title: Anterotracheal temperature during and after exercise in the guinea pig.
abstract: We measured the temperature in the anterotracheal region of the guinea pig during and after various intensities of exercise (from 20 to 100 m/3 min). The temperature decreased during exercise, and the maximal drop of the temperature increased with increasing intensity of exercise up to a speed of 80 m/3 min. When the exercise was discontinued, the temperature initially fell rapidly, then rose progressively to equal or exceed the preexercise value. The changes in temperature were similar among 5 animals. These findings suggest that the tracheal wall temperature changes during and after exercise relative to the intensity of exercise. Using this method in guinea pigs may provide more information about the pathophysiology of exercise-induced asthma.
