PhysioLec: Muscle Strength and Endurance

Question 1

TRUE OR FALSE: You can test the muscle endurance of the abdominals
using curl-ups.

Answer 1

True

Question 2

TRUE OR FALSE: Long parallel fiber muscles, such as gastrocnemius, are
high force-producing muscles.

Answer 2

True

Question 3

TRUE OR FALSE: Resistance training decreases CNS activation and
increases the motor unit synchronization for increases
in firing rates.

Answer 3

False

Question 4

TRUE OR FALSE: Resistance training may induce increased tendon and
ligament strength as well as increased bone mineral
content to resist fractures.

Answer 4

False

Question 5

TRUE OR FALSE: One-repetition maximum is used for isometric muscle
strength testing.

Answer 5

True

Question 6

TRUE OR FALSE: Isometric training pinpoints an area of muscle
weakness and strengthens the appropriate joint angle
in the ROM.

Answer 6

True

Question 7

TRUE OR FALSE: Testing the strength knee extensors of the patient can
be assessed using a hand-held dynamometer.

Answer 7

True

Question 8

TRUE OR FALSE: Growth takes place when there is an increased number
and size of myofibrils per muscle fiber.

Answer 8

True

Question 9

TRUE OR FALSE: For a concentric contraction of a biceps, an increase in the speed of contraction will produce an increase in
force.

Answer 9

False

Question 10

TRUE OR FALSE: Your athletic patient can perform high repetition of
biceps curl with only 2lbs dumbbell but can only do few
repetitions near their 1-repetition maximum.

Answer 10

True

Question 11

TRUE OR FALSE: Muscle size changes are apparent as early as 2 weeks
of training.

Answer 11

False

Question 12

TRUE OR FALSE: Type I fibers have low force production but resistant to
fatigue.

Answer 12

True

Question 13

TRUE OR FALSE: Isometric action can generate force despite
lengthening and shortening of a muscle producing no
external work.

Answer 13

False

Question 14

TRUE OR FALSE: Resistance training can decrease lean muscle mass and
body fat.

Answer 14

False

Question 15

TRUE OR FALSE: A decrease in muscular force with exercise training
provides the primary stimulus to initiate the process of
skeletal muscle growth or hypertrophy.

Answer 15

False

Question 16

TRUE OR FALSE: Muscles produce the greatest tension when it is near
or at the physiological resting position at the time of contraction.

Answer 16

True

Question 17

TRUE OR FALSE: Isometric training provides a consistent stimulus for
muscular hypertrophy.

Answer 17

False

Question 18

TRUE OR FALSE: Cardiopulmonary endurance is the number of total
repetitions of muscle action can be done in a given
time.

Answer 18

False

Question 19

TRUE OR FALSE: The initial increase in muscle strength from your patient who had just resistance training for 2 weeks is
due to neural adaptation.

Answer 19

True

Question 20

TRUE OR FALSE: The most visible adaptation to resistance training is
muscle fiber hypertrophy.

Answer 20

True
