NCT03294642

Brief Summary

This research study evaluates the feasibility and appropriateness of potatoes as an ergogenic aid in comparison to the currently promoted sports gels during a cycling challenge and time trial. Using a crossover design, trained cyclists will complete three separate cycling challenges and subsequent time trials in which they will consume either potatoes, commercially available sports gels, or water only.

Outcome Measures

Primary Outcomes (1)

  • Time trial performance measured in minutes

    Comparison of time trial performance times between potatoes and sports gel conditions to determine effectiveness of potatoes as an ergogenic aid.

Study Arms (3)

Trial 1

EXPERIMENTAL

Water Intervention: In one of the 3 cycling trials, participants will receive only water and no carbohydrate supplementation during the 2 hour cycling challenge.

Dietary Supplement: Water

Trial 2

EXPERIMENTAL

Carbohydrate Gel Intervention: In one of the 3 cycling trials, participants will receive carbohydrate supplementation in the form of commercially available gels (15g every 15 minutes) during the 2 hour cycling challenge.

Dietary Supplement: Carbohydrate Gel

Trial 3

EXPERIMENTAL

Potatoes Intervention: In one of the 3 cycling trials, participants will receive carbohydrate supplementation in the form of pureed russet potato (15g every 15 minutes) during the 2 hour cycling challenge.

Dietary Supplement: Potatoes

Interventions

PotatoesDIETARY_SUPPLEMENT

Pureed russet potatoes will be used as a carbohydrate supplement for participants during one of the three cycling challenges.

Trial 3
Carbohydrate GelDIETARY_SUPPLEMENT

Commercially available PowerBar PowerGel will be used for the carbohydrate gel condition during one of the three cycling challenges.

Trial 2
WaterDIETARY_SUPPLEMENT

Water will be used as a control during one of the three cycling challenges (participants will not receive any carbohydrate supplementation).
