Study Overview
Brief Summary
This project aims to identify the effect of a 3-week Grand Tour (e.g. Tour de France, Giro d'Italia, and Vuelta a España) on sleep, hematological parameters and the serum metabolome in world-class cyclists.

Outcomes
Primary Outcomes
Sleep efficiency during the Grand Tour
Time Frame: Every night starting from one week before till the last night of the Grand Tour
Percentage change in sleep efficiency during the Grand Tour (measured by OURA ring)
Total sleep time during the Grand Tour
Time Frame: Every night starting from one week before till the last night of the Grand Tour
Change in total sleep time during the Grand Tour (measured by OURA ring)
Blood haemoglobin concentration
Time Frame: Start of the Grand Tour - restday 1 of the Grand Tour - restday 2 of the Grand Tour - last day of the Grand Tour
Change in the blood haemoglobin concentration during the Grand Tour
Serum metabolome abundance of cyclists participating in a Grand Tour
Time Frame: Start of the Grand Tour - restday 1 of the Grand Tour - restday 2 of the Grand Tour - last day of the Grand Tour
Changes in the abundance of serum metabolites within the cyclists between 4 timepoints (measured by mass spectrometry)
Secondary Outcomes
- Light sleep(Before the start of the Tour - restday 1 - restday 2 - end of Grand Tour)
- REM sleep(Before the start of the Tour - restday 1 - restday 2 - end of Grand Tour)
- Deep sleep(Before the start of the Tour - restday 1 - restday 2 - end of Grand Tour)
- Wakefulness after sleep onset(Every night starting from one week before till the last night of the Grand Tour)
- Red blood cell concentration(Start of the Grand Tour - restday 1 of the Grand Tour - restday 2 of the Grand Tour - last day of the Grand Tour)
- Subjective fatigue(Start of the Grand Tour - restday 1 of the Grand Tour - restday 2 of the Grand Tour - last day of the Grand Tour)
