Strength and power

Question 1

Define strength

Answer 1

The ability to produce force

Question 2

Define power

Answer 2

The product of force and velocity (the ability to produce force quickly)

Question 3

What are the objectives of resistance training?

Answer 3

Weightlifting and powerlifting competitions
Body building
General strength training for fitness and health
Physical therapy for rehabilitation from injury or disease
Sport specific training to maximise sport performance

Question 4

Name the 4 principles of resistance training

Answer 4

Overload
Reversibility
Individual differences
Specificity

Question 5

What is overload?

Answer 5

Stress the body and let it adapt 
Duration 
Frequency 
Recovery 
Exercise type 
Resistance

Question 6

Describe the principle individual differences

Answer 6

Injuries- past injuries affecting them

Biomechanics-differences between people

Question 7

How do you measure strength?

Answer 7

Handgrip tests
1test max
force platforms

Question 8

How do you assess power?

Answer 8

explosive exercises such as sprints

Question 9

Explain the neural adaptations to resistance training

Answer 9

Motor unit synchronisation- nervous system gets better at recruiting motor units. means can recruit more muscle fibres. More force produced

Increased rate coding of motor units- increasing firing rate of motor units

Increased neural drive

Autogentic inhibition- golgi tendon organ gets triggered causes muscle to relax. Muscle no longer producing force. Golgi tendon organ protects the muscle. Muscle protected b y the nervous system

Question 10

Explain the adaptations to resistance training: muscular hypertrophy

Answer 10

Transient hypertrophy- occurs during and immediately after a training session due t interstitial and intracellular oedema (fluid retention)

Chronic hypertrophy- structural changes in the muscle resulting from long term training/. Eccentric (lengthening) contracting are crucial for stimulating protein remodelling in muscle fire
