Anthropometric Assessment Systems BPK 303

Anthropometric Assessments  Comparison of Anthropometric measures to normative data.  Measures intended to reflect growth and/or body composition.  Reliable measurement of standardized techniques essential.  Appropriate norms?

C.F.S. - Canada Fitness Survey 1981 Canadian Fitness and Lifestyle Research Institute Canadian Fitness and Lifestyle Research Institute  The 1981 Canada Fitness Survey was the first nationally representative study of the physical recreation habits, physical fitness, and health status of an entire population.  More than 23,000 Canadians aged 7 and older participated in this historic survey, providing baseline data representing all Canadians except the 3% not living in households.  The anthropometric and performance data was then used as the normative data for the Canadian Standardized Test of Fitness

C.S.T.F.  Canadian Standardized Test of Fitness  Performance Tests  Step test, grip strength, push ups, sit ups, sit and reach.  Anthropometric Assessment consisted of:  % body Fat determined by the Durnin & Womersley equations based upon the sum of 4 skinfolds (Triceps, Subscapular, Biceps, and Iliac Crest)

Durnin & Womersley (1974) Density = a (log 10 Sum 4 SF) + c ◦ Sum of Triceps, Subscapular, Biceps, and Iliac Crest Skinfolds ◦ a & c dependent upon age and gender specific equations ◦ British sample measured on the left side of the body % Fat = (4.95/Density)-4.5) x 100 Problems encountered by C.S.T.F. ◦ Overpredicts by 3 - 5% Fat ◦ Upper body sites

C.S.T.F.  Canadian Standardized Test of Fitness  Revised Anthropometric Assessment included:  Body Mass Index  Sum 5 Skinfolds  Sum Trunk Skinfolds  Waist to hip girth ratio

C.P.A.F.L.A. The Canadian Physical Activity, Fitness & Lifestyle Approach Modification of the C.S.T.F. ◦ Change in style – Rather than using Health Risk Zones, Health Benefit Zones were identified Anthropometric Assessment includes: ◦ Body Mass Index (BMI) ◦ Sum of Five Skinfolds (mm) (SO5S) ◦ Waist Girth (cm) (WG) ◦ Sum of Two Trunk Skinfolds (mm) (SO2S) C.P.A.F.L.A. was taught in BPK 343 now it is C.S.E.P.

Advanced O-SCALE System for individual physique assessment

Developed to fill a need  % body fat predictions have unacceptably high S.E.E.’s  Individual assessments vs group validation  Designed with the expectation of becoming obsolete very soon

Components  Anthropometric measures  Height, Weight, Skinfolds, Girths, Humerus and Femur width  Geometric scaling  Maintain shape and composition  General appraisal of physique  A and W ratings  Detailed appraisal  Size and Proportionality Profiles

 STANINE chosen for O-SCALE system based upon number of categories and equal width of categories Stanine Category Percentage of Normal Distribution within Category 4%7%12%17%20%17%12%7%4% Boundary Z-Scores Boundary Percentiles

General description of physique  Adiposity rating based on skinfolds  Proportional weight rating  Stanine scores  equal width of categories  nine categories seemed appropriate

Adiposity Rating  Proportional Sum of six skinfolds  Sum 6 SF * (170.18/Ht)  Comparison to age and sex specific norms via stanine scale

Females 23 year old female Prop. Sum of 6 skinfolds = 79.4 Adiposity (A) rating = 3

Proportional Weight Rating  Proportional Weight  WT * (170.18/HT) 3  Comparison to age and sex specific norms via stanine scale

Females

A & W Ratings  A = 7, W = 7, - Balanced physique  A = 7, W = 5, - Adiposity dominant  A = 5, W = 7, - Weight dominant

Detailed Description of Physique  Listing of all measures with 4th, 50th & 96th percentiles  Proportionality profiles  z-values plotted vs similarly scaled norm values
