Abstract

The main objective was to observe the physiological responses of non-professional triathletes to a 4-week HIIT training program with a significantly reduced exercise volume. VO2max and power at 1st and 2nd ventilatory thresholds increased significantly while cycling and running performance were unchanged, despite an overall reduction in training time. To control the workload among participants, the rating of perceived effort (RPE) load method (RPE X time) was used. This has been shown to be an easy, reliable method. Performance differences between genders in moderately trained triathletes were tested during a maximal incremental cycle ergometer test, a simulated 20 km cycling time trial and a 5 km run. Significant changes in physiological and performance variables were found for both genders during the maximal cycle test. However, there were differences in responses between genders in the 20 km cycling time trial.
