How does blood pressure respond to aerobic exercise?

Systolic blood pressure rises as cardiac output increases. Diastolic pressure stays about the same during aerobic exercise.

Why does a warm-up improve blood supply to the muscles from the first minute of a match?

The warm-up starts vascular shunting early, so arterioles to the working muscles are already dilated. More oxygenated blood reaches the muscles as soon as play begins.

Name the lifestyle choices that damage the cardiovascular system.

Physical inactivity, smoking and excess alcohol all damage the system. A diet high in saturated fat and salt and long-term stress do so too.

How does heart rate respond to a warm-up?

Key term

Questions from this subtopic

Each one with the model answer underneath.

1
How does heart rate respond to a warm-up?
Model answer
Heart rate rises gradually during a warm-up. The heart then starts the main activity already delivering more oxygenated blood.
2
How does stroke volume respond as exercise intensity rises?
Model answer
Stroke volume rises with intensity and then plateaus at around 40–60% of maximum effort. Greater venous return fills the ventricles more, so they contract more forcefully.
3
An untrained student exercising maximally has a stroke volume of 120 mL and a heart rate of 180 bpm. Calculate the cardiac output.
Model answer
The cardiac output is 21.6 L min⁻¹. Stroke volume × heart rate = 120 mL × 180 bpm = 21,600 mL min⁻¹.
4
How does blood pressure respond to aerobic exercise?
Model answer
Systolic blood pressure rises as cardiac output increases. Diastolic pressure stays about the same during aerobic exercise.
5
Why does a warm-up improve blood supply to the muscles from the first minute of a match?
Model answer
The warm-up starts vascular shunting early, so arterioles to the working muscles are already dilated. More oxygenated blood reaches the muscles as soon as play begins.
