Training the correct 90 degree elbow position when learning a new sport or correcting poor arm positions will not only improve game performance, but is vital to avoid future elbow injuries. When athletes throw, serve, drive, hit or play in sports with highly repetitive arm motions and or are repetitive with poor position training; stresses on the athletes arm and elbow can lead to a wide range of overuse injuries. Problems most often occur at the inside of the elbow because considerable force is concentrated over the inner elbow.
Injuries that can occur from incorrect or poorly trained, HYPO-ANGLE (less than 90 degrees) elbow positions in repetitive sports that require a trained 90 degree elbow angle for performance success:
Flexor Tendinitis: repetitive throwing or high speed racquet sports can irritate and inflame the flexor/pronator tendons where they attach to the humerus bone on the inner side of the elbow.
Ulnar Collateral Ligament (UCL) Injury: the ulnar collateral ligament (UCL) is the most commonly injured ligament in throwers and servers. Injuries of the UCL can range from minor damage and inflammation to a complete tear of the ligament.
Valgus Extension Overload (VEO): During the throwing and serving motion, the olecranon and humerus bones are twisted and forced against each other. Over time, this can lead to valgus extension overload (VEO), a condition in which the protective cartilage on the olecranon is worn away and abnormal overgrowth of bone develop.
Injury prevention and rehabilitation :
The average athlete training in basketball, baseball or tennis will use one or both of their arms hundreds of times during the week of practice and games. Repetitive arm and elbow position sports, if improperly trained will contribute to tendon and joint distress. Although causes for elbow and arm distress are varied, limiting the athletes exposure to poor arm position will assist them in performance and mitigate future arm injuries.
Athletes that are recovering from arm and elbow problems can utilize playright supersleevestm unique design to control the arm angle to 90 degrees or greater and with its unique compression fabric construction can support, control movement and retrain the athlete to correct positions.
