Data presented as the means ± standard deviation except for RPEmax and Dyspneamax, which are presented as the medians (interquartile range). p-value for comparison between the men and the women. BMI: body mass index; RPE: rating of perceived exertion; CR10: category ratio; HR: heart rate; W: Watt; VO2: oxygen uptake; MET: metabolic equivalents of task; max: highest value during the test.
