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 maxima, we identify the ranges where the values reach a peak within the dataset. A local maximum is a point where the value is higher than its neighboring values. This indicates periods of high activity or dynamic movement. The detection is based on a threshold percentage (e.g., 80% of the maximum value) to focus on the most significant peaks. The output lists the frame ranges where these peaks occur and their respective values.
