Esta t?cnica ? muito aceita por profissionais da sa?de e atletas, por?m os estudos ainda s?o controversos em rela??o aos benef?cios fisiol?gicos Objetivo: Avaliar o efeito acumulativo de CWI no processo de recupera??o muscular de atletas de futebol. Materiais e M?todos: Trata-se de um ensaio cl?nico randomizado. Foram inclu?dos 23 atletas aleatoriamente divididos em dois grupos: controle (10 minutos sentados) e experimental (CWI 10?C ?10 minutos). Ao todo, foram realizadas 7 sess?es imediatamente ap?s o treino. Foram avaliados, Creatina Quinase (CK), Lactato Desidrogenase (LDH), Atividade Eletromiogr?fica (pico do reto anterior, vasto lateral, b?ceps femoral), For?a Isom?trica de flexores e extensores de joelho, Pot?ncia do Salto, Percep??o Subjetiva de Esfor?o (PSE) e Percep??o de Recupera??o (PR). As avalia??es funcionais ocorreram no primeiro dia (pr? e p?s treino) e repetidas no ?ltimo dia. Al?m destes momentos, CK e LDH foram mensuradas com 24 horas ap?s o esfor?o. PSE e SR foram coletadas todos os dias. A an?lise estat?stica utilizada foi a Anova Mista, com Post-Hoc de Bonferroni, considerando o n?vel de signific?ncia de 5%. Resultados: Observou-se intera??o significativa nos n?veis de CK (p=0,02), tempo (p=0,005) e para grupos nos dias 9 e 10 (p= 0,01). Para LDH houve diferen?a intragrupos (p=0,03) e intergrupos no dia 10 (p=0,03). N?o obtiveram diferen?as para as an?lises de desempenho neuromuscular nem para a PSE. Para a SR houveram diferen?as intragrupos (p=0,001) e intergrupos (P=0,033) para o quinto e sexto dia. Conclus?o: O uso acumulativo da crioterapia por imers?o atenua o dano muscular, n?o inibe o processo de adapta??o para melhora do desempenho e promove sensa??o de recupera??o. / Football is a sport with congested calendars, which requires recovery strategies such as cold water immersion (CWI). This recovery technique is well spread through football clubs, although it lacks a profound physiologic investigation to understand its effects on athlete?s body. Objectives: The main objective of this study is to evaluate the effect of a long-term CWI exposure in football athlete?s. Methodology: In order to answer this question, we performed a randomized clinical trial in 23 sub-20 football athletes. All subjects were randomly divided into two groups; a control group (10 minutes seated rest) and a CWI group (10 minutes in a 10?C) during seven days in a row. We evaluated creatine kinase (CK) and lactate dehydrogenase (LDH) as molecular biomarkers for muscle damage. The blood samples were collected on the first, second, ninth and tenth days. Yet, we assessed the peak of muscle activity and isometric strength of the knee flexors and extensors, potency of lower limbs, perceived exertion (PE) and total quality recovery perceived (TQRPer) in order to understand the treatment physiological effect on the subjects on the first and last day of experiments (before and after training). Results: We found that CK is lower in the CWI group compared to control on the days 9 and 10 but not on the first applications. The LDH levels were different between groups only on the last evaluation on the tenth day. We did not find any changes in the neuromuscular performance or on the PE evaluation. Although, we found differences in the TQRPer evaluation comparing CWI and control groups on the fifth and sixth days. Conclusion: The long-term CWI exposure attenuates muscles damage, increase the perceived recovery and doesn?t inhibit the process of adaptation necessary for the performance improvement.

Foram utilizados ?leos de Abacate (AB), C?rtamo (CA), Coco (CO), Linha?a (LI) e Pequi (PE), e Banha de Porco (BAN), Margarina (MAR), Manteiga (MAN) e Gordura Vegetal Hidrogenada (GVH). Os ?leos AB, CO, CA e LI tiveram maiores quantidades de fen?licos totais do que as gorduras BAN GVH, MAN e MAR. O CO apresentou maior quantidade de flavon?ides do que os ?leos LI, CA, AB e PE. A GVH apresentou maior quantidade de flavon?ides seguida da MAR, MAN e BAN. Os espectros de infravermelho mostraram a presen?a do grupo hidroxila na posi??o de estiramento 3650-3100nm, o que caracteriza a a??o AA nos ?leos e gorduras. Os cromatogramas identificaram as principais subst?ncias vol?teis dos ?cidos graxos como os ?cidos Capr?lico, L?urico, Miristico, Palm?tico, Este?rico, Ol?ico, Linol?ico, Eicosapentaen?ico e o Ela?dico. No ensaio biol?gico os animais receberam ra??o acrescida de 10% de cada ?leo e gordura, e o grupo controle recebeu apenas a ra??o. Na suplementa??o dos animais o coeficiente de ingest?o alimentar dos grupos AB, BAN,CA, LI, MAN e PE foram os maiores. Os grupos BAN, MAN, MAR e GVH apresentaram maior IMC que o grupo C, que por sua vez apresentou menor ?ndice que os grupos AB, CA, CO, LI e PE. Para o ?ndice de LEE os grupos AB, CA, CO, LI e PE tiveram maior ?ndice que GVH, MAN, MAR, BAN e C. O grupo MAN apresentou maior teor de glicose. Quanto a fra??o de triacilglicer?is e HDL-c os grupo BAN, GVH e MAN foram maiores em rela??o aos demais. Contudo pode se concluir que mesmo os ?leos e gorduras apresentando atividade antioxidante e presen?a de fen?licos e flavon?ides tendo efeitos ben?ficos para a sa?de, o consumo excessivo dos mesmos causa aumento do metabolismo lip?dico. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Qu?mica, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2015. / ABSTRACT Given the interest and influence of ingested fats and oils in food, its effects on metabolism and changes in body composition, this study aimed to characterize chemically oils and fats by GC-MS, FTIR spectrometry (phenolics, flavonoids and Antioxidade Activity), and to evaluate the effect of supplementation in experimental animals. Were used oils Avocado (AB), Safflower (CA), Coconut (CO), Flaxseed (LI) and Pequi (PE), and Lard (BAN), Margarine (MAR), Butter (MAN) and Hydrogenated Vegetable Fat (GVH). The AB, CO, CA and LI had higher amounts of total phenolics than the BAN GVH fats, MAN and MAR. The CO had higher amounts of flavonoids than the LI oils, CA, AB and PE. The GVH had higher amounts of flavonoids then the SEA, MAN and BAN. Infrared spectra showed the presence of the hydroxyl group in position 3650-3100nm stretch, which characterizes the EA action in oils and fats. The chromatograms identified the major volatile substances of fatty acids such as caprylic, lauric, myristic, palmitic, stearic, oleic, linoleic, elaidic and Eicosapentaenoic. In the biological test animals received diet plus 10% of each oil and fat, and the control group received only the diet. In supplementation of animals the intake of food coefficient of AB groups, BAN, CA, LI, MAN and PE were the greatest. The BAN groups, MAN, SEA and GVH had higher BMI than group C, which in turn showed a lower rate than the groups AB, CA, CO, LI and PE. For LEE index AB groups, CA, CO, LI and PE had higher rate than GVH, MAN, MAR, BAN and C. The MAN group had higher glucose content. As the fraction of triacylglycerol and HDL-c the BAN group, GVH and MAN was higher than the other. However it can be concluded that even the oils and fats presenting antioxidade activity and presence of phenolics and flavonoids with beneficial health effects, excessive consumption of these causes increased lipid metabolism.
