Why the study?
Does aerobic conditioning lower heart rate and T-wave amplitude responses to a repeated psychological stressor in males?
Population
30 males, divided into aerobically conditioned (n = 15) and unconditioned subjects (n = 15)
Comparison
Aerobic conditioning (trained status) vs Unconditioned status
Design
Cross-sectional

Aerobic conditioning was associated with lower absolute HR responses to repeated stress; leaves open effects on relative HR and T-wave amplitude and requires prospective trials.
Does aerobic conditioning lower heart rate and T-wave amplitude responses to a repeated psychological stressor in males?
Aerobically trained males exhibit lower absolute heart rate responses during and after repeated psychological stress compared to untrained males.
Boutcher et al. (1993) studied this question.
