Resistance training increases muscle strength by pitting the
muscles against a weight or force, such as a dumbbell or theraband.
As the elastic band is stretched, the resistance increases.
This resistance provides a progressive stimulus to the muscle
to build strength and help increase muscle mass.
Elastic resistance training (ERT) can work single or multiple
joints at one time, making exercises more functional and efficient.
The greatest advantages of elastic resistance are its portability,
affordability, and versatility.
- Increased muscle strength, power, endurance and size.
- Increased bone density and strength.
- Reduced body fat.
- Increased muscle-to-fat ratio.
- Boosted metabolism (burning more kilojoules when at rest).
- Lowered heart rate and blood pressure after exercise (thought
to reduce the risk of heart disease).
- Improved balance and stability.
- Enhanced performance of everyday tasks.
- Reduced risk of development of, and improvement of, medical
conditions - for example, diabetes and arthritis.
It is important to pay attention to safety and good form to
reduce the risk of injury. Consult with your doctor before
starting any new exercise program, especially if you are overweight,
over 40 years, have a pre-existing medical condition or haven't
exercised in a long time.
Unfortunately, elastic bands and tubing occasionally break.
While they are more subject to wear and tear than isotonic
weights, elastic resistance products have a longer clinical
life because of advances in manufacturing. Care must be taken
to inspect bands regularly and to avoid objects that can cause
damage. Be sure the bands are securely attached so they don't
snap back and cause injury. It's also difficult to quantify
the specific resistance of an elastic band compared with an
isotonic weight. For example, a particular band can't be equated
to the specific weight of a dumbbell; the force produced by
each band depends on how much it is stretched. Elastic bands
are not toys, so children should use them only with supervision.
