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 Fitness
2. Cardiorespiratory Endurance
3. Cardiorespiratory Fitness

Cardiorespiratory System

Made from:
Cardiovascular system (Circulatory
system - Heart, Blood and Blood Vessels)
 AND
 Respiratory system (Lungs and airways)

Cardiorespiratory system

Breathe oxygen in

Nutrients and oxygen transported around
the body

Removes waste (E.g.) Carbon Dioxide
Why it’s important in Sport

Useful 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 sport

Needed 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 sport

Can 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.
2.
3.
Accelerative
Pure
Speed Endurance
Types of speed
Accelerative (you start
moving)
 Covering a distance of up to
30 metres

Pure (your maximum speed)
 Distance up to 60 metres

Speed Endurance
 Short recovery periods inbetween sprints

Why it’s important in sport

100 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 sport

Sprinter 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
