EPE 335 - Biomechanics LAB: Movement Description Recommended Reading Assignment: Textbook: Chapter 2 Introduction: In order for descriptions of body segments to be meaningful, movement specialists must be able to communicate with one another using a standard set of nomenclature. In general, planes and axes of motion are used to describe the orientation of the body segments while joint action nomenclature is used to describe the actual movement at a particular joint. Using the anatomical position as a reference, the figure and table on the back of this page display the cardinal planes and axes of motion, selected directional terms, and definitions of fundamental joint actions. Purpose: To review terminology used to describe human movements, including planes and axes of motion and joint actions, and to utilize this terminology in the analysis of joint actions for selected movements. General Procedures: Using the movement analysis data sheets that follow, provide the requested information that describes each of the following movements: 1) biceps curl; 2) shoulder press (wide grip); 3) bench press (wide grip); 4) push up (narrow hand placement); and 5) sit-up with a twist. Your laboratory instructor will demonstrate these five movements for you. Assignment: You should complete this entire exercise before leaving lab. You do not need to turn anything in. Verify with the lab instructor that your solutions are correct. Use the completed worksheets to help you prepare for next week’s quiz and upcoming exams. 1) Biceps Curl Joint / Movement Start position Joint action(s) Plane Axis Elbow / raise (starting with dumbbells in a lowered position) Elbow / lower (starting with dumbbells in an elevated position) 2) Shoulder Press (wide grip) Joint / Movement Start position Joint action(s) Plane Axis Elbow / push up (starting with dumbbells in a lowered position) Shoulder / push up Elbow / return (starting with dumbbells in an elevated position) Shoulder / return3) Bench Press (wide hand placement) Joint / Movement Start position Joint action(s) Plane Axis Elbow / push up (starting with dumbbells in a lowered position) Shoulder / push up Elbow / return (starting with dumbbells in an elevated position) Shoulder / return 4) Push Up (narrow hand placement) Joint / Movement Start position Joint action(s) Plane Axis Elbow / push up (starting with torso in a lowered position) Shoulder / push up Elbow / return (starting with torso in an elevated position) Shoulder / return 5) Sit-up with a twist (upward movement only) Joint / Movement Start position Joint action(s) Plane Axis Elbows (starting with torso in a lowered position) Shoulders Torso Hips Knees
