Investigating the Effects of Diet and Physical Activity on Esport Performance

Study Overview
=================
Brief Summary
-----------------
A randomized, counterbalanced intervention study in esport players.

Detailed Description
-----------------
The study will test whether i) the consumption of two different carbohydrate drinks and ii) the performance of regular high-intensity interval training will impact esport performance and metabolic profile.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in esport performance (test battery) | Reaction time will be measured using an esport test battery | 4 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Glucose response (continuous glucose monitor): 3h iAUC | The 3h incremental area under the curve (iAUC) will be used to assess glycemic response to the drink. Unit: mg/dL | 4 weeks | 
| Glycaemic variability (continuous glucose monitor): 24h MAGE | The mean amplitude of glycemic excursion during 24h will be assessed as an indicator for glycemic variability. Unit: mg/dL | 4 weeks |
