modules 5-6 growth and development and flexability Flashcards
what is the O-scale?
for individual physique assessment
used to replace the use of body fat predictions
general decription of o-scale is made of
adiposity (a-rating) - 6 skf
proportional weight (w-rating)
what is the stanine scale
a scale in comparison to the normal distribution
has 9 categories
3 types of physiques
balanced, adiposity or weight dominant
weight dominant physique
(a rating) is less that W rating
balanced physique
a and w rating are equal
adiposity dominant
a is greater than w rating
when the subject is moderately atheletic on the o-scale what happens
the W rating exceeds the a ratings because of more muscle mass
what does the Canadian society of excerise physiology (CSEP) Physical activity training for health (path) do?
assess muscular strength , muscular endurance, flexibility, aerobic endurance and body comp
what did Canadian health and experts do to skinfold measurements
removed them from assessment
what does the candian socities body comp analysis consist of
BMI
waist circumference
BMI from growth chart
BMI category
BMI risk
BMI WC risk
what is arthrology
study of joints
what is a joints function
provides stability or mobility
fibrous joints
fixed
two bones united that have no movement
cartilaginous joints
slightly moveable
joints united by cartilage
Synovial joints
freely moveable
majority of joints
synovial fluid allows for lubriation and movement
eg: knee
ligaments
strong fibrous tissue that attach bones to eachother
help resist abnormal movements of the joints
- not highly elastic
tendons
bands of dense fibrous connective tissue that attachg muscles to bones
Bursae
small pouch filled with synovial fluid that provides a cushion to structures rubbing against eachother
Tendon sheath
modified bursa that surrounds and lubricates the tendons of muscles
mostly in wrists and ankles
describe the shoulder joint
a combination of joints
for full range of motion requires mutiple joints
generally refered to as the glenohermal joint - a ball and socket joint
most shoulder dislocations are caused by
an outstretched arm
describe the hip joint
very stable
ball and socket joint
stronger than the shoulder
describe the knee joint
largest most complex joint
what does cartilage do
provides a cushion between bones
how many ligaments make up the ankle joint
4 - main ligaments
what is the sagittal plane
the plane that goes through the body dividing it into left and right
what is coronal plane
the plane going through the body vertically divding it into front and back
transverse plane
horizontal plane that divides the body upper and lower
vertical axis
through middle of body
flexion
results in decrease in the angleof 2 bones
extention
increase angle between two bones
abduction
movement of a limb away from the midline of the body
