A research team from the department of cardiology at the Maxima Medical Center in Veldhoven, the Netherlands, investigated if athletes with abnormal exercise testing results and without obstructive coronary artery disease showed signs of a attenuated stroke volume response using cardiopulmonary exercise testing parameters.
The O2 pulse/workrate ratio beyond anaerobic threshold in athletes with abnormal exercise testing results was lower than that in athletes with normal exercise testing results. The V'O2/workrate ratio was also lower in athletes with abnormal exercise testing results. Furthermore, these athletes showed a greater increase in heart rate in the last 2 minutes of exercise.
