Isometric Exercise Introduced
Isometric exercises by definition are those in which a
force is applied to a resistant object. They have a part
to play in a number of programmes for muscle strengthening.
A typical example is pushing against a brick wall. Although
there is a build up of tension in the muscles there is no
actual movement.
To increase strength it is necessary to maintain a position
in any one exercise for between 6 to 8 seconds. The exercise
should then be repeated 5 to 10 times, each time ensuring
maximum muscular contraction.
A number of important points regarding isometric exercise
need to be emphasised:
- Any one isometric exercise will only increase muscle
strength at one joint angle. To strengthen the other joint
positions requires repetition of further corresponding
exercises.
- Isometric exercises on their own are not recommended
for strength training. They must only form part of a complete
exercise programme.
- If you suffer from heart disease or raised blood pressure
you should stay clear of isometric training. During muscular
contractions in this form of exercise, blood pressure
can rise quite profoundly.
