Shin splints happens to athletes of sports that involve a lot of sudden and shifting movements which consequently put a lot of pressure on the lower legs. If you’ve ever run a trail ultra, then you know that ultrarunners are susceptible too. In fact according to The Physician and Sports Medicine journal, this kind of injury comprises around 13 to 17 % of all running injuries.

What are shin splints?

This injury to the lower legs is commonly characterized by pain in two possible areas. It could be felt on the front and/or outer side of the shin, or it could come from the lower and inside part. More often than not the discomfort comes at the start of a training activity, eases up during the session, and then returns afterwards. Some pain may also arise when the feet and toes are bent back. There are cases where you might feel small lumps along the inside of the shinbone.

When athletes feel pain anywhere along their lower legs they usually call it ‘shin splints’. But the phrase frequently serves as an umbrella term that may actually refer to a number of specific conditions. The thing about shin splints is that it shares similar symptoms with other lower leg injuries like stress fractures for example.

Medical professionals use the term medial tibial stress syndrome (MTSS) and some specialists say that the pain comes from damage or inflammation of the sheet that covers the tibia (the larger bone in lower leg or shinbone). Athletes and runners have a penchant for self-diagnosing their aches and discomforts. If your lower legs are on the line however, it would certainly be safer to have them examined and accurately diagnosed by doctors.

What causes them?

Most of the experts agree however that shin splints or MTSS is typically the result of too much force and pressure applied to the shinbone and its connective tissues. This stress more often than not is biomechanical in nature or comes from bad training practices. Overpronation for example is said to be a contributing factor to this injury. A sloppy running form can stress out the connective tissues as well. Excessive mileage is an erroneous practice that ultrarunners often commit and shin splints are just one of the injuries that can result from this mistake.

How to prevent shin splints

There are the usual therapeutic and medication solutions to relieve lower leg pain. But you need to address the causes of this injury in order to more effectively avoid or prevent it from becoming a recurring problem. Footwear and possibly corrective supports appropriate to your foot type might be necessary. Always be conscious of your stride movements and avoid making heel strikes as much as possible. At the same time, don’t always run on hard surfaces. Try other softer but stable terrain to give your lower legs a break from the hard rebounding force that comes from pavements. Tight calves are more susceptible to stress so stretching is important to make them flexible and better at absorbing pressure. Exercises that involve flexing your feet and toes upwards and towards your shins can make the muscles attached to the tibia stronger and thus making your lower legs more resilient against shin splint injury.
