Lab Unit 3: Heath-Carter Somatotype Flashcards
How many components are in the the scale?
Three
What is the range of the ratings?
1-7
Endomorphy
refers to relative fatness in physique
Mesomorphy
refers to relative development of the musculoskeletal system
Ectomorphy
refers to relative linearity of physique
For the three components what are the ratings?
0-12
Characteristics of Endomorphy
- large anterior-posterior diameter of body segments
- central concentration of mass
- abdomen predominates over thorax
- rounding of thighs and upper arms
- high square shoulders with soft contours
- neck appears short and thick
Characteristics of Mesomorphy
- body appears solid with the mass distributed uniformly
- muscles are large and defined
- upper arms and forearms are well muscled and evenly proportioned
- thoracic volume predominates over abdominal volume
- relatively slender wrists
- thighs and lower legs are heavily muscled and uniformly proportioned
Characteristics of Ectomorphy
- body has a high degree of linearity
- small anterior-posterior diameter
- shoulder droop (extreme cases)
- ribs are prominent
- shoulder are narrow and lacking muscularity
- both arms and legs tend to be relatively long relative to the trunk
- neck appears to be long and slender
- clavicles are usually prominent
What equipment is needed for an anthropometry?
- steel anthropometric tape measure
- calibrated beam balance weigh scale
- slim guide skinfold caliper or Harpenden skinfold caliper
- bone caliper - modified sliding steel caliper with vernier scale
- stadiometer
Step One of Procedure
- Measure all the anthropometric variables listed in table 3.1
Name the three Landmarks
acromiale, radiale, and ilionspinale
Acromiale
landmark on the shoulder which is a horizontal line marked on the skin level with the most superior and lateral point of the external border of the acromion process of the scapula
Radiale
landmark at the elbow which is a horizontal line marked on skin level with the proximal lateral border of the radius
Iliospinale
landmark at the point of hip which is a horizontal line marked on skin level with the undersurface of anterior superior iliac spine
Instrument to measure height
Harpenden stadiometer
Frankfort Plane
T = Tragion
O = Orbitale
V = Vertex
