Hemodynamic and thermal aspects of prolonged intermittent exercise.

Abstract

9 young normal subjects were studied during two types of prolonged intermittent exercise requiring periods of heavy work (12 min at 80%\(\dot V_{O_2 }\) max.) alternating with intervening rest periods (for 18 min) in first type and light work (18 min about 40%\(\dot V_{O_2 }\) max.) in second type. In a third experiment, heavy exercise was repeated after 1 hr of rest and followed by light exercise. Hemodynamic variables and body temperature (oesophageal) were measured sequentially.
