Further study details as provided by University of Texas at Austin:

Primary Outcome Measures:
  • Improved Time Trial Performance [ Time Frame: After 20 min steady-state cycling ]
    Participants will cycle 20 min at increasing intensity: 8 min at 55% VO2max, 6 min at 65% VO2max, 6 min at 75% VO2max. The 20 km time trial consists of rolling hills.

Secondary Outcome Measures:
  • Improved work efficiency [ Time Frame: During 20 min steady-state cycling ]
    Expired gases will be collected and compared to expected VO2. Blood will be collected prior to treatment, prior to exercise and during each cycling intensity to analyze lactate accumulation.

Estimated Enrollment: 16
Study Start Date: October 2012
Estimated Study Completion Date: May 2013
Estimated Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Nitrate supplement with caffeine Dietary Supplement: Nitrate supplement with caffeine
Lozenge consisting of beetroot and 75 mg caffeine
