Growth and maturation Flashcards
Why study somatic growth?
Knowledge-processes, timing, tempo Status- progress and tracking Compiling reference values Interpretation of human performance Understanding the effect of training /detraining/disease Profiling- talent identification Know the child is growing normally Study the effect of maturation on motor development
What are the determinants of somatic growth?
Genotype
Nutrition and energy balance
Activity level
Endocrine system
What is growth?
An increase in body size
Variable process and end point
Continues throughout life
What is maturation?
Process of becoming fully mature
Variable process with defined end point
Sexual, dental and skeletal
What are the methods to assess body composition, size and shape in young people?
Stretch stature (height) Densitometry DXA BIA Skinfolds
What is recumbent length and how i it measured?
Measured from soles of the feet to the head
Used until the child can stand
When is recumbent knee height used?
To estimate stature in elderly or disabled populations
In children where is the centre of gravity and what effect does this have?
Higher because a large proportion of their weight is in their upper body
They are less stable
Where is the centre of gravity in adults?
53-59% of their total height
What BMI is overweight and obese?
> 25
>30
What are the issues with using reference curves?
Fail to capture the wide variation present in the growth patterns of normal healthy children
Growth trajectory of each child varies depending upon the tempo and timing
What factors need to be analysed when selecting a growth curve?
Sex
Age
What is advised to do when using reference curves?
Use repeat measures over time
Can anyone take anthropometry tests and why?
No
You need years of training
Good understanding
What age range is waist circumferance used?
3-19 year olds
