- Running speed (% of maximal aerobic speed), weight (% of 1-RM) and physiological responses during 3 weeks of increasing workload (HR – heart rate bpm (% of HR max); VO2 – oxygen uptake (mL/kg/min, %VO2 peak*); RER – respiratory exchange ratio; RPE – rating of perceived exertion). The metabolic parameters were recorded every minute and averaged for the 5 min of treadmill running for the 1st and 4th exercise set. RPE was recorded during the last 15 s per minute of each running bout
