Fitness components
Identify 2 Health Related fitness components
Muscular Endurance
Muscular Strength
Flexibility
Aerobic Capacity
Body composition
What does ATP stand for?
Adenosine Triphosphate
Where does energy come from?
Food
Carbohydrates, Fats, Protein
Identify the difference between the anaerobic and aerobic energy systems
Anaerobic - without oxygen
Identify a movement which demonstrates muscular power in a game of netball
Rebounding
Explosive take off
Identify 4 Skill Related Fitness Components
Agility
Coordination
Reaction Time
Muscular Power
Speed
Balance
Where is ATP generated?
Mitochondria
Describe how carbohydrates provide energy for the body
Carbohydrates are broken down into glucose.
Glucose is stored as glycogen in the muscles/liver. This chemical energy is converted into mechanical energy to produce movement.
Used for up to 60 minutes of vigorous PA
90-120 minutes of moderate PA
What are the 3 energy systems
ATP-PC system
Lactic acid system
Aerobic system
Identify the order of energy breakdown
1. Carbohydrates
2. Fats
3. Protein
Describe the difference between Health related fitness components and Skill related fitness components
Health-related fitness components are the parts of fitness that help you stay healthy, prevent disease, and live a better quality of life.
Skill-related fitness components are about how well you perform in sports and physical activities.
They are called "skill-related" because they focus on improving specific abilities that help you move quickly, accurately, and efficiently.
True or false:
ATP is the only useable form of energy in the body and cannot be reproduced.
False - resynthesised by our 3 energy systems
Which macronutrient provides the most amount of energy per gram
Fats (37kj)
Carbs (16kj) & Protein (17kj) are half the amount
How long does the ATP-PC system last
A touch player sprinting away from a defensive player in a breakaway try. Determine which type of nutrient would most likely be used by the body as a source of energy.
Carbohydrates
Identify the two most important fitness components for netballers
Agility
Speed
Heat + Energy
A marathon runner who had 'hit the wall' in the last 2km of her race. Determine which type of nutrient would most likely be used by the body as a source of energy.
Protein
How long does the Lactic Acid system last for?
30 sec - 3 mins
How does the ATP-PC system resynthesise ATP
Creatine Phosphate is broken down from creatine kinase (enzyme).
The separated phosphate group attaches to ADP to resynthesise ATP.
Identify a movement skill in netball which replicates balance
Maintaining a stable landing
Maintaining body position when contesting for the ball
Balance on pivoting foot
How is energy released?
The high energy bond between the 2nd and 3rd phosphate groups in ATP is broken
What two body systems make up the aerobic energy system
Cardiovascular and respiratory systems
What is the fuel source for the lactic acid system
Muscle glycogen
A WA sprints repeatedly to receive centre passes.
Which energy system is dominant?
Lactic acid system
