Achilles Tendon Injury Prevention

The Achilles tendon, sometimes more formally called the calcaneal tendon, attaches the muscles of the calf (soleus, gastrocnemius, and plantaris) to the heel bone (calcaneus).

It is one of the longest tendons in the body and it helps us push off the ground with the front of the foot as in walking or running. (Tendons attach muscles to bone and ligaments attach bones to bones.)

"The Achilles," as it is known colloquially in sporting circles, is susceptible to serious injury when it tears. This is called an Achilles rupture. It may be a partial or complete rupture. Often a pop or cracking noise can be heard at the instant of the tear.

While athletes in heavy training and competition are susceptible to Achilles tendon tears, many injuries occur in middle-aged athletes attempting to exercise without progressively building up their physical fitness.

Achilles Tendonitis

The Achilles tendon is extremely important to motion. Since it gets a lot of use in most physical activities, it is also more susceptible to serious injury. Achilles tendonitis, one of the more common potential Achilles injury issues, is a typically painful condition that occurs when the Achilles tendon is damaged from overuse or chronic degeneration.

As an overuse injury, Achilles tendonitis occurs from repetitive use of the tendon that results in small tears of the tissue over time. Over a period of time, swelling and pain can result in the tendon. Some common activities and conditions that can potentially result in Achilles tendonitis include:

  • Running
  • Jumping
  • Having tight calf muscles, which is why stretching is highly recommended.
  • Having excessively flat feet

The symptoms of Achilles tendonitis typically progress gradually over time.

Prevention of Achilles Tendonitis

It may not always be possible to prevent developing Achilles tendonitis, or other Achilles injuries, there are steps that can be taken to reduce risk. Some preventative measures include:

  • Stretching of the calf muscles
  • Eccentric strengthening of the tendon
  • Increasing activity level gradually, rather than quickly
  • Getting adequate rest during strenuous activities
  • Strengthening overall leg muscles, especially the calves. Axial loading exercises, like farmer's carries on your toes, is a good choice.
  • Slow resistance training may improve symptoms in the short term, but eccentric strengthening is more effective in the long term.

Achilles in Ancient History

Achilles is the main heroic subject of Homer's "Iliad." He is widely considered to be the greatest and fastest hero of the Greeks during the Trojan War. Achilles is credited with slaying the Trojan hero Hector directly outside of the gates of Troy.

To prevent Achilles’ early death, and also in an effort to make her son immortal, Achilles' mother, Thetis, took him to the River Styx, which was thought to hold powers of invulnerability. Thetis held her son by the ankle and dipped him into the River Styx. This made Achilles invulnerable everywhere, except for the one area that was directly where his mother’s fingers had gripped him while dipping him into the river.

The water did not touch his body in the Achilles tendon area. Since his spot of vulnerability was his heel, the term Achilles' heel has come to refer to someone’s weak spot. There are several synonyms for an Achilles’ heel in modern language including a weak point, a weak link, a flaw, an imperfection, a defect, a weak spot, or a chink in the armor.
