Kinetic energy represents the kinetic energy of the whole body. Near the maximum value, the movement is dynamic, indicating that the body is actively performing an action. Near the minimum value, the movement is static, suggesting that the body is preparing to act. 

To find the local minima, we identify the ranges where the values reach a low point within the dataset. A local minimum is a point where the value is lower than its neighboring values. This indicates periods of less activity or reduced movement. The detection is based on a threshold percentage (e.g., 20% above the minimum value) to focus on the most significant dips. The output lists the frame ranges where these dips occur and their respective values.
