The said findings indicated the followings: high intensity intermittent exercising would not cause the loss of homeostasis of the immune system as a result of the deviation of Th1/Th2 of high blood pressure sufferers; both the two ways of exercising could significantly lower the systolic pressure of high blood pressure sufferers, but the influence of continuous aerobic exercising on the pulse pressure was not significant, while high intensity intermit-tent aerobic exercising could effectively improve the pulse pressure of high blood pressure sufferers. It is feasible and effective for high blood pressure sufferers to do higher intensity intermittent exercises. |
