Item Acesso aberto (Open Access) Determinantes do ganhar ou perder em humanos: um estudo com atletas de judô(Universidade Federal do Pará, 2017-02-17) CAMPOS, Ítalo Sérgio Lopes; GOUVEIA JUNIOR, Amauri; http://lattes.cnpq.br/1417327467050274In the sports environment experiences of success or failure are often experienced by different individuals in the most varied environments. Attempting to explain how an individual deals with victory or defeat in behavioral terms will depend on a number of factors, including athlete's history, status (environment), fitness (ability to perform), and athletic maturity). The general objective of the thesis was to systematize a theoretical model about the determinants of winning and losing in judo. For this purpose, we sought to verify (through documentary analysis) if results of previous fights are decisive for the maintenance of subsequent victories and / or defeats; in sequence the study analyzed judo from a competition situation seeking to describe in real time, possible quantitative and qualitative interactions of the fight. According to the design of this study, it was evidenced that the ability (performance related to fight), allied to athlete's athletic maturity (experience in the modality) were the factors that most potentiated the process of winning or losing. This assertion is based on the results of articles published from the construction of the thesis, that is, sports determine and condition morphofunctional characteristics that are related to the demands of the sports environment; Athletes' previous experiences (victory or defeat) can determine subsequent results even in a short space of time; The training time and the morphofunctional factors are strong determinants for the outcome of the fights. These data corroborate and signal that the trainability seems to be one of the factors that differentiates winners and losers in the results obtained in this study.Item Acesso aberto (Open Access) Pez-cebra (Danio rerio) como modelo de bienestar animal(Universidade Federal do Pará, 2022-10) VASQUEZ, Jhon Jairo Buenhombre; GOUVEIA JUNIOR, Amauri; http://lattes.cnpq.br/1417327467050274; https://orcid.org/0000-0003-1710-9662Zebrafish has become an important model for various disciplines such as neuroscience and the testing of new pharmacological molecules. Therefore, the way in which it is housed and the consequences of its accommodation on its well-being represent an important aspect to study. Very few studies have evaluated the effect of environmental enrichment on the welfare of zebrafish and its negative or positive impacts have yet to be elucidated. An important challenge is to establish the consequences not only of the presence of enrichment but also of its loss. Likewise, the form of presentation of a stimulus, either predictably or unpredictably, influences the physiological and behavioural responses of the animal. Therefore, the form of presentation of the enrichment represents another important aspect to assess. The evaluation of emotional (affective) states is crucial for the study of zebrafish welfare, in particular to evaluate the influences of the environment on the animal. However, directly assessing these states is difficult due to their subjective nature. Therefore, the current approach focuses on estimating them from the resulting physiological and behavioral components. Today there are robust standardized tests that assess and correlate neuroendocrine responses with well-established behavioural assessment criteria for stress and anxiety in zebrafish. However, there are no similar tests to measure positive emotional states in this species. An alternative metric to assess both the positive and negative affective states of animals is the cognitive bias. These tests allow researchers to infer an individual's emotional state from cognition. Therefore, the evaluation of apparently negative (Unpredictable conditions and absence or loss of enrichment) and positive ones (Predictable conditions and presence or gain of enrichment) accommodation contrasts through a type of cognitive bias (cognitive judgment bias (CJB) in zebrafish may constitute a promising model to understand the effects of housing on affective states and well-being in this fish. Additionally, it has been shown that individual variations such as personality influence the central nervous system, behaviour and cognitive judgment bias results in other species. These differences and their impacts on zebrafish have not yet been studied. Consequently, the general objective of this thesis was to establish if the cognitive judgment bias can be used in zebrafish for the evaluation of positive and negative emotional states produced by environmental modifications and its relationship with personality.Item Acesso aberto (Open Access) A tomada de decisões no judô: o que se diz e o que se faz? Relação entre tomada de decisões e perfil neurocognitivo(Universidade Federal do Pará, 2023-03) RIVERA, Luis Felipe Sarmiento; GOUVEIA JUNIOR, Amauri; http://lattes.cnpq.br/1417327467050274; https://orcid.org/0000-0003-1710-9662There are two ways to think about how the decision process is done. The process can be automatic and having psychomotor characteristics, or mediated by linguistic process -in a deliberated way-. Moreover, martial arts bring an environment with high emotionality, where the anxiety is present. The objective of this study is to understand how the decision-making process, the anxiety and the impulsivity is presented in a combat physical activity, a Judo fight, that demands constant decisions and responses with limited time. To do this, there were to groups of participants (30 judo fighters and 15 non-fighters). One of the groups watch a video and anticipated the fighter’s movement with a questionary, and the other group was recorded in a judo fight. Both groups also performed an impulsivity test and an anxiety test. Each participant had more than 4,5 years of training and was an active competitor. There were found differences in the decisions made by the participants in the fight and the decisions that the participants told they would perform, specifically, when they were going to execute and action. Moreover, there was a significant difference in the anxiety levels of the group of fighters compared to controls, where the fighters had higher anxiety levels than controls. There were none significative differences in impulsivity between the groups. The results of the study shown how is cognition in Judo fighters, indicating where to focus the training and competition programs of the fighters.
