How does training affect the heart rate?
Your heart rate changes from minute to minute. It depends on whether you are standing up or
lying down, moving around or sitting still, stressed or relaxed. When you have been at rest for
a bit, the heartbeat settles down; this is your resting heart rate. Pulse is the oldest and easily
observable heart parameter. It is the regular expansion of an artery caused by the ejection
of blood into the arterial system by the contractions of the heart. Resting pulse for
teenagers is usually 75-100 beats per minute, adults 60-80 beats per minute and athletes
40-50 beats per minute.

1. Answer for the RQ. Can you see a trend? Why, why not.
2. When you are sick your heart works faster (1 Celsius-8-10 beats). Why?
3. High resting heart rate has been linked to atherosclerosis, sudden death, and an
increased risk of dying from cardiovascular disease. Why?
