Pe Paper 1 Flashcards
What is the purpose of the cardiovascular system?
The cardiovascular system transports blood, nutrients, gases, and wastes throughout the body.
Example: It helps deliver oxygen to tissues and remove carbon dioxide.
What are the components of the cardiovascular system?
The main components are the heart, blood vessels, and blood.
What is aerobic exercise?
Aerobic exercise is physical activity that improves the efficiency of the body’s cardiovascular system.
Example: Running, swimming, and cycling are forms of aerobic exercise.
What is anaerobic exercise?
Anaerobic exercise is high-intensity activity that lasts for a short duration and does not rely on oxygen.
Example: Weightlifting and sprinting are forms of anaerobic exercise.
What is the role of the respiratory system?
The respiratory system is responsible for gas exchange, bringing oxygen into the body and expelling carbon dioxide.
What is the function of the skeletal system?
The skeletal system provides structure, support, and protection to the body, and facilitates movement.
What is flexibility?
Flexibility is the range of motion around a joint.
Example: Stretching exercises can improve flexibility.
What is muscular strength?
Muscular strength is the amount of force a muscle can produce.
Example: Lifting heavy weights builds muscular strength.
What is muscular endurance?
Muscular endurance is the ability of a muscle to sustain repeated contractions over time.
What is body composition?
Body composition refers to the proportion of fat and non-fat mass in the body.
What is Circuit Training?
A series of exercises completed for a certain amount of time, one after the other, developing aerobic and anaerobic respiration.
What is Continuous Training?
Exercises the body at a moderate rate, keeping the pulse at a constant level with NO rest.
What is Cross Training?
Combines a combination of training methods into one session.
What is Weight Training?
Involves shifting weight to increase the strength of muscles, using a programme of repetitions and sets.
What is Interval Training?
Periods of high intensity work followed by periods of rest.
What is Fartlek Training?
A combination of fast and slow running which varies in time, distance and intensity.
What is Muscular Endurance?
Ability of a muscle or muscle group to undergo repeated contractions, avoiding fatigue.
What is Power in terms of strength?
The product of strength and speed.
Power = Strength x Speed.
What is Static Strength?
The maximum force that can be applied to an immovable object, with muscle length staying the same.
What is Speed?
The maximum rate at which an individual is able to perform a movement or cover a distance in a period of time.
What is Cardiovascular Endurance?
The ability of the heart and lungs to supply oxygen to the working muscles for a period of time.
What is flexibility?
The range of movement possible at a joint.
What is agility?
The ability to move and change direction quickly (at speed) while maintaining control.
What is balance?
The ability to keep the body stable by maintaining the centre of mass over the base of support.
What is coordination?
The ability to use two or more different parts of the body together, smoothly and efficiently.
What is reaction time?
Time taken to initiate a response to a stimulus.
What is health?
A state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.
What is fitness?
The ability to meet, or cope with, the demands of the environment.
What is Dynamic Strength?
The amount of force that can be exerted repeatedly by a muscle or muscle group.
What is Maximal Strength?
Greatest force that is possible in a single maximum muscle contraction.
What is Strength?
The ability to overcome a resistance. There are 4 types: Maximal, Explosive, Static or Dynamic.
What is Explosive Strength?
The amount of force exerted in one quick muscle contraction.
