Higher body fat and lower muscle mass, postural changes and reduced RoM.
No. of functional twitchj fibres decreases so training becomes more difficult
along with risk of osteopenia and osteoperosis.
Staying active reduces the rate of these changes.
Osteoperosis is a disease that lowers the amount of bone mass and deterioration of
bone tissue, leading to enhanced bone fragility and increased risk of fracture.
Regular weight bearing exercise reduces the risk of osteoperosis
Young People (4-16)
Due to puberty in crease in hormones causes the amount of
muscle mass to increase
During growth spurts the amount body fat decreases as it has a l;arger
area to cover.
Skeletal system will develop
with age through growth
spurts and this is usually for
girls between age 10-13 and
for boys between 12-15
Males will have more testosterone and females will produce
more oestrogen, however when pregnant will proiduce more
elastin.,
Muscle does not grow proportionally to the bones so during growth spurts the muscle
becomes stretched and can increase the risk of injury due to flexibility issues and
pulling muscles.
Limb length will change during growth spurts and legs will be in proportional
this is because some body parts grow faster than others and heavy lifting
and high impact exercises should be avoided if injury wants to be avoided.
Pre/Post-Natal
Elastin is produced and abdominal muscles stretch and can cause injury to the abdominal region and pelvic floor area.
Postural changes will occur as the prescence of the baby could cause in some cases
hyperlordosis
Abdominal muscles stretch due to the weight of the baby belong inside of them and make them
susceptible to injury.
ATP
Making ATP in the prescence of oxygen
Making ATP in the abscence of oxygen
CP has a high energy bond like ATP which is broken down by creatine kinase to
release ATP. Very quick and only lasts a very short period of time.

Carbohydrates are converted into energy stores such as glucose and glycogen and are used primarily as an energy
store and used to produce ATP, then fats are used followed by proteins.
To create ATP quickly and effectively t5o be used during exercise.
