8.1 The effect of training
The demands of today's lifestyle in modern societies are not enough to remain in good
conditional shape. Cardiovascular diseases are still the most common cause of
death.
This fact should make cardiovascular training a top priority.
All training activities during which the heart rate increases for 15 to 20 minutes or
longer are called "aerobic".
8.2 Cardiovascular training
To get the most benefit out of your training, you should be familiar with some training
principles.
Your fitness depends to a great extent on your body's ability to provide your muscles
with oxygen. Oxygen is the key to the energy stored in the muscles.
Let us take a closer look at some of the factors crucial to this process: The heart and
its role as a complex pump is responsible for the smooth blood flow in the body.
Regular aerobic training will increase the heart's stroke volume, i.e. it will transport
more blood through your body with every beat. Accordingly, the heart works more
efficiently not only during training, but also at rest.
When oxygen enters the lungs, it will be mixed with blood in tiny "air sacs", the socalled
alveoli. Regular aerobic training will improve the efficiency of the alveoli and thus,
more oxygen will enter the bloodstream and be transported to the muscles.
Haemoglobin is the substance of the blood that absorbs the oxygen. Regular aerobic
training will increase the part of the haemoglobin in the blood, which in turn allows
your muscles to be better supplied with oxygen.
It is a fact that heart diseases are much less common in people who train regularly.
Overall, it may be said that regular training improves the amount of oxygen supplied
to the muscles and the risk of heart disease decreases. For this reason, ERGO-FIT
cardio exercise machines are used in both gyms and rehabilitation centres.
