Clinical Trial Summary

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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.	Cross-sectional; single visit
Secondary	Heart rate	A heart rate monitor will be fastened around their chest using an elastic strap.	Cross-sectional; single visit
Secondary	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.	Cross-sectional; single visit
Secondary	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.	Cross-sectional; single visit
Secondary	Typing accuracy		Cross-sectional, single visit
