Reduction in ranges of voluntary movements.

Question 2

Define Strength?

Answer 2

The ability of a muscle to produce force.

Question 3

Define Maximum Strength?

Answer 3

Force generated in a single maximal voluntary contraction.

Question 4

Define Absolute Strength?

Answer 4

Force generated irrespective of body weight.

Question 5

Define Relative Strength?

Answer 5

Force generated relative to bodyweight.

Question 6

Define Elastic Strength?

Answer 6

Force generated at high velocity power.

Question 7

Define Strength Endurance?

Answer 7

Force generated for sustained or repeated muscle action against a sub maximal resistance.

Question 8

What is Tensile Strength?

Answer 8

The maximal amount of stress or force that a structure is able to withstand before tissue failure occurs.

Question 9

What are the factors affecting muscle strength?

Answer 9

Muscle Size.
Number and size of motor units.
Type of Muscle contraction.
Length of muscle.
Angle of pull.
Velocity of muscle action.
Integrity of joint/muscle structure.
Blood supply to the muscle.
