Study Questions #5
3. In the O-scale system of body composition assessment, what is the rationale for using
a height adjustment when calculating the Adiposity rating and the Proportional weight
rating?
So the numbers produced are more comparable. It makes sense to adjust for height because a
person that is short but fat may have the same weight as someone who is tall and normal
weight. These people should not be put in the same category. Comparisons of proportions b/w
individuals can be made.
4. In the O-scale system of body composition assessment, how is the adiposity rating
used to help interpret the Proportional weight rating?
Those with low adiposity ratings, yet high proportional weight ratings are shown to be
overweight rather than over-fat, this becomes helpful with very athletic people such as
bodybuilders
5. What advantages do the O-scale system and the canadian physical activity, fitness and
lifestyle appraisal- health body composition assessment procedure have in comparison
to percentage body fat predictions from skinfold measurements, when used in individual
assessments?
The O-scale and Canadian physical activity, fitness and lifestyle appraisal are better at targeting
where the additional fat is, rather than just if the subject is overweight or not.
6. With referencing to the O-scale system of body composition assessment, describe the
following terms:
Stanine scale: arbitrary scale in comparisons to the normal distribution
Adiposity rating: fat tissue rating
Proportional weight rating: fat to weight proportionality
Balanced physique: having equal adiposity and proportional weight rating
Dominant physique: non-equal adiposity and proportional weight ratings; higher

2. In the CSEP Physical Activity, Fitness and Lifestyle Assessment - Body Composition
procedure, why are different norm tables used for clients under 20 years of age versus
clients over 20 years of age?
BMI changes substantially as children grow and get older, and because adiposity varies with
age and gender during childhood and adolescence.
Document Summary
It makes sense to adjust for height because a person that is short but fat may have the same weight as someone who is tall and normal weight. These people should not be put in the same category. Stanine scale: arbitrary scale in comparisons to the normal distribution. Balanced physique: having equal adiposity and proportional weight rating. Dominant physique: non-equal adiposity and proportional weight ratings; higher. It provides insight to increased risk of obesity-related illness due to location of excess fat. Paralyses of the deltoid muscle would affect the joint movements in the shoulder girdle. The person would be unable to perform flexion, horizontal extension and flexion, and abduction. This would make activities using the upper portion of the arms nearly impossible. The tendons of the hamstrings cross the knee joint they flex the knee joint. The quadriceps would be affected as well since they are also.
