State the fitness test shown in the diagram.

Identify the movement at the hip on moving from position A to position B.

Explain the mechanics of inspiration for an athlete completing an aerobic fitness test.

sit & reach test;

flexion;

diaphragm and <external> intercostal muscles contract <more forcefully>;

causing the rib cage to move <further> upwards and outwards;

with assistance of the accessory muscles, eg deltoids, pectoralis;

therefore increasing the thoracic volume;

therefore reducing the thoracic pressure;

causes air to rush in <faster due to a greater pressure difference>;

increase of the depth of inhalation <per breath>;

increase of the frequency/rate of inhalation <per minute>;

Award [3] max if the student does not refer to the effect of exercise on the mechanism of inspiration.
