Components of Fitness and principles of training


Components of physical fitness

� Aerobic Endurance � Muscular Endurance � Flexibility � Speed � Muscular strength � Body composition


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: � Aerobic Fitness � Cardiorespiratory Endurance � 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.

�  Last the duration of the game

�  Can perform more effectively during later stages when others are tired

�  (E.g.)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


Speed: Definition

�  “Distance divided by time taken.”

� Measured in m/s (metres per second) �  Quicker you run = faster speed

� Types of speed: �  Accelerative �  Pure �  Speed Endurance


Types of speed

�  Accelerative �  Covering a distance of up to

30 metres

�  Pure �  Distance up to 60 metres

�  Speed Endurance �  Short recovery periods in-

between 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 � Player scores a try


Muscular Strength: Definition

�  “Maximum force (Kg or N) that can be generated by a muscle or muscle group”



� 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”



�  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 their feet for the 26 mile race
