test was used for the comparison of continuous variables. * p value < 0.05. AT: anaerobic threshold; BR: breathing reserve; FR: frequency rate; HR: hearth rate; OUES: oxygen uptake efficiency slope; PCP: peak circulatory power; SD: standard deviation; VE: ventilation rate; VE/VCO2: minute ventilation/carbon dioxide production; VO2: pulmonary oxygen uptake; WR: work rate.
