Introduction: The study that involves the structure, function, and motion of mechanical aspects of the biological system is known as biomechanics. Biomechanics can deal at any level varying from a cell to the whole organ or organism.
Answer to Problem 1RQ
Correct answer: Option a “Cuff positioned at the wrist”.
Explanation of Solution
Reasons for the correct answer:
Option a. is given as “Cuff positioned at the wrist”.
Putting the weight cuff at wrist requires more effort at the shoulder joint in order to move the weight cuff through the shoulder range of motion. This is because there occurs a longer resistance arm when the weight is placed around the wrist than when the weight is placed around the elbow.
Hence, option a. is correct.
Reasons for incorrect answers:
Option b. is given as “Cuff positioned at the elbow”.
When a weight cuff is positioned on the elbow, it results in comparatively shorter resistance arm than positioning the cuff at the wrist in order to move the weight cuff through the shoulder range of motion.
Hence, option b. is incorrect.
Positioning the cuff at the wrist requires more effort to move the weight cuff at the shoulder joint through shoulder range of motion.
