Active Versus Passive Sitting, Cognition and Energy

Purpose

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.

Conditions

  • Electromyography
  • Pressure Injury of Back

No Intervention
Passive Comparator: Traditional Chair 		Participant will sit in the traditional chair for the amount of time it takes them to read a scientific article.
Placebo Comparator
Passive Comparator: Exercise Chair 		Participant will sit in the exercise chair for the amount of time it takes them to read a scientific article.
  • Behavioral: Chaircise
    A chair-based exercise program using a specialized chair that allows participants to lift their body weight.
Experimental
Experimental: Dynamic Leg Exercise in Exercise Chair 		Participant will sit in the exercise chair for the amount of time it takes them to read a scientific article while actively pushing down and releasing the foot operated lever as many times as possible.
  • Behavioral: Chaircise + Dynamic Leg Exercise
    A chair-based exercise program performed using a specialized exercise chair equipped with a foot-operated lever. Participants repeatedly depress and release the foot-operated lever during the intervention period.
Experimental
Experimental: Static Leg Exercise in Exercise Chair 		Participant will sit in the exercise chair for the amount of time it takes them to read a scientific article while actively pushing down and holding the foot operated lever.
  • Behavioral: Chaircise + Static Leg Exercise
    A chair-based exercise program performed using a specialized exercise chair equipped with a foot-operated lever. Participants depress and maintain pressure on the foot-operated lever during the intervention period.
