Proven Arm PRotection
Until now, no product has offered unrestricted elbow and shoulder support that has been proven to reduce dynamic arm stress that can lead to fatigue, pain, and overuse injuries. This revolutionary advancement in arm care is redefining arm protection in multiple sports nationwide and around the world.
The Kinetic Arm K2 sleeve is an essential accessory for tennis players, as well as athletes in racket sports like pickleball, racquetball, badminton, and squash. Designed to safeguard the elbow and shoulder from common overuse injuries associated with repetitive arm motions—such as tendonitis and tennis elbow.
Shoulder strains and tennis elbow, or lateral epicondylitis, are common overuse injuries in racket sports that can cause pain and setbacks. The Kinetic Arm helps by providing targeted support to both the elbow and shoulder, stabilizing the joints to optimize mechanics and reduce stress in active and passive ranges during swings. This dynamic stabilizing sleeve allows freedom of movement and has proven to to reduce dynamic stress that can lead to fatigue, pain and overuse injuries to the shoulder and elbow.
The Kinetic Arm K2 sleeve utilizes multi-patented MuscleWeb® activated stabilizing technology to provide adaptive support for both the elbow and shoulder during swings, without restriction. With strategically embedded polymers, it offers targeted, multi-directional support that activates in passive or high-stress positions. By wearing the K2 sleeve, players can offload strain from critical areas, promoting optimal movement mechanics and significantly reducing the risk of fatigue, pain, and overuse injuries.
The Kinetic Arm dynamic stabilizing sleeve features an embedded MuscleWeb® technology that gives responsive, targeted support to critcal areas of the arm during active and passive ranges. Wearing this external web of support helps reinforce the muscles, ligaments, and joints during dynamic arm movements without restriction, to help aid in protection, performance, recovery, and prevention.
MULTI-DIRECTIONAL SUPPORTIVE DESIGN
Front Shoulder Support
Embedded polymers overlay the front of the shoulder, providing essential supportive tension to stabilize the joint and reduce stress during passive ranges when strain is at its highest. This web of polymers helps to offload stress from the musculoskeletal system by preventing the arm from lagging behind as the trunk rotates during dynamic arm motions. By alleviating stress on the biceps tendon and labrum, this external layer of support helps protect the front of the shoulder, reducing the risk of common overuse injuries to the biceps tendon, labrum, and rotator cuff.
FULL ELBOW SUPPORT
Built-in polymers are strategically placed to reinforce the joint, ligaments, and forearm muscles. This targeted support is especially crucial for the medial elbow during external rotation and the late cocking phases of throwing, swinging, and serving. By stabilizing the elbow in passive ranges, where peak stress typically occurs, the sleeve helps to reduce torque and dynamic stress, minimizing the risk of common overuse injuries such as UCL, tendonitis, and tennis elbow.
BACK SHOULDER SUPPORT
Embedded polymers overlay the back of the shoulder, providing essential dual joint support and stabilization during force generation and arm deceleration. Acting as an active constraint, it minimizes joint stress by providing multi-directional support to the muscles and ligaments during dynamic arm movements. This polymer web design allows full range of motion while reinforcing the posterior shoulder to help offload stress by aiding in the eccentric control of the scapula and humerus, reducing distraction forces on the posterior shoulder and elbow, and delivering external support as muscles elongate.
INTELLIGENT DESIGN
DUAL JOINT SUPPORT
The K2 BioKinetic® Sleeve provides elbow and shoulder support that activates during passive, high-stress phases of swinging. Wearing dual joint support is essential during repetitive and explosive movements like swinging because these joints are closely interconnected. When one joint is stressed, the other absorbs part of the load, making both vulnerable to overuse injuries if not properly stabilized. Supporting both the elbow and shoulder helps maintain optimal mechanics, reduces strain, and prevents injuries such as tennis elbow and shoulder tendonitis.
NOTHING ELSE LIKE IT
The Kinetic Arm K2 BioKinetic® Sleeve stands apart from traditional arm supports by offering combined elbow and shoulder stabilization that has been scientifically proven to reduce dynamic arm stress while allowing for full, natural movement. Unlike standard sleeves, the K2 Sleeve uses its multi-patented MuscleWeb® Design to dynamically reinforce muscles, ligaments, and joints, ensuring safer ranges of motion and reducing overall arm stress.
With over 10 years of research and testing the Kinetic Arm dynamic arm stabilizers are backed by data and published research demonstrating their effectiveness in offloading dynamic arm stress. All studies have undergone scrutiny and have been validated by research and medical professionals.
