The sample consisted of 36 female subjects (age: 30.2 +4.7 years;
height: 163.6 +5.4cm; weight: 64.5 +7.2Ka). The leg circumferences C: of
both legs marked with dermographic pencil and shown in Fig. 1 were initially
measured directly with a tape in a direction perpendicular to the bone axis.
The nearly-vertical distances H, Of successive profiles were measured on the
outer side of the legs following the slope of their surface. Repeated
readings resulted in estimated measuring errors of +0.25cm for Ci and +0.04cm
for E These directly determined values were nonetheless regarded as the
"true" values.
The leg portion of interest was thus partitioned into five segments.
Following Jones and Pearson (1969) and Katch änd Katch (1974) who have both
used a similar anthropometric technique, these were regarded as truncated
cones with base circumferences C; and heights h,. The latter, being vertical,
are not equal with Hs and were obtained after correcting the H's for eleva-
tion differences using depth data taken from the moiré photograhs. Total
surface area A and volume V (using H, and JT respectively) were finally
computed by means of the truncated cone formulae.
Four photographs, i.e. left and right side-view (s.v), front-view (f.v.)
and back-view, were taken of each subject. For f.v. photographs the subject
stood erect with feet slightly but a standard distance apart and hands cros-
sed behind the back. For s.v. photographs the subject was posed so that only
the leg closer to the lens would appear on the image, clearly outlined
against the board, and the arms were stretched horizontally. A back-view
photograph was also taken for documentation purposes. Apart from the above
and frompositioning the body as close as possible to the grating (a step di-
ctated by moiré depth of field limitations) no special posing procedure was
followed, and random posing effects are thus included in the final results.
All measurements were made on contact prints with a precision glass ruler.
Height Measurements
Height hi determination was based on measurements of successive girth
mark distances on the outer side of the leg made on s.v. photographs along
their vertical (y) axis. These were transformed into vertical life-size
heights hs using the mean scale provided by moiré fringes. The Hi's were
obtained from the his and the depth differences AZ. For each subject the
mean of h, (left) and h, (right) and the mean of H; (left) and Hi (right)
were used.
