Question 1

Isometric exercises for Muscle Strength, Power and Endurance

Answer 1

same length. Muscle remains at same length throughout contraction.
* May be more appropriate in early stages post injury/surgery or when there is a specific limitation in ROM
* Can elicit blood pressure changes – care with breath holding
* Strength changes specific to the angle of contraction
* 2-6 sec holds

Question 2

Isotonic exercises for Muscle Strength, Power and Endurance

Answer 2

Most commonly prescribed contraction type
* Speed can vary through the ROM
* Involves concentric and eccentric contractions
* Can limit ROM if required

Question 3

Isokinetic exercises for Muscle Strength, Power and Endurance

Answer 3

same speed

• The speed of the movement remains the same throughout the range.
• Need to change the resistance constantly to allow this so specialised equipment
  is required (used more for research or elite sport typically)
• Good for assessing power
• Very reliable measure
• Isolated to one joint so not functional

Question 4

Closed Chain Exercises

Answer 4

exercises performed in weight bearing
- patient must be PWB to FWB
- more functional

Question 5

Open Chain Exercises

Answer 5

exercises performed in non weight bearing
- Good if patient NWB

Question 6

Bilateral Exercises

Answer 6

• requires PWB or FWB

Question 7

Unilateral Exercises

Answer 7

requires FWB status

Question 8

What does (repetition maximum) RM mean?

Answer 8

1-repetition maximum (1RM):
* is the greatest amount of weight that can be lifted with proper technique
for only one repetition
* Requires experience, motivation and good technique
* Usually do RM testing and predict the 1 RM for the patient

Question 9

strength FITT

Answer 9

freq: 2-3x/week 60-70% 1RM (moderate)
intensity: 40-50% 1RM in older adults
(light)
type: Specific to muscle group,
Antigravity,
Body weight, equipment
time: 2-4 sets, 8-12 reps
Lower rep ranges <6 better
for maximal strength
improvements
2 min rest between sets

Question 10

endurance FITT

Answer 10

freq: 2-3x/week
intensity: <50% 1RM (v.light –light)
type: Specific to muscle group
Body weight, equipment
time: 15 – 25 reps
≥2 sets
30-60 sec rest between sets

Question 11

power FITT

Answer 11

freq: 1-3 x week
intensity up to 60% 1RM(moderate)
[focus on high velocity
movement]
time: 1-3 sets, 3-6 reps, 2-4 mins rest
type: Resistance exercises involving each major muscle group are recommended (8-10 exercises). A variety of exercise equipment and/or
body weight can be used
