PEPAB Norm Development (PEPABNRM).
Abstract
We developed a tool for predicting the treadmill speed at which to run subjects in order to elicit a desired percentage of their maximal aerobic capacity. We generated, tested and refined a pair of regression equations: one for submaximal aerobic exercise, the other for high-intensity anaerobic exercise. Within the limitations of using linear equations to elicit physiologic responses that are sometimes curvilinear, the equations are useful to researchers. Measures from an Actigraph activity monitor were validated against measures of heart rate and oxygen consumption (Vo2) while subjects performed a series of sedentary and physically challenging tasks. The Actigraph could be used to grossly estimate energy expenditure because of the relation of oxygen consumption to energy expenditure (5 kilocalories are expended for each liter of oxygen consumed). We compiled a normative data base (N=1 19) of all subjects tested to date; results are appropriate for comparison to other healthy, physically active populations. Lastly, we developed a computerized physical activity questionnaire (PAQ) to quantify average daily energy expenditure. The PAQ quantifies work, sleep and leisure time-activities over a one-week and/or one-year period. Although dependent on the accuracy of subject recall, the PAQ has proven to be a useful tool for estimating energy expenditure in over 60 subjects.
