Investigating the Effects of Diet and Physical Activity on Esport Performance

A randomized, counterbalanced intervention study in esport players.

Study Overview

• Status: Not yet recruiting
• Conditions: Dietary Habits; Diet, Healthy; Sports Physical Therapy

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
