Abstract

The authors have previously described thermoregulatory responses of severely burned children during submaximal exercise in a thermoneutral environment. However, the thermoregulatory response of burned children to exercise in the heat is not well understood and could have important safety implications for rehabilitation. Children (n = 10) with >40% TBSA burns and nonburned children (n = 10) performed a 30-minute bout of treadmill exercise at 75% of their peak aerobic power in a heated environment. Intestinal temperature, burned and unburned skin temperature, and heart rate were recorded pre-exercise, every 2 minutes during exercise, and during recovery. Three of the 10 burned children completed the exercise bout in the heat; however, all the nonburned children completed the 30-minute bout. One burned child reached a core body temperature >39°C at minute 23. Burned children had significantly higher core body temperature through the first 12 minutes of exercise compared with nonburned children. However, nine of 10 (90%) burned children did not become hyperthermic during exercise in the heat. Specific to this study, hyperthermia did not typically occur in burned children, relative to nonburned children. Whether this is due to an intolerance to exercise in the heat or to an inability to generate sufficient heat during exercise needs to be explored further.
