title: Prediction of maximal aerobic capacity in severely burned children.
abstract: BACKGROUND
  Maximal oxygen uptake (VO₂ peak) is an indicator of cardiorespiratory fitness, but requires expensive equipment and a relatively high technical skill level.
  
  
  OBJECTIVE
  The aim of this study is to provide a formula for estimating VO₂ peak in burned children, using information obtained without expensive equipment.
  
  
  METHODS
  Children, with ≥ 40% total surface area burned (TBSA), underwent a modified Bruce treadmill test to assess VO(2) peak at 6 months after injury. We recorded gender, age, %TBSA, %3rd degree burn, height, weight, treadmill time, maximal speed, maximal grade, and peak heart rate, and applied McHenry's select algorithm to extract important independent variables and Robust multiple regression to establish prediction equations.
  
  
  RESULTS
  42 children; 7-17 years old were tested. Robust multiple regression model provided the equation: VO₂ =10.33-0.62 × age (years)+1.88 × treadmill time (min)+2.3 (gender; females = 0, males = 1). The correlation between measured and estimated VO₂ peak was R = 0.80. We then validated the equation with a group of 33 burned children, which yielded a correlation between measured and estimated VO₂ peak of R = 0.79.
  
  
  CONCLUSIONS
  Using only a treadmill and easily gathered information, VO₂ peak can be estimated in children with burns.
