Summary

The purpose of this study is to look at how fast commercially available supplements containing carbohydrates can get into the bloodstream during repeated sprint cycles. This will build from a pervious study where the investigators tested these supplements on healthy participants during a resting oral glucose tolerance trial. The investigators will be testing three supplements, namely Voom Pocket Rocket, SIS Go Isotonic Energy Gel, and Maurten Gel 160. Each participant will complete all three conditions, consuming one of each supplement at random per condition. The study requires participation from male and female runners, cyclists and triathletes who are aged between 18-40.

Each visit will take approximately 1 hour, and three experimental visits per participant. The study will involve frequent blood sampling and the continuous monitoring of gas exchange (oxygen/carbon dioxide). Blood sampling via cannulation will be used to analyse the lactate, glucose, and electrolyte content of the blood. Gas exchange will measure the oxygen breathed in and carbon dioxide breathed out throughout the exercise.

The investigators plan to carry out the study on 10 participants who will be a mix of male and female runners, cyclists and triathletes.

Interventions

DIETARY_SUPPLEMENT

45 grams Voom Pocket Rocket Electro Energy

Participants will be required to consume 45 grams (in carbohydrates) of the Voom Pocket Rocket Electro Energy on one of the three experimental visits. Participants will have blood glucose, blood lactate, and electrolytes sampled throughout five 15-second repeated cycling intervals interspersed with 3 minutes active recovery. Gas exchange will also be monitored throughout the 1-hour study visit.

DIETARY_SUPPLEMENT

45 grams Maurten Gel 160

Participants will be required to consume 45 grams (in carbohydrates) of the Maurten Gel 160 on one of the three experimental visits. Participants will have blood glucose, blood lactate, and electrolytes sampled throughout five 15-second repeated cycling intervals interspersed with 3 minutes active recovery. Gas exchange will also be monitored throughout the 1-hour study visit.

DIETARY_SUPPLEMENT

45 grams SIS Go Isotonic Energy Gel

Participants will be required to consume 45 grams (in carbohydrates) of the SIS Go Isotonic Energy Gel on one of the three experimental visits. Participants will have blood glucose, blood lactate, and electrolytes sampled throughout five 15-second repeated cycling intervals interspersed with 3 minutes active recovery. Gas exchange will also be monitored throughout the 1-hour study visit.
