NSCA- CPT Exam Questions With 100% Correct Answers What is the name of the connective tissue that surrounds skeletal muscle - answerEpimysium How many neuromuscular junctions does each muscle fiber have - answer1 Which branch of the nervous system is responsible for activating skeletal muscles - answerSomatic Which division of the skeleton contains the skull and vertebral column - answerAxial Skeleton Which connective tissue connects muscle to bone - answerTendon What is the approximate pH of human blood at rest - answer7.4 The heart is composed of how many chambers - answer4 What two things occur to facilitate a redistribution of blood flow at the onset of physical exercise - answerSkeletal muscle arteriole dilation and nonactive organ arteriole constriction What refers to the amount of air moving into and out of the lungs at rest during normal breathing - answerTidal volume What is correct regarding maximal oxygen uptake (VO2max) - answerIt relates to the heart's maximal ability to eject blood (maximal cardiac output), it represents the maximal ability of skeletal muscle to extract oxygen, and it represents the ability to use maximal AVO2 difference to aerobically produce energy What are characteristics of bioenergetics - answerBreakdown of food, conversion of chemical energy to mechanical energy, and breakdown of chemical bonds How many molecules of ATP are produced from glycolysis of one molecule of glucose in blood? - answer2 What energy system is the primary source of energy at rest and during aerobic activities - answerOxidative Glycogen becomes the preferred fuel source at intensities above about what percent of maximal oxygen uptake - answer60-75% When relying on the slower ATP-producing energy systems, ATP can be produced as long as the body has a good supply of what - answerMuscle glycogen, fatty acids, and protein In biomechanics, the term body may refer to what - answerthe human body, limb segment, and piece of chalk What is the equation that represents Work (W) - answerForce x Distance moved (displacement) What is correct regarding rate of force development - answerIt is the ratio of the change in force over the change in time, it is time rate of change of force, and it can be improved with resistance training What is correct regarding the use of heavy metal chains on barbells - answerthey can be used with linear movements, the chains add resistance throughout the range of motion, and the chains can be used in exercises such as the squat or bench press With water resistance, if the surface area is larger, then the exercise will be _____ - answerharder What is correct regarding stress responses to resistance exercise? - answerit can lead to increase in bone mineral density, it leads to muscle growth, and it results in increased strength Steroid hormones - answerTestosterone, estrogen, and any hormone derived from cholesterol What is correct regarding endocrine adaptations to resistance exercise - answerTestosterone has been shown to increase, resistance exercise leads to up regulation of androgen receptor content, and growth hormone does not appear to increase What is correct regarding individuals who possess the ACTN XX genotype - answercommercial DNA testing companies can inform individuals if they possess it, the ACTN gene is responsible for producing a structural Z-line protein found mainly in type II muscle fibers, and being a carrier of the ACTN XX genotype does not present deleterious health consequences Approximately how often does resistance exercise need to be performed to prevent detraining - answer1 or 2 session per week What increases during an aerobic exercise bout - answerRespiratory exchange rate What is the Fick Equation - answerVO2 (L/min) = Cardiac output (Q) x A-VO2 difference What is correct regarding the skeletal muscle adaptations to chronic aerobic exercise training - answerIncreased muscle myoglobin stores, no change in type II muscle fiber cross-sectional area, and little to no change in type I muscle fiber cross-sectional area
