Outcome Measures

Primary Outcomes (1)

  • Performance

    Performance will be measured by time required to complete a 2.6 mile time-trial immediately following marathon simulation

    10-15 minutes

Secondary Outcomes (5)

  • Ratings of gastrointestinal (GI) experiences

    Throughout experimental protocol for 1.5 - 2 hours

  • Blood Glucose Concentration

    Throughout experimental protocol for 1.5 - 2 hours

  • Blood Lactate Concentration

    Throughout experimental protocol for 1.5 - 2 hours

  • Core Temperature

    Throughout experimental protocol for 1.5 - 2 hours

  • Rated Perceived Exertion (RPE)

    Throughout experimental protocol for 1.5 - 2 hours

Study Arms (3)

Carbohydrate Dose: 0 grams carbohydrate

EXPERIMENTAL

Participants will be randomly selected, in a cross-over fashion, to ingest 0 grams/hour, 30 grams/ hour, or 60 grams/ hour of carbohydrate beverage throughout each experimental trial.

Other: Carbohydrate dosing

Carbohydrate Dose: 30 grams carbohydrate

EXPERIMENTAL

Participants will be randomly selected, in a cross-over fashion, to ingest 0 grams/hour, 30 grams/ hour, or 60 grams/ hour of carbohydrate beverage throughout each experimental trial.

Other: Carbohydrate dosing

Carbohydrate Dose: 60 grams carbohydrate

EXPERIMENTAL

Participants will be randomly selected, in a cross-over fashion, to ingest 0 grams/hour, 30 grams/ hour, or 60 grams/ hour of carbohydrate beverage throughout each experimental trial.

Other: Carbohydrate dosing
