Optimum WeightOptimum Weight• Is a person’s ‘most favourable’ weight.

• Body weight affects sporting performance.

• In some sports it is favourable to be heavier, in others, lighter.

• More generally, people can find out their optimum weight by calculating their BMI or by measuring their wrist girth.

HeightHeight

How would height affect optimum weight?

HeightHeight

Taller people are usually,

although not always,

heavier than shorter people

GenderGender

How would gender affect optimum weight?

GenderGender Men and women have a different body composition

Men tend to have more muscles and larger bones

Therefore males and females have different charts to find their optimum weight

Bone StructureBone Structure

How would bone structure affect optimum weight?

Bone StructureBone Structure Everybody has a different bone structure, sometimes referred to as frame size

Height cannot determine a persons bone structure

Comments such as ‘broad shoulders’ and ‘thick wrists’ refer to the bone structure of a person

Muscle GirthMuscle Girth

How would muscle girth affect optimum weight?

Muscle GirthMuscle Girth As with bone structure, people naturally have different muscle girth

In most cases, muscle girth increases with training

Because muscle weighs more than fat, some BMI index charts will show a performer with a large muscle girth as being overweight

GeneticsGenetics

How would genetics affect optimum weight?

GeneticsGenetics

Body weight and shape are

largely passed on through the

genes from parent to child

The body composition of a

performer is bound by genetics,

but with training, can be changed
