Measurement Reliability and Precision of Anthropometric Measures for the Estimation of Whole-Body Density in Professional Football Players: OAJBS Publishers

 Measurement Reliability and Precision of Anthropometric Measures for the Estimation of Whole-Body Density in Professional Football Players by Mills CD* in Open Access Journal of Biomedical Science (OAJBS)


Introduction: It is not uncommon to encounter measurement reliability issues, yet when they are required to develop practical calibration models to estimate whole body density the reliability of anthropometric measures is imperative.
Materials and Methods: Data was gathered from n=206 male professional footballers (±s; age = 24.1±5.4 years, body mass = 78.8±8.4 kg and stretched stature = 180.1±7.0 cm). Reliability of n=28 anthropometric variables (skinfolds, girths, breadths, depths, widths, residual lung volume, air displacement plethysmography and hydrostatic weighing) was investigated by applying Technical Error of Measurement (TEM%) and the Limits of Agreement (LoA) method.
Results: TEM% indicated a range of 6.5-1.0% and 3.8-0.6% and the study’s a priori criterion was set at ±3.8% for LoA and were statistically significant (P < 0.001). The contentious measurements of the iliac crest, supraspinale and anterior thigh skinfold, chest and hip girth and biiliocristal breadth indicated z scores values for R2 between 0.006-0.022% and exhibited significant bias (P=<0.05) and possible heteroscedasticity issues with highest r values of 0.611 and R2 (%) coefficients of 37.3%.
Discussion: Test-retest values demonstrated agreement and reliability to be of practical use with this population.

Facile Synthesis of Chitosan Nanoparticle with Different Features and Histopathological Ultrastructural Study on The Effect of Its Bio-complex with Bovine Serum Albumin in Mice Liver by Maged El-Kemary* in Open Access Journal of Biomedical Science (OAJBS)   We have synthesized chitosan nanoparticles (CS-NPs) with different characteristics using ionic gelation method. Results showed that the synthesized CS-NPs with different concentrations of trisodium polyphosphate (TPP) are irregular – spherical shaped with narrow size distribution and high stability. The microporous chitosan was also synthesized with new features characterized with different techniques as SEM, EDX, FTIR and BET. The synthesized microporous chitosan has a surface area and pore volume of 245.571m 2 /g and 0.155cm 3 /g respectively. Its microporous surface is functionalized with carboxyl and amine groups. Histopathological and ultrastructural studies of mice liver were performed using optical and scanning electron m...

Review on Analysis of Breast Tumor with Methods of Treatment: OAJBS Publishers

Review on Analysis of Breast Tumor with Methods of Treatment by Nagham Mahmood Aljamali* in Open Access Journal of Biomedical Science (OAJBS) Breast malignance is the greatest public in ladies, with a high incidence in North America and Eastern Europe, medium in Southern Europe and the Middle East and low in the Far East. Breast malignance is the second most common malignance in the world after lung malignance, and since it happens a lot, the doctors asked the women to examine themselves by themselves, in order to discover the signs of the disease early before it spreads. It is possible that this disease can be treated after being diagnosed by a specialized doctor and determining the type of tumor in the breast, and the surgeon removes the breast completely and starts chemotherapy about 6 doses, then radiotherapy, how many sessions will be determined by the doctor, and then hormonal therapy, a medicine called Tamoxafin or any medicine determined by the doctor, and it is possible. This ...
