Midfoot Strike vs. Heel Strike in Running: A Simple Look
When it comes to running, one hot topic is whether to go for a midfoot strike (MFS) or a heel strike (rearfoot strike, RFS). This choice can affect how well you run, how likely you are to get injured, and how your body moves. Let’s break down the pros and cons of each foot strike style in a more casual way.
Heel Strike (Rearfoot Strike)
Pros:
Energy Efficiency: Heel striking works well for slower paces, using your body's natural rhythm and the cushioning in modern running shoes to your advantage.
Common Among Runners: A lot of runners, about 70-80%, tend to heel strike, especially since it fits well with traditional running shoes.
Cons:
Injury Risk: Heel striking can lead to higher impact forces, which might increase the chances of getting injuries like shin splints or knee pain.
Less Effective at Higher Speeds: When you pick up the pace, heel striking can slow you down because it creates more braking forces.
Midfoot Strike
Pros:
Lower Impact Forces: Midfoot striking can help reduce the peak forces on your body, which might help prevent injuries.
Adaptability to Speed: Runners who go faster often use a midfoot strike, making it easier to switch from landing to pushing off.
Better Force Distribution: This style spreads the impact forces more evenly across your foot and leg.
Cons:
Adaptation Period: If you decide to switch to a midfoot strike, it can take some time to get used to it, and you might feel soreness in your calves and Achilles initially.
Energy Costs: For those who are new to this style, midfoot striking might feel less efficient when running at slower speeds.
Should You Change Your Foot Strike?
Consideration of Goals: If you’re worried about injuries linked to heel striking, trying out a midfoot strike could be worth it. However, there’s no clear evidence that one is better than the other for avoiding injuries.
Adaptation Risk: Changing your foot strike suddenly can lead to new kinds of stress on your body, which might cause different injuries. It’s best to ease into it and focus on building strength.
Performance Context: Elite runners often go for midfoot or forefoot strikes because they work better at high speeds, but for casual runners, the differences in efficiency and injury risk might not be that big.
Conclusion
Both heel and midfoot strikes have their ups and downs, and which one works best can depend on how fast you run, the type of terrain, and your training background. While midfoot striking might help with reducing impact forces, making the switch should be done carefully to avoid injuries. Ultimately, sticking with your natural foot strike, along with good training and strength exercises, might be the best way to go.
