Aerobic Endurance: Definition“Ability of the cardiorespiratory

system to work efficiently. Supplying nutrients and oxygen to working muscles during sustained physical activity”

Also known as:1. Aerobic Fitness2. Cardiorespiratory Endurance3. Cardiorespiratory Fitness

Cardiorespiratory SystemMade from:

Cardiovascular system (Circulatory system - Heart, Blood and Blood Vessels)

ANDRespiratory system (Lungs and

airways)

Cardiorespiratory systemBreathe oxygen in

Nutrients and oxygen transported around the body

Removes waste (E.g.) Carbon Dioxide

Why it’s important in SportUseful so the performer

can “keep going”, without getting tired.

Can perform more effectively during later stages when others are tired. Lots of goals are scored during the last 15 minutes of Football matches

Muscular Endurance: Definition“ Ability of the muscular system

to work efficiently, where a muscle can continue contracting over a period of time against a light to moderate fixed resistance workload”

Why it’s important in sportNeeded for the

muscles to repeat movements over and over again

Without getting fatigued

(E.g.) Tennis player that can maintain serve and groundstrokes during final set

Flexibility: Definition“ Adequate range of motion in all

joints of the body ; the ability to move a joint fluidly through it’s complete range of movement”

Why it’s important in sportCan be useful in

preventing muscle and joint injuries from happening

Allows performers to reach/stretch further

(E.g.) Badminton player being able to reach low down to play a recovering shot. Gymnast performing vaults or routines

Speed: Definition“Distance a person travels

divided by time taken.” Speed = Distance / Time Measured in m/s (metres per

second)

Types of speed:1. Accelerative2. Pure3. Speed Endurance

Types of speedAccelerative (you start

moving) Covering a distance of

up to 30 metres

Pure (your maximum speed)

Distance up to 60 metres

Speed EnduranceShort recovery periods

in-between sprints

Why it’s important in sport100 metre race: Quickest sprinter

gets to the line first

Rugby winger is too fast for the defender

Defender can’t catch them

Muscular Strength: Definition“Maximum force measured in

kilograms (Kg) or Newtons (N) that can be generated by a muscle or muscle group”

Explosive strength (force exerted in one quick, powerful contraction)

Dynamic strength (force that can be exerted repeatedly my a muscle)

Why it’s important in sport

Weightlifter to be able to lift heavy weight

Footballer being strong in a tackle to win the ball from an opponent

Rugby union player using their force in the scrum

Body Composition: Definition“Relative ratio of fat mass to fat-

free mass (vital organs, muscle and bone) in the body”

Why it’s important in sportSprinter would tend to

be a Mesomorph: muscular and powerful to generate speed to get to the line first

Sumo-wrestler is an Endomorph : Large performer to be able to push others out of the ring.

Marathon runners are Ectomorphs to be light on their feet for the 26 mile race
