(2010) was cross-validated using 30 subjects consisting of 10 normal weight walkers, 10 overweight walkers, and 10 distance runners. Gender was balanced across sub-groups. Participants walked or ran for 5 minutes at their preferred pace. Preferred walking pace was determined by six timed 50-ft trials and preferred running pace by the runner's typical training pace. Energy expenditure (EE) was determined via indirect calorimetry and reported in absolute units (kcal), and corrected to a mile distance. Body composition was assessed via DXA. EE per mile was predicted using the Loftin, et al. (2010) equation. The equation [Kcal = mass (kg) x 0.789 ? gender (men=1, women=2) x 7.634 + 51.109; R2 = 0.632, SEE = 10.9 kcal/mile] yielded a mean of 99.7 ± 10.9 kcal/mile which was significantly different (p < 0.05) than the measured mean of the cross-validation group (107.8 ± 15.5 kcal/mile). However, the mean was within the standard error of the estimate of the original equation. Further analysis included a Chow test which yielded no significant differences between regression coefficients of the original equation and the cross-validation (CV) group [Kcal = mass (kg) x 0.825 ? gender (men=1, women=2) x 1.687 + 47.6; R2 = 0.625, SEE = 9.82 kcal/mile] equation. Also, absolute EE per mile for the CV group was similar across sub-groups. It appears the Loftin, et al. regression equation is useful for exercise prescription in that it allows for the prediction of EE for either walking or running a mile in normal weight and overweight adults.","abstract_html":"An equation recently published by Loftin, et al.
