NCSF FINAL EXAM STUDY GUIDE What term represents the transfer of energy across joints to support voluntary movement? - ANS - Kinetic chain The posterior pelvic tilt seen in this picture, is commonly seen in bilateral leg exercises a result of tight ____________________. - ANS - glutes Ankle dorsi flexion is caused by _________________. - ANS - a concentric contraction of the anterior tibialis When performing biceps and triceps exercises, what joint action should occur at the shoulder? - ANS - no joint movement What exercise is used to cause elevation of the shoulder complex (scapulae and humerus)? - ANS - barbell shrug What is the natural curvature of the thoracic spine? - ANS - kyphotic curve When performed correctly, what is the prime mover responsible for hip extension during the back squat? - ANS - gluteus maximus What back muscle is the prime mover for the seated row exercise as it is responsible for retraction of the scapula? - ANS - rhomboids Which of the following exercises requires the greatest contribution from trunk stabilizers when using 80% 1RM? - ANS - barbell bent-over row The performance of dumbbell side raises occurs in what movement plane? - ANS - frontal What position of the knee is necessary to fully stretch the gastrocnemius when the ankle is in full dorsi flexion? - ANS - fully extended What muscles are used to globally stabilize the humerus during the bench press? - ANS - latissimus dorsi and deltoid Based on the principles of stability what exercise would be the most difficult to stabilize? - ANS - standing single-arm dumbbell press To correct the movement error seen in the image, the client should be instructed to ____________. - ANS - take a broader step and push the back leg downward Which of the following refers to the cumulative input to the nervous system that relays body and positional movement? - ANS - proprioception What muscle is the prime mover for the lateral lunge performed in the picture? - ANS - hip abductors Clients should be instructed to retract the scapula during the seated row exercise in order to effectively train the: - ANS - rhomboids Aerobic metabolism in the muscle cell occurs within which organelle? - ANS - mitochondria What anabolic hormone is released in higher concentrations in response to heavy resistance training? - ANS - testosterone Which pair of movements employ reciprocal inhibition in a training set aimed at improving strength and flexibility? - ANS - seated leg extension and hamstring stretch Which of the following is the only energy substrate that can be metabolized aerobically or anaerobically to produce ATP? - ANS - glycogen What type of contraction is performed by the abdominals and erector spinae muscle group during the performance of a push-up? - ANS - isometric What physiological response occurs when lactate builds up in the blood? - ANS - respiration rates increase What has the greatest impact on relative hormonal response during exercise? - ANS - intensity of exercise What causes the protein-sparing mechanism to shut off during exercise? - ANS - inadequate carbohydrates Besides differences in muscle mass and strength capabilities, why do females have lower cardiac outputs compared to males? - ANS - smaller relative heart size To optimize aerobic capacity the body increases oxygen delivery and extraction by adding: - ANS - capillaries Why is it recommended to perform static stretches following exercise, and not before? - ANS - pre-exercise static stretching can reduce power output Which system of the body has the greatest adaptation rate when exposed to a new training stimulus? - ANS - nervous system Delayed-onset muscle soreness generally appears: - ANS - 24-48 hours after a training session ends Stroke volume levels off at about 40% VO2max, forcing the body to rely strictly on increased ________________ to manage cardiac output as the intensity rises. - ANS - heart rate Which of the following is a postural muscle characterized by a relatively greater slow-twitch fiber density? - ANS - soleus Which of the following recommendations woul
