Chapter 13, Problem 32E
Jane trained for a marathon for 6 months. Her resting heart rate is 50 beats/mm and her blood pressure is 105175 mm Hg. Jane’s roommate. Sue, watches a lot of TV and has a resting heart rate of 85 beats/mm and blood pressure of 135/85 mm Hg. Both women have the same resting cardiac output of 5.0 literslmiri. Determine the resting stroke volume and mean arterial pressure for each woman. Based on your findings, whose heart is beating more efficiently?

The end systolic volume from an individual’s heart was found to be 50 ml, the end diastolic volume was found to be 110 ml and the heart rate was 90 bpm. What is this individual’s stroke volume, ejection fraction and cardiac output (C.O)?
Group of answer choices
SV = 60 ml Ejection Fraction = 50% C.O = 3.4 l/min
SV = 110 ml Ejection Fraction = 52% C.O = 4.4 l/min
SV = 60 ml Ejection Fraction = 55% C.O = 5.4 l/min
SV = 160 ml Ejection Fraction = 70 % C.O = 6.4 l/min

- Describe how cardiac performance is measured in cardiac output. In your answer, be sure to describe the role of stroke volume (SV) and HR by defining each and discussing factors that influence SV in particular both during acute exercise and following chronic exercise training.arrow_forward1. Sue has a resting stroke volume of 72 ml/beat and an average resting heart rate of 70 beats/minute. What is her cardiac output (CO). Remember to include correct units in your answer. 2.Sue goes to the gym and after an initial warm-up, she increases her exercise level pushing herself to maximum.
