Differences in physical performance between U-20 and senior top-level Brazilian futsal players.

BACKGROUND: The aim of this study was to compare performance in the Yo-Yo IR1, 20-meter sprint, COD test, loaded and unloaded lower-limb muscle power tests (squat jump [SJ], countermovement jump [CMJ] and jump squat [JS] tests), as well as resting and exercise heart rate variability parameters in high-level senior professional and under-20 (U-20) futsal players. METHODS: All the players (18 senior and 15 U-20 male players) performed the Yo-Yo Intermittent Recovery Test level 1 (Yo-Yo IR1), 20-m sprint, COD test, loaded and unloaded lower-limb power tests (SJ, CMJ and JS tests), as well as resting and post-exercise log-transformed root-mean-square difference of successive normal RR intervals (lnRMSSD) recording. The t-test for independent samples and magnitude-based inference were used to compare the groups. RESULTS: Seniors were likely to very likely superior than U-20 in the Yo-Yo IR1 (1506.7±287.1 and 1264.0±397.9 m, P<0.05), and resting (3.43±0.32 and 3.21±0.37 ms) and post-exercise lnRMSSD (2.95±0.39 and 2.48±0.59 ms, P<0.05). Conversely, U-20 players performed very likely to almost certainly better than seniors in the relative mean propulsive power (10.39±1.60 and 9.05±1.57 W/kg, P<0.05), 20-m sprint time (2.92±0.10 and 3.05±0.10 s, P<0.05) and COD (5.50±0.15 and 5.71±0.22 s, P<0.05). CONCLUSIONS: Findings from this cross-sectional study indicate that long-term exposure to futsal may lead to improvement in the aerobic fitness and cardiac autonomic regulation, while impairing the muscle power and speed performance of players. Future longitudinal studies are necessary to confirm the occurrence of such concurrent training adaptations.

Colonization of palm trees by Rhodnius neglectus and household and invasion in an urban area, Araçatuba, São Paulo State, Brazil.

The objective of this study is to report on the colonization of palm trees by Rhodnius neglectus, its invasion in an urban area, in Araçatuba - São Paulo, and the control and surveillance measures that have been put in place. Domiciliary triatomine searches occurred in apartments upon the inhabitants' notification. The collected insects were identified and examined for natural infection and food sources with a precipitin test. To search the palm trees, tarps were used to cover the floor, and a "Munck" truck equipped with a tree-pruning device was utilized. Chemical control was performed with the utilization of a manual compression. In 2009, 81 specimens of Rhodnius neglectus were collected from the domiciles by the population. The precipitin test revealed a presence of human blood in 2.7% of the samples. Entomological studies were carried out in these domiciles and in those located within a radius of 200 meters. The search performed in the palm trees resulted in the capture of 882 specimens of triatomines, negative for tripanosomatids. Mechanical and chemical controls were carried out. New searches conducted in the palm trees in the same year resulted in the capture of six specimens. The mechanical and chemical controls of the palm trees, together with the population's work, proved to be effective, therefore preventing these insects' colonization of the city's domiciles.

O objetivo deste trabalho é relatar a colonização de palmeiras por Rhodnius neglectus, sua invasão em área urbana, na cidade de Araçatuba - São Paulo, o controle e as medidas de vigilância instituídas. As pesquisas de triatomíneos nos domicílios ocorreram nos apartamentos quando da notificação pelo morador. Os insetos coletados foram identificados, examinados quanto à infecção natural e teste de precipitina. Na pesquisa das palmeiras foram utilizados lonas para forração do chão e caminhão Munck equipado com moto poda. O controle químico foi realizado com a utilização de compressor manual. No ano de 2009, foram coletados pela população 81 exemplares de Rhodnius neglectus em domicílios. O teste de precipitina acusou presença de sangue humano em 2,7% das amostras. Pesquisas entomológicas foram realizadas nestas edificações e naquelas situadas em um raio de 200 metros onde ocorreram as invasões. A pesquisa realizada nas palmeiras resultou na captura de 882 exemplares de triatomíneos, negativos para tripanosomatídeos. Foi realizado controle mecânico e químico. Novas pesquisas realizadas nas palmeiras avaliadas no mesmo ano resultaram na coleta de seis exemplares. Os controles mecânicos e químicos das palmeiras aliado ao trabalho de participação popular mostraram-se factíveis impedindo a colonização destes insetos nos domicílios da cidade.
