Summary
A randomized, controlled trial to evaluate the effects of two versions of 10 high intensity interval trainings (HIIT) within a 7-day shock microcycle on endurance performance, well-being, health, stress and recovery in trained athletes.
Detailed description
Thirty-six trained endurance athletes will be recruited and randomly assigned to either a "high volume (HIIT-HV)" group, a "low volume (HIIT-LV)" group, or a control group. All participants will be monitored before (9 days), during (7 days), and after (14 days) a 7-day training intervention, for 30 days. Participants in both intervention groups will complete 10 HIIT sessions within the period of 7 days, with an additional 30 minutes of low-intensity training exclusively in HIIT-HV. HIIT sessions consist of aerobic HIIT, i.e., 5x4min at 90-95% of maximal heart rate interspersed by 2.5 min active recovery periods. To determine the effects of the intervention, performance diagnostics, and a 5 kilometer time trial will be conducted before and after the intervention. In addition, participants are closely monitored for general health, stress, fatigue, recovery, neuromuscular performance, executive functions and sleep.
