The Effect of Consuming a guaraná and Vitamin/Mineral Complex Pre-exercise on Affect, Exertion, Metabolism and Cognition

Phase 4

Completed

• Conditions: Affect and Exertion During and Post-exercise

• Registration Number: NCT01929694
• Lead Sponsor: Northumbria University

Brief Summary

Consuming a guaraná and vitamin and mineral complex can improve mental fatigue and cognitive function at rest; guaraná also contains caffeine, which can reduce perceived exertion and increase fat burning during exercise. The purpose of this study is to test whether consuming a guaraná and vitamin and mineral product before exercise influences affect (mood), physical exertion and fat burning during exercise and mental fatigue, cognitive performance and affect post-exercise.
