Hyperextension <\/a>occurs when you swing your arm or kick your leg and then allow it to lock out all the way. The most obvious example would be when throwing a punch. In martial arts, you are taught to throw punches and then stop with the elbow slightly bent. Allow the arm to extend fully and the impact will be in the elbow, leading to irritation and potential damage.<\/p>\n\n\n\nOther sports may also incur the same damage.\nAttempting to kick a ball and missing for instance, or playing tennis with too\nmuch vigor. In fact, the latter is one of the most common causes of tendonitis:\ntennis elbow is a form of tendonitis after all!<\/p>\n\n\n\n
Always make sure to stop the movement short,\nand not to put 100% effort into a kick, throw, or punch, unless there is\nsomething there to absorb the impact other than your joint.<\/p>\n\n\n\n\n\n\n\n
