The Effects of an Acute Dose of a Betalain-rich Concentrate on Repeated-sprint Cycling Performance and Recovery.
(BET_RSE)
What this study is about
Betalains have well-known antioxidant and anti-inflammatory properties. Recent investigations examining the effects of a betalain-rich concentrate (BRC) on exercise and recovery performance show promise of BRC as an ergogenic aid. To date, no study has examined the effects of a single dose of a BRC on supramaximal performance and recovery.
View original scientific description
Betalains have well-known antioxidant and anti-inflammatory properties. Recent investigations examining the effects of a betalain-rich concentrate (BRC) on exercise and recovery performance show promise of BRC as an ergogenic aid. To date, no study has examined the effects of a single dose of a BRC on supramaximal performance and recovery. Therefore, the purpose of this study is to examine the effects of an acute dose of BRC on repeated-sprint cycling performance and recovery.
Interventions
DIETARY_SUPPLEMENT
Betalain-rich concentrate (AltRed)
A single dose of 100 mg (2 x 50 mg) 120 min before exhaustive exercise. Supplement instructions: All treatments will be administered in similar capsules (smell, color, and size) to ensure both the participants and researcher are blinded to the treatment. All treatments will be administered in an opaque lidded container. The participants will be instructed to close their eyes and carefully open the container, keeping their heads forward. They will be asked to place the container to their lips, tipping the container to pour the contents into their mouth. Immediately after, they will be instructed to drink water to help them swallow the pill and instructed not to chew or manipulate the pill inside their mouth.
OTHER
Placebo
A single dose (2 x empty capsules) 120 min before exhaustive exercise. Supplement instructions: All treatments will be administered in similar capsules (smell, color, and size) to ensure both the participants and researcher are blinded to the treatment. All treatments will be administered in an opaque lidded container. The participants will be instructed to close their eyes and carefully open the container, keeping their heads forward. They will be asked to place the container to their lips, tipping the container to pour the contents into their mouth. Immediately after, they will be instructed to drink water to help them swallow the pill and instructed not to chew or manipulate the pill inside their mouth.
Primary outcome measures
Repeated Sprint Performance
Time frame: Each data point will be assessed immediately after each Wingate sprint
Absolute and relative measures of peak, average, and minimum power (Watts). Also, the time to peak power and average power during the first and second half of each 30 s sprint.
Repeated Sprint Performance
Time frame: Each data point will be assessed immediately after each Wingate sprint
Fatigue index (%)

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
