PE: A Lesson on Heart Rate

What does the heart do in the body?

It pumps blood around the body to carry oxygen, nutrients, waste, and minerals.

What does the circulatory system do?

It moves nutrients and gases to cells and removes waste through the blood

What are the main parts of the circulatory system?

Heart, blood vessels, and blood

What is blood's job?

It carries oxygen, nutrients, waste, and other materials around the body.

What are blood vessels?

Pipes made of muscle and stretchy tissue that blood flows through.

What is heart rate?

The speed of your heartbeat, measured in beats per minute (BPM).

How do you measure your heart rate?

Count your pulse for 10 seconds and multiply by 6.

Where can you check your pulse?

Use your index and middle finger on your wrist below your thumb.

How do you find your maximum heart rate?

Subtract your age from 220.
Example: 220 - 15 = 205

What are the heart rate zones?

• Zone 1: 50–60% of Max HR

• Zone 2: 60–70%

• Zone 3: 70–80%

• Zone 4: 80–90%

• Zone 5: 90–100%

How do you find your resting heart rate?

1. Rest for at least 15 mins or do it right after waking up.

2. Count your pulse for 10 seconds.

3. Multiply by 6.

How do you calculate heart rate reserve?

Max HR – Resting HR = Heart Rate Reserve

Why do people track heart rate?

• To check fitness

• For specific training zones

• To spot health problems early

• To track progress with data
