Torque represents the torque value on the limbs (both arms, both legs). Near the maximum value, the torque value on the body is higher (more movement) indicating that the body is actively performing an action. Near the minimum value, the torque value on the body is lower (less movement). 

To calculate the frame length, count the total number of frames in the dataset. Each frame represents a data point collected over time. The total frame length gives the duration of the motion or activity being analyzed. In this dataset, the total frame length is determined by the number of entries in the data array.
