Question 1

what are the short term responses to korfball in the muscular system?

Answer 1

An increase demand in oxygen, Muscles warm up and become more pliable, an Increase in lactic acid production, use store glycogen

Question 2

What are the short-term effects of korfball on the cardiovascular system?

Answer 2

Increase in heart rate, volume of blood increases, blood pressure increases, redistribution of blood

Question 3

What are the short-term effects of korfball on the respiratory system?

Answer 3

Breathing rate increases, you breathe in more air (volume)

Question 4

What are the long-term effects of korfball on the muscles?

Answer 4

Size increases, they resist fatigue, increase in muscle activation, new blood vessels grow

Question 5

What are the long term effects of korfball on the cardiovascular system?

Answer 5

Heart gets bigger, heart gets stronger, stroke volume increases

Question 6

What are the long term effects of korfball on the respiratory system?

Answer 6

Muscles are stronger to help increase volume of breath, blood vessels increase around alveoli so you can transfer more oxygen & carbon dioxide

Question 7

How long do all three energy systems last?

Answer 7

ATP-PC • 8-10s
Lactic acid • 2m
Aerobic • Indefinite

Question 8

Does the ATP-PC system require oxygen?

Answer 8

The ATP-PC system does not require oxygen to produce energy as it uses stored ATP in the muscles

Question 9

When would you use the ATP-PC system in korfball?

Answer 9

The system provides a short burst of energy and could be used in korfball for when you want to rebound the ball, quickly intercept the ball or jump up to catch the ball

Question 10

What are the waste products of all three energy systems?

Answer 10

ATP-PC • none
Lactic acid • Lactic acid
Aerobic • carbon dioxide

Question 11

Does the lactic acid system require oxygen to produce energy and what does it used to produce energy?

Answer 11

It does not require oxygen. It uses glucose / glycogen stored in the blood and liver to produce energy

Question 12

What does the lactic acid system cause?

Answer 12

Soreness in the muscles due to acid buildup and also causes fatigue

Question 13

When do you use lactic acid system during korfball?

Answer 13

During korfball you use the lactic acid system when you need energy to pace yourself when you’ve used all your stored ATP. An example of when you use it is when you run up and back the court to follow your player

Question 14

What does the aerobic energy system require to produce energy?

Answer 14

Oxygen as well as glycogen

Question 15

What does the aerobic energy system used to produce energy?

Answer 15

Carbohydrates from your food

Question 16

when do you use the aerobic energy system during korfball?

Answer 16

Throughout the whole game
