Question

QUESTION 16 When static stretching, you stretch to a point of tension, then hold the stretch for 30 seconds. Over that time, you feel the tension gradually decrease. This is an example of the relaxation response. QUESTION 17 Stress fractures in bones are caused by single loads that exceed a bone's ultimate strength. QUESTION 18 The femur would be expected to have the greatest ultimate strength when it is loaded in compression. QUESTION 19 Which of the following activities would you expect to cause the most significant increase in bone density? - swimming - plyometrics - walking - cycling QUESTION 20 Many older adults experience bone remodeling changes in which osteoclast activity increases while osteoblast activity remains unchanged. What effect will this have on bone density? - cause bone density to decrease - cause bone density to increase - cause bone density to remain unchanged QUESTION 21 Bones like the ribs that have a large proportion of spongy bone are likely to be stiffer than bones with more compact bone. QUESTION 22 You are given a tissue sample that you know is either a tendon or a ligament, but you are not sure which. You analyze the content of its matrix and find that it contains around 10% proteoglycans. From this, you conclude that the tissue is a tendon. QUESTION 23 You hear the end of a news report on a baseball pitcher who suffered a season-ending elbow injury, an avulsion of the medial epicondyle. Based on this information, the pitcher is most likely a Little League pitcher. QUESTION 24 An athlete fractures her tibia in practice, and the leg and foot are placed in a cast for six weeks, after which she starts rehab. How much strength (relative to their original strength) do you expect the ligaments of the ankle to lose over those six weeks? - < 10% - 10 - 20% - 20 - 30% - 30 - 40% - 40 - 50%
