muscle strengthening

Question 1

what is strength?

Answer 1

• maximum force of contraction from a muscle

Question 2

what is power?

Answer 2

• speed/ rate of a contraction
  force x distance

Question 3

what is endurance?

Answer 3

• amount of quality contractions which can be sustained for a period

Question 4

what is resistance?

Answer 4

• form of exercise to help build strength in the muscle
• can be sustained contraction

Question 5

what is the oxford muscle scale? what is the scale?

Answer 5

• used as an objective marker to assess muscle strength
• 0 to 5

Question 6

what is 0 indicative of on the oxford muscle scale?

Answer 6

• no contraction

Question 7

what is 1 indicative of on the oxford muscle scale?

Answer 7

• flicker/ visible contraction without movement of the limb

Question 8

what is 2 indicative of on the oxford muscle scale?

Answer 8

• movement of the limb with no gravity

Question 9

what is 3 indicative of on the oxford muscle scale?

Answer 9

• movement against gravity no resistance

Question 10

what is 4 indicative of on the oxford muscle scale?

Answer 10

• movement against gravity and some resistance

Question 11

what is 5 indicative of on the oxford muscle scale?

Answer 11

• normal
• against gravity and full resistance

Question 12

what is used in early rehabilitation and why? what does it eliminate?

Answer 12

• movement produced by an external force
• maintains range of movement
• gravity eliminated

Question 13

what is active assisted? what does it allow?

Answer 13

• movement is part of external forces but with voluntary muscle action
• increases range of movement
• allows individual to maintain control

Question 14

what is active? how is it performed?

Answer 14

• voluntary action and full initiation from the individual
• performed with or without equipment

Question 15

what does stretching target? what is it used for?

Answer 15

• targets structures for lengthening position
• used as prevention of injury
• used for mobilisation of soft tissue

Question 16

what four factors need to be considered when stretching?

Answer 16

• speed of movement
• range of movement
• resistance to movement
• levers/ starting position

Question 17

what is considered regarding speed of movement?

Answer 17

• performing an exercise slowly requires postural control
• increased speed requires greater range of movement

Question 18

what is considered regarding range of movement?

Answer 18

• muscles are strongest at mid- range
• weaker at outer range

Question 19

what is considered regarding resistance to movement?

Answer 19

• applied resistance, free weights, body weight, resistance bands, machines, static force

Question 20

what is considered regarding levers/ starting position?

Answer 20

• lengthened lever leads to high load
• levers can be shortened and resistance can be applied for strength

Question 21

what are the three types of contractions?

Answer 21

• isometric
• concentric
• eccentric
