Active Versus Passive Sitting, Cognition and Energy
Differences in Muscle Utilization, Tissue Pressure, Cognitive Performance, and Caloric Output Among Active and Passive Sitting Positions.
The study will compare cognitive capacity, muscle utilization patterns, soft tissue seated pressure and caloric output during four seated conditions:
- passive sitting in a regular chair;
- passive sitting in an exercise chair;
- sitting in the exercise chair during active dynamic exercise; and,
- sitting in the chair during active static exercise.

Differences in cognitive performance among chair conditions as measured by the Psychomotor Vigilance Test in number of key depressions
Zeitfenster: Approximately 3 minutes
|
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.
|
Approximately 3 minutes
|
|
Executive function among chair conditions as measured by the Stroop Test using words counted.
Zeitfenster: Approximately 5 minutes.
|
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.
|
Approximately 5 minutes.
|
|
Executive function among chair conditions as measured by the Stroop Test using error rate.
Zeitfenster: Approximately 5 minutes.
|
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.
|
Approximately 5 minutes.
|
|
Muscle activity among chair conditions using electromyography
Zeitfenster: Approximately 45 minutes
|
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.
|
Approximately 45 minutes
|
|
Peak seated tissue pressure among chair conditions using a pressure sensitive mat
Zeitfenster: Approximately 15 minutes
|
Seated tissue pressure will be assessed using a pressure-sensitive mat placed on the seat surface of each chair.
Peak pressure will be recorded to quantify the highest pressure exerted at the seating interface during each chair condition, measured in kilopascals.
Higher values indicate greater localized pressure on seated tissues.
|
Approximately 15 minutes
|
|
Metabolic cost of sitting among the chair conditions using a portable oxygen consumption unit
Zeitfenster: Approximately 25 minutes
|
Metabolic cost during sitting will be assessed under each chair condition using a portable indirect calorimetry device.
Participants will wear a facemask that measures oxygen consumption (VO₂) and carbon dioxide production (VCO₂).
These measurements will be used to estimate energy expenditure during the sitting period.
Higher values indicate greater metabolic cost.

Approximately 25 minutes
