Optimum Weight
GCSE PESlide3
Learning objectives…
To identify the meaning of
expected
and
optimum
weight
To understand the meaning of being
underweight, overweight,
overfat
and obese
To evaluate the effect these conditions have on performanceSlide4
Optimum weight…
Everyone’s expected and optimum weight is slightly different…
Expected weight
T
he weight you expect them to be
Optimum weight
T
he weight at which you perform your bestSlide5
Optimum weight…
Your optimum weight depends on 4 things…
Height
The taller someone is, the larger their body – so the heavier you would expect them to be.
2) Bone structure
Some people have a larger bone structure than others. The more bone you have, the higher your optimum weight will be.
Muscle girth
This is your measurement of the circumference of your muscles when they’re flexed. Some people naturally have more muscle than others – which means they will have a higher optimum weight.
Gender
Men and women naturally have different body compositions. Men usually have larger bone structure and more muscle than women, so they generally have higher optimum weights.Slide6
Match up exercise!
Underweight
Obese
Overfat
Anorexic
Overweight
Try your best to match up the following key words with their definitions!
An eating disorder where sufferers believe they are fat and starve themselves to lose weight
Having more body fat than you should

Examples…
A jockey may be underweight compared to his
expected weight
, but at his
optimum weight
for his sport – the less he weighs, the faster his horse will be able to run
A boxer may be overweight compared to his
expected weight
, but at his
optimum fighting weight
Can you think of any other examples from sport where expected and optimum weight may vary? Write a paragraph in your book explaining this.Slide9
How do these conditions affect performance?
Have a think with your partner about how these conditions can affect performance in sport…
Overweight
Overfat
/obese
UnderweightSlide10
Overweight…
Being overweight means you are carrying extra weight around. This means that you can get tired more easily, so you might not be able to do endurance sports like long distance running.Slide11

or obese can also limit your flexibility and movement. The stress the excess weight puts on the body and the heart can make doing exercise potentially harmful.
Why would exercise be harmful...?
What physical changes may of occurred that could cause harm?Slide12

What conditions can this lead to?
How would you explain anorexia? How would it effect an individual?Slide13

Which one of the following correctly identifies four factors affecting optimum weight?
Bone structure, gender, muscle girth, height
Height, diet, muscle growth, body composition

Which one of the following statements is correct?
Obese – a term meaning very overweight
