Dear IMPACT,

Being an avid cyclist I ponder the question, can too much cycling be bad for the hip joint, and, secondly, is the size of the bike or seat height a factor? Yours sincerely,

Dear Allan,

Cycling has gained notoriety as an excellent exercise associated with causing nominal impact forces on the lower limbs and hips. In cases where there is a certain level of pre-existing ‘wear and tear' of a hip joint, the cycling action may induce a certain level of discomfort in and around the hip region, most commonly, stiffness. Generally, for most healthy individuals who don't have any overt pre-existing hip problems, a certain level of stiffness is all that one can expect from increasing time spent on the saddle. This stiffness is usually temporary and plays little consequence in risking true harm. The structures surrounding the hip joint, such as the gluteal muscles, hip flexor muscles, and iliotibial band are much more likely to be stressed than the hip joint itself. These soft tissues are not immune to developing painful repetitive overuse syndromes and may become a source of inflammation and pain. It is always wise to be properly fitted to your bicycle, particularly given that saddle position can have a dramatic effect on the working engagements of these soft tissues. Generally, the position that gives rise to the most efficient pedal stroke is also the position that is most protective from overuse injury.
