CSCS Exam Practice questions with correct answers

A 33-year-old female long-distance runner typically finishes marathons in less than 3:15. She has recently moved from Nebraska (altitude less than 1,640 feet or 500 m) to Colorado (altitude above 9,843 feet or 3,000 m). What changes are likely to occur within the first three months of her move with regard to aerobic performance? Answer A decrease in VO2max is likely at first, which will likely mean marathon times over 3:30. When she gets to Colorado she will experience hyperventilation (at rest and with exercise) and an increase in cardiac output (30-50%) to accommodate the reduced partial pressure of oxygen. After two weeks, her body will begin to form more hemoglobin, increase capillarization, and increase the diffusing capacity of oxygen through pulmonary membranes A collegiate cross-country runner increases her mileage two months before the start of preseason conditioning. Because this will be her last year of collegiate competition, her mileage increases are significantly greater than in years past. She begins to notice that her muscles are more sore than usual after workouts. Her times remain good, and after an examination by the head athletic trainer she learns that her body composition, blood pressure, and resting heart rate are essentially unchanged since testing two months earlier. Is this athlete overtrained? What is the difference between overreaching and overtraining? If this pattern of unsupervised mileage increases continues, what might begin to happen to this athlete physiologically? Will her performance improve? Answer This athlete has not become over trained, though she may be overreaching. If her overreaching continues, the overtraining syndrome is likely to occur, causing, among other things, decreased VO2max, body fat percentage, muscle glycogen, lactate, and total testosterone concentration. In addition, muscle soreness, creatine kinase, and submaximal exercise heart rate are likely to increase. The biggest factor will be that performance is likely to decrease drastically. Parents of an 8-year-old boy and an 11-year-old girl want to enroll their children in a resistance training program at the local community center. They believe that resistance training will help make their children stronger and faster (and maybe even improve their soccer performance), but they ar
