Affect and Exertion During and Post-exercise Clinical Trial
Official title:
The Effect of Consuming a Guaraná and Vitamin and Mineral Complex Before a Morning Exercise Session on Affect, Exertion and Substrate Metabolism During Exercise and Cognitive Performance During the Post-exercise Recovery Period
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.

| Other | Cognitive Function | Participants will complete a set of cognitive tasks (Immediate Word Recall, Choice Reaction Time, Rapid visual information processing task, Numeric Working Memory, Delayed word Recall, Word Recognition and Picture Recognition) measuring episodic memory, working memory, attention and decision making. | Assessed at baseline, pre-exercise and immeadiately and 75min post-exercise | No |
| Other | Mood | Assessed using the Bond-Lader Visual Analogue Scales (VAS) and Energy VAS (concentration, physical stamina, mental stamina) | Assessed at baseline, pre-exercise and immeadiately and 75min post-exercise | No |
| Other | Substrate Metabolism | Measured using an online gas analysis system (Cortex). Oxygen uptake, carbon dioxide production, fat and carbohydrate oxidation and energy expenditure will be measured for 1 min at each 10min interval. | Measured at 10min intervals during exercise | No |
| Primary | Affect | Affect measured using the Feeling Scale and Felt Arousal Scale | Assessed pre-exercise, at 10min intervals during exercise and 45 and 75min post-exercise | No |
| Secondary | Exertion | Rate of perceived exertion measured using the Borg scale | Measured at 10min intervals during exercise | No |
