  • Title: The effect of interval and continuous training on the aerobic parameters.
    Author: Overend TJ, Paterson DH, Cunningham DA.
    Journal: Can J Sport Sci; 1992 Jun; 17(2):129-34. PubMed ID: 1324106.
    Abstract:
    The purpose of this study was to investigate changes in the parameters of aerobic function resulting from continuous training (CT) and interval training of both low power (LPO-IT) and high power output (HPO-IT). Untrained males (n = 17, 25.1 yrs) trained 10 weeks on cycle ergometers (four 40-min sessions a week) at 80% VO2max. Cycle ramp function tests at 0 and 10 weeks were used to determine the four aerobic parameters:VO2max, ventilation threshold (VeT), effective time constant for O2 uptake kinetics (MRT), and work efficiency (eta): VO2max increased significantly (3.30 to 3.66 l.min-1). Absolute VeT increased significantly (2.17 to 2.45 l.min-1) but there was no change in the relative threshold (VeT/VO2max). MRT decreased significantly from 38.8 to 33.1 seconds and there was no change in eta. There were no between-group differences; thus neither low power output nor high power output interval training offers an advantage over continuous training of the same average power output in altering the aerobic parameters.
