| Week 4 Scholarly Questions and Analytical Thinking Please read/review and STUDY the meaningful Biomechanical slides and make sure you understand all of the concepts. Click HERE to READ/STUDY/LEARN. What is biomechanics? What is a motor unit? Understand how the sarcomere is affected during concentric and eccentric contraction. Understand the Muscle Length-Tension Relationship How does sarcomere length relate to tension (force production)? Understand and be able to describe and draw the Force-Velocity Relationship. What is mass? What is weight? Understand the different components of a lever including the axis of rotation, muscular effort and resistance. Understand the mechanical aspects of a lever (rotary, stabilizing, and total muscular force) What are the basic components of force? How do you calculate torque? Understand the principles discussed regarding force production of a muscle to hold a weight in the hand. What is mechanical advantage? How do you determine mechanical advantage of a lever? Draw the 3 lever classes Provide anatomical examples of each lever class |
