Many kayakers experience shoulder injuries at some point in their paddling hobby. Most of the time, this injury can be prevented. The best prevention is strong adherence to the Paddler's Box. The Paddler's Box uses the arms like struts and ALWAYS keeps the center of the paddle shaft visually in front of their face. If you can't readily see the middle of your kayak paddle shaft, you are risking injury. Another good rule of thumb is to never let the center of the paddle shaft rise above your eye balls. Paddlers that violate this rule often separate their shoulders when a paddle blade gets caught on something like a rock. A loose paddle grip also helps to avoid injuries. When executing a draw or sculling stroke, watch where you are going. This requires you to turn the upper part of your body to your side (twisting your torso). When you perform a kayak roll, your head follows your lead paddle blade. Here is a great video demonstrating weight bearing exercises you can use to strengthen your shoulder muscles: Gym Exercises for Shoulder Strengthening. Here is the Davey Hearn shoulder Rehab article: Davey Hearn Shoulder Rehab. Watch the following video on a kayaker running National Falls on the Upper Yough and dislocating his shoulder. Watch closely and you will notice that his paddle shaft is way above his head - a big no-no: Kayaker dislocating their shoulder. We wrap this up with a very extensive article on shoulder dislocation.
