Clinical Trial: The Pacing (Guided Vs Unguided) Strategies Study
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: The Impact of Real-Time Physiological Status Based Pacing Guidance on Physiological Strain for Exercising Humans
Brief Summary: The objectives of this study are to demonstrate that real time physiological status monitoring and the use of optimization techniques during exercise can have a positive impact on physiological status, and to collect metabolic flexibility profiles of young fit adults during rest and exercise.
Detailed Summary: This experiment aims to accomplish two goals: collect additional metabolic flexibility data with young fit adults in response to exercise; and demonstrate that automated pace guidance generated from real-time thermal-work strain monitoring and an optimized pacing policy will allow less stressful completion of a timed (60 minute) treadmill exercise of 5 miles. Each participant will undergo two treatments of first UNGUIDED followed by GUIDED exercise. The two exercise sessions will be conducted as part of a ~24 hour stay in an indirect calorimetry chamber.

Current Primary Outcome: Physiological Strain Index (PSI) [ Time Frame: During 2-hour exercise session ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Metabolic Flexibility [ Time Frame: 24 hours ]O2 utilization and CO2 production will be analyzed during each calorimeter stay and used to measure metabolic rate indirectly.
- Continuous Glucose Monitoring [ Time Frame: 24 hours ]Continuous glucose monitoring will be used to examine the effects of the exercise regime on blood glucose.
- Self Perception Scales [ Time Frame: During 2-hour exercise session ]Self perception scales will be used that measure mood state, perceived exertion, thermal sensation, physical stresses and motivation.
- Profile of Mood States (POMS) Questionnaire [ Time Frame: During 2-hour exercise session ]The POMS is an inventory of subjective mood states (McNair, Lorr and Droppleman, 1992).
- Thermal Sensation Scale [ Time Frame: During 2-hour exercise session ]Two thermal sensation scales (original and modified) will be used to assess the thermal sensation of volunteers.
- Perceived Exertion Scale [ Time Frame: During 2-hour exercise session ]The Borg (1970) rating of perceived exertion (RPE) will be used.
- Feeling Scale [ Time Frame: During 2-hour exercise session ]The feeling scale will be used as an affective valence measure of exercise.
- Motivation [ Time Frame: During 2-hour exercise session ]Question will be asked to assess motivation during each exercise session.
Original Secondary Outcome: Same as current
