Official title
Differences in Muscle Utilization, Tissue Pressure, Cognitive Performance, and Caloric Output Among Active and Passive Sitting Positions.
Overview
The study will compare cognitive capacity, muscle utilization patterns, soft tissue seated pressure and caloric output during four seated conditions: 1. passive sitting in a regular chair; 2. passive sitting in an exercise chair; 3. sitting in the exercise chair during active dynamic exercise; and, 4. sitting in the chair during active static exercise.
Interventions
- Behavioral Chaircise
A chair-based exercise program using a specialized chair with a foot lever that allows participants to lift their body weight.
Primary outcome measures
- Differences in cognitive performance among chair conditions as measured by the Psychomotor Vigilance Test in number of key depressions [Time frame: Approximately 3 minutes]
- Executive function among chair conditions as measured by the Stroop Test using words counted. [Time frame: Approximately 5 minutes.]
- Executive function among chair conditions as measured by the Stroop Test using error rate. [Time frame: Approximately 5 minutes.]
- Muscle activity among chair conditions using electromyography [Time frame: Approximately 45 minutes]
- Peak seated tissue pressure among chair conditions using a pressure sensitive mat [Time frame: Approximately 15 minutes]
- Metabolic cost of sitting among the chair conditions using a portable oxygen consumption unit [Time frame: Approximately 25 minutes]
Eligibility criteria
Inclusion criteria

- Use of prescription drugs or supplements that may affect cardiovascular or neuromuscular responses.
- Reported lack of sleep or stress that may affect physiological responses to exercise.
- Cardiovascular, respiratory, neurologic, balance, metabolic, or musculoskeletal conditions that could increase risk during exercise testing
