Question 1

What are the 12 specification muscles and their location?

Answer 1

• Gluteus maximus (bottom)
• Hamstring (back upper leg)
• Gastrocnumius (calf)
• Latissimus dorsi (side of the core)
• Tricep (back upper arm)
• Deltoid (shoulder)
• Bicep (front upper arm)
• Guadriceps (fromt upper leg)
• Pectorals major (chest)
• External obliques (side of core)
• Tibialis anterior (shin)
• Hip flexors (inward side of upper leg)

Question 2

What are the 12 specification muscles function?

Answer 2

Gluteus maximus - adduct and extend the leg at the hips
Hamstring - flex the leg and the knees
Gastrocnumius - planta-flexion at the ankle.
Latissimus dorsi - pull your arms down at your shoulders
Tricep - extend the arm at the elbow
Deltoid - raise the arm in all directions
Bicep - flex the arm at the elbows
Guadriceps - extend the leg at the knee
Pectoralis major - adduct the arm at shoulder
External obliques - flex and rotate the spinal collumn
Tibialis anterior - dorsi flexion at the ankle
Hip flexors - flex the hip

Question 3

What are antagonistic pairs?

Answer 3

Muscles that work together to create a movement, one muscle contracts (agonist) while the other one relaxes (antagonist).

Question 4

Name the antagonistic pairs.

Answer 4

• Deltoids and pectorals
• Triceps and biceps
• Gluteus maximus and hip flexors
• Quadriceps and hamstrings
• Tibialis anterior and gastrocnemius

Question 5

What are voluntary and involuntary muscles?

Answer 5

Voluntary - muscles under your control
Involuntary - muscles not under your control

Question 6

What are the muscle fibres?

Answer 6

Type 1 - Slow twitch muscle fibres suited for low intensity
Type 2a - Fast twitch muscle finres used for anaerobic work
Type 2x - Similar to 2a but used to generate force
