September 1, 1986Psychophysiology

No aerobic fitness level effect on heart rate was found, but there was greater T-wave amplitude attenuation in the low compared to the high aerobic fitness level group on hard trials.

Design

Cross-sectional

Overview

Higher fitness may blunt sympathetic reactivity to mental stress; cross-sectional data leave causality and practice implications open.

Structured PICO

Does high aerobic fitness level reduce phasic cardiac reactivity to psychological stress in males?

P
Population
24 males divided into high and low aerobic fitness level groups based on a standard physical fitness test
I
Intervention
High aerobic fitness level
C
Comparator
Low aerobic fitness level
O
Outcome
Heart rate and electrocardiographic T-wave amplitude responses during hard and easy versions of a mental arithmetic tasksurrogate

Enhanced aerobic fitness may reduce psychologically-elicited sympathetic cardiac reactivity, as evidenced by differences in T-wave amplitude attenuation during mental stress.
