Normal Achilles tendons can support a significant amount of force, but when this is put under sudden loading, especially after a gap from activities, injury to the tendons can happen. Some people have pre-existing tendonitis from repetitive spraining and healing of the tendon due to overuse, which makes them susceptible to further tearing. Occasionally, steroid injections around the tendon could lead to rupture.
For example, if an individual suddenly returns to football or racquet sports after a long period of absence, the frequent pivots and changes of direction, and sudden acceleration and deceleration, will put the Achilles tendon under a huge amount of strain which can result in a tear.
