Physical Education

A .........................................................
We do this after physical exercise. The idea is to slow down our heartbeat and breathing. It also helps us prevent certain problems after intense exercising. A good way to do this is by running very slowly and then stretching gently.
B .........................................................
This means exercise with oxygen. The body has enough oxygen to do this type of activity for long periods. The exercise is gentle. An example of this type of exercise is swimming slowly for 30 minutes.
C .........................................................
This means exercise without oxygen. The body has not got enough oxygen to do this type of activity for long periods. An example of this type of exercise is running 100 metres as fast as possible.
D .........................................................
This is the number of times your heart beats in a minute. Your resting heart rate is your minimum heart rate when you are relaxed and doing nothing. Your maximum heart rate is the top speed of your heart when you are doing exercise.
E .........................................................
We do this before physical exercise. The idea is to make your muscles ready, to gradually make your heart go faster, and to make your muscles and joints more flexible. Stretching and slow, gentle running can help.
