Benefits/Uses

Helps develop the core body muscles by forcing the body to respond to the the instability of the ball.
Can be used in place of a chair to help maintain proper posture as it engages the abdominal and back muscles.
Develops strength in all planes of motion (frontal, sagittal, and transverse) which helps improve overall functional strength and decrases the chance of injury.

1) What is the right size stability ball?
If you were to only get one size I would recommend the size that allows you to sit on the ball and keep a 90 degree bend at the knees and hips. However, many exercises require different size Stability Balls in order to provide the proper intensity. An example of this is an abdominal stretch while lying on the ball: A bigger ball provides a more gentle stretch than a smaller ball.
2) Is a deflated ball more or less stable?
Although a deflated ball has more surface area contact with the ground, it is less stable due to the slow reaction forces with the body surface (e.g. the hands). When a ball is deflated, it is hard to find and maintain the center of mass under the body’s base of support, thus making it hard to balance.
3) Does one develop stability or balance when using the ball?
Exercises requiring less force develop balance, while exercises requiring more force develop stability. Stability is by far the most important component to develop with the stability ball. |
