What is the main function of the aerobic energy system?
What is the main function of the aerobic energy system?
The aerobic energy system provides the energy for most human activity from birth to death, and is important in recovery from exercise of all intensities.
How does the aerobic energy system differ from the anaerobic energy systems?
How does the aerobic energy system differ from the anaerobic energy systems?
The aerobic system requires oxygen and is very efficient, while the anaerobic systems (lactate system and ATP-CP system) can operate without oxygen and produce waste products like lactate and acid.
What is the relationship between the heart, lungs, and the aerobic energy system?
What is the relationship between the heart, lungs, and the aerobic energy system?
The heart and lungs are important in aerobic activity as they deliver oxygen and fuel to the muscles via the bloodstream.

Study Notes
History and Evolution of Athletics
- Athletics includes competitive events: running, jumping, throwing, and walking.
- Major types of competitions: track and field, road running, cross country running, and race walking.
- Origins dated back to Greece, with possible beginnings in the 10th or 9th century BC.
- First Olympic Games held in 776 BC in Olympia, Greece; featured the stadium footrace.
- Koroibos was the first Olympic winner.
Characteristics and Equipment in Athletics
- Equipment has distinguishable features that can influence performance in different events.
- Long jumpers perform three jumps into a sand pit; longest jump counts.
- In triple jump, athletes perform a hop, skip, and jump.
- Measurement is taken from the nearest mark left in the sand to the jumping foul line.
- Uniformity is crucial; violations can lead to disqualification.
Aims of Jumping Events
- Maximize distance or height; in triple jump, distance of three consecutive jumps is key.
- In pole vault, the use of a pole assists the jump.
Basic Rules in Throwing Events
- Aim for maximum distance; disciplines include shot put, discus, hammer, and javelin.
- Shot, discus, and hammer are thrown from a circle; the javelin is thrown from a runway.
- Foul occurs if an athlete steps out of the designated area during the throw.
- A valid throw lands entirely within the marked zone; athletes must remain in their area until the implement lands.
Nutritional Aspects for Athletes
- Energy measured in calories; varies by food type:
- Bar of Chocolate: 300 calories
- Glass of Milk: 100 calories
- Piece of Bread: 75 calories
- Apple: 50 calories
- Cup of Tea: 5 calories
- Nutrients essential for bodily functions include carbohydrates, proteins, fats, vitamins, and minerals.
Nutrient Types
- Carbohydrates: Key “energy food,” quickly broken down for energy.
- Proteins: Important for growth and repair; made of amino acids.
- Fats: Concentrated energy source; provide twice the energy of carbohydrates, found in animal and vegetable products.
-
Vitamins: Essential in small amounts, contribute to various body processes.
- Fat-soluble vitamins stored in the body.
- Water-soluble vitamins must be consumed daily due to lack of storage.
- Minerals: Required in small daily amounts for health.
