Blood concentration responses of c-reactive protein in college futsal athletes after an acute training session: a pilot study/RESPOSTAS DE CONCENTRACOES SANGUIENAS DA PROTEINA C REATIVA EM ATLETAS UNIVERSITARIOS DE FUTSAL APOS UMA SESSAO AGUDA DE TREINAMENTO: UM ESTUDO PILOTO

Futsal is an intermittent high-intensity sport that generates important biological disturbances, including possible changes in the secretion of inflammatory mediators, among these, Creactive protein ([CRP]). The objective of this study was to evaluate the responses of [CRP] in college futsal athletes who participated in an acute training session, as well as to verify a possible correlation between [CRP] and the ratio perception of effort (RPE) reported by athletes in this session. Blood samples were collected immediately pre-training, immediately post-training and 48 hours post-training. The results showed no significant change in [CRP] between the various collection times, as well as no correlation between [CRP] and athletes' RPE. The literature shows that the inflammatory responses of a training session, physical test, or even competitive matches vary depending on the type and loads of training, the competitive period and the level of conditioning of practitioners. It is concluded that a single Futsal training session, with exercises to improve strength, speed and technical and tactical aspects, does not constitute sufficient stimulus to alter [CRP] in college athletes during the 48 hours after the end of this session at the beginning of the competitive phase of training. Key words: Futsal. Inflammation. Immune system. Physical training. Physiology. O futsal e uma modalidade intermitente de alta intensidade, o que gera perturbacoes biologicas importantes, incluindo possiveis alteracoes na secrecao de mediadores inflamatorios, dentre esses, a proteina C reativa ([PCR]). O objetivo desse estudo foi avaliar as respostas das [PCR] em atletas universitarios de futsal que participaram de uma sessao aguda de treinamento, alem de verificar uma possivel correlacao entre as [PCR] e a percepcao subjetiva de esforco (PSE) informada pelos atletas nessa sessao. As coletas sanguineas ocorreram imediatamente pre-treinamento, imediatamente postreinamento e 48 horas pos-treinamento. Os resultados evidenciaram ausencia de alteracao significativa das [PCR] entre os diversos momentos de coleta, bem como ausencia de correlacao entre as [PCR] e a PSE dos atletas. A literatura mostra que as respostas inflamatorias de uma sessao de treinamento, de teste fisico, ou mesmo de partidas competitivas, variam em decorrencia do tipo e cargas de treinamento, do periodo competitivo e do nivel de condicionamento dos praticantes. Conclui-se que uma unica sessao de treinamento de Futsal, com
