Cardiovascular Fitness:  Heart Rate (HR) The number of times the heart beats each  minute (bpm) Changes over the lifespan Fetal HR is rapid and irregular Birth HR is below fetal level with periods of  bradycardia (slow heart rate – HR <60 bpm) 120- 140 bpm

Cardiovascular Fitness:  Heart Rate There is a decline in HR  with age Researchers believe the  decline in HR with age is  due to a decrease in  myocardial (heart)  sensitivity to  catecholamines (functions  as neurotransmitters and/ Changes over the lifespan -Overall, resting HR declines by  50% from birth to maturity -Adulthood -Average ~75-79 bpm

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
