28. Javelin
29. 400m race
Explain the importance of each of the energy systems used:
30. In a tennis match

EXTENSION
Choose a sport you are involved in.
 Think of a specific movement / action associated with this sport / activity. This could be a
running, throwing, striking or jumping action, or a common movement, e.g. standing up when
surfing.
1.
List the movements occurring at the wrist, elbow, shoulder, hip, knee and ankle.
2.
List the agonist and antagonist muscles involved at each joint.
3.
Explain in detail the principles of force summation during the action.
4.
Discuss the relative stability of the person during the preparation and execution phase(s) of
the action.
5.
Describe the importance of each of the 3 energy systems in your selected sport / activity,
and also specifically during the phase you have identified.
6.
Describe 5 immediate physiological effects that occur during participation in your activity.
Consider also the warm up phase that may precede the activity.
7.
Describe 5 physiological effects that may occur as a result of a prolonged training
programme, or through involvement in the activity over a period of time. E.g. a person surfs or
goes rock climbing three times a week for 8 weeks.
8.
Describe Newton’s Laws as they apply to your activity. You may need to consider more than
one action / application in your explanation.
9.
Describe how the length of levers may be changed to improve performance in your activity.
10. Consider how a people with a range of body types may be advantaged / disadvantaged in
your activity / sport. Give specific examples and relate this to anatomical features and
biomechanical principles.
1. What movement is occurring at Nadel’s right elbow? Elbow flexion
2. Name the muscle responsible for this movement. Biceps
3. What does the triceps do to allow this movement / action to occur? Relaxes &
lengthens, (then contracts @ end of movement)
1. Muscles work in pairs. What is the name we give to the muscle that causes
movement to occur? Prime mover / agonist
2. What is the name given to the other muscle, that allows the movement/action to
occur? Antagonist muscle
Name the movement occurring at the following joints;
AND the prime mover / agonist muscle responsible:
6. Shoulder Flexion – Anterior deltoid (Antagonist = posterior deltoid)
7. Elbow. Extension – triceps (antagonist = biceps)
8. Left knee Flexion - Hamstrings (antagonist = quadriceps)
For the Irish player name the movement occurring at the following joints;
AND the prime mover / agonist muscle responsible:
9. Right hip Extension – Gluteals (antagonist = Hip flexors)
10. Right knee Extension - quadriceps
11. Right ankle Plantar flexion - gastrocnemius
12. Left shoulder Abduction - trapezius
12. What is the movement occurring at the right wrist of the volleyball player spiking
the ball? Flexion – wrist flexors (antagonist = wrist extensors)
STABILITY
State where the centre of gravity and line of gravity are in the following pictures:
AND describe the relative stability of each person.
13.
14.
15. Explain 3 ways in which the person indicated by the arrow increases their stability?
Wide stance, bend knees = lower cog, keep cog over base of support
“A”
16. Make a statement about the centre of gravity and relative stability of the diver
compared to person “A” Arms raised cog shifts higher, narrow base of support = less
stable
17. To control their forward rotation, the gymnast arches his back and moves his
arms and legs backward (in a position similar to the ‘hang position’ adopted in
the long jump). This is an application of which of Newton’s Laws?
Newton’s 3rd Law = For every Action there is an equal & opposite reaction
SOMATOTYPES:
CONSIDER EACH OF THE FOLLOWING PLAYERS. FOR EACH PLAYER
IDENTIFY AND EXPLAIN AN ANATOMICAL FEATURE AND BIOMECHANICAL PRINCIPLE THAT
COULD PROVIDE AN ADVANTAGE IN TENNIS.
18. Justine Henin smaller person; short levers; fast movements; quick about court;
bring racquet through quickly; smaller person, less weight to carry about court
19. Serena Williams well developed muscles; creates power in shots
20. Maria Sharapova taller, slim person; longer levers to develop power & reach
21. Identify 3 immediate physiological responses to exercise during a game of 3 v 3
streetball. Sweating, Breathing rate Heart rate, vasodilation/vasoconstriction,
shunting of blood to skin (cooling), SV, Q, Ventilation, Systolic BP, …
22. For one of these responses, explain why this occurs.
23. You have been involved in a 6 week training programme for streetball. Describe 3
physiological changes that have occurred over this time. heart size, Resting Hr, SV,
Q, Muscular Changes - muscle size, glycogen stores
24. For one of these responses, explain why this occurs.
25. Look at the sequence of photos showing tennis serve. Describe how maximum
force is generated in the serve.
Develop power through large muscles of back
& torso; followed by shoulder muscles; then
smaller muscles of arm & wrist. Max power /
force generated by using all muscle groups in
correct sequence (larger to smaller), timing
(develop power in sequential muscle groups
when previous group is at peak)
