Introduction
1.1 Body composition analysis through different anthropometric methods
The prevailing system of body composition is primarily focused on model, where the body is composed of two diverse compartments: fat mass (FM) and fat free mass (FFM). Indirect and direct anthropometric measurements can be used to assess nutritional status of particular individual and to determine body composition and distribution of body fat. Different methods have both adventages, as well as limitations. Furthermore, they might provide sources of measurement error. (Ulijaszek, 1999; Willet, 1998; Gibson, 2005)
1.2 Assessment of body composition
The anthropometric practices can measure the FM and FFM and therefore their amount and proportion can be used as determinants of nutritional status at both, the individual and population group levels. In regard, to the increased obesity epidemic and obesity related problems among children and adults in the United Kingdom, the importance of body composition assessment is crucial for short and long term health implications. It can define body fat distribution at individual level and therefore could classify those individuals with overnutrition. The latter, in Public Health significance, the assessment of body composition can help to recognize, in relatively early stage, individuals possibly exposed to both, under- and overnutrition and could influence health outcomes and regarded to overnutrition, prevent further expansion of obesity among population (Gibson, 2005; Reilly, 2003; Wells, 2008; Willet...

(Table 1 with comparison of the methods in Result section state for modifications) Moreover, some factors such as individual’s diet and physical activity, as well as stress factors and menstruation could affect changeability of creatinine excretion. The latter, purpose of longer urine collection period could effect on more precise results to predict individual’s muscle mass. Usually, in practice three sequential 24-hr urine collections should be used, however for the purpose of this study coursework only one day collection was assessed. (Gibson, 2005; Webster and Garrow, 1985)

Body Composition Essay

- Body composition is one of the five health related fitness components and it is the percent body fat, bone, water and muscle found in your body.

This ‘positive’ fat is known as essential fat, and the ‘negative’ fat is known as nonessential fat.

Sex Determination in Mammalian Embryos Essay

- Sex determination in mammalian embryos is the process by which an embryo is determined, at the cellular level, to become a male or female. At fertilization, a zygote will receive either an X or Y-chromosomes from the father’s sperm to accompany the X chromosomes given by the mothers egg. It is at this point that a zygote can be said to be male or female. However, the development of male or female sex organs is not determined until later in the sixth to seventh week of development. Genetics plays a significant role in sex determination, providing many gene loci that assist the process of cell determination and organ development....   [tags: Primary Sex Determination, Sex Chromosomes]

Colorimetric Determination for the Composition and Equilibrium Constant For the Formation of a Metal Complex Ion

- Colorimetric Determination for the Composition and Equilibrium Constant For the Formation of a Metal Complex Ion Abstract The object of this experiment was to determine properties for the formation of a metal complex ion, ferrothiocyanate by observing its colorimetric characteristics. The reaction was done for differing amounts of Fe+3 and SCN-, and the absorbance was measured using a spectrophotometer. The absorbance showed that maximum Fe(SCN)+2 ion production was achieved when the mole fraction of SCN was .6, which was close to the expected value of .5....   [tags: Experiment Analysis]

Essay about The Most Effective Method of Losing Body Composition

- The Most Effective Method of Losing Body Composition Body composition is the true definition of an individual’s weight status.

Reader Response Criticism to God's Determinations Essay

- Reader Response Criticism to God's Determinations For the reader demanding either rational sense or aesthetic pleasure from poetry, reading the preface to Edward Taylor's "God's Determinations" is humbling in ways unintended by the 17th century Puritan minister and poet. "Rationality" per se seems rejected at the start, where we are asked first to comprehend "Infinity," and then to envision it (everything) "beholding" "all things"(also everything). "Things" get no clearer as we progress, as we find whatever "infinity" "beholds" in not everything but "nothing," and that "nothing" itself to become the building material for "all." Identifying the paradox, perhaps, as that which begins t...   [tags: God's Determinations Essays]
