Answer 11

Work in pairs, when one contracts the other relaxes: biceps contracts (agnostics) triceps relaxes (antagonists).

Question 12

Synergists, origins and insertion:

Answer 12

Other muscles that support the agonist = synergists
The tendon of the muscle joins the stationary bone = origin
The tendon of the muscle joins the moving bone = insertion.

Question 13

Fast twitch muscle fibres:

Answer 13

Contraction strength = very powerful
Energy production = anaerobic respiration
Endurance = only work for short periods
Who = sprinters.

Question 14

Slow twitch muscle fibres:

Answer 14

Contraction strength = weaker
Energy production = aerobic respiration
Endurance = can work for long periods
Who = marathon runners.

• straight back
• prevents bone alignment strain
• more room for lungs
