Anthropometry

    The Student Handouts that relate to these Method activities are found in FSP25 Personal Dossier

    under the section Anthropometry Table. The students should work in groups of 3, all

    taking a turn at the 3 roles: What are anthropometric measurements?

    They are simply body dimensions. ; subject the person being measured The main thing about making anthropometric ; anthropometrist (measurer) the person

    doing the measuring measurements is that the students must be

    consistent. This means that if a student ; recorder the person writing down the measures Person X on Monday and then takes measurements

    the same measurements from Person X on When a student is the anthropometrist, they Tuesday (under the same conditions) they will should complete all of the measurements in get a very similar result. the order that is on the worksheet. When they

    have taken the measurement, they call out to They must also be accurate. This means that if the recorder, who then repeats what was said a student measures Person X on Monday, and and writes it down. another student also measures Person X on

    Monday, they would both get very similar For example, the anthropometrist says, results. “twenty two point zero centimetres”, and the

    recorder repeats, “twenty two point zero To do this the students MUST follow a centimetres” and writes it down on the procedure so everyone is taking the subject’s worksheet. measurements the same way. See below.

    After the anthropometrist has completed one Equipment round of all of the measurements, they repeat

    them all again from the beginning. Tape measure (the Lufkin tapes are the best as

    they have even pressure and don’t stretch). The recorders do NOT tell the anthropometrist

Average of the measurements

    Work out the average measurement by adding

    measure 1 and measure 2 and dividing by two.

    If you have taken three measurements, you DO

    NOT average the three measurements but add

    together the two closest measurements and

    divide by two.

    Eg: length lower arm

    measure 1 = 20 cm

    measure 2 = 19 cm

    measure 3 = 19.5 cm

    Add 19 + 19.5 and divide by 2.

    Average length = 19.25 cm

    Measurement Techniques

    In the Personal Dossier, students are asked to

    decide on a uniform and consistent method

    taking ALL of the measures.

    The techniques below are a guide as to what is

    acceptable.

    NB: These are NOT techniques as accredited

    by ISAK but are modified for this activity. The

    most important thing is that ALL students take

    the measurements the same way.

    Anthropometric measures Suggested Technique

    Standing height Feet together, heels, buttocks and upper part of back touching

    the wall. The head should not tilt upwards check that the A chart with accurately marked subject is looking straight ahead (chin slightly tucked in). intervals or a tape needs to be

    secured to the wall. The subject should breathe in (keep heels on ground).

    The measurer places a ruler at on the top of the head with

    firm pressure and holds the ruler in place as the subject slips

    out from their position. The measurer reads the score to the

    recorder.

    Arm span The subject stands with the back to the wall with the arms as

    horizontal as possible, palms facing forward, fingers fully It is useful to use a corner of the extended. Measure from tip to tip of the third fingers. room so only one mark needs to be

    made.

    Length lower arm The measurement should be taken from the upper edge of the

    elbow bone to the wrist bone on the thumb side of the hand. Elbow to wrist

    Length lower leg Subject should be seated, with their right ankle resting on

    their left knee. Measure from the fold of skin at the crease of Knee to ankle the upper leg and lower leg and the ankle bone.

    Length of foot This should be the distance from the longest toe to the most

    posterior point on the heel of the foot while the subject is Heel to longest toe standing with their weight evenly distributed.

    Circumference of head Tape should be just above the eyebrows, above the ears and

    pulled fairly tight to compress the hair.

Making the measurement charts

Height

    A piece of paper with 0.5 cm intervals marked can be taped to the wall.

    Rather than writing in all the intervals, determine the general range of heights within the class and complete a 30 to 40 cm wall chart.

     Arm span

    The arm span measurement will be similar to the height of the students. Create an interval chart and attach to the wall 1 meter from a corner.

    Students will stand with their fingertip of the third finger on the wall.
