Abstract

Objectives: The objective is to understand the walking energy expenditure of women in urban environments (i.e., over‐ground), using mass, velocity, gradient (incline and decline), and burden as predictors. In addition, we use an equation to determine the gradient associated with the minimum energy expenditure of walking. Methods: To do this, we assessed the volumetric consumption of oxygen (VO 2) of ten females (ages: 22–40 years) with a portable Cosmed K4b 2 device. Participants walked at three self‐selected, over‐ground velocities (slow, normal, and fast) on five gradients (0%, +/−7.5%, +/− 12.4%) in different urban community settings burdened (10 kg) and unburdened. We performed a multilinear regression controlling for repeated measures to determine the best predictive equation for VO 2. The first derivative of our equation was used to find the gradient for minimal VO 2. Results: Our equation explains 79% of the variation in VO 2 and indicates that over‐ground walking is similar to treadmill walking, except that the gradient associated with the minimal energy expenditure of walking is steeper (−11% to −20%) than that established from treadmill walking. Conclusions: Although our overall equation is an accurate predictor of VO 2 for all velocities, burden, incline, and decline in this group, further research needs to be conducted to examine kinetic, kinematic, and velocity interactions in over‐ground walking.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
