What Are the Common Causes of Shin Splints
The underlying pathology which leads to someone developing shin splints is not conclusive. However, there are a few factors that increase the chances of someone developing the condition:
Overuse or Overtraining
A sudden or quick increase in intensity, duration or type of activity can put the muscles and joints under a lot more stress and cause shin splints. It’s best, therefore, to increase activity gradually so that the muscles have time to develop in order to support the body.
Poor Foot Biomechanics
Biomechanics means ‘movement mechanics’. When thinking about the feet, this includes the structure, function and motion. Podiatrists look at how the muscles, bones, tendons, and ligaments work together to create movement – and everyone’s feet are different. In some patients, their foot biomechanics contribute to the onset of shin splints and in these cases stretches, strengthening, foot supports and footwear can all play a part in resolving and avoiding a reocurrence of the condition.
Inadequate Footwear
Footwear that doesn’t properly support the individual biomechanics of the feet and the specific activity being undertaken can cause someone to develop shin splints. A footwear assessment and video gait analysis are two of the interventions offered at our Clinics to help patients understand what footwear is best for them so that they can get back to the sports and activities they enjoy.
Sudden Increase in Activity
Sports people in pre-season training – basketball, netball, football and so on – who are deconditioned, have weaker muscles which struggle to cope with the sudden increase in pressure and activity when activity starts up again.
Running on Hard Surfaces
The force of running or jumping jars the feet, ankles and lower limbs and creates stress through those areas. When there is an inability of the bone to deal with the load and stress, shin splints can develop.
Tight or Weak Muscles
Tightness in the soleus muscle that runs through this area of the leg can irritate the bone and the protective sheath around the bone and they become inflamed.
Inadequate Warm-Up or Stretching
Warming up and stretching the muscles of the feet, legs and hips before and after activity will help prepare the muscles before and relax them afterwards. Likewise, cross training to include exercises to strengthen the legs, ankles, feet, hips and core can provide additional support to help the body deal with new or increased activities.
Shoes that don’t support the feet
Appropriate footwear for both the sport being undertaken and the individual biomechanics of the feet (for example a low or high arch) will help support the feet during activity. The training shoes themselves should be replaced regularly. For example, runners need to change their shoes every 500 – 800 kms.
