Q

Features of a joint

A

Cartilage- a material which covers the end of each bone to help prevent friction and shock between the joint
Joint capsule- the outer covering of the joint that holds the bones together and seals the joint attached to the outer layer of the bone
Synovial membrane- the inner lining of the joint capsule which produces synovial fluid
Synovial fluid- the fluid which surrounds the joint and acts like ‘oil’. It supplies nutrients to the joint
Ligaments- connect bone to bone
Bursae- cushion between bones and tendons

Q

What are the different types of blood vessels and their functions

A

Artery- carries oxygenated blood away from the heart at HIGH PRESSURE
Vein- carries deoxygenated back into the heart at LOW PRESSURE
Capillary- carries blood to and from body cells

Q

What do valves do?

A

Valves allow blood to flow in the correct direction (prevent back flow)
They close if blood starts to flow in the wrong direction

Q

Redistribution of blood flow

A

Vasoconstriction- blood vessels are constricted to make SMALLER. When start exercise the nervous system sends signals to the blood vessels. These signals cause the blood vessels thats supply the inactive areas to constrict, reducing the blood flow
Vasodilation- blood vessels dilate to make them BIGGER. When start exercise the nervous system sends signals to blood vessels. Signals cause the blood vessels that supply the active areas to dilate. This increases the blood flow to the active areas therefore is receives more nutrients and blood

Q

What is anticipatory rise?

A

An increase in heart rate due to the release of adrenaline. The body detects this and increases heart rate to increase 02 delivery in preparation for exersize

16
Q

What is residual volume?

A

Amount of air left in the lungs after maximum expiration

17
Q

What is vital capacity?

A

The greatest amount of air that can be pushed out of the lungs after the deepest possible breath

18
Q

What is the formula for aerobic respiration?

A

Glucose + Oxygen = Energy + CO2 + Water

19
Q

What is the formula for anaerobic respiration?

A

Glucose = Energy + Lactic Acid

20
Q

What is EPOC?

A

EPOC stands for Excess Post Oxygen Consumption
It is needed to repay oxygen debt
EPOC is the additional amount of 02 consumed after anaerobic exercise during the recovery period, above what would normally be consumed at rest.
It involved deeper and quicker breathing

21
Q

What are the types of training?

A

-Fartlek
-Interval
-Weight Training
-Continuous
-Circuit
-Plyometrics

22
Q

What is Fartlek Training?

A

Training on different intensities and terrains and gradients.
This is useful to team games however it is too easy to skip hard bits
-Netball
-Football
-Rugby

23
Q

What is Interval Training?

A

Interval Training is training at high intensity followed with periods of rest.
This improves speed, power and strength and it’s easy to set up
However lactic acid and EPOC can build up
-200m sprinter

24
Q

What is weight training?

A

Form of training that uses progressive resistance against a muscle group.
This is easy to set up and develops power and strength.
However it risks injury and requires spotters for safety
-Weights

25
Q

What is continuous training?

A

Steady but regular pace at moderate intensity for at least 20 minutes.
This improves muscular endurance and it’s good for losing weight.
However it is very boring and doesn’t improve anaerobic fitness
-swimming
-running
-cycling

26
Q

What is circuit training?

A

Working at different stations to avoid fatigue
This targets lots of different muscle groups and minimal equipment is needed
However it required lots of motivation

27
Q

What is plyometrics?

A

Short explosive movements (box jumps)
This improves power and is easy to set up.
However you could get injured if it’s not performed correctly.
-volleyball
-basketball
-hurdles

28
Q

What are the principles of training?

A

USE THE SPORT ANAGRAM
-Specificity
-Progressive
-Overload
-Reversibility
-Tedium (bordem)

29
Q

What is specificity?

A

Making training specific to the sport being played and the muscles being used.

30
Q

What is progressive overload?

A

Gradual increase of the amount of overload so that fitness gains occur but without the potential for injury. Overload is the gradual increase of stress placed upon the body during exercise training

31
Q

What is reversibility?

A

Losing fitness levels when you stop exercising.
Fitness levels decrease as a result of injury.

32
Q

What is tedium?

A

Boredom that can occur from training the same way every time. Variety is needed.
To prevent it, also use different types of training.

33
Q

What are the principles of training?

A

USE THE FITT ANAGRAM
-Frequency: how often you train
-Intensity: how hard you train
-Type: the specific method
-Time: the length of training session.

34
Q

What are the training zones?

A

Maximum heart rate- 220-age
Aerobic training zone- 60-80% of max heart rate
Anaerobic training zone-80-90% of max heart rate
Training threshold - the actual boundaries of the target zones.

35
Q

Planes and axes notes!

A

They divide the body into 2

The frontal plane divides the body into front and back

The transverse plane divides the body into top and bottom

The Sagittal plane divides the body into left and right

Longitudinal axis goes through the top of your head.

Sagittal axis goes right through belly button

Transverse axis goes right through hip

36
Q

Levers notes

A

Made up of a fulcrum resistance and effort

Fulcrum is where you see the bend (joint)

Effort is the muscle that contracts

Resistance (load) is what you are lifting.

37
Q

What are the aspects of fitness?

A

Agility
Balance (static and dynamic)
Cardiovascular endurance
Coordination
Flexibility
Muscular endurance
Reaction time
Speed
Strength

38
Q

DIFFERENT TYPES OF LEVERS

A

FIRST CLASS LEVER- FULCRUM IS IN THE MIDDLE OF THE EFFORT AND LOAD. EG- A HEADER IN FOOTBALL

SECOND CLASS LEVER- THE LOAD IS IN THE MIDDLE OF THE EFFORT AND FULCRUM. AN EXAMPLE IS STANDING ON TIPTOES

THIRD CLASS LEVER- THE EFFORT IS IN THE MIDDLE OF THE FULCRUM AND THE LOAD. AN EXAMPLE WOULD BE A BICEP CURL
