Running Doctor: Muscle pulls and tendon tears
Muscle pulls and tendon tears are a common occurrence in all sports. As you play, the muscles are rapidly contracting against resistance. The harder you play, the greater the force causing the muscle fibers to tear. In some cases, a complete rupture of the muscle-tendon apparatus is possible.
The majority of the leg muscles insert into the foot. Any muscle can tear or rupture: however, the most common muscle is the plantaris muscle which originates above the knee and inserts into the heel joining the Achilles (heel cord) tendon.
The plantaris has no real vital function as the adjacent gastrocnemius and soleus muscles team up with the Achilles tendon for support. However, if the Achilles tendon tears, there is a functional injury to the leg, which can no longer push the foot off the ground.
If this occurs, it is important to seek medical attention, If there is no rupture, then utilize rest, ice, compression and elevation. This will help reduce the pain from swelling and also the black and blue discoloration that comes from bleeding after injury. After using ice for two days, use ice massage for eight to 10 minutes followed by heat for 20 minutes a few times per day.
Minor muscle pulls should not be ignored as continues stress on these areas may cause more serious injuries. Once the injury heals, start rehabilitation with light stretching and strengthening exercises.
Prevention of leg muscle-tendon injuries as they relate to the foot, require a re-evaluation of training methods to avoid excessive stress on the injured area.
It is also necessary to do warm-up and cool down exercises. Also, any biomechanical foot imbalances and excessive pronation and inward rotation of the foot which will pull the leg muscles, should be corrected with foot inserts.
