Objectives Get familiar with different types of lifts; back, shoulder, leg, arm and torso pull. Measure maximum voluntary lifting capacity MVLC for different lifting types. Recognize the effect of gender on the lifting types. Introduction In normal life human perform different tasks, one of these tasks is material handling (lifting). Lifting types are classified according to the contracted muscle used in the lifting task, such as back, shoulder, leg, arm and torso pull. All these types are effected by factors such as age, gender, posture, health and training (fitness). Procedures We performed three types of lifting: 1. Arm lifting: while performing this type of lifting, the arm should only lift the handle without using any help from the knee or back. The elbow should be at right angel. 2. Shoulder lifting: lifting is done by using shoulder, the handle level should stay as the arm lifting level. 3. Torso lifting: the handle is placed at 17 inches of the base. The base is placed against the wall. The handle should be about the shoulder width , then we pulled and lean back, without using our legs. Each student should perform three trials from each type, between each trail and the other, there is a 2 min. break.
