Strength ball training involves both stability balls and medicine balls. Although the stability ball, also known as the Swiss, is evolving as a cutting edge exercise tool today, the use of a ball in exercise actually dates back to the 2nd Century A.D.
Todays stability ball was developed in the early 1960’s as a children's toy. It was then adopted by physiotherapists as a means of improving patient’s proprioception and balance. Strength and conditioning professionals and personal trainers often use stability balls in their programs.
Strength Ball Training is useful for all populations, as it can be easily adapted to meet a variety of needs and goals. Balls of various sizes, inflation densities, and loads, exercise variations, and the dynamic stabilizing load enable new users and veteran athletes alike to enjoy exercises appropriate for their skill levels.
There are numerous methods of progressing the level of difficulty when using the stability ball exercises.
Change the base of support:
By decreasing the base of support for a exercise, you can increase the challenge of balance. You can achieve this by increasing the inflation of the ball, which will result in a smaller base of the ball support. You can also change the base of support by removing an arm of lever from the ball or ground.
Change The length of the lever:
as you alter the length of your lever arm from short to long, you increase the difficulty of the exercise. An example would be Ab crunch medi ball throw:-
Throwing from the chest is easier than using a longer lever and throwing overhead. Your trunk can also be the lever arm between the floor and the balls contacts. a short rollout is easier than a longer rollout. Minor changes in body position can make a dramatic difference inlevel of difficulty by changing the co-ordination, effort or forced required.
Increase range of motion:
by increasing movements from small to a larger range, you can increase the difficulty of the exercise.
Speed of movement:
Changing the tempo of an exercise changes the result. Very slowly movements keep the muscle loaded under tension longer and help build strength and stability. Fast dynamic movements tend to build power. The tempo of movement also makes the exercise easier or more difficult. Most Experts suggest that moving faster is more difficult, but there is no general rule here. Some exercise done more quickly are much more difficult. Still other exercises done very slowly require much more strength and balance. Know that speed of movement alters the demands.
Add resistance:
You can increase the intensity of an exercise by adding some form of loaded resistance, such as a medicine ball, free weights, or resistance bands/tubing. Strength tubing needs to be long enough to accommodate whole-body moves, it also needs to be strong enough to offer enough resistance. It should come with a protective sleeve to make the tubing more durable.
Close your eyes:
by closing your eyes, you increase the proprioceptive demand in the body, flooding other sensors and receptors positioned to give feedback on changes to muscle, ligaments, ligaments, tendons, and joint position. removing visual feedback overloads your proprioceptive system, forcing those “minibrains” to work harder and improve. this adds a level of difficulty, but you should take caution. Some of the exercises will require spotting by a strength coach, trainer or training partner.
Sizing:
Most manufacturers of stability balls make sizing recommendations based on your height. one general rule that has been stated is that when you sit on the ball your thighs should be parallel to the floor. if they are below parallel level, you will be forced to use poor posture for many of the exercises.
In your fitness facility you should see a variety of different sized balls :
here is another size guide for personal use;
6’4 and taller = 65cm and 75cm balls
5’10 - 6’3 = 55 cm and 65cm Balls
5’9 and less = 45 and 55 cm balls
