Unsteady physiology and perception during long “steady state” runs. What role do training characteristics play?

Master's thesis in Sports science (ME517) PURPOSE: To contribute to a better understanding of low-intensity (<LT1) endurance training by quantifying and explaining the physiological mechanisms associated with cardiac drift and fatigue during low-intensity running and relate them to training characteristics. […] RESULTS: There was a significant drift for heart rate, oxygen consumption, ventilation, RER and RPE during both runs (P<0.05). There was no difference in drift between groups for any measurements, except for running economy during LR100. The drift was similar during LR90 and LR100 for all measurements except RER, which was significantly greater during LR90 (P<0.05). CONCLUSION: The p…
