Outline the importance of specificity, accuracy, reliability and validity with regard to fitness testing.• Specificity- When testing fitness it must be specific to the sport. • Accuracy- the instruments used to measure the fitness
component must be accurate. Equipment working properly. • Reliability- the degree to which a measure would produce the
same results from one occasion to another. If we see improvements in fitness tests, improvements must be due to fitness and not because there is something wrong with the reliability of the test. • Tests are unreliable when there is a learning or habituation
effect i.e. a decrease in response to a stimulus after repeated presentation.
• Validity- the fitness test measures what it claims to measure.

What is the role of agonist, antagonist and synergistic muscles in accomplishing joint motion?
• Agonist- mover contracts concentrically i.e. muscle shortens to move the bone relative to the joint.
• Antagonist- during joint movement contracts eccentrically i.e. muscles lengthens
• Synergist- helps agonist by contracting isometrically, i.e. muscle does not shorten but is contracted, to prevent unwanted movements
