Session 12
Session Aim/ObjectivesAim By the end of this learning outcome you will successfully achieve your target grade in the muscular section
of the assignment
ObjectivesBy the end of the session you will be able to:1. Identify the bones, joints and antagonistic muscle pairings
of simple sports exercises
2. Explain the terms eccentric, concentric and isometric muscular contractions
3. Identifying the type of muscular contractions occurring in simple sports exercises
Recap tasks
• Gapped Handout
• List pairs without any notes or prompts
• Yesterdays handout – Agonist/Antagonist

Gapped Handout Answers
• Pectorals / Latissimuss Dorsi• Anterior deltoids / Posterior deltoids• Trapezius / Deltoids• Erector spinae / Rectus abdominus• Right external obliques / Left external
obliques• Hamstrings / Quadriceps• Gastrocnemius / Tibialis anterior• Triceps / Biceps
Agonist or Prime Mover(Biceps contract)
The muscle doing the work (contracting) and creating the movement is called the agonist or prime mover.
Antagonist(Triceps relax)
The muscle which is relaxing and letting the movement take place
is called the antagonist.
Task 1
• Move around the room to analyse 3 exercises
• Complete the blank movement table on the flip chart paper.
• Each member of the group using one colour pen to insert their answers
• 10 minutes allowed
Muscle Contraction
• Isotonic or concentric contraction• Muscle length shortens during
contraction
Muscle Contraction
• Eccentric contraction• Muscle lengthens under tension
Muscle Contraction
• Isometric• Muscle length stays the same
during contraction• Example –holding a press up
position
Task 2
Pairs – decide on and write out a definition for the 3 types of contraction:-
1.Concentric2.Eccentric3.Isometric contractionsExtension task - Look at the diagrams below what type
of contractions is occurring on the agonist and antagonists….?
Press up (upward phase -Upper arms) Sit up (Upward Phase -
Stomach)
Task 3
Using the movement tables you started in task 1…
• Add the type of contractions in the agonists and antagonists for each skill
Extension question….
• What sports skills require isometric muscular contractions?
SummaryObjectives achieved?Can you:1. Identify the bones, joints and antagonistic muscle
pairings of simple sports exercises?
2. Explain the terms eccentric, concentric and isometric muscular contractions?
3. Identify the type of muscular contractions occurring in simple sports exercises?
Next Session the effects of exercise on the muscular system
