NCT02118662

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (4)

  • Heart rate

    Cross-sectional; single visit

  • Workload (watts) during seated cycling condition

    Cross-sectional; single visit

  • Speed during treadmill walking condition

    Cross-sectional; single visit

  • Typing accuracy

    Cross-sectional, single visit

Female Cohort

EXPERIMENTAL

Eight femalel participants per cohort will complete the following: Energy Expenditure during seated in an office chair during normal rest. Energy Expenditure during seated and typing. Energy Expenditure during Treadmill walking work condition. Energy Expenditure during cycling work condition

Other: Energy Expenditure during seated in an office chairOther: Energy Expenditure during seated and typingOther: Energy Expenditure during Treadmill walking work conditionOther: Energy Expenditure during cycling work condition

Interventions

You will first rest motionless in a chair for 20 minutes. You will complete the working conditions for 15 minutes each at your own self-selected level of effort. A rest period of 5 minutes will be given between each condition. During the working conditions, you will be asked to retype a displayed standard set of text.

You may qualify if:

  • You are a full-time employee at the Pennington Biomedical Research Center
  • You are between 21 and 65 years of age
  • You previously participated in the Pennington Biomedical Research Center's Worker's Acceptability of a Prototype Integrated and Interactive Pedal Desk study (WAPD study)

  • You are pregnant or lactating
  • You have high blood pressure (greater than 159 mmHg systolic or 99 mmHg diastolic).
  • You use tobacco or other nicotine products
  • You have a medical condition or take medications that influence heart rate or metabolic rate (for example - beta blockers, antihistamines, anti-depressants, diuretics, thyroid medications).
  • You have physical limitations that prevent performance of pedal motions or normal walking. You have any previous history of, or clinical symptoms or signs of, cardiovascular disease, stroke or transient ischemic attacks (TIAs), chest pain, unusual shortness of breath during physical activity, severe ankle edema (swelling), or intermittent claudication (pain caused by lack of blood flow during physical activity).
