“…In soccer, muscle damage is a very important physiological variable because all the high-intensity exercises produced in this sport (sprints, accelerations/decelerations, changes of directions and even tackles) may be associated with myofibril damage [ 42 ]. In this way, Machado et al carried out three studies on this specific topic: one with 20 healthy soccer players (age: 18.8 ± 1 years) [ 31 ]; another one with 15 male soccer players (age: 19 ± 1 years) [ 32 ] and the last one with 15 male soccer athletes (age: 18.4 ± 0.8 years) [ 30 ]. The main goal of these three investigations was to determine whether consumption of caffeine in single and acute doses (4.5–5.5 mg/kg) negatively affected blood markers typically used to assess the level of muscle damage.…”

Soccer is a complex team sport and success in this discipline depends on different factors such as physical fitness, player technique and team tactics, among others. In the last few years, several studies have described the impact of caffeine intake on soccer physical performance, but the results of these investigations have not been properly reviewed and summarized. The main objective of this review was to evaluate critically the effectiveness of a moderate dose of caffeine on soccer physical performance. A structured search was carried out following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines in the Medline/PubMed and Web of Science databases from January 2007 to November 2018. The search included studies with a cross-over and randomized experimental design in which the intake of caffeine (either from caffeinated drinks or pills) was compared to an identical placebo situation. There were no filters applied to the soccer players’ level, gender or age. This review included 17 articles that investigated the effects of caffeine on soccer-specific abilities (n = 12) or on muscle damage (n = 5). The review concluded that 5 investigations (100% of the number of investigations on this topic) had found ergogenic effects of caffeine on jump performance, 4 (100%) on repeated sprint ability and 2 (100%) on running distance during a simulated soccer game. However, only 1 investigation (25%) found as an effect of caffeine to increase serum markers of muscle damage, while no investigation reported an effect of caffeine to reduce perceived fatigue after soccer practice. In conclusion, a single and moderate dose of caffeine, ingested 5–60 min before a soccer practice, might produce valuable improvements in certain abilities related to enhanced soccer physical performance. However, caffeine does not seem to cause increased markers of muscle damage or changes in perceived exertion during soccer practice.

“…Essas características associadas com a intensidade em que o esporte está sendo praticado irão influenciar no grau de elevação e na duração em que esses marcadores permanecerão na corrente sanguínea. Neste sentido, diversos tipos de parâmetros bioquímicos têm sido utilizados, como marcadores bioquímicos de lesão celular; dentre eles, podem ser citadas as enzimas CK, LDH e AST (5,11,50,51) .…”

“…Dentre esses marcadores, podem ser citados os valores séricos de determinadas enzimas, tais como a creatine kinase (CK), a lactato desidrogenase (LDH) e a aspartato aminotransferase (AST). Estas enzimas são utilizadas como marcadoras de dano musculotendíneo pelo fato de serem citoplasmáticas e impermeáveis à membrana plasmática, apresentando aumento de seus valores séricos (1)(2)(3)(4)(5) . Níveis aumentados dessas moléculas no líquido extracelular podem indicar uma alteração da permeabilidade da membrana ou rompimento desta, sendo provocada pelo exercício físico (6)(7)(8)(9)(10)(11) .…”

Introdução: o kitesurfing é um esporte aquático em que o praticante utiliza a força do vento para deslizar-se com uma prancha sobre a água por meio de uma pipa controlável, estando o indivíduo sujeito a impactos, rápidas distensões e atividades excêntricas que podem causar danos musculoesqueléticos e oxidativos. Objetivo: revisar na literatura os mecanismos envolvidos na lesão em praticantes de kitesurfing e o papel desempenhado pela creatine kinase (CK) como marcadora de lesão esportiva. Materiais e métodos: trata-se de uma revisão narrativa onde foram incluídos trabalhos científicos publicados entre 1984 a 2011, a partir de buscas feitas nos idiomas inglês, português e alemão, das bases de dados do PubMed, Bireme, SciELO e Google Acadêmico com a combinação de palavras-chave. Foram encontrados 254 trabalhos e selecionados 72. Resultados: poucos trabalhos específicos sobre o kitesurfing foram encontrados, totalizando seis; destes, cinco estiveram preocupados em analisar a apenas a incidência das lesões e somente um os aspectos fisiológicos do esporte em referência. Neste sentido, nenhum trabalho esteve preocupado em analisar os mecanismos de geração de lesão e sua repercussão no nível tecidual e bioquímico. Conclusão: os níveis sanguíneos da CK, bem como seu comportamento ao longo do tempo, podem variar em função do tipo e da intensidade do exercício realizado. A quantidade de musculatura recrutada, a característica da contração muscular e a intensidade influenciarão na extensão e na gravidade da lesão. Neste sentido, o kitesurfing torna-se um interessante modelo para o estudo do comportamento das enzimas marcadoras de lesão muscular.

“…Além disto, há estudos apontando resultados positivos de alguns suplementos como, creatina, cafeína, proteína e carboidrato, em capacidades físicas importante para o futebol, podendo assim, atuar efetivamente como um recurso ergogênico potencializando o aumento da performance (MUJIKA et al, 2000;HESPEL;GREENHAFF, 2006;MACHADO et al, 2009;GILSON et al, 2010). Vale lembrar que a resposta fisiológica da utilização do suplemento pode variar de indivíduo para indivíduo, sendo assim, de extrema importância que a utilização dos suplementos seja "testada" em períodos de treino antes da competição.…”

The analysis of the variables of body composition, physical performance, bone structure and blood markers in different periods and situations on professional soccer players, is an important factor when we search the maintenance of the performance, in the perspective of sporting career of athletes over the years and in the prevention of injuries in this sport. The objectives of this study were: To compare the bone structure of professional´s soccer players of white and black race during the competitive period; and, describe and compare the hematological parameters of soccer players during the competitive period on function of the game positions and determine the anemia prevalence. Were participated of these analysis 38 professional soccer players in the age range from 19 to 33 years, belonging to a professional club of the first division of Brazilian soccer. Were analyzed the indicators of body composition, the indicator of physical performance, the indicators of quality and quantity bone and the hematological parameters. The physical performance was explored in the indicator of aerobic power (VO 2máx ), through the specific test of field: Yo-Yo Intermittent Recovery Test level 2. The variables that characterized the body composition were: fat mass (MG); stature (EST); percentage of body fat (%G), through measures of body mass, lengths and skin folds. The participants were subjected to qualitative ultrasound of no dominant hand phalanges to verify the bone quality and quantity (AD-SoS e UBPI). The hematological parameters were analyzed by intravenous blood test in fasting. The experience and the time of training were included in the amount of years of training experienced by the soccer players. The results indicate that the professional players of black race present a better bone structure in their phalanges in the no dominant hand in relation to those of white race. And there are no differences in hematological parameters of players of different tactical positions, as well as there are no prevalence of anemia in these professional soccer players.
