Description

B Biomechanists typically work in which of the following settings? I. rehabilitation centers in which gait analyses are often used II. universities, where they teach and perform research III. occupational consulting organizations that provide assistance to companies in analyzing tasks to determine how they could be reconfigured to reduce fatigue and injuries IV. a fitness facility that targets women A) I, II, and IV B) I, II, and III C) II, III, and IV D) I, III, and IV C A golf ball stays on the tee until the golf club hits it. Which of the following principles best describes why this occurs? A) law of projectile motion B) An object will gain more momentum if more force is applied to it across a period of time. C) Newton's law of inertia D) Newton's law of action-reaction D A person applies force to a screwdriver, causing the screwdriver to turn. The person has generated A) a fluid force B) a ground reaction force C) a hydraulic force D) torque D 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 A) occupational engineers B) work specialists C) occupational therapists D) ergonomists or human factors engineers A What is known about injury mechanisms due to forces? I. Factors related to the performer (e.g., anatomy) may predispose certain individuals to injuries. II. The number of repetitions that a person can perform per week without injury should not exceed 2000. III. The amount of force that can cause an injury is dependent on the rate at which the force is applied to a tissue.

A) I and III B) I and II C) II and III D) I, II, and III C Which is the most common force acting on a human performer? A) kinetic output B) surface area C) fluid resistance D) weight of performer A Biomechanist A describes a specific performance, while biomechanist B wants to look at the relationship between performance and specific forces. Which of these two is most likely to use inferential statistics in his work? A) biomechanist B B) biomechanist A C) Both are equally likely to use inferential procedures. D) The answer cannot be determined from the information given. TRUE Biomechanics can assist with design of equipment, artificial limbs, and orthoses for safety. A) True B) False A What is the study of the function of human beings using the principles and methods of physics and engineering? A) biomechanics B) motor behavior C) ergonomics D) kinesiology TRUE 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. A) True B) False D When an athlete is running across a field, _________ allows for the person to be propelled forward (the runner pushes down on the ground and the ground pushes the person in the opposite direction).

A) inertia B) lift forces C) acceleration D) ground reaction forces C 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? A) Consider influencing factors. B) State performance goals. C) Determine relevant biomechanical principles and movement techniques. D) Observe, measure, assess, and evaluate. C What was the discipline of biomechanics called in the past? A) motor learning B) motor development C) kinesiology D) motor control C A football player is running his 40-yard dash for scouts. What type of analysis is the scout using? A) qualitative analysis B) ergonomics C) quantitative analysis D) pressure analysis D Which of the following is a type of mechanical loading that occurs inside the body? A) gravity B) compression C) tension D) both b and c...
