The beauty of cycling, is that it is a very low impact form of exercise that results in fewer injuries than higher impact activities such as running. However, the number of repetitions that cyclists perform (roughly 6000 revolutions per hour) is much greater than any other sport. Chronic injuries can occur from riding too long, too fast or too often. I always advise my patients to have a professional evaluate how their bike fits their body. An improper fit of the handlebars, saddle, frame or pedals can cause a predisposition to musculoskeletal problems aka pain and injuries. Here is a video of a professional setting up a riders bicycle.
