Causes of tendinitis

(10)

Most common tendinitises in athletes

Mechanical causes of tendinitis

The tendon is strained too much over a long period, eventually exceeding its resistance capacity. It may be caused by:

  • Bad exercise posture
  • Inadequate gear (shoes)
  • Workouts in the rain, in the cold. The working conditions (temperature) of the tendon are then significantly modified.
  • Prolonged work at more than 80% of the maximum power (too intense and too long an effort)
  • Violent physical exertion without warmup.
  • Impacts: Shocks accidentally received by tendons (when you hit an object) or caused by physical activities.
  • Slight malformation: This birth or acquired defect may become a problem when exercising due to the stress caused by movement repetition and exercise intensity

Infectious causes of tendinitis

Infections may cause tendinitises.

The most common cause is dental infections, tooth decay. This is why you should not miss your biannual visit to the dentist.

Any infection is likely to promote, or even trigger an inflammatory reaction, in a tendon or anywhere else. This process occurs when the immune system is affected by an infectious agent. In such a case, you should reduce training and get treated.

Histamine In a related way, an allergen called histamine, well know by those who are allergic to pollen, can trigger multiple tendinitises, since the histamine is involved in the inflammation process. This allergen is also found in certain foods.

Candida Albicans Tendinitises, fungal infections, fibromyalgia, allergies, insomnia and even depression can have one common cause: Candida Albicans, a microscopic fungus that takes shelter in your body without your knowledge and can become a pathogen, i.e. cause symptoms and diseases, particularly if you are in an overtraining period. Only your doctor can provide advice and appropriate treatment

A wide variety of causes

Sport physicians more commonly use the terms tendinopathy or sports-related tendinitis, because these pains usually appear progressively for various reasons:

Technical defects and inadequate sporting gesture

  • Excessive exercise
  • Poor practice
  • Lack of stretching
  • Poor physical fitness
  • Use of inadequate equipment
  • Tooth infection
  • Use of certain medications
  • Bad posture
  • Nutritional errors, including insufficient hydration.
  • Inappropriate initial treatment and lack of rest

Did you know? Using certain medications may cause a tendinitis!

There is a major risk of tendinitis or ruptured tendon when using certain antibiotics:

Fluoroquinolones, used for the treatment of urinary tract infections, but also other types of infections such as ENT or osteoarticular infections. They may be responsible for problems related or non related to sporting activities. [Example: tennis-leg] readhttp://www.irbms.com/tendinites

Advice

Achilles tendinitis is an inflammation of the tendon including all pains in the Achilles tendon. It commonly affects all athletes, but most particularly runners and joggers, usually resulting from a too high training volume and aggravated by micro-traumas due to shoe-ground interface.
