left atrium?
A Aorta

C Pulmonary vein
D Vena cava
pulmonary vein

A Sternocleidomastoid and abdominals
B Sternocleidomastoid and deltoids
C Sternocleidomastoid and intercostals

Define muscular endurance.
Use an example of a sporting action in your answer.
- Ability of the muscle or muscle group to undergo repeated contractions, avoiding fatigue (1)
- Ability of the muscles or muscle group to contract over a period of time (1)
- Press ups (1)
- Sit ups (1)
Justify why muscular endurance is an important component of fitness needed for a
games player to perform effectively.
[4 marks]
- Games are usually played over a long period of time (1)
- Muscular endurance allows the delay of the onset of fatigue (1)
- Performers are able to perform at optimal levels for longer (1)
- Muscular endurance allows a games player to increase their capacity to train for longer periods of
time This will result in increased levels of cardiovascular endurance
Identify lung volumes A and B in Figure 1.
tidal volume and Inspiratory reserve volume
In Figure 1, what would happen to lung volume A during exercise?
it would increase
Justify your answer to Question 7.2.
Depth of breathing increases (due to the chest cavity expanding)
* More oxygen needed (in order to sustain exercise)
Define inhalation and describe how it takes place at rest.
Refer to the intercostal muscles, rib cage and diaphragm in your answer
- Inhalation (inspiration) is the intake of air into the lungs
- Diaphragm contracts and flattens (moves downwards) (1)
- Intercostal muscles contract (1)
- Rib cage moves up and out or chest cavity becomes larger (1)
- Molecules (of air) move from high pressure to low pressure (1)
Identify the type of muscular contraction taking place in the legs in Figure 2
isometric
Justify your answer to Question 8.1.
muscle stays the same length
Name two major muscles that allow the foot to move at the ankle
gastrocnemius and tibialis anterior
Name two bones found at the elbow.
humerus and radius
Name the type of synovial joint at the elbow.
hinge joint
Name three structures of a synovial joint that help to prevent injury
bursae
synovial fluid
joint capsule
State four reasons why Michael should test his levels of fitness before starting his
12-week training programme
- To identify his strengths and weaknesses
- To set goals/targets (1)
- To help with the monitoring of his improvement
- To provide variety to his training programme
Identify four long-term effects of exercise.
improve speed
improve muscular endurance
improve stamina
build cardiovascular endurance
Define circumduction.
Use an example of a sporting action in your answer.
- Turning or circular motion around a joint
- Performing a serve in tennis
Name the type of joint where circumduction can take place
ball and socket
What is the role of the valves in the veins?
to prevent backflow
identify two features of the structure of arteries. Explain how each feature helps the
arteries to perform their function.
Small lumen allows blood to travel quickly away from the heart
* Thick muscular walls allow blood to travel under high pressure
Identify the joint action taking place at the knee as the basketball player moves from
A to B.
