al. 210), will remain the same. As noted by Lellamo (2001), one of the many reasons why heart rate increases at maximal intensity is the parasympathetic and sympathetic nervous system. As the nervous system responses to the high power of a certain exercise, nerve signals are sent to the motor cortex of the brain which then send stimuluses to the heart in order for the heart to supply oxygen to the muscles and for the muscles to work at a significant pace. Therefore, the purpose of this lab is to examine the heart rate and blood pressure respond to increasing intensity. It was hypothesized that heart rate and systolic blood pressure would increase with increasing intensity. While diastolic blood pressure will remain the
