Agility consists of two main components: speed in changing direction and cognitive factors (101) If programming to enhance buffering capacity, when should the strength and conditioning professional coordinate the inclusion of 3 on 3 small sided games for a collegiate soccer? a. pre-season b. in-season c. off-season - correct answersb. in-season A high school football team is in the hypertrophy phase of the training cycle. The risk of overuse injuries in the upcoming season is increased when the emphasis of the daily training sessions is which of the following? a. work hard, train heavy on each set b. individualized progression c. incorporation of multijoint exercises - correct answersa. work hard, train heavy on each set An athlete has set up their phone to play selected music as a means of motivation during the training session. What is the maximal recommended sound level for health and safety? a. 90 dB b. 100 dB c. 110 dB - correct answersa. 90 dB Two considerations for installing a sound system are speaker volume and placement. The sound should be less than 90 decibels so that athletes can hear instructions and cues (2). Speakers should also be elevated and in a corner to prevent any damage and to project sound toward the middle of the room so that it is more evenly distributed. What is the recommended ceiling height for training facilities where athletes will be performing Olympic lifts and plyometric drills? a. 9-11 ft (2.4-3.4 m) b. 15-17 ft (4.6-5.2 m) c. 12-14 ft (3.7-4.3 m) - correct answersc. 12-14 ft (3.7-4.3 m) The scope of practice of a certified strength and conditioning coach includes which of the following? a. conduct sport-specific testing sessions to assess sport skills b. apply scientific knowledge to train athletes to improve athletic performance c. apply scientific knowledge to train individuals to improve strength & conditioning - correct answersb. apply scientific knowledge to train athletes to improve athletic performance Certified Strength and Conditioning Specialists are professionals who practically apply foundational knowledge to assess, motivate, educate, and train athletes for the primary goal of improving sports performance. They conduct sport-specific testing sessions, design and implement safe and effective strength training and conditioning programs, and provide guidance for athletes in nutrition and injury prevention. Recognizing their area of expertise is separate and distinct from the medical, dietetic, athletic training, and sport coaching fields, Certified Strength and Conditioning Specialists consult with and refer athletes to these professionals when appropriate. What assessment allows for the most effective development of an aerobic endurance training program? a. VO2max b. lactate threshold c. 300-yard shuttle - correct answersb. lactate threshold When assessing a new change of direction test with a team of volleyball players, the scores are found to have a high correlation with the T-test. This represents what type of validity? a. discriminant validity b. face validity c. concurrent validity - correct answersc. concurrent validity Construct validity is the ability of a test to represent the underlying construct Face validity is the appearance to the athlete and other casual observers that the test measures what it is purported to measure Content validity is the assessment by experts that the testing covers all relevant subtopics or component abilities in appropriate proportions Criterion-referenced validity is the extent to which test scores are associated with some other measure of the same ability. There are three types of criterion-referenced validity: concurrent, predictive, and discriminant. Concurrent validity is the extent to which test scores are associated with those of other accepted tests that measure the same ability. Convergent validity is evidenced by high positive correlation between results of the test being assessed and those of the recognized measure of the construct Discriminant validity is the ability of a test to distin-guish between two different constructs and is evidenced by a low correlation between the results of the test and those of tests of a different construct Predictive validity is the extent to which the test score corresponds with future behavior or performance. A female athlete runs a 40 m (43.75 yards) sprint test in 6.1 sec. The team average is 5.93 sec +/- .2 SD. The athlete is expected to run 0.04 seconds faster following participation in a training program based on what principle? a. smallest worthwhile change b. calculated individual effect size c. comparison to normative data - correct answersa. smallest worthwhile change Smallest worthwhile change refers to the ability of a test to detect the smallest practically important change in performance. The ability to track changes with a fitness test depends on the validity and reliability of that test. The smallest worthwhile change can be determined in a number of ways, but it is typically calculated as 0.2 of the between-subjects standard deviation (51). For example, if the standard deviation for a vertical jump test is 10 cm in a group of female athletes, this would mean that the smallest worthwhile change for this group of athletes is 2 cm (0.2 10 cm). What is meant when the term 'rate-limiting step' is used to describe a metabolic reaction? a. the reaction can easily be bypassed with alternative reactions b. the reaction's enzymatic activity can be regulated by the cell c. the reaction has reached equilibrium - correct answersb. the reaction's enzymatic activity can be regulated by the cell The rate-limiting step, also known as the rate-determining step, is the slowest step in a multi-step reaction that determines the overall rate of the reaction An increase in the cross-sectional area of the muscle fiber following resistance training is associated with which of the following? a. decreased sarcoplasmic reticulum density b. decreased mitochondrial density c. decreased cytoplasmic density - correct answersb. decreased mitochondrial density Resistance training has been shown to increase myo-fibrillar volume (128), cytoplasmic density (132), sarcoplasmic reticulum and T-tubule density (9), and sodium-potassium ATPase activity (71). Collec-tively, these changes act to facilitate hypertrophy and enable greater expression of muscular strength. Sprint training has been shown to enhance calcium release (150), which assists in increasing speed and power production by promoting actin and myosin crossbridge formation. Heavy resistance training has also been shown to reduce mitochondrial density (133). While the number of mitochondria actually remains constant or can slightly increase throughout a training phase, mito-chondrial density is expressed relative to muscle area. Increases in muscle CSA occur disproportionately to mitochondrial proliferation, and consequently the den-sity of mitochondria per unit volume is act
