What is the first thing you think
of when thinking about Body
Composition?
WEIGHT?
The easiest way to get an idea of your body composition is by
calculating you Body Mass Index (BMI). This is done by dividing
weight in kilograms by height in metres squared (kg/m2).
TRY IT!!
BMI =
( kg/m² )
weight in kilograms
————————————
height in meters²
..\BMI calculator.xlsx
This method is used by the NHS and often insurance companies to
see if applicants for life insurance are a safe risk, ie. are they a
healthy weight for their height.
The following scale is given as a guideline to define healthy and
unhealthy BMI measurements:
Healthy BMI=18.5 to 25
BMI below 18.5 = underweight
BMI above 25 = overweight
BMI below 17.5 = near anorexic
BMI higher than 30 = obese
BMI above 40 = morbidly obese

Task
(and finished for homework)
HRE aspects are usually needed in combination,
more of one, less of the other...
1. Choose the activity you are going to base your
PEP on (your best sport) and list the relevant
health-related aspects in order of importance.
2. Now explain why it is important for that sport.

SKILL
What does it mean to you?
More specifically, ‘Skill Related Fitness’

of Skill-Related
Fitness
Learning objectives
Learning objectives
To know the 6 components of Skill Related Fitness:
agility
balance
coordination
power

and speed.
Some of you may even understand how and why these elements of
skill related fitness are important to different sports.

In order to be good at gymnastics you need to
be flexible...ie. Flexibility as an aspect of
Health Related Exercise.
However, Flexibility alone is not good enough, is
it?

• Copy down the definitions for the following:
Agility
Balance
Coordination
Power
Reaction time
Speed.
Agility
A 100m race does not require
agility, but doing a floor routine
in gymnastics does. A rugby
player running for the try line
needs agility to dodge the
defenders. A fencer and
badminton player need agility
to change their body position
quickly.
Balance
Balance can be:
Static – for example, standing on one leg.
Dynamic – for example, keeping your
balance on a bike as it goes round a corner.
What type of balance
does a surfer need?
Balance
Both types of balance are needed in some
sports.
Can you think of any?
Coordination
Coordination allows you to produce complex
actions from a number of smaller
movements.
For example...Stuart Broad (England Cricket)
is right armed bowler, but bats left handed.
© EMPICS Ltd
Generally people are more coordinated on
one side of their body that the other. People
who are right handed are often right footed.
However, this is not always the case.
Coordination
Just like balance, there are different types of coordination:
•
•
Hand-eye coordination – Racquet games in order to strike the ball or shuttle
correctly
Goal keeper to catch a shot or punch the ball out.
•
Foot-eye coordination – Needed to strike the ball to pass, or shoot in football.
•
Head-eye coordination – Needed to strike the ball with the head in order to
clear a corner of shoot.
•
Other examples.....chest-eye, thigh-eye
Other sports?
Power
power = strength × speed
Power increases as a result of an increase
in strength or speed.
Power is important in explosive events like
throwing and sprinting. For example.
Driving their bodies out of the starting
blocks when the gun fires.
Power is vital to getting a good start in
short races or jumping high in games or for
the high jump. Or the long/triple jump at
the moment of the take off.
Reaction time
Reaction time is the time between
the trigger being pulled , the gun
firing and the athletes starting to run.
However, a stimulus could be anything
from a starting gun to a sudden sidestep by an opponent, or a shout from a
teammate.
For example, how quickly a table tennis player reacts to a wide serve from their
opponent.
The faster they react, the better their chance of making the return.
Speed
Speed includes:
Leg Speed, e.g. Usain Bolt
Hand Speed, e.g. Boxer Joe Calzaghe
Speed of thought, e.g Tennis star
Rafael Nadal
Speed is very important in many sports – it can often be
the thing that separates a good performer from a great
performer.
Mohammed Ali once boasted that he was so fast h could switch off the light and be in bed
before it goes dark.
How important is speed in the following activities?
Rugby
Dancing
Lawn bowls
It is important to understand the
difference between health-related
exercise and skill-related fitness.
