Question
Define systolic blood pressure.
Predict the effect of a 100 m sprint on a runner’s systolic and diastolic blood pressure.
Markscheme
the force exerted by blood on arterial walls during ventricular contraction ✔
[1]
increase in systolic blood pressure ✔
no change/slight decrease in diastolic blood pressure ✔
[2]
Examiners report
While many understood what systolic pressure was, many gave incomplete answers or confused systolic and atrial pressure.
Most understood that systolic goes up but several thought that diastolic also increased. Many candidates merely stated that diastolic decreases, without mentioning by how much. Some mentioned that diastolic remains the same.
