About this study

Official title: The Need for Speed: Comparing the Speed of Glucose Absorption During Repeated Sprint Cycling

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.

Being tested
45 grams Voom Pocket Rocket Electro Energy, 45 grams Maurten Gel 160, 45 grams SIS Go Isotonic Energy Gel

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 45 grams Voom Pocket Rocket Electro EnergyDietary supplement

    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.

  • 45 grams Maurten Gel 160Dietary supplement

    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.

  • 45 grams SIS Go Isotonic Energy GelDietary supplement

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Blood Glucose

    Frequent blood sampling for blood glucose (1ml after every stage of both sprint cycling and active recovery) followed by analysis in the Biosen Analyser

    Measured: Blood glucose measures will be taken 35 minutes after consuming the supplement(s) (baseline), after the 3 minute warmup, and then after every 15 second sprint and every 3 minute period of active recovery

  2. Blood Lactate

    Frequent blood sampling for blood lactate (1ml after every stage of both sprint cycling and active recovery) followed by analysis in the Biosen Analyser

    Measured: Blood lactate measures will be taken 35 minutes after consuming the supplement(s) (baseline), after the 3 minute warmup, and then after every 15 second sprint and every 3 minute period of active recovery

  3. Gas Exchange

    Gas exchange measured throughout each 20 minute exercise via a Cortex Metalyzer

    Measured: Gas exchange will be measured continuously throughout the 20 minutes of exercise, starting at the warmup

Secondary outcomes (3)

  1. Blood electrolyte content

    Frequent blood sampling for electrolyte concentrations of the blood (sodium, potassium, chloride, calcium) (1ml after every stage of both sprint cycling and active recovery) followed by analysis in the Biosen Analyser

    Measured: Blood electrolyte measures will be taken 35 minutes after consuming the supplement(s) (baseline), after the 3 minute warmup, and then after every 15 second sprint and every 3 minute period of active recovery

  2. Rate of Percieved exertion (RPE)

    Participants will report their RPE using the Borg Scale to report how hard they are finding the exercise. This will be done after the warm-up and after the final sprint.

    Measured: RPE will be measured at the end of the warmup and the end of the final sprint stage

  3. Gastrointestinal (GI) Discomfort Questionnaire

    Participants will complete a GI discomfort questionnaire 5 minutes before starting exercise and at the end of exercise

    Measured: GI Discomfort will be measured 5 minutes before and 5 minutes after exercise

Model description
This will be a double-blind randomised crossover design. There will be 1 group of participants who will complete all three conditions at random: Condition 1 - consume Voom Pocket Rocket. Condition 2 - consume SIS Isotonic Energy Gel. Condition 3 - consume Maurten Gel 160. Participants will consume each product 35 minutes before starting exercise. All participants will undergo the same exercise - 5 repeated sprint cycling (cycling against 0.075 kg/ kg body mass) intervals of 15 seconds interspersed with 3 minutes of active recovery. All participants will have the same measures taken - blood sampling for blood glucose, blood lactate, and electrolytes at the end of each sprint and period of active recovery, and monitoring of gas exchange throughout the exercise.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Blood Glucose (time frame: Blood glucose measures will be taken 35 minutes after consuming the supplement(s) (baseline), after the 3 minute warmup, and then after every 15 second sprint and every 3 minute period of active recovery). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06768333, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2025.
