The object in using a lever is to amplify the input force to create a greater output force; it is then said to have a high mechanical efficiency. In this situation, energy is not lost or diminished, and the task of moving or rotating an object takes less effort than it would without the lever. Used correctly, the principle of the lever is ideal for wrestlers. It benefits mechanical efficiency while helping to preserve energy and maintain a good pace while engaged in the constant, high-energy motion of a wrestling match. The most effective wrestling performance, after all, is one that accomplishes the greatest results with the least amount of effort.

The three classes of levers are defined by the position of the fulcrum in relation to the applied and resistance forces. Each class of lever is visible on the wrestling mat in certain moves, and the wrestler gains advantage in each class by moving the point of force application or increasing the amount of force applied.

Class One Levers

A class one lever is defined as a lever in which the fulcrum is in the center, and the applied force and resistance forces are on either side. The level of the resistance and applied force in a class one lever changes depending on the position of the fulcrum. When the fulcrum is closer to the resistance force, the applied force has an advantage. When the fulcrum is closer to the applied force, then the resistance force will have the advantage. Two common examples of class one levers are a crowbar and a pair of scissors.
