Isometric Exercise Prevents Sports Injuries

By Rich Lauro MAT, MES

Isometric Exercise Explained

Isometric exercise and weight lifting are both muscle-strengthening resistance exercises.

While you may not be as familiar with the term isometric exercise, you probably are with weight lifting, which has many benefits including improved muscular strength, endurance, performance levels, and posture. It also reduces stress and the risk of injury.

Weight lifting will increase your metabolism to help you and improve your body image. Increased strength from this type exercises is what enables you to perform daily activities and to remain healthy.

What Is Isometric Exercise?

Isometric exercise is another form of resistance training that prevents injuries and speeds up rehabilitation from existing injuries. Isometric exercise involves muscular contractions, during which no shortening or lengthening of a muscle occurs.

In other words there is no movement. Instead, there is a constant and equal force or strain placed on the muscles.

It was once believed that if there was no joint movement, strength would develop only at the position in which the exercise is performed. In order to develop strength throughout the full range of motion, it was thought that resistance must be applied when the joint is in several positions.

This is not the case. If the muscle is strengthened in the shortened position with an isometric contraction, the strength will carry over throughout the entire muscles range.

Isometric exercising has the capability of producing a deep level of muscular development in a very short period of time. Isometric exercises are not as popular today because of all the new training techniques and products on the market today.
