Children maintain cardiac output in heat via heart rate compensation; extends adult physiology to preadolescents but leaves open clinical translation.
How does ambient temperature affect cardiac output and its determinants during exercise in 10- to 11-year-old children?
In 10- to 11-year-old children, exercising in high ambient temperatures (40°C) causes a compensatory increase in heart rate and decrease in stroke volume to maintain cardiac output, similar to the physiological response seen in adults.
Tetsuo Katsuura (1985) studied this question.
