Kinesiology Chapter 10 Test Questions with Correct A Which of the following is least likely to be a concept studied in biomechanics? - Answer- body mass index (BMI) A golf ball stays on the tee until the golf club hits it. Which of the following principles best describes why this occurs? - Answer-Newton's law of inertia Injuries to tissues of the body can be caused by forces whose magnitudes are within the limits that the tissue can tolerate if they are applied repeatedly over a long period of time. - Answer-True Biomechanics can assist with design of equipment, artificial limbs, and orthoses for safety. - Answer-True Professional scouts are timing a football player running a 40-yard dash to determine how his speed compares to other players they may want on their team. What type of analysis are the scouts using? - Answer-quantitative analysis Thomas Cureton was believed by some to have coined the term biomechanics (although others believe that Europeans may have used the word first). - Answer-False The guiding principles and concepts of biomechanics come from which of the following subdisciplines? - Answer-mechanical physics, mechanical and biological engineering, and biology Specialists who apply their knowledge of physiology, biomechanics, anatomy, and psychology in order to improve the movements, working environments, and training programs in the workplace are called - Answer-ergonomists or human factors engineers What was the discipline of biomechanics called in the past? - Answer-kinesiology Biomechanists typically work in all of the following settings EXCEPT - Answer-a nutrition facility that targets women You are analyzing the performance technique of a swimmer to see what improvements can be made to help the performer swim faster using the movement analysis model. During one of the movement analysis steps, you remember that to move faster through the water, one must reduce the force of water resistance by making the body surfaces smooth. You then decide that, for the glide phase, you will have the performer keep her arms straight and close to her body to streamline her shape. Which analysis step did you carry out? - Answer-Observe, measure, assess, and evaluate. What is the study of the function of human beings using the principles and methods of physics and engineering? - Answer-biomechanics Which of the following are the most common forces acting on a human performer? - Answer-friction, gravity, ground reaction forces, air or water resistance What is the third step in a model of analysis for biomechanics? - Answer-Consider influencing factors. When an athlete is running across a field, allow(s) for the person to be propelled forward (the runner pushes down on the ground, and the ground pushes the person in the opposite direction). - Answer-ground reaction forces An important skill for a physical activity specialist, , or allied health rehabilitative specialist is to be able to choose the relevant mechanical principles that apply to the movement of interest or to a phenomenon occurring inside the body. - Answer-biomechanist What is known about injury mechanisms due to forces? - Answer-The amount of force that can cause an injury is dependent on the rate at which the force is applied to a tissue. Industries in the 1950s needed to know the measurements of people to design seats, cockpits, and instrument panels that fit these users. What is the study of people's physical dimensions that provided this type of information? - Answer-anthropometrics Which of the following is NOT a goal of biomechanics? - Answer-to understand the relationship between mechanical laws and movement techniques of specific movements to improve the outcome or effectiveness of movements Studying how diseased blood cells respond to forces is an example of which branch of biomechanics? - Answer-nanobiomechanics A performer can move out of a stationary position when there are no outside forces acting on her. - Answer-False
