About this study
The study is designed to measure the energy expenditure associated with a common office task (i.e., typing) while 1.) seated in an office chair, 2.) pedaling using a prototype pedal desk, and 3.) walking on a treadmill.
Read the detailed description
The anthropometrics will be measured first. The height and body weight will be collected by clinic staff in the clinic.
The metabolic testing of all conditions will take place in a real office setting. The participant will be fitted with a heart rate monitor fastened around their chest using an elastic strap. They will also be fitted with a portable metabolic system (COSMED). This unit fits around their waist and back, much like a backpack. The unit is attached to a face mask that fits over their mouth and nose and is secured by elastic straps which wrap around their head.
The participants will first rest motionless in a chair for 20 minutes. Following this, they will complete three different simulated working conditions by typing at a computer while 1) seated in an office chair, 2) seated pedaling while using a prototype pedal desk, and 3) walking on a treadmill. The order of testing for the seated pedaling and treadmill walking working conditions will be counterbalanced with participants randomly assigned to the two possible order permutations. They will complete the 3 working conditions for 15 minutes each at their own self-selected level of effort. A rest period of 5 minutes will be given between each condition. During the working conditions, they will be asked to retype a displayed standard set of text.

What is being measured
The primary outcome is the main question the study is designed to answer.
Energy Expenditure
Energy expenditure will be measured using a portable metabolic system while performing common office tasks or desk work while sitting, standing, and walking. The portable metabolic system consists of a small gas analysis unit and a battery positioned on the abdomen and mid-back, respectively. Respiratory gases are collected by mask that fits over the mouth and nose and analyzed by the unit. The mask does not restrict a participant's breathing, vision or line of sight.
Measured: Cross-sectional; single visit
Secondary outcomes (4)
Heart rate
A heart rate monitor will be fastened around their chest using an elastic strap.
Measured: Cross-sectional; single visit
Workload (watts) during seated cycling condition
Participants will be instructed to maintain their preferred pedaling rate during cycling for 10 minutes. Pedal force will be recoreded by specialized pedals.
Measured: Cross-sectional; single visit
Speed during treadmill walking condition
Participants will be instructed to maintain their preferred treadmill speed during treadmill walking for 10 minutes. Speed will be recoreded by someone outside the immediate study group.
Measured: Cross-sectional; single visit
Typing accuracy
Measured: Cross-sectional, single visit

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Energy Expenditure (time frame: Cross-sectional; single visit). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Sep 2022.
