Strengthening

Question 0

Key elements of muscle performance

Answer 0

Strength
Endurance
Power

Question 1

Muscle performance

Answer 1

The ability of a muscle to do work.

Question 2

Strength

Answer 2

The ability of contractile tissue to produce tension and hence force.

Develops hypertrophy and increases muscle fibre recruitment.

Functional or anatomical.

Question 3

Functional strength

Answer 3

The ability of the neuromuscular system to produce, reduce or control forces during functional activities.

Question 4

Power

Answer 4

The speed and strength of movement.

Force x distance/time = rate of performing work.

Question 5

Power training

Answer 5

Explosiveness. Involves strength and speed.

Greater intensity, greater contraction -> greater mm power

Question 6

Endurance

Answer 6

Ability to perform low intensity, repetitive or sustained activities over a prolonged period of time.

Question 7

Overload principle.

Answer 7

Keep pushing up against barriers

Question 8

SAID principle

Answer 8

Specific Adaptation to Imposed Demands.

The body will adapt to the specific demands placed on it. So training should be specific

Question 9

Muscle Setting

Answer 9

A form of isometric training using less than 70% max force.

Maintains mobility between fibres, decreases pain. Realigns fibres and prevents reinjury

No strength gain.

Question 10

Advantages and disadvantages if isometrics:

Answer 10

Advantages: no joint motion so good for early rehab. Delays atrophy after immobilization. May decrease inflammation. Neural association maintained. Fast. Cheap. Easy.

Disadvantages: multiple muscle angles required

Question 11

Overwork

Answer 11

Progressive deterioration of strength in muscles already weakened by no progressive neuromuscular disease.
