Different types of high-intensity interval training (HIIT) sessions are used by athletes in order to improve their physical performance, but innovative approaches to training are lacking. Therefore, in Part A of this study the physiological response to a standard HIIT and a new decremental exercise training (DECT) will be compared in runners and cyclists. Next, in Part B the training effects of a 4-week block of the HIIT and DECT will be compared.

| Primary | Change in exercise performance | Time taken to cover a fixed distance, in minutes | measured before and after the 4-week training block, during a time-trial (40 km cycling or 10 km running) | |
| Secondary | Change in maximal oxygen uptake | Measured in ml/kg/min | Measured during a maximal incremental exercise test before and after the 4-week training block | |
| Secondary | Average oxygen uptake | Average oxygen uptake measured during the four 4-min bouts of high-intensity exercise of a session of HIIT and DECT | The two training session are performed within one week |
