Successful performance in grappling combat sports (GCS) can be influenced by the fighter's capacity to sustain high-intensity contractions of the handgrip muscles during combat. This study investigated the influence of GCS experience on the critical torque (CT), impulse above CT (W′), tolerance, and neuromuscular fatigue development during severe-intensity handgrip exercise by comparing fighters and untrained individuals. Eleven GCS fighters and twelve untrained individuals participated in three experimental sessions for handgrip muscles: (1) familiarization with the experimental procedures and strength assessment; (2) an all-out test to determine CT and W′; and (3) intermittent exercise performed in the severe-intensity domain (CT + 15%) until task failure. No significant differences were found in CT and neuromuscular fatigue between groups (p > 0.05). However, GCS fighters showed greater W′ (GCS fighters 2238.8 ± 581.2 N·m·s vs. untrained 1670.4 ± 680.6 N·m·s, p < 0.05) and exercise tolerance (GCS fighters 8.38 ± 2.93 min vs. untrained 5.36 ± 1.42 min, p < 0.05) than untrained individuals. These results suggest that long-term GCS sports training can promote increased tolerance to severe-intensity handgrip exercise and improved W′ without changes in CT or the magnitude of neuromuscular fatigue.

In this book, the author presents the Black Brazilian Movement as a political actor, educator, producer of emancipatory knowledge and systematizer of the same one about the racial question in Brazil. Such knowledge, when transformed into claim, became important State policies in the twenty-first century. It is, therefore, a social movement of great importance for the unveiling of questions such as racial discrimination, gender, youth, affirmative actions, africanities, education of ethnic-racial relations, among many others. Nilma Gomes emphasizes the epistemological richness of this movement in the perspective of education, privileging as a theoretical support the contributions of Boaventura de Sousa in the re-signification of concepts as pedagogies of absences and of the emergencies. ; Neste livro a autora apresenta o Movimento Negro Brasileiro como um ator político e educador, produtor de saberes emancipatórios e sistematizador de conhecimentos acerca da questão racial no Brasil. Tais saberes, ao transformarem-se em reivindicações, tornaram-se importantes políticas de Estado no século XXI. Trata-se, assim, de um movimento social de suma importância para o desvelamento de questões como discriminação racial, gênero, juventude, ações afirmativas, africanidades, educação das relações étnico-raciais, dentre tantas outras. Nilma Gomes enfatiza a riqueza epistemológica deste movimento na perspectiva da educação, privilegiando como aporte teórico as contribuições de Boaventura de Sousa na ressignificação de conceitos como pedagogias das ausências e das emergências.
