Lesson 1: Heart Rate and the Talk Test

• How do muscles help us move?
• Why is recovery important for technique?

Cardiovascular system

The heart and blood vessels that circulate blood throughout the body.

Heart rate

The number of times the heart beats in one minute.

Talk test

An effort check based on how comfortably you can speak during activity.

Your heart circulates blood that delivers oxygen and nutrients. During activity, working muscles usually need more oxygen, so heart rate and breathing increase. To estimate pulse, lightly place two fingers on the thumb side of your wrist; never press your neck. Count for 15 seconds and multiply by four. Short counts are only estimates, especially when the heart rate is changing. If you cannot find a pulse, use breathing and the talk test. We will not prescribe heart-rate targets or compare classmates. Health conditions, medication, and stress can affect heart rate, so follow your individual plan.

1. Sit quietly, then model gentle wrist placement using index and middle fingers.
2. Count pulse for 15 seconds with a timer and demonstrate multiplication by four.
3. Walk or roll for one minute while speaking a full sentence.
4. March for one minute, repeat the talk check, then slow down and recover.

• A brisk walk often raises heart rate above a quiet seated reading.
• Athletes can use the talk test when they do not have a monitor.

• Why does heart rate usually increase with exercise?
• What can you use if you cannot find a pulse?
• Why should we avoid comparing pulse numbers?

Privately record pre-activity and recovery observations without ranking results.

Mark a broad walking loop and a rest area with room for personal observation.

• Use comfortable effort; no maximum test.
• Keep observations private and do not rank heart rates.
• If speaking becomes difficult, slow down; report unusual symptoms immediately.

1. Rest quietly for two minutes and note breathing or an optional wrist-pulse estimate.
2. Walk or roll for two minutes and check speaking comfort.
3. March or gently jog for one minute only if comfortable.
4. Pause safely outside the lane and note observations, acknowledging pulse may already be slowing.
5. Recover with easy movement for two minutes and compare.
6. Discuss why personal observations, not a class target number, guide effort.

Model a pulse count and a talk check, then show choosing a slower pace.

• Keep at least an arm’s length between students and use marked travel lanes.
• Use controlled effort, not an all-out race; water and rest are available.
• Stop and tell the teacher about pain, dizziness, chest discomfort, or unusual breathing difficulty. Follow individual health plans.
• Wrist pulse only, light pressure; never use neck pressure or breath-holding.

Seated rhythmic movement, walking only, extended recovery, or breathing observations instead of pulse.

Explain measurement limitations and factors besides exercise that affect pulse.

Check that each student explains one cardiovascular response and selects effort safely using the talk test.

• Stay inside the coned boundary.
• Take turns and share equipment.
• Include anyone who wants to join.
• Teacher circulates and keeps eyes on all groups.
• Water available throughout.

• Walk or roll slowly for 2 minutes until breathing is comfortable.
• Supported calf stretch: 15–20 seconds each side, without bouncing.
• Gentle cross-body shoulder stretch: 15 seconds each arm.
• Take three relaxed breaths; drink water.
