This external reinforcement minimizes the risk of fatigue, pain, and overuse injuries, allowing athletes to maintain full range of motion and alleviate stress during repetitive arm actions.
The Kinetic Arm helps optimize mechanics by promoting safer anatomical ranges of motion, improving joint alignment, and stabilizing the elbow and shoulder to reduce dynamic arm stress. Its embedded MuscleWeb® design provides a web of support without restricting movement, reinforcing the arm and encouraging efficient movement patterns. In overhand throwing, where fatigue can cause the arm to lag behind during body rotation—leading to excess stress on the elbow, shoulder impingement, and strain on the labrum—the Kinetic Arm reinforces these vulnerable areas, helping athletes maintain better mechanics and safer ranges of motion. This makes it a valuable tool for athletes striving to protect their arms and enhance performance.
Because the Kinetic Arm helps to optimize mechanics and reduce arm stress it allows athletes to build strength and get more reps in with less fatigue and strain on their arm, so they can have a safer approach in gaining and sustaining velocity.
Athletes that have worn the Kinetic Arm have claimed it has helped them gain and sustain velocity over time, because they were able to train with higher intensity and safer progressions, because they have less arm stress and fatigue.
No, the Kinetic Arm brace does not restrict motion or alter your delivery. If you feel any restriction in range of motion, simply adjust the chest portion of the sleeve or loosen the strap slightly. This combined elbow and shoulder brace is designed to allow a full, unrestricted range of motion, providing dynamic support that synchronizes with your arm movements during activities like throwing and swinging.
No. Wearing the Kinetic Arm will not cause reliance or dependency.
Athletes are still be able to build strength and the necessary physical adaptations, because they still have to use their muscles to generate that force for that movement. In other words, the Kinetic Arm does not assist to move your arm for you.
There have been no signs or reports of muscle atrophy with long term use, because of the force generated that is required to move the arm during arm motions such as throwing, swinging, serving and hitting.
Peak stress happens in passive ranges during dynamic arm movements.
The Kinetic Arm is designed to give activated support to the elbow and shoulder in these ranges to help dampen arm stress.
If you are at all concerned about dependence or reliance, just use it on and off as a workload management tool especially on heavier workload or recovery days.
