Figure 1. Effects of Psychological Stress on the % Change in Heart Rate from
Resting Heart Rate. While competition seemed to have increased the change in
heart rate, a P-Value of 0.17 (n=10) is too high for us to reject Ho. Hence we must
The purpose of this study was to investigate if psychological stress or
anxiety can significantly alter heart rate and/or mean arterial pressure.
If the introduction of psychological stress can significantly alter heart rate
