Injury can occur is the biceps is asked to work too hard too quickly – such as catching a heavy weight; with the long head being the most vulnerable part; alternatively, they can rupture after a long-standing degenerative process. A rupture of this tendon is rare in young athletes but more common in older ones. It is also possible to damage the tendon close to the elbow; or the belly of the muscle itself, though these are much less common.
