ABSTRACT Marajoara Wrestling (MW) is a combat sport that has been not sufficiently investigated. Characterised as a grappling fight, MW demands peculiarities that are still not well known, such as the relationship between physical constitution and the use of competitive techniques. The present study aimed to analyse the technical-tactical performance of the MW in terms of techniques used and combat configuration. This was a cross-sectional observational study from a sample of three male athletes aged between 23 and 33 years. Athletes were filmed in a natural environment during simulated MW combat in order to raise some technical elements of the MW, such as: defensive attitudes, attack technique, takedown and ground fighting. The results allowed the following conclusions: there is no technical-tactical standard in MW, but a combination of elements involving technical-tactical collection, practice time and anthropometric indicators; temporal and functional elements are configured from one’s place of practice; the halter is the most frequent technique, being widely used when combined with other techniques; the defensive work is very similar among athletes, the same does not happen in relation to the ground fight, where differences were observed in the fight configuration. This study is expected to be useful in proposing training programs aimed at the technical-tactical performance of the MW.

RESUMO A Luta Marajoara (LM) é uma modalidade esportiva de combate ainda pouco investigada. Caracterizada como luta de agarre, a LM demanda peculiaridades ainda pouco conhecidas, como a relação entre a constituição física e uso de técnicas competitivas. O estudo tem como objetivo analisar o desempenho técnico-tático da LM em termos de técnicas utilizadas e configuração dos combates. Trata-se de um estudo transversal e observacional realizado a partir de uma amostra constituída por três atletas masculinos com idades entre 23 e 33 anos. Os atletas foram filmados em ambiente natural durante um combate simulado de LM na perspectiva de levantar alguns elementos técnicos da LM, tais como: atitudes defensivas, técnica de ataque, queda e luta de solo. Os resultados permitem as seguintes conclusões: Não existe um padrão técnico-tático em LM e sim uma combinação de elementos envolvendo, acervo técnico-tático, tempo de prática e indicadores antropométricos; Elementos temporais e funcionais são configurados a partir de seu local de prática; A cabeçada é a técnica mais frequente, sendo muito utilizada quando combinada com outras técnicas; O trabalho defensivo é muito similar entre os atletas, o mesmo não acontece em relação à luta de chão, onde se observou diferenças na configuração da luta. Espera-se que o estudo possa ser útil na proposição de programas de treinamento voltados ao desempenho técnico-tático da LM.

Abstract The objective of this study was to perform a meta-analysis of publications that reported the association between dispositional optimism and depression during youth, analyzing if the strength of this relationship varied according to potential factors. Systematic searches were carried out in APA PsycNet, Virtual Health Library, Embase, Web of Science, PubMed Central, and Scopus to collect English, Portuguese, or Spanish studies from 2009 onwards. Two reviewers selected the eligible articles, assessed the quality of each study, and extracted the data. For the synthesis of the results, a meta-analytic approach was used. We identified 4077 publications in the initial searches and 22 in the supplementary searches, from which 31 studies remained for analysis once the eligibility criteria were applied. The results showed a statistically significant negative association between dispositional optimism and depression in the young population, age being a factor that modifies the effect measure between these variables. This meta-analysis provides a consistent and robust synthesis on the interaction effect between dispositional optimism and depression in the young population. Based on these findings, early clinical admissions may effectively improve optimistic tendencies in young people, which could help them prevent depressive symptoms or episodes.
