Point the toes

Question 11

What is the role of antagonistic pair in muscle movement?

Answer 11

2 muscles that work together to produce movement

Question 12

What is the role of agonist in muscle movement?

Answer 12

The muscle that contracts and shortens to make the movement happen

Question 13

What is the role of antagonist in muscle movement?

Answer 13

The muscle that relaxes and lengthens to allow the movement to happen

Question 14

What is the role of fixator in muscle movement?

Answer 14

A muscle that holds a joint in place to support a movement at a different joint

Question 15

Give examples of antagonistic pairs

Answer 15

Hamstring and quadriceps

Biceps and triceps

Question 16

Explain the antagonistic pair when you flex your elbow

Answer 16

The bicep is the agonist and the tricep is the antagonist

Question 17

Explain the antagonistic pair when you flex your knee

Answer 17

The hamstrings are the agonist

The quadriceps is the antagonist

Question 18

Short term effects of exercise on muscular system

What happens whilst we are exercising

Answer 18

Increased muscle temperature
Lactic acid production
Fatigue

Question 19

Long term effects of exercise on the muscular system

The adaptations our body makes as a result of regular training

Answer 19

Hypertrophy (muscles get bigger and stronger)
Increased muscular strength
Increased muscular endurance 
Increased resistance to fatigue
Increased capillarisation to muscles
