Therapeutic Exercise 2

Question 1

Isometric exercise

Answer 1

Force generated without a change in muscle length

Question 2

Isotonic exercise

Answer 2

Contraction generated with the muscle exerting constant tension (muscle movement with a constant load)
Performed against resistance

Question 3

Two types of isotonic contractions

Answer 3

Concentric

Eccentric

Question 4

Isokinetic exercise

Answer 4

Muscular contraction generated with a constant maximal speed and variable load

Question 5

Intensity: goal is increased strength

Answer 5

Lower repetitions (6-12) higher load

Question 6

Intensity: goal is increased endurance

Answer 6

Higher repetitions (i.e. 20+) of a lower intensity load

Question 7

Intensity: goal is increased power

Answer 7

Low repetitions (1-3) of very high intensity load used

Question 8

Volume

Answer 8

Total amount of work performed (# of repetitions x intensity of exercise)

Question 9

Exercise sequencing

Answer 9

• large before small muscle groups
• multijoint before single joint exercises
• high intensity before low intensity exercises

Question 10

Rest interval: high intensity

Answer 10

Longer rest interval (3+ minutes)

Question 11

Low intensity exercise

Answer 11

Shorter rest interval adequate (1-2 minutes)

Question 12

Rest intervals: fitness level

Answer 12

Patients with lower fitness levels may require longer rest intervals than more fit individuals

Question 13

Open-chain

Answer 13

Distal segment moves freely in space

Question 14

Closed-chain

Answer 14

The body moves over a fixed distal segment

Question 15

Delorme protocol (1st, 2nd, 3rd set)

Answer 15

1. 10 reps x 50% 10RM
2. 10 reps x 75% of 10RM
3. 10 reps x 100% of 10RM

Question 16

Oxford technique (1st, 2nd, 3rd set)

Answer 16

1. 10 reps x 100% 10RM
2. 10 reps x 75% 10RM
3. 10 reps x 50% 10RM

Question 17

Overload principle

Answer 17

For a muscle to adapt and become stronger, the load that is placed on it must be greater than what it is normally accustomed to

Question 18

SAID principle

Answer 18

Specific adaptation to imposed demands

The body will adapt to the specific type of training that is utilized
Should mirror training to the desired goal

Question 19

Transfer of training principle

Answer 19

There can be carryover effect from one exercise or task to another

I.e. may see improvement in strength along with muscular endurance

Question 20

Reversibility principle

Answer 20

Adaptations seen with resistance training are reversible if the body is not regularly challenged with the same level of resistance or greater

Question 21

Length-tension relationship

Answer 21

The ability of a muscle to produce force depends on the length of the muscle

Question 22

Maximal muscle force is usually produced at this length

Answer 22

Normal resting length

Question 23

Force-velocity relationship

Answer 23

Speed of a muscle contraction affects the force that the muscle can produce

Question 24

Force-velocity relationship: concentric contractions

Answer 24

Increased speed = decrease in force

Question 25

Force-velocity relationship: eccentric contractions

Answer 25

Increased speed causes increased force of contraction

Question 26

3 common conditions resulting from resistance training

Answer 26

• muscle fatigue
• DOMS
• valsalva maneuver

Question 27

Muscle fatigue

Answer 27

Decreasing ability of a muscle to produce force against a load with increasing repetitions, but is reversible with rest

Question 28

S/s of muscle fatigue

Answer 28

• muscle pain and cramping
• tremors
• slower, jerky movements
• unable to complete full movement pattern, use of substitution patterns

Question 29

S/s of DOMS

Answer 29

• ttp over muscle belly or at musculotendinous junction
• soreness with passive stretching or active mm contraction
• decreased strength/ROM

Question 30

DOMS most often occurs with this type of muscular contraction

Answer 30

Eccentric

Question 31

Valsalva maneuver performed by:

Answer 31

Forcefully exhaling against a closed glottis, nose, and mouth while simultaneously contracting the abdominal muscles

Question 32

Who should be especially careful to not perform the Valsalva maneuver?

Answer 32

• cardiovascular disease
• IV disk pathology
• recent eye surgery

*should be avoided with all patients. Exhale through portion of exercise that requires the most effort
