Potential energy represents the height level of the body's center of mass. Near the maximum value, it can be considered a jumping position, and near the minimum value, it can be considered a sitting position. Specifically, a value of 0.4 typically corresponds to the initial standing position. At a peak value of 1 corresponds to actions like significant jump, 0.7 to actions like small jump, 0 to actions like sitting. 

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.
