The document discusses muscular-skeletal responses and adaptations to exercise. It describes three muscular responses to exercise: fiber recruitment, force production, and metabolism. It states that greater flexibility at a joint results from skeletal response to exercise. The document lists several muscular adaptations from aerobic and anaerobic training, including increased muscle glycogen stores, muscle fiber hypertrophy, and increased mitochondria. It provides example exam questions about the difference between response and adaptation and identifying muscle fiber types and suitable training methods.

2. Learning Objectives
1) Know and be able to explain the 3 muscular-skeletal
responses to exercise
2) Understand what skeletal response you may see and
why
3) Be able to list the muscular- skeletal adaptations
resulting from both aerobic and anaerobic training

5. Example Exam Question
 The body responds and then adapts to exercise.
 Explain the difference between a response and an
adaptation (4 marks) (2010)

6. Adaptations –
Long term effects of anaerobic training
Long term effects of aerobic endurance training
Increase the stores of muscle glycogen
Decrease the levels of subcutaneous fat deposited within the muscle
Increase the tolerance of the muscles to lactic acid
Increase the myoglobin within the muscle
Increase the size of type 2 muscle fibres (__________________________)
Increase the stores of muscle glycogen
Increase the strength of the connective tissue i.e. tendons and ligaments
Increase the efficiency at which fat can be metabolised
Make type 11b fibres begin to adopt the characteristics of 11a fibres
Increase the size and density of the mitochondria within the muscle
Increase the size of stored potential energy on the muscle such as phosphocreatin
and muscle glycogen
Increase the force that can be exerted by the muscle and the duration for which it can
be exerted

7. Exam Question
Identify the three skeletal muscle fibre types and a
method of training suited to each. For each training
method identified explain one structural adaptation.
