What is a significant feature of the class 3 lever system in human movement?

The class 3 lever system is characterized by having the effort applied between the load and the fulcrum. This unique configuration is particularly significant in human movement because it is designed to enhance speed and distance rather than purely lifting heavy weights. When the effort is applied closer to the fulcrum, as seen in the human arm during activities like throwing or swinging, it allows for a greater range of motion and faster movements of the load, which is typically the hand or tool being moved. This capability to generate speed and maximize distance traveled by the load is crucial in various athletic endeavors, making it an essential feature of this type of lever system in the context of human movement.
