The Effects of an Acute Dose of a Betalain-rich Concentrate on Repeated-sprint Cycling Performance and Recovery: A Randomized, Double-blind, Crossover, Placebo-control Study.
Drexel University
Summary
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.
Description
A minimum of 10 recreationally active men and women will be recruited from the Drexel University student population. All eligible participants will report to the laboratory for a total of three visits (one familiarization session, and two testing sessions). Each participant will be randomly assigned to receive the treatment or placebo in a counterbalanced fashion. Visit 1 will serve as a familiarization session, where all participants will perform the repeated-sprint exercise (RSE) protocol, and the countermovement jump (CMJ) to become acquainted with the exercises. In addition to testing fam…

Interventions
- Dietary SupplementBetalain-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.
