About this trial
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.
Eligibility criteria

Adult (18-70)
Disqualifiers
Any current injury in the lower limb or trunk.
Use of prescription drugs or supplements that may affect cardiovascular or neuromuscular responses.

Treatments tested in this trial
Chaircise
BehavioralA chair-based exercise program using a specialized chair that allows participants to lift their body weight.
Chaircise + Dynamic Leg Exercise
BehavioralA 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.
Chaircise + Static Leg Exercise
BehavioralA 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.

Trial outcomes
Primary outcomes
1
Differences in cognitive performance among chair conditions as measured by the Psychomotor Vigilance Test in number of key depressions
Cognitive performance will be assessed using the 3-minute Psychomotor Vigilance Test (PVT). During the test, participants will press the space bar as quickly as possible in response to the appearance of a visual stimulus on a computer screen. Performance will be measured as the total number of valid responses recorded during the test. Higher values indicate greater alertness, sustained attention, and reaction speed.
Time frame
Approximately 3 minutes2
Executive function among chair conditions as measured by the Stroop Test using words counted.
Executive function will be assessed using the Stroop Test, a cognitive task requiring participants to respond to color word stimuli. The outcome will be measured by total words counted, reported as the number of words.
Time frame
Approximately 5 minutes.3
Executive function among chair conditions as measured by the Stroop Test using error rate.
Executive function will be assessed using the Stroop Test, a cognitive task requiring participants to respond to color word stimuli. The outcome will be measured by error rate, reported as the percentage of errors.
Time frame
Approximately 5 minutes.4
Muscle activity among chair conditions using electromyography
Muscle activity will be assessed using surface electromyography (EMG). Muscle activation will be quantified as EMG amplitude, measured in microvolts (µV) from EMG recordings. Higher values indicate greater muscle activity.
