简要总结
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.

研究组 & 干预措施
DECT Group
The DECT session consists of four bouts of 4 min high-intensity "decremental" exercise with 3 min of active recovery between bouts. Load is progressively decreased throughout each exercise bout. The training period will last for a total of 4 weeks, with three weekly sessions of supervised training
干预措施: DECT (Other)
HIIT Group
The HIIT session consists of four bouts of 4 min high-intensity "decremental" exercise with 3 min of active recovery between bouts. Load is kept constant throughout each exercise bout. The training period will last for a total of 4 weeks, with three weekly sessions of supervised training
干预措施: HIIT (Other)
结局指标
主要结局
Change in exercise performance
时间窗: measured before and after the 4-week training block, during a time-trial (40 km cycling or 10 km running)
Time taken to cover a fixed distance, in minutes
次要结局
- Change in maximal oxygen uptake(Measured during a maximal incremental exercise test before and after the 4-week training block)
- Average oxygen uptake(The two training session are performed within one week)
