Title: Heart rate and blood pressure Post by: mccaski95 on Aug 30, 2014 Explain the relationship between HR/ BP and intensity
Title: Re: Heart rate and blood pressure Post by: tduplantis on Aug 30, 2014 During low-intensity exercises, the heart beats well below its maximum rate. As exercise intensity increases, the heart rate moves closer to its maximum rate. Low-intensity exercises raise the heart rate to 40 to 50 percent of an individual’s MHR. Moderate-intensity exercises increase the heart rate to 50 to 70 percent of the MHR, while vigorous-intensity exercises elevate the heart rate to 70 to 80 percent of the MHR.

Blood pressure= Cardiac output X Systemic Vascular Resistance (afterload) So, if HR increases, BP increases. |
