Rectus abdominis Eccentric contractions of the _________ muscle groups decelerate a ballistic movement such as those used in running or throwing. a. agonist b. antagonist c. synergist d. stabilizing - CORRECT ANSWER b. antagonist Hyperextension of the shoulder is restricted by the range of motion (ROM) of the __________. a. posterior deltoid b. anterior deltoid c. subscapularis d. teres minor - CORRECT ANSWER b. anterior deltoid Seated knee extension on a machine has reduced ________ recruitment versus knee extension that occurs while standing (closed chain) due to the position of the hip. a. vastus medialis b. rectus femoris c. vastus intermedius d. vastus lateralis - CORRECT ANSWER b. rectus femoris Due to fiber dynamics, activities requiring a combination of elevated force and prolonged duration preferentially recruit the ________ fibers to perform the work. a. Type I b. Type IIa c. Type IIb d. Type III - CORRECT ANSWER b. Type IIa For increased stability during the exercise, the hip adductors would experience the highest force production requirements from isometric contractions during a ________. a. standing shoulder press using a single dumbbell b. seated shoulder press with barbell c. standing bilateral cable shoulder press d. the adductors are not used for stabilization - CORRECT ANSWER a. standing shoulder press using a single dumbbell The muscle indicated by the arrow is the ________ and makes up one-third of the hamstring muscle group. a. biceps femoris b. sartorius c. semimembranosus d. semitendinosus - CORRECT ANSWER c. semimembranosus The __________ contain higher concentrations of Type I muscle fibers due to the postural requirements of the tissue. a. gluteus medius b. rectus abdominis c. rhomboids d. hip flexor - CORRECT ANSWER b. rectus abdominis The forward motion of throwing requires internal rotation and therefore would be accelerated by the ________ muscle. a. infraspinatus b. deltoid c. subscapularis d. teres minor - CORRECT ANSWER c. subscapularis The primary role of the ________ is to increase intra-abdominal pressure through hoop tension to stabilize and support the spine. a. rectus abdominis b. transverse abdominis c. external obliques d. erector spinae - CORRECT ANSWER b. transverse abdominis The concept that energy is transferred across joints to support voluntary movement is termed __________. a. neuromuscular system b. systemic transfer c. kinetic chain d. isotonic acceleration - CORRECT ANSWER c. kinetic chain Which of the following muscles is commonly found to lack proper flexibility; promoting a posterior pelvic tilt as seen in this picture? a. quadriceps b. glutes c. obliques d. hip flexors - CORRECT ANSWER b. glutes Which muscle is responsible for the first 30 degrees of trunk flexion and is targeted during the crunch movement? a. obliques b. iliopsoas c. erector spinae d. rectus abdominus - CORRECT ANSWER d. rectus abdominus Plantar flexion of the ankle during running is caused by a concentric contraction of which muscle? a. anterior tibialis b. gastrocnemius c. hamstring d. serratus anterior - CORRECT ANSWER b. gastrocnemius A majority of back injuries from incorrect lifting and movement mechanics occur between which segments of the spine? a. cervical and thoracic b. thoracic and lumbar c. lumbar and sacral d. sacral and coccyx - CORRECT ANSWER c. lumbar and sacral After performing a flexibility screen, it is determined that your client has difficulty moving through a full, functional range of motion at the shoulder joint; with clear limitations in external rotation capabilities. Which of the following exercises may prove difficult to perform properly as a result of this flexibility concern? a. chest flys b. standing triceps pushdown c. deadlift d. back squat - CORRECT ANSWER d. back squa
