Achilles Tendon Injury
A stretch, tear, or irritation to the tendon connecting the calf muscle to the back of the heel, Achilles tendon injuries can be so sudden and agonizing that they have been known to bring down charging professional football players in shocking fashion.
The most common cause of Achilles tendon tears is a problem called tendinitis, a degenerative condition caused by aging or overuse. When a tendon is weakened, trauma can cause it to rupture.
Achilles Tendon Injury Prevention
Achilles tendon injuries are common in middle-aged "weekend warriors" who may not exercise regularly or take time to stretch properly before an activity. Among professional athletes, most Achilles injuries seem to occur in quick-acceleration, jumping sports like football and basketball, and almost always end the season's competition for the athlete.
