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.
