Ankle Sprain Running Injury


Ankle Sprains are a very common type of injury for runners, especially trail runners. But even for road runners, it does happen as well when stepping on a rock, uneven terrain, holes or unexpected curbs. On the trail when running on technical trail, downhill or even on flat trail, ankle sprain happens often. It also happens often on flat and non-technical terrain once our brain relaxes, and we’re not paying attention to the ground. Our brain needs to be connected to our main muscles which we put a lot of impact on, such as our ankles, feet, calf muscles, glutes, core. Keeping our brain connected to these muscles will keep us strong and stable and prevent injuries. Also, if our brain isn’t aware of how our ankle should react, we’re most likely to trip over a rock, or branch or downhill and roll our ankle. Once we get injured or weakened our ankle due to other injuries, 80% of all ankle sprains come from previous injuries. And up to 20% of all sports injuries are ankle sprains. According to our lifestyle and training plans, if other parts of our body and muscles or our feet are weaker, this will increase the risk of ankle sprain. With the current type of lifestyle, sitting down for hours for online work, our feet and other muscles supporting our ankles are much weaker.


The ankle’s physiology is one reason why inversion injuries are so common. The inside of the ankle is much more stable than the outside, especially when the toe is pointed (plantar flexed). The most common type of ankle sprain involves the ligaments on the lateral (outside) of the ankle. This type of injury, happens most often by rolling the ankle inwards, or stepping on a rock while running, which can damage one or all three ligaments, and even fracture the ankle bone (fibula).


Single-Leg Balance Test


To prevent any type of ankle or foot injury while running, to perform a single-leg balance test is a reliable way to predict the possibility of future ankle sprains.


1. Stand barefoot on a flat surface.

2. Balance on one foot with the opposite leg bent without touching the weight-bearing leg.

3. Focus the eyes on a target, then close them for 10 seconds.

4. Perform on both sides.


If you feel any imbalance, or your foot moves on the floor, the arms move, the legs or foot touch down, the test failed and confirms your foot weakness.


How to Prevent Ankle Sprains


When we get the test result that our ankles are weak or dysfunctional, we can reduce the risk of injury or re-injury by strengthening our feet and ankles, taping, bracing and stretching the targeted joint. Another important option to prevent an ankle injury is wearing the proper shoes. Wearing high cushioning trail shoes are very comfortable, but our feet are farther from the ground, causing less stability, and increasing the risk of rolling our ankle. Wearing shoes that still have good cushioning but that are more stable and lower to the ground, will add less stress on the weaker lateral (outside) part of the ankle. And to wear the right type of shoes according to our foot type and structure will prevent feet and ankle injuries.


Foot Strengthening Exercises

Before performing these exercises, roll out the bottom of the foot with a small golf ball.


1. Toe Spread

8. Standing on a Single Leg on a Stability Disc or Bosu Ball

What it does: Strengthens the glutes, foot, core, and improves foot strength and balance.

How to do it: Stand on a Stability Disc or Bosu ball on a single leg to try to stay balanced. As you progress, try to do single leg deadlifts or single leg squats. Perform for 30-60 secs on each side.


9. Calf Stretch

What it does: Relieves foot, shin and heel pain; helps with Achilles Tendonitis and Plantar Fasciitis.

How to do it: Face a wall and keep your heels on the ground. Stretch your arms for support against a wall. Take a step backward with one leg. Bend the front knee and keep your back leg straight. Lean forward slightly, and push your back heel into the ground. Switch legs.
