Type A behavior, aerobic power, and cardiovascular recovery from a psychosocial stressor.

ABSTRACT

Fifty-six male university students were tested for actual aerobic power and Type A behavior (Form T of the Jenkins Activity Survey) before performing the Stroop Color-Word Interference Test. Neither fitness nor Type A was related to magnitude of heart rate (HR) increase, and only Type A was related to speed of recovery following the test, with Type As being slower to return to baseline HR levels than Type Bs. These results are discussed in terms of the need to consider factors that mediate speed of recovery from stress.
