Discussion Our results indicate that consumption of caffeinated coffee in comparison with decaffeinated coffee causes a slight rise in the mean change in pulse and respiration rate. However‚ the range bars of those that consumed caffeinated coffee and those that consumed decaffeinated coffee in The Mean Change in Pulse Rate graph overlap. Similarly the range bars in The Mean in Change in Respiration Rate graph overlap. This suggests that the mean change in pulse rate of decaffeinated and caffeinated
