Overview
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 Description
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.

Outcomes
Primary Outcomes
Physiological Strain Index (PSI)
Time Frame: During 2-hour exercise session
The PSI is an index that combines heart rate and core body temperatures with equal weights into an index from 0 to 10+. PSI will be calculated according to Moran et al. (1998) from measures of heart rate and core body temperature.
Secondary Outcomes
- Continuous Glucose Monitoring(24 hours)
- Perceived Exertion Scale(During 2-hour exercise session)
- Self Perception Scales(During 2-hour exercise session)
- Metabolic Flexibility(24 hours)
- Feeling Scale(During 2-hour exercise session)
- Profile of Mood States (POMS) Questionnaire(During 2-hour exercise session)
- Motivation(During 2-hour exercise session)
- Thermal Sensation Scale(During 2-hour exercise session)
