Q1.
Scientists investigated the effects of water temperature on the heart rate of swimmers.
Two groups of volunteers were asked to repeat the same swim at three different temperatures.
• Group 1 volunteers were asked to swim 100 m as quickly as they could.
• Group 2 volunteers were asked to swim continuously for 30 minutes.
The scientists recorded the highest heart rate for each swimmer during each swim.
Their mean results are shown in the following figure.

(b) After reading the scientists’ report, a member of a swimming club stated that “the report
shows that swimming flat out is better for you than swimming for a length of time.”
Evaluate this statement.

(b) Scientists investigated the effect of diabetes on the control of heart rate in response to
changes in blood pressure in rats.
The scientists found the mean changes in heart rates of healthy rats and rats with diabetes in
response to rises or falls in blood pressure.
The diagram shows their results in the form they were presented.
