Análisis del perfil antropométrico de jugadores de la selección Brasileña de voleibol infanto juvenil

El voleibol brasileno es reconocido por su excelencia en el ambito internacional. Las victorias en las categorias de base permiten que jovenes jugadores talentosos lleguen a las selecciones nacionales. Una herramienta importante en el proceso de seleccion de jovenes atletas es la antropometria que evalua la forma y tamano de los jugadores. Esta investigacion verifico las caracteristicas antropometricas de los jugadores de la seleccion infanto juvenil de Brasil. Se evaluaron 16 jugadores con edad de 16,8 0,58 anos del sexo masculino convocados para el Campeonato Sudamericano de 2006, utilizando el protocolo de Lohman para verificar la percentaje de grasa y el Somatotipo de Heath & Carter de acuerdo con la posicion dentro del campo de juego: colocador (COL) (n=3), libero (LIB) (n=2), central (CEN) (n=4), punta-receptor (PR) (n=4) y Opuesto (OP) (n=3). Fue utilizada la estadistica descriptiva para la caracterizacion antropometrica y la ANOVA con post hoc de Tukey para observacion de las diferencias entre las posiciones de los jugadores. Fueron observadas diferencias significativas en la masa corporal y estatura entre LIB y CEN, y entre LIB y OP. Sin embargo, no fueron observadas diferencias entre las posiciones de juego en porcentaje de grasa y componentes de lo somatotipo. Esto apunta para una seleccion de atletas que busca jugadores altos y lineales independiente de la funcion de campo. La unica posicion que presento diferencias fue el LIB.

Efeitos de um programa de reabilitação pulmonar sobre mecânica respiratória e qualidade de vida de mulheres obesas

INTRODUCTION: Obesity is a metabolic disease that is characterized by a multifactorial etiology, which induces fat accumulation, oftentimes leading to morbid conditions or even death. OBJECTIVE: The present study aims to verify the effects of a pulmonary rehabilitation program over respiratory mechanics, functional capacity, and life quality of 20 sedentary obese women aging in average 48.75 ± 13.71 e IMC de 34.54 ± 3.85 kg/m2. MATERIALS AND METHODS: The volunteers were submitted to an interview using the SF-36 questionnaire as a tool in order to determine the quality of life, take body mass measures, as well as stature, thoracic-abdominal cytometry, minute and volume tidal, slow vital capacity, and maximum and minimum inspiratory pressure. The comparison of results before and after the implementation of the pulmonary rehabilitation Program were tested by a paired Students t-test, having been noted a p < 0.05 value. RESULTS: The results after the program were statistically significant (p < 0.05) for minute volume of 11008.30 ± 5035.53 mL (p = 0.001), volume tidal of 758.70 ± 345.78 mL (p = 0.023), slow vital capacity with 632.95 ± 852.25 mL (p = 0.001), maximum inspiratory pressures with -69.75 ± 21.37 cmH2O (p = 0.045) and maximum expiratory pressure with 74.50 ± 28.23 cmH2O (p = 0.000), and in the perception of life quality concerning the general health condition 76.5 ± 14.04 (p = 0.033), social aspects 83.1 ± 18.71 (p = 0.031), emotional aspects 88.4 ± 19.52 (p = 0.042), and in mental health 83.4 ± 14.81 (p = 0.049). CONCLUSION: The pulmonary rehabilitation program here proposed managed to promote positive effects, improving respiratory mechanics and life quality of sedentary obese women.

Digital dermatoglyphic heritability differences as evidenced by a female twin study.

The genetic and environmental contributions to determine digital dermatoglyphic traits were investigated by using female dizygotic and monozygotic twin pairs to estimate heritability indexes (h(2)). The evaluated sample was composed by 20 monozygotic twin pairs and 13 dizygotic twin pairs. A significant heritability (h(2) = 0.65 to 0.96) was observed for 12 dermatoglyphic characteristics (delta indexes and ridge counts for right hand, left hand and both hands, and ridge counts for most individual fingers). A negative correlation between the ridge counts and heritability indexes from individual fingers was found for the left hand, which appears to be associated to a higher arch pattern frequency in most left-hand fingers, since this frequency was negatively correlated with ridge counts and positively correlated with heritability indexes. Heritability indexes of right-hand fingers were positively correlated with loop pattern frequency and negatively correlated with whorl pattern frequency. The low heritability of ridge counts from left thumb, ring and little fingers (h(2) = 0.11 to 0.32) indicates a higher chance that the chorion type had an influence in the intra-pair variance of monozygotic twins. Results confirmed the predominant genetic influence on the total ridge count. The heritability indexes varied in up to 8 times between different fingers and its association to ridge counts and pattern frequency was very variable between hands, evidencing that the use of dermatoglyphic traits from individual fingers as indicators of genetic influences to other human traits should consider this variability.

MOTOR FEATURES, DERMATOGLYPHIC AND EEG PERIODS OF GIRLS IN PRE AND POST MENARCHE

The identification of menarche at puberty is important to evaluate the physical qualities, since the organism is developing a result of maturation. The dermatoglyphic characteristics are presented as possible indicators of genetic predispositions for basic physical qualities such as strength, speed, endurance, power and coordination. The aim of this study is relation of motor characteristics, dermatoglyphic and brain electro in girls in the periods before and after menarche. For this purpose the sample consisted of 45 girls aged between 10 and 14 years and 11 months divided into two groups, 21 in pre-menarche group (G1) and 24 in post menarche (G2). The variables analyzed were: motor characteristics, dermatoglyphic and EEG (absolute power in alpha and beta) electrodes in the frontal regions (F), central (C) and parietal (P), using the protocol KTK, protocol and capture fingerprints spectral activity through EEG. The results show a significant difference in QM4 for a p≤.05 between groups G1 and G2, and the G2 achieved better performance. Compared the results of the motor characteristics, dermatoglyphic and electroencephalographic they indicate significant differences in spectral activity of the alpha rhythm in girls belonging to the group after menarche. It was observed that, with respect to motor characteristics, dermatoglyphic and EEG, the groups are not presented separately. However, to join the motor characteristics, dermatoglyphic and EEG groups before and after menarche, there was a significant difference with respect to brain activity only in the alpha rhythm and at frontal (F3, FZ, F4) and central (C3 and CZ) and in the post menarche.

Association between Dermatoglyphic Configuration and the ACTN3 Genotype in Juvenile Male Athletes / Odnos između dermatoglifske konfiguracije i ACTN3 genotipa u maloljetnih muških atletičara

This study examined whether dermatoglyphic characteristics are associated with the α-actinin isoform 3 (ACTN3) R577X sequence variant, employing descriptive and comparative approaches. Boys (N=82) were classified according to the dermatoglyphic configuration of their digital impressions into the following groups: Anaerobic Power (AP=8); Speed Resistance (SR=44); Pure Force (PF=5), and Aerobic Resistance (AR=25). All of the AP group subjects (9.76% of the subjects) had a genetic predisposition for anaerobic power performance, with 37.5% being RR homozygotes and 62.5% being RX heterozygotes. The dermatoglyphic profiles, correlated with the ALW fingerprint formulas, classified the SR group (53.66% of the subjects) as having speed resistance. The PF group (6.09% of the subjects) notably all had AL fingerprints and an absence of W. Finally, the AR group (30.49% of the subjects) had a predisposition for aerobic capacity. In conclusion, dermatoglyphic features can be associated with the R577X allelic variant of the ACTN3 gene, as much through anaerobic muscle power profiling as through the ACTN3 genotype.
