1. The body’s responses to Training/Exercise

2. Training
Cardiovascular fitness is how well the body is able to USE oxygen.
This has four stages :
1. how FAST you can breathe oxygen in to your lungs
2. how FAST you can transport oxygen to the muscles
3. how WELL your body USES it to provide energy to the muscles.
4. How quickly you recover from exercise

3. Types of Training
There are two main types of training to improve cardiovascular fitness.
Continuous training – exercise for 20 minutes or more, 65 – 85% of max. heart rate, 3-4 times per week.
Interval training – exercise at 85 – 100% effort, with longer intervals to recover. E.g. circuit training

4. Changes to your body through training
As your cardiovascular fitness improves, your
1. heart gets stronger
2. heart gets bigger
3. muscles take in oxygen better from the blood
4. muscles get better at using the oxygen

5. Changes to our body due to training
Short term changes – these are things that happen as soon as we start to exercise and stop when we stop exercising
Long term changes – these are more permanent changes to our bodies, that happen over time

6. Short term changes

7. Activity – Taking breathing rate
Normal/resting breathing rate – breaths per minute
In 15 seconds count how many times your chest rises
Multiple this number by 4 to get the answer
How do you think this would change with exercise???

8. Activity – Taking Heart Rate
Normal/resting heart – 70 beats per minute
To measure HR put 2 fingers on the neck (carotid pulse) count how many beats in 10 seconds x 6 =???
Take resting Heart rate
Perform 10 step ups on your chair
Take heart rate directly after exercise
Take heart rate 1 after exercise
What has happened to your heart rate??

9. Long term changes
