According to Hu and Nayak (2009) adipose tissue contains a mass density of 0.93g/mL and it is composed of 83% of total fat mass, of which 50% is found under the subcutaneous fat beneath the skin. The body reduces energy intake by burning fat reserves located inside the peritoneal cavity, packed in between internal organs and the torso (Goldhamer, 2010). The transportation of fat tissue around the body is intermittent, with diversity among essential fat and fatty layer. The total fat mass is reported to have 3% of fat mass, although it contains no protein. The fat free mass is consisting of all tissue without any involvement of fat. This is organised from tissue level which comprises non skeletal muscle, soft tissue, muscle tissue, bones including the component from the molecular and cellular level for instance glycogen, water and protein (Scott, 2008 and Park et al., 2011). To determine body composition various techniques is tested to obtain accurate density of body fat content. The test is conducted in a clinical or laboratory location and it is performed by trained technician. The common methods for identifying the level of adiposity includes body mass index (BMI), waist to hip ratio (WHR),waist circumference (WC), skinfolds, bioelectrical impedance analysis and the BOD POD (Esmat, 2012). The skinfolds measurements are routinely used to determine the results in the management of obesity. In addition it provides accurate and reliable body composition results from estimating the volume of subcutaneous fat and total body fat. It is very easy to use, non-invasive and cost less (McRae et al., 2010). The waist to hip ratio and the waist circumference is the ratio of the circumference of the waist and hips; it is used as indicator of fat distribution. Tanita Testing is another way of measuring BIA, it measure the whole body, it is less invasive and it involves less subject to human error/ BMI is a simple method used to assess how much an individual’s body weight and compare it from what is normal or desirable for a person of his or her height. The body mass indent= weight (kg)/ height2 (m) Garabed (2007). Bioelectrical impedance analysis is used to estimate body composition in particular body fat. BOD POD is a highly accurate method; it monitors obesity, risk factors for major diseases such as stroke and diabetes. Additionally, even though the method is very beneficial there are still error margins remaining. These error margins could be correlated with the increase in variability due to the diversity of the physical characteristics in a population or biological variations. A common method in indicating the error margin is done by calculating the technical error of measurements (TEM). The TEM provides accuracy index and demonstrates the measurement quality and control dimension. The index accede anthropometrists to verify the results when performing repeated measurements (intra-evaluator) or comparing with other results collected from other anthropometrists (inter-evaluator) Perini, 2005. The aim of this study is to compare the two methods and assess the error between the two. Methods: Subject1: UEL student, male (age=24; height=1.75; weight=69kg; BMI=22.5) the subject volunteered to participate in the study.
