  • The results are presented as mean and SD.

  • *Pearson's correlation. Alpha was set to 0 .05 for all statistical analyses.

  • HR, heart rate; HRRDT, heart rate reached during test; HR 90%Vo2max, heart rate at 90% of maximal oxygen consumption; PMHR, predict maximum heart rate;RHR, resting heart rate; VO2max, maximal oxygen consumption; 90%VO2max, 90% of the maximal oxygen consumption; RPE 90%Vo2max, Borg's RPE Scale values at 90% of maximal oxygen consumption.
