In a second-class lever, the weight (or resistance) is between the fulcrum (or pivot point) and the effort (or force). Second-class levers increase the force applied. Second class lever – the load is in the middle between the fulcrum and the effort.This type of lever is found in the ankle area. When standing on tiptoe, the ball of the foot acts as the fulcrum, the weight of the body acts as the load and the effort comes from the contraction of the gastrocnemius muscle. This second class lever is used when taking off for a jump or pushing against the blocks in a sprint start. The most common levers in the body are third-class levers.
