Length and height change through longitudinal growth. Standards have been developed for international cohorts, ethnicity specific cohorts and for many syndromic conditions. Keywords: length by age , length by gender , international standards , height velocity , height prediction
1 wrz 2013 · Leg length contributes significantly to height. Its relationship to height is reflected in the upper-to-lower segment ratio. Arm span can be measured and compared to height. Measurements of the proximal, middle and distal limb segment can be used to distinguish growth abnormalities affecting the respective segments.
Calf, thigh and upper arm circumferences are also used to estimate changes in musculature/lean mass and are strongly influenced by variation in appendicular skeletal muscle. Waist and hip circumferences are measures of "abdominal girth", the circumference around the midriff of the body.
Size and Shape in Biology: Elastic criteria impose limits on biological proportions, and consequently on metabolic rates. Arguments based on elastic stability and flexure, as opposed to the more conventional ones based on yield strength, require that living organisms adopt forms whereby lengths increase as the ⅔ power of diameter.
Calf Circumference. Calf circumference also provides information about normal muscle mass. It can reflect a decrease in muscle mass with limited physical activity. A result of more than 31 cm is considered normal (Tsai et al., 2008).
Circumference, also known as girth, is commonly measured in forestry, but usually it is then used to estimate bole diameter. If the bole were circular, diameter can be estimated as circumference divided by π. However, if the bole deviates from this ideal shape, then this calculation will overestimate the diameter.
