anthropometric characteristics body composition and somatotype of elite male young runners
International Journal of Environmental Research and Public Health, 2020Co-Authors: Cristobal Sanchez Munoz, Jose Joaquin Muros, Oscar Lopez Belmonte, Mikel ZabalaAbstract:The purpose of the present study was to describe the anthropometric characteristics, body composition and somatotype of elite male young runners (EYR), and to compare these variables according to the specialty in which they engaged (middle-distance vs. long-distance). This will enable an anthropometric profile chart to be established for them. Ninety EYR aged 17 to 23 years (18.4 ± 2.0) participated in the study. Athletes were divided into two groups according to the event in which they participated: middle-distance runners (MDR, n = 56) and long-distance runners (LDR, n = 34). Sixteen anthropometric variables were recorded for each participant: Weight, height, eight skinfolds, four Girths, and two breadths. Body mass index (BMI), body composition and somatotype were calculated. Comparing MDR with the group of LDR, significant differences were found to exist for height, weight, relaxed upper arm Girth, flexed and tensed upper arm Girth, total upper arm area, upper arm muscle area, and thigh muscle area. No significant differences were observed in the other variables. MDR are taller, heavier and have larger Girths than LDR. Coaches and sports scientists can use the data obtained to better control training, as well as for talent identification and athlete selection.

world and olympic mountain bike champions anthropometry body composition and somatotype
Journal of Sports Medicine and Physical Fitness, 2018Co-Authors: Cristobal Sanchezmunoz, Jose Joaquin Muros, Mikel ZabalaAbstract:Background The aim of the study was to describe the anthropometric profile of male Olympic cross country (XCO) mountain bikers. Methods Fifty one XCO bikers participated in this study, divided into an elite group who competed in top level international competitions, and a non-elite group who competed at a national level. The elite group was further classified according to whether they had been world or Olympic champion mountain bikers (WOC) or not (NWOC). The anthropometric profiles included the measurements of height, weight, arm span, skinfolds, Girths, and breadths. Body Mass Index (BMI), body composition and somatotype were also calculated. Variables was described as mean, standard deviation and range. The standardizing of the variables was carried out using the Shapiro-Wilk with Lillieforts correction and homoscedasticity was analyzed using the Levene Test. After verifying that the variables were normal, the data were analyzed using non-paired t-tests (elite vs. non-elite and WOC vs. NWOC). Results Elite riders had significantly lower BMI, lower percentage of fat, total thigh area and larger thigh muscle area than the sub-elite riders, and presented significantly lower values for the endomorphic component and higher values for the ectomorphic component. The mean somatotype of the elite riders could be defined as ecto-mesomorphic (1.7-4.6-3.1). Conclusions Comparisons between of WOC riders and NWOC, showed that the WOC bikers had a significantly higher value for weight, arm span, upper arm Girth relaxed and upper arm Girth flexed and tensed, calf Girth, total upper arm area, and upper arm muscle area than the NWOC riders group.

parturient symphysio fundal height and abdominal Girth measurements to predict birth weight at muhimbili medical centre dar es salaam tanzania
Tanzania Medical Journal, 2007Co-Authors: N A Hamudu, Majid Shafiq, Karim P ManjiAbstract:Birth weight is known to influence morbidity and mortality. Simple measures to predict birth weight before delivery would therefore be useful in order to plan a delivery. Maternal parturient symphysio-fundal height has been used to detect Low Birth Weight. This study aims at predicting the fetal weight using the maternal symphysio-fundal height and abdominal Girth. A prospective study was done on 600 pregnant women admitted in labor. A detail anthropometric measurement was done and correlated with birth weight after delivery. Symphysio-fundal height and abdominal Girth measured to the nearest centimeter positively correlated with birth weight. The coefficient of correlation was 0.74 and 0.69 respectively with a significance of p 0.295). A formula was derived for the estimation of birth weight using these two parameters viz: Birth weight = Bo + B1 (Abdominal Girth) + B2 (symphysio-fundal height) where B0 is a constant =2.61, B1 (partial regression coefficient) = 0.32 (Standard deviation 0.002) and B2 (partial regression coefficient) = 0.081 (Standard deviation 0.004). The sensitivity in detecting birth weight below 2 kg was 88.2% and the specificity was 84.3%. While the specificity for detecting birth weight above 3.8kg was 83.3% and a specificity of 68%. The Symphysio-fundal height and abdominal Girth could predict the birth weight more closely than the gestational age.

abdominal obesity and coronary artery calcification in young adults the coronary artery risk development in young adults cardia study
The American Journal of Clinical Nutrition, 2007Co-Authors: Chong Do Lee, David R Jacobs, Pamela J Schreiner, Carlos Iribarren, Arlene L HankinsonAbstract:Background: Whether abdominal obesity is related to coronary artery calcification (CAC) is not known. Objective: We investigated the relations of waist Girth and waist-hip ratio (WHR) to CAC in 2951 African American and white young adults from the Coronary Artery Risk Development in Young Adults Study. Design: The present study was a cross-sectional and observational cohort study. Using standardized protocols, we measured CAC in 2001-2002 by using computed tomography and measured waist and hip Girths in 1985-1986 (baseline), 1995-1996 (year 10), and 2001-2002 (year 15, waist Girth only). CAC was classified as present or absent, whereas waist Girth and WHR were placed in sex-specific tertiles. Results: After adjustment for age, sex, race, clinical center, physical activity, cigarette smoking, education, and alcohol intake, baseline waist Girth and WHR were directly associated with a higher prevalence of CAC 15 y later (P for trend < 0.001 for both). The odds ratios (ORs) for CAC in the highest versus lowest tertiles of waist Girth and WHR were 1.9 (95% CI: 1.36, 2.65) and 1.7 (1.23, 2.41), respectively. Waist Girth and WHR at year 10 and waist Girth at year 15 similarly predicted CAC. These associations persisted after additional adjustment for systolic blood pressure, fasting insulin concentrations, diabetes, and antihypertensive medication use but became nonsignificant after additional adjustment for blood lipids. Conclusions: Abdominal obesity measured by waist Girth or WHR is associated with early atherosclerosis as measured by the presence of CAC in African American and white young adults. This is consistent with an involvement of visceral fat in the occurrence of coronary artery calcium in young adults.
