Prediction of the aerobic demand of walking in children.Med. Sci. Sports Exerc., Vol. 34, No. 12, pp. 2097–2102, 2002. Purpose: The purpose of this study was to develop a generalized equation to predict V u O2 during level treadmill walking in young boys and girls. Methods: On an annual basis from ages 6 to 10, 23 able-bodied children (14 girls, 9 boys) completed six 5-min walking bouts at speeds ranging from 40.2 to 107.2 m·min 1 . Before testing, each child received 60 min of treadmill walking practice. During the last 2 min of each walking trial, a 2-min sample of expired gas was collected in a meteorological balloon and analyzed to determine V u O2. Results: Stepwise regression analyses indicated that the following equation was best suited to predict walking V u O2 :V u O2 24.852 0.003214 (walking speed in m·min 1 ) 2 0.995 (age in yr) 0.263 (walking speed); R 0.95; SEE 1.74 mL·kg 1 ·min 1 . Bland-Altman analysis revealed that 95% of the differences between actual and predicted V u O2 values fell within a range of 3.39 to 3.43 mL·kg 1 ·min 1 . Conclusion: We conclude that V u O2 during level treadmill walking can |
