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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sleep efficiency during the Grand Tour | 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 | 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) |
| Serum metabolome abundance of cyclists participating in a Grand Tour | 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) |
| Blood haemoglobin concentration | 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 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 | Change in red blood cell concentration during the Grand Tour |
| Wakefulness after sleep onset | Every night starting from one week before till the last night of the Grand Tour | Percentage change in wakefulness after sleep onset during the Grand Tour (measured by OURA ring) |
| 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 | Absolute change in subjective fatigue during the Grand Tour (measured by 11-point scale) |
| Light sleep | Before the start of the Tour - restday 1 - restday 2 - end of Grand Tour | Percentage change in light sleep during the Grand Tour (measured by OURA ring) |
| Deep sleep | Before the start of the Tour - restday 1 - restday 2 - end of Grand Tour | Percentage change in deep sleep during the Grand Tour (measured by OURA ring) |
| REM sleep | Before the start of the Tour - restday 1 - restday 2 - end of Grand Tour | Percentage change in REM sleep during the Grand Tour (measured by OURA ring) |
