1. The organizational of fibers within a muscle (architecture) defines the performance capacity of that muscle.
A. True
B. False
2. Muscles are exposed to length changes and velocities during movement, both of which do not change absolute force production.
A. True
B. False
3. During the squat exercise, the gluteus maximus and adductor magnus exert similar maximum extension torques at the hip in the sagittal plane, despite the fact that the gluteus maximus has a larger PCSA. This is due to:
A. The force generating capacity of the gluteus maximus is compromised due to fewer sarcomeres
B. The gluteus maximus retains its ability to generate hip extension as the hip is flexed
C. The adductor magnus has a larger hip extension moment arm when the hip is flexed
D. All of the above
4. Which hip muscle should be assessed when hip abduction weakness is suspected?
A. Gluteus maximus
B. Hamstrings
C. Adductor magnus
D. Gluteus medius
5. Overloading the muscle for hypertrophy is most efficiently accomplished at relatively short lengths and during concentric exercise.
A. True
B. False
