Denmark versus the NEtherlands

• vmbo g
• Leerjaar 4

Welcome

pairs:one danish, one dutch

sit down quietly, breathe slowly

Who are fittest? The Dutch or the Danish??

Lesson plan

• measure resting heart rate
• exercise
• measure heart rate over 5 minutes

change roles and repeat

Reasting heart rate

• sit down quietly 
• breathe evenly
• short pause after inhale and exhale

listen to explanation

Measure heart rate

• look for the two tendons in the wrist
• press index and middle finger down just beside these tendons (thumb side)
• vary pressure slowly until you feel a pulse
• count.

reverse roles and repeat

write down resting heart rates for both people (beats per minute)

How to measure after exercise

• open a stopwatch app that can record lap times (native app phone)
• observer will measure the pulse and say 'yes' every 20 heartbeats
• test subject will press 'lap' with every 'yes'.

Action!

• test subject will do the exercises on the next video (don't worry, we'll reverse roles) 
• test subject will press start and laps on stopwatch.
• observer will be ready to measure heart beats (say yes every 20 beats)

test subject 

• press start after exercise
• press lap when observer says yes

Reverse roles

• test subject will do the exercises on the next video 
• test subject will press start and laps on stopwatch.
• observer will be ready to measure heart beats (say yes every 20 beats)

Hoe goed is je conditie?

In de volgende dia's gaan we de resultaten bespreken. 

Alle vragen zijn anoniem, je klasgenoten kunnen op het bord niet zien wat jij hebt ingevuld.

who in your pair has the lowest resting heart rate??

The Dutch

The Danish

who in your pair has the highest heart rate directly after the exercise? (=shortest time needed for 20 beats)

The Dutch

The Danish

convert times to heartrate

20*60(s)/ lap time (s)

or

1200/lap time (s)

calculate 'recovery'

HR after 5 minutes rest / resting HR

who in your pair recovered fastest after the exercise? (lowest 'recovery')

The Dutch

The Danish

Good fitness

Low resting heart rate

Lower maximum heart rate

Fast adaptation to rest/activity

How is this possible?

Discuss health guidelines for exercise in your country. How much/ what type of exercise is good?

Netherlands

• At least one hour mild exercise each day (Walking, cycling, swimming)
• At least three times a week strength enhancing exercises
