ABSTRACT The present study related to boxing athletes' mental toughness and physical fitness performances with Big Five Factors. For this, the sample was composed of eleven recreational boxers who competed at the state level and were regularly training (technical and tactical) 4 times a week during the evaluation period. The 44-item Big Five Inventory (BFI) measures the Big Five dimensions of Conscientiousness, Agreeableness, Neuroticism, Openness, and Extraversion and the 14-item Sports Mental Toughness Questionnaire (SMTQ) were applied with Strength, Power, and Endurance Tests, Pearson and Spearman's correlations were used to verify the association between BFI, physical and mental tests, respectively, p≤.05. Our results demonstrated that significant and strong correlation between agreeableness factor and sit-ups test, with 40.85±12.36 freq./min (r=.72, p=.02) and, in SMTQ, a strong correlation between Neuroticism and Control [10(9;12) score, r=.76, p≤0.01], Constancy [10(9;12) score, r=.84, p≤0.01] and Total SMQT [37(34;37) score, r=.84, p≤0.01]. In conclusion, these results suggest that Neuroticism factors are associated with mental toughness, while the agreeableness factor is related to muscular endurance capability. Mental toughness and endurance results are associated with boxers' personalities whose drive motivates them relentlessly towards success and promotes thriving in boxing training environments or during championships. athletes Factors this technical tactical period 44item item 44 BFI (BFI Conscientiousness Agreeableness Openness 14item 14 SMTQ (SMTQ Strength Power Tests Spearmans Spearman s tests respectively p05 p 05 p≤.05 situps sit ups test 40851236 40 85 12 36 40.85±12.3 freqmin freq min r=.72, r72 r 72 (r=.72 p=.02 p02 02 10912 10 9 [10(9;12 score r76 76 r=.76 p≤0.01, p001 p≤0.01 , 0 01 r84 84 r=.84 373437 37 34 [37(34;37 p≤0.01. . conclusion capability championships 1 p0 p≤.0 4085123 8 3 40.85±12. r=.72 r7 7 (r=.7 p=.0 1091 [10(9;1 r=.7 p00 p≤0.0 r8 r=.8 37343 [37(34;3 p≤. 408512 40.85±12 (r=. p=. 109 [10(9; r=. p≤0. 3734 [37(34; p≤ 40851 40.85±1 (r= p= [10(9 r= p≤0 373 [37(34 4085 40.85± (r [10( [37(3 408 40.85 [10 [37( 40.8 [1 [37 40.

RESUMO O presente estudo relacionou a resistência mental e o desempenho da aptidão física de atletas de boxe com os cinco grandes fatores. Para isso, compuseram o presente estudo onze boxeadores recreativos que competiram em nível estadual e estavam treinando regularmente (técnico e tático) 4 vezes por semana durante o período de avaliação. O Big Five Inventory (BFI) de 44 itens mede as dimensões de Conscienciosidade, Amabilidade, Neuroticismo, Abertura e Extroversão e o Questionário de Resistência Mental Esportiva (SMTQ) de 14 itens foram aplicados com Testes de Força, Potência e Resistência, Pearson e as correlações de Spearman foram utilizadas para verificar a associação entre IMC, testes físicos e mentais, respectivamente, p≤0.05. Nossos resultados demonstraram correlação significativa e forte entre o fator de amabilidade e o teste de abdominais, com 40,9±12,4 freq./min (r=0,72, p=0,02) e, no SMTQ, uma forte correlação entre Neuroticismo e Controle [10 (9;12) pontuação, r=0.76, p≤0,01], Constância [10(9;12) pontuação, r=0.84, p≤0,001] e total SMQT [37(34;37) pontuação, r= 0.84, p≤0,001]. Em conclusão, esses resultados sugerem que os fatores de neuroticismo estão associados à resistência mental, enquanto o fator de amabilidade está associado à capacidade de resistência muscular. Os resultados de resistência mental e resistência estão associados à personalidade dos boxeadores, cuja motivação os impulsiona implacavelmente para o sucesso e promove o sucesso em ambientes de treinamento de boxe ou durante campeonatos. isso técnico tático avaliação BFI (BFI Conscienciosidade Amabilidade SMTQ (SMTQ 1 Força IMC mentais respectivamente p005 p 0 05 p≤0.05 abdominais 409124 40 9 12 40,9±12, freqmin freq min r=0,72, r072 r 72 (r=0,72 p=0,02 p002 02 10 [1 912 (9;12 pontuação r076 76 r=0.76 p≤0,01, p001 p≤0,01 , 01 p≤0,01] 10912 [10(9;12 r084 84 r=0.84 p≤0,001 p0001 001 373437 37 34 [37(34;37 084 0.84 p≤0,001. . conclusão muscular campeonatos p00 p≤0.0 40912 40,9±12 r=0,72 r07 7 (r=0,7 p=0,0 [ 91 (9;1 r=0.7 p≤0,0 1091 [10(9;1 r08 8 r=0.8 p≤0,00 p000 00 37343 3 [37(34;3 08 0.8 p0 p≤0. 4091 40,9±1 r=0,7 r0 (r=0, p=0, (9; r=0. p≤0, 109 [10(9; 3734 [37(34; 0. p≤0 409 40,9± r=0, (r=0 p=0 (9 r=0 [10(9 373 [37(34 p≤ 40,9 (r= p= ( [10( [37(3 40, (r [37( [37 [3

Abstract The present study is a descriptive-documental study that evaluates a survey database about Brazilian Jiu-Jitsu (BJJ) practitioners and concussions. We investigate any relationship between lifetime practice and the incidence of concussions in adults. For this, an online survey composed of 17 questions was sent to 42 BJJ coaches. The Survey Monkey platform was used to host the survey. Some demographic data was collected, followed by questions related to the BJJ practice. A total of 791 practitioners had completed or partially answered the survey. The results show that concussions are more frequent at the beginner’s white 49.0% and blue belt 33.3% (p ≤ 0.01). The symptom “seeing stars” showed a positive and significant correlation (r = 0.169, p ≤ 0.002) with a white and blue belt. After a concussion, white and blue belts return faster than the others (χ2 = 190.964; p ≤ 0.01). White, blue, and purple belts are the least likely to seek medical care after a concussion (χ2 = 14.874; p ≤ 0.01). Together, our results showed the need for an educational intervention with the BJJ coaches and beginners regarding awareness about concussions and possible post-traumatic issues and creating procedures to deal with concussions in BJJ.

ABSTRACT The actions of time-motion in combat sports have been the subject of scientific investigations, aiming to develop analysis protocols. This study aimed to develop and validate a specific time-movement protocol for English Boxing using the Frami® software. This protocol was developed based on English boxing techniques. Groups of actions and patterns were defined from the beginning to the end of each action. Twelve combats carried out in the Rio de Janeiro Olympics were analyzed for validation. Test and retest comparisons were made using the Intraclass Correlation Coefficient (ICC), both considering a significance level of p≤ 0.05. The main results indicated that there was reproducibility classified as excellent for all variables (Displacement: CCI= 0.99 and 0.97; Attack: CCI= 0.98 and 0.96; Defense: CCI= 0.97 and 0.94; Clinch: CCI= 0.99 and 0.96; pause: CCI= 0.98 and 0.96; CCI= 1.0 and 0.99, for the 1st and 2nd evaluators respectively and; Total time ICC= 1.0 for both evaluators). There was excellent objectivity (ICC≥ 0.98) in all groups of actions. It can be concluded that the developed protocol proved to be valid and reproducible for analyzing boxing matches.

RESUMO As ações de tempo e movimento nos esportes de combate tem sido objeto de investigações cientificas, com fins de desenvolvimento de protocolos de análise. Este estudo teve por objetivo desenvolver e validar um protocolo tempo-movimento especifico para o Boxe Inglês, utilizando o software Frami®. O presente protocolo foi desenvolvido sobre técnicas do boxe inglês, foram definidos grupos de ações e padrões de início o final de cada ação. Para validação foram analisados 12 combates realizados nas Olimpíadas do Rio de Janeiro. As comparações de teste e reteste foram feitas usando o Coeficiente de Correlação Intraclasse (CCI), ambos considerando um nível de significância de p≤ 0,05. Os principais resultados indicaram que houve reprodutibilidade classificada como excelente para todas as variáveis (Descolamento: CCI= 0.99 e 0.97; Ataque: CCI= 0.98 e 0.96; Defesa: CCI= 0.97 e 0.94; Clinch: CCI= 0.99 e 0.96; pausa: CCI= 1 e 0.99, para o 1º e 2º avaliador respectivamente; Tempo total CCI= 1 para ambos os avaliadores). Houve objetividade excelente (CCI≥ 0.98) em todas os conjuntos de ações. Pode-se concluir que o protocolo desenvolvido se mostrou válido e reprodutível para analisar de combates de boxe.
