Abstract: RESUMO: A pesquisa em questão assume como objeto de estudo as memórias de um sensei pioneiro no Judô de Maringá e de cinco judocas kohais pioneiros na cidade. O enfoque dado às memórias se deu no processo de implementação e consolidação do Judô maringaense. As recordações foram coletadas com base na metodologia da História Oral, que apresenta diretrizes para o registro de memórias de sujeitos, proporciona uma (re)leitura de acontecimentos do passado e possibilita a construção de narrativas compartilhadas. As lembranças dos entrevistados são resquícios históricos que resistiram ao tempo e, contemporaneamente, apresentam-se como dados que necessitam ser contextualizados para elucidar os fenômenos de implementação e consolidação de uma prática sociocorporal em Maringá. Assim, os relatos dos interlocutores selecionados foram assumidos como o eixo articulador entre o passado e o tempo presente. O recorte temporal proposto situou-se entre as décadas de 1960 e 1970, período de surgimento e efetivação dessa luta no município. Investigar o Judô em Maringá por meio de narrativas orais é destacar a importância da preservação da memória de sujeitos que vivenciaram a implementação e a consolidação de uma prática corporal relevante à cidade. O processo analisado no presente estudo possui múltiplas dimensões, sendo uma delas a percepção de personagens históricos sobre o passado para a construção de narrativas escritas da modalidade. Partindo dessas ideias, essa pesquisa orienta-se pelo seguinte problema: como se deu a implementação do Judô em Maringá e como ocorreu a consolidação dessa luta na cidade? Assumindo como norteadora essa pergunta, a temática investigada possui como objetivo geral: analisar as narrativas orais de pioneiros do judô em Maringá no sentido de entender como essa memória contribui para a compreensão do processo de implementação e consolidação da modalidade, nas décadas de 1960 a 1970. De forma específica, buscou-se compreender historicamente os fatos e fenômenos memorados por interlocutores do Judô maringaense, com base na metodologia da História Oral; associar e contextualizar historicamente as memórias dos entrevistados, referentes ao processo de implementação e consolidação da modalidade em Maringá; e constatar os principais fenômenos que permearam o processo de implementação e consolidação do Judô na cidade, a partir de suas narrativas orais. Os dados da pesquisa revelam que os clubes sociais e associações culturais foram imprescindíveis para a implantação do Judô em Maringá, haja vista ser essa luta caracterizada como um elemento de integração entre culturas que se instalam localmente, permeado por um fenômeno nacional de hibridização cultural entre nipônicos e brasileiros. Constata-se, ainda, a influência do fenômeno de padronização de regras e técnicas, a ausência da participação de judocas femininas na implantação do Judô maringaense e a estruturação dos treinamentos com base em uma concepção tradicionalista japonesa de treino. Conclui-se que o Judô, em Maringá, origina-se e desenvolve-se como forma do empenho dos senseis em racionalizar essa prática corporal tradicional no contexto da cidade, o que coincide com a intensificação da esportivização dessa luta no mundo e com a expansão comercial do terceiro setor na cidade; ABSTRACT: The research in question assumes as object of study the memories of a sensei pioneer in Judo of Maringá and five kohais judoka pioneers in the city. The focus given to the memories occurred in the process of implementation and consolidation of the Jonah Maringa. The recollections were collected based on Oral History methodology, which provides guidelines for the recording of subject memories, provides a (re) reading of past events and enables the construction of shared narratives. The memories of the interviewees are historical remnants that have stood the test of time and, at the same time, present themselves as data that need to be contextualized to elucidate the phenomena of implementation and consolidation of a sociocorporal practice in Maringá. Thus, the reports of the selected interlocutors were assumed as the articulating axis between the past and present time. The proposed temporal cut was between the 1960s and 1970s, the period of emergence and effectiveness of this struggle in the municipality. Investigating Judo in Maringá through oral narratives is to highlight the importance of preserving the memory of subjects who have experienced the implementation and consolidation of a body practice relevant to the city. The process analyzed in the present study has multiple dimensions, one of them being the perception of historical characters about the past for the construction of written narratives of the modality. Based on these ideas, this research is guided by the following problem: how did the implementation of Judo in Maringá took place and how did the consolidation of this struggle take place in the city? Assuming as a guideline this question, the subject investigated has as general objective: to analyze the oral narratives of judo pioneers in Maringá in order to understand how this memory contributes to the understanding of the process of implementation and consolidation of the modality, in the decades of 1960s to 1970s. Specifically, we sought to understand historically the facts and phenomena memorized by interlocutors of the Maringá judo, based on Oral History methodology; to associate and contextualize historically the memories of the interviewees, referring to the process of implementation and consolidation of the modality in Maringá; and to verify the main phenomena that permeated the process of implementation and consolidation of Judo in the city, based on their oral narratives. The research data reveal that social clubs and cultural associations were essential for the implementation of Judo in Maringá, given that this struggle is characterized as an element of integration between locally installed cultures, permeated by a national phenomenon of cultural hybridization between Japanese and Brazilians. The influence of the phenomenon of standardization of rules and techniques, the absence of the participation of female judokas in the implantation of the Maringa Judo, and the structuring of the training based on a traditionalist conception of Japanese training. It is concluded that Judo, in Maringá, originates and develops as a form of the commitment of the senseis to rationalize this traditional corporal practice in the context of the city, which coincides with the intensification of the sportivization of this struggle in the world and with the expansion of the third sector in the city

Abstract: Resumo: A presente pesquisa teve como objetivo avaliar os efeitos protetores de um programa de treinamento físico moderado ou aeróbio realizado em diferentes fases do desenvolvimento sobre o crescimento do tumor de Walker-256, e se existe interferência da insulina sobre o crescimento tumoral no modelo animal proposto. Também pretendeu demonstrar alterações biométricas, fisiológicas e metabólicas que pudessem surgir em decorrência do protocolo de corrida em esteira utilizado e da inoculação tumoral subsequente. Para tanto, foram avaliados consumo máximo de oxigênio (VO2máx), velocidade máxima de corrida, evolução ponderal, consumo alimentar, estoques de gordura, níveis plasmáticos de glicose, insulina, triacilgliceróis (TAGs), colesterol total e HDL. Além disso, foram realizados experimentos in vivo e in vitro para avaliar sensibilidade mecânica, tolerância à glicose e sensibilidade periférica à insulina e secreção de insulina por ilhotas pancreáticas isoladas estimuladas por diferentes concentrações de glicose. A morfologia do pâncreas e do tumor também foram estudadas. Os dados demonstraram que o desempenho físico foi melhor em ratos que iniciaram o treinamento físico na adolescência, avaliados pela velocidade máxima de corrida e pelo VO2máx. O protocolo de treinamento moderado ou aeróbio diminuiu o índice de caquexia, proliferação celular e crescimento tumoral em ambas as idades, entretanto, foi mais acentuado em ratos treinados na adolescência. Níveis reduzidos de glicemia, insulinemia e melhora da sensibilidade periférica à insulina não foram revertidos nos ratos com tumor Walker-256 que começaram o treinamento na adolescência e parecem estar diretamente relacionados à redução do crescimento tumoral nesses animais. Além disso, o treinamento aeróbio precoce reduziu o conteúdo total de insulina bem como a secreção de insulina estimulada por glicose pelas ilhotas pancreáticas, sem prejudicar a morfologia das ilhotas. Ratos inoculados também apresentaram redução no número de ilhotas pancreáticas, porém, sem alteração na secreção de insulina. A redução da secreção de insulina pelas células beta pancreáticas em animais treinados parece ser o mecanismo responsável por esses resultados e por conferir ao exercício moderado uma nova terapia não farmacológica sensibilizante à insulina para prevenir o crescimento tumoral e doenças relacionadas; Abstract: The present study aimed to evaluate the protective effects of a moderate or aerobic training program performed at different stages of development in Walker-256 tumor growth, and whether there is insulin interference on tumor growth in the proposed animal model. It also aimed to demonstrate biometric, physiological and metabolic changes that could be arised as a result of the treadmill running protocol used and the subsequent tumor inoculation. The maximum oxygen consumption (VO2max), maximum running speed, weight gain, food intake, fat stores, plasma glucose, insulin, triglycerides (TAGs), total and HDL cholesterol levels were evaluated. In addition, experiments in vivo and in vitro were performed to evaluate mechanical sensitivity, glucose tolerance and peripheral insulin sensitivity and insulin secretion by isolated pancreatic islets stimulated by different glucose concentrations. The morphology of the pancreas and tumor were also studied. The data demonstrated that the physical performance was better in rats that initiated the physical training in the adolescence, evaluated by the maximum running speed and the VO2max. The moderate or aerobic training protocol decreased cachexia, cell proliferation, and tumor growth at both ages, however, it was more pronounced in rats who trained in adolescence. Reduced levels of glycaemia, insulinemia, and improvement of peripheral insulin sensitivity were not reversed in Walker-256 tumor bearing rats that began physical training in adolescence and appear to be directly related to reduced tumor growth in these animals. Furthermore, early aerobic training reduced total insulin content as well as glucose-stimulated insulin secretion by pancreatic islets, without impairing the islet morphology. Inoculated rats also presented reduction in the number of pancreatic islets, however, without alteration in insulin secretion. The reduction of insulin secretion by pancreatic beta cells in trained animals appears to be the mechanism responsible for these results and to give moderate exercise and insulin a novel non-pharmacological sensitizing therapy to prevent tumor growth and related diseases

Abstract: The peak speed (Vpeak) is a variable capable of predict running endurance performance and if associated with its time limit (tlim) may be used as a parameter for running training prescription. Besides the variables related to training prescription, it is also necessary to use parameters that are useful for controlling the adequate exercise intensity to be prescribed as well as the possible physiological adaptations associated with training. Within the possibilities, the heart rate variability (HRV), used to indicate parasympathetic nervous system activity, has been applied to make the decisions related to training prescription. Psychological variables are also recommended to complement training control, as well as its effects. Thus, the aim of the present study was to analyze the use of HRV to control training intensity of eight weeks of endurance running training in young untrained women. Thirty women aged 18 to 35 years took part of the study, who were randomized in two groups of 15 women each. The control group (CG) performed training based on a conventional training prescription whereas the other group performed the running training based on parasympathetic nervous system activity (i.e., index rMSSD of HRV) (GHRV). The participants undertook anthropometric assessment, questionnaires to assess dietary pattern, psychological variables (stress, recovery and mood profile), and symptoms related to pre-menstrual syndrome, autonomic modulation (i.e., HRV at rest and heart rate recovery after maximal exercise), physical tests on the treadmill and running performance in a track. It was conducted two tests in the treadmill: an incremental test to determine Vpeak and another one to determine its tlim and the time to complete 5-km running performance (t5km) in a 400-m oficial running track. All the baseline evaluations were performed before (week 1) and after a period of four (week 6) and eight (week 11) of training. The participants performed at least 90% of the 24 training sessions (i.e., three sessions per week) subdivided in moderate intensity continuous training and high intensity interval training. The analysis of variance and effect sizes (ES) were calculated to verify the adaptations to training. The main findings were that the t5km reduced significantly from week 1 to week 11 in both groups (CG = 35.5 ± 5.0 min to 30.5 ± 4.3 min, HRVG = 36.3 ± 4.5 min to 29.8 ± 2.4 min); however, in a greater magnitude in HRVG (ES = large) than in CG (ES = moderate) (ES between-group difference = moderate). The Vpeak also significantly improved in both groups (CG = 11.0 ± 1.4 km·h-1 to 11.9 ± 1.4 km·h-1, HRVG = 10.9 ± 1.2 km·h-1 to 11.9 ± 0.9 km·h-1), with a moderate ES within-group for both groups and a small ES between-group. The tlim at Vpeak increased only in HRVG (5.1 ± 1.3 min to 6.1 ± 1.7 min), with a moderate ES for the between-group differences. In addition, the parasympathetic indexes of HRV at rest improved in HRVG (30.5 ± 9.9 ms to 37.5 ± 13.2 ms and 22 ± 6.9 to 26.7 ± 9.4, respectively) and did not present statiscally significant differences in the CG (ES between-group differences = small for rMSSD and trivial to SD1). The index SD2 increased only in HRVG (77.8 ± 16.3 to 93.6 ± 22.1) with a moderate ES within- and between-groups. The variable representing parasympathetic reactivation (i.e., heart rate recovery) also improved more in the HRVG compared to the CG (CG = 36.9 ± 7.4 bpm to 41.1 ± 7.6 bpm, HRVG = 36.7 ± 9.7 bpm to 42.7 ± 10.7 bpm, ES between-group differences = small). Although the HRVG has performed less moderate intensity continuous training than the CG, this amount of training presented a negative and moderate correlation with changes in performance (i.e., t5km) (r = -0.44). The CG presented improvements on emotional stress (2.0 ± 1.2 to 1.2 ± 0.9), conflicts/pressure (2.9 ± 1.1 to 2.2 ± 1.0), and recovery related to sleep quality (3.1 ± 1.0 to 4.0 ± 0.8), personal accomplishment (2.8 ± 1.7 to 3.7 ± 1.4), self-regulation (3.3 ± 1.3 to 4.1 ± 1.2), mean specific recovery (3.1 ± 1.2 to 3.7 ± 1.0) and mean total recovery (3.2 ± 0.9 to 3.6 ± 0.9). On the other hand, the HRVG improved general stress (1.6 ± 1.1 to 1.1 ± 0.6), emotional stress (2.0 ± 1.0 to 1.4 ± 0.7), social stress (1.6 ± 1.1 to 0.8 ± 0.5), lack of energy (2.2 ± 1.0 to 1.4 ± 0.8), mean general stress (2.1 ± 0.8 to 1.6 ± 0.4) and self-regulation (3.1 ± 1.0 to 3.9 ± 1.1). Additionally, the HRVG also improved mood state on the scales tension (6.1 ± 5.1 to 3.3 ± 3.2), depression (4.9 ± 4.3 to 2.2 ± 2.1), anger (9.7 ± 3.6 to 6.9 ± 2.9), fatigue (7.9 ± 3.5 to 5.3 ± 2.0) and total mood disturbance (28.5 ± 16.3 to 17.8 ± 6.6). The CG reduced vigour (8.9 ± 3.6 to 6.9 ± 3.0), which was not observed in the HRVG. The variation in Vpeak after training presented a large correlation with the variation in t5km (r = -0.65). It is concluded that 1) the endurance running training based on HRV presented greater improvements in the 5 km performance than the conventional/standardized training program, as well as for the autonomic modulation; 2) The training based on HRV also improved mood profile and stress-related aspects that were not improved in the CG; 3) the percentage variation of Vpeak after training was the one that presented the highest correlation with changes in 5 km performance.2016-01-01T00:00:00ZTreinamento de corrida de endurance associado à aplicação de LED: efeitos em variáveis de desempenho, marcadores de estresse oxidativo e dor muscular em homens jovens não treinadosPeserico, Cecília Segabinazihttp://repositorio.uem.br:8080/jspui/handle/1/21432018-10-26T17:54:28Z2016-01-01T00:00:00ZTítulo: Treinamento de corrida de endurance associado à aplicação de LED: efeitos em variáveis de desempenho, marcadores de estresse oxidativo e dor muscular em homens jovens não treinados

Abstract: With the purpose of optimizing the adaptations obtained from the running endurance training, the LED application has been used in order to accelerate the muscle recovery and as an ergogenic resource for the oxidative metabolism. However, little is known about the longitudinal effect of LED application associated with endurance training on performance parameters, oxidative stress responses and muscle soreness. Therefore, the aim of this study was to examine the effects of eight weeks of running training, prescribed by the peak velocity (Vpeak) and its respective time limit (tlim) associated with LED application on performance variables, oxidative stress markers and muscle soreness in untrained young men. Thirty young and untrained men participated in this study, who were divided into a control group (CG) and LED group (LEDG) with 15 participants each group. Both groups perfomed a training protocol during eight weeks, wherein the LEDG had the LED application and CG no. The LED was applied immediately before all training sessions in both legs, respecting the absence or presence of light emission for each group. Participants perfomed evaluations on three moments: at week 1 (W1), after the first four weeks of training (weeks 2-5) at 6th week (W6) and after the last four weeks of training (weeks 7-10) at 11th week (W11). Performance evaluations were: tests to determine Vpeak and tlim and 5-km time trial. It was collectect, in the morning, 6 ml of venous blood to analyze the oxidative stress markers: malondialdehyde (MDA) in plasma, antioxidant enzymes catalase (CAT) and superoxide dismutase (SOD) in erythrocytes, the total glutathione concentrations, reduced (GSH) and oxidized (GSSG); it was also evaluated muscle soreness through the visual analogic scale before and after all training sessions. The comparisons between groups and the moments W1, W6 and W11 was made by mixed ANOVA for repeated measures followed by Bonferroni as a post hoc test for multiple comparisons; it was calculated the percentage (%) of change and the effect sizes (ES) to express the magnitudes of changes during the trainining period. Statistical significance was set at P < 0.05. The results showed that the Vpeak increased significantly in both groups (CG: W1 = 13.4 ± 1.1, W11 = 14.4 ± 1.0 km∙h-1; LEDG: W1 = 13.4 ± 1.2, W11 = 14.6 ± 1.0 km∙h-1); the 5-km test duraiton (T5-km) decreased significantly in both groups, but this decrease was more expressive in the LEDG (W1 = 27.6 ± 3.0, W11 = 23.9 ± 2.2; -13.1 ± 5.2%) compared to CG (W1 = 27.0 ± 3.3, W11 = 24.1 ± 2.5; -10.3 ± 4.2%). After the training period the MDA concentrations remained similar in both groups (CG: W1 = 0.409 ± 0.464, W11 = 0.411 ± 0.357 nmol/MDA ml; LEDG: W1 = 0.307 ± 0.224, W11 = 0.310 ± 0.241 nmol/MDA ml) but with greater magnitude of increase in the CG compared to LEDG (274.3 ± 556.3% vs 66.7 ± 205.4%). In the LEDG it was observed an increase in the activities of enzymes CAT (W1 = 49.62 ± 25.35, W11 = 53.83 ± 29.94 U/mg Hb) and SOD (W1 = 1.06 ± 0.58, W11 = 1.33 ± 1.00 U/mg Hb), while in the CG these enzymes decreased (CAT: W1 = 63.51 ± 29.83, W11 = 45.00 ± 25.43 U/mg Hb; SOD: W1 = 1.18 ± 0.51, W11 = 1.04 ± 0.57 U/mg Hb), however, without significant differences in the comparison W1 vs W11. For GSSG there was a decrease in LEDG (W1 = 56.3 ± 83.4, W11 = 9.81 ± 4.76 μmol/g Hb) and an increase in the CG (W1 = 8.48 ± 2.94, W11 = 12.42 ± 7.90 μmol/g Hb), with significant difference between the % change values (W1 vs W11) of the groups (-13.5 ± 30.3% vs 56.3 ± 83.4%); furthermore, it was demonstrated a greater magnitude of increase in the GSH/GSSG ratio in the LEDG (W1 = 1.20 ± 0.44, W11 = 1.53 ± 0.40, 39.4 ± 55.7%, moderate ES) compared to CG (W1 = 1.26 ± 0.44, W11 = 1.36 ± 0.45; 24.9 ± 62.6%; small ES) after the training period. In the last three weeks of running training there was a tendency of lower increases in the post-session muscle soreness scores (i.e, absolute difference pre vs post-session) in the LEDG (values between 2.0 ± 2.1 and 2.1 ± 2.1 cm) compared to CG (values between 2.7 ± 2.3 and 3.1 ± 2.6 cm), with small ES in the comparison between groups for these scores. We concluded that the running endurance training associated with LED application had positive effects on improving the 5-km performance, decrease oxidative stress, increase the antioxidant defense and attenuate muscle soreness in untrained young men.2016-01-01T00:00:00Z
