    Anthropometric Characteristics of Elite Rhythmic Gymnasts
    (2016) Arriaza, E.; Rodriguez, C.; Carrasco, C.; Mardones, C.; Niedmann, L.; López Fuenzalida, Antonio Eduardo
    The main aim of this study was to identify the morphological characteristics, to determine the tendency in the physical structure, differences and similarities according to categories based on age of the Chilean team of Rhythmic Gymnastics. We performed an anthropometric analysis of 60 gymnasts, fractioned by categories: preschoolers and schoolers (n = 11), junior (n = 28) and senior (n = 21). The anthropometric analysis was determined based on the study of the body composition, through pentacompartimental fractionation method (Kerr), somatotype (Heath & Carter) and the body mass index (Quetelet). The results showed significant differences between preschoolers and schoolers and higher categories (junior and senior) in the general anthropometric variables of body mass, height and BMI. Regarding the body composition, we only found significant differences in the percentage of muscle mass between the preschoolers and schoolers when being compared with the other two categories. In the study of somatotype, the prevalence of ectomorphic categorization was only found in the preschoolers and schoolers (meso-ectomorph), while in the junior category a mesomorph-ectomorph somatotype was observed and a central type in the senior category. We conclude that the morphology of the selected Chilean Rhythmic gymnastics depends on the category, as observed in the anthropometric characteristics related to the body composition and somatotype. Therefore, this factor is not useful in establishing a clearer tendency in the morph structure for this sport at a national level.

    M-protein gene-type distribution and hyaluronic acid capsule in group A Streptococcus clinical isolates in Chile: association of emm gene markers with csrR alleles
    (CAMBRIDGE UNIV PRESS, 2012) Wozniak, A.; Rojas, P.; Rodriguez, C.; Undabarrena, A.; Garate, C.; Riedel, I.; Roman, J. C.; Kalergis, A. M.; Garcia, P.
    Streptococcus pyogenes causes a variety of infections because of virulence factors such as capsular hyaluronic acid and M protein. The aim of this study was to determine emm types and capsule phenotype in 110 isolates of S. pyogenes from patients with invasive (sterile sites) and non-invasive (mainly pharyngitis) infections in Chile, and the relationship between both virulence factors. The most abundant types found were emm12, emm1, emm4 and emm28 and their distribution was similar to that seen in Latin America and developed countries, but very different from that in Asia and Pacific Island countries. Ten of 16 emm types identified in pharyngeal isolates were found in sterile-site isolates, and three of nine emm types of sterile-site isolates occurred in pharyngeal isolates; three emm subtypes were novel. The amount of hyaluronic acid was significantly higher in sterile-site isolates but did not differ substantially among emm types. Only three isolates were markedly capsulate and two of them had mutations in the csrR gene that codes for a repressor of capsule synthesis genes. We found a non-random association between emm types and csrR gene alleles suggesting that horizontal gene transfer is not freely occurring in the population.
