Why Change of Direction Matters More Than You Think
When most people think about speed, they picture sprinting in a straight line. In reality, that’s rarely how athletes—or even active individuals—move. Sports and daily activities are filled with moments that require you to slow down, control your body, and move in a new direction.
Traditionally, many people referred to this as agility. Today, you’ll often hear it called change of direction (COD)—and it plays a critical role in both performance and injury prevention.
Change of direction is more than just being “quick.” It involves the ability to decelerate under control, position your body efficiently, and then re-accelerate in a new direction. These movements happen rapidly and often under unpredictable conditions, which makes them both physically demanding and highly skill-dependent.
Research has shown that change of direction is not just an innate ability—it is a trainable skill. How well an athlete performs these movements can influence not only how fast and efficient they are on the field or court, but also how much stress is placed on their joints during high-demand situations. When this skill is underdeveloped, athletes may rely on compensations or poor mechanics, which can increase strain on the body over time. When it is trained intentionally, it can improve movement efficiency, enhance performance, and help reduce the risk of injury.
Many non-contact injuries—especially those involving the knee—occur during moments of deceleration, cutting, or landing rather than during straight-line running. When the body is not prepared to properly absorb and control force, that stress is often transferred to joints and surrounding structures. This is one of the reasons why change of direction training is so important. It helps athletes develop the ability to manage these forces more effectively.
At Ignite Performance Physical Therapy, we take both a clinical and data-informed approach to understanding how athletes move. One way we do this is through movement assessments such as the Landing Error Scoring System (LESS), paired with tools like the VALD ForceDecks. These allow us to evaluate how an athlete:
Absorbs force
How well they control their body during landing
Whether there are meaningful differences between sides.
This type of information gives us a clearer picture of how someone is moving and where they may be at risk. It also helps guide more individualized decisions when it comes to training progressions, rehabilitation, and return-to-sport planning. Strength is important, but how that strength is expressed during movement is what ultimately matters.
Before athletes can effectively change direction at high speeds, they need to build a foundation of control. This includes developing coordination, foot placement, and body awareness. Early-stage training often focuses on simple drills that challenge these qualities in a controlled environment. While these may not look complex, they are essential for building the foundation needed for more advanced movement.
When athletes skip these foundational steps and move too quickly into high-speed cutting or reactive drills, they often lack the control needed to perform them efficiently. This can lead to poor movement patterns, unnecessary compensation, and increased injury risk. Progression matters, and developing control before adding speed or complexity is a key part of long-term success.
For athletes and active individuals alike, improving performance and reducing injury risk is not just about doing more. It is about doing the right things, at the right time, in the right way. Change of direction training is a great example of this. It requires intention, progression, and an understanding of how the body moves under load.
Over the next few weeks, we will continue to break this down further by looking at how to properly decelerate, how to improve cutting mechanics, and how to safely progress change of direction training.
