What is it about?
Our study reveals fascinating insights into how our body's posture affects how we move, especially when we encounter uneven surface while running. We found that when the ground isn't even, our leg joints have to work harder, with the ankle joint playing a crucial role in absorbing or generating energy. Interestingly, how we lean our body forward or backward also changes how our legs work during these moments. Understanding these mechanics could help us improve our movements and possibly prevent injuries while navigating uneven surfaces.

Why is it important?
Our research is all about figuring out how leaning forward or backward affects how we move when we come across obstacles, like a hole in the ground, while running. Even though we know leaning upper body can change how we run, we're still not sure how it impacts the energy we use. So, we looked into how leaning affects the power in different leg joints—like the hips, knees, and ankles—when we run into obstacles. This helps us understand how our body deals with challenges, like holes, when we're out for a run.
Perspectives
Our study looked at how our legs work like springs when we run, storing and releasing energy as we move. We found that when we run into a hole or similar obstacle, our leg muscles have to work harder to manage the extra challenge, especially at the ankle. Surprisingly, we also discovered that how we hold our upper body affects where this energy goes in our legs. Understanding these things helps us figure out how to stay steady and balanced when we're running and encounter obstacles.
