If you've ever dealt with nagging injuries or felt like your running isn't as efficient as it could be, you might want to take a closer look at your form. Research shows that small adjustments to stride length and mechanics can make a big difference in impact forces, energy efficiency, and injury prevention.
The Science Behind Stride Length and Impact Forces
One of the most well-documented adjustments runners can make is shortening their stride. A study published in Medicine & Science in Sports & Exercise found that reducing stride length by increasing stride rate can significantly lower the mechanical energy absorbed by the knee joint. Specifically, a 10% increase in cadence reduced knee joint impact by 34%. Less impact means less wear and tear on your joints, which is crucial for long-term running longevity.
Another study in the Journal of Science in Sport and Exercise found that shorter strides combined with appropriate footwear can reduce joint stress. Many injuries stem from excessive impact forces, particularly in the knees and hips. By adjusting stride length, runners can reduce these forces and improve overall efficiency.
Does It Make Running Harder?
Some runners worry that changing their natural stride will make running feel harder or increase energy expenditure. While it’s true that altering form can take an adjustment period, research suggests that any extra effort is outweighed by the benefits of reduced impact and better efficiency. A breakdown from Sweat Science highlights that shortening your stride mimics the benefits of barefoot running, which often leads to improved biomechanics without the risks associated with landing on an overextended leg.
Making the Change: Practical Steps
If you're interested in tweaking your form, start with small adjustments:
-
Increase your cadence slightly by 5–10% while keeping your pace the same. Many GPS watches track cadence, making it easy to monitor.
-
Think about soft landings. Avoid reaching too far with your foot. Instead, let it land closer to your center of mass.
-
Strengthen your lower body. Many inefficient movement patterns stem from weaknesses in the glutes, hamstrings, and core.
Work With a Coach
Changing your running form is a process, and what works for one runner may not work for another. That’s where working with a coach can help. As a certified running and strength coach, I specialize in helping runners optimize their form, improve efficiency, and stay injury-free. If you’re ready to take your training to the next level, let’s work together to fine-tune your mechanics and build a strong, resilient body that supports your goals.
