Clinical and blood gasometric parameters during Vaquejada competition

ABSTRACT: Clinical and complementary analysis are good alternatives to evaluate physiological demand in performance horses. The aim of this study was to assess whether the physical effort variation of the three-day Vaquejada competition (a Brazilian form of bullfighting) reflected in clinical and blood gasometric changes. During the competition eight sprints have been performed on the first day (D1), eight on the second (D2) and three on the last one (D3). Ten horses were evaluated by checking heart and respiratory rates and collecting blood samples for use in portable chemistry analyzer. Through that, it was assessed potential of hydrogen ion (pH), carbon dioxide pressure (pCO2), bicarbonate (HCO3-) and titratable base concentration (cBase). Evaluations were carried with resting of at least twenty hours, before physical activity (D0), as control parameter, and up to thirty minutes after each sprint. Clinical parameters have increased on D1, D2 and D3, when compared to D0, which demonstrated the increased demand for substrate and oxygen to the cells.. Blood gasometric trial showed reductions of all variables, most marked between D1 and D2. It was verified less alteration of all clinical and blood gasometric parameters in D3 against D0. We concluded that the change effort between days of competition influenced the clinical and blood gas parameters, demonstrating appropriate physiological response. The data were presented as mean and standard error of the mean (mean ± SEM) obtained in different days. Normality was confirmed by the Kolmogorov-Sminov test and data were compared by one-way ANOVA, followed by post-test Holm-Sidak (GraphPad Prism 2.6 for Windows, GraphPad Software, San Diego, CA, USA). P≤0.05 was considered as statistically significant.

O "espetáculo do cabra macho" : um estudo sobre os vaqueiros nas vaquejada no Rio Grande do Norte

This body of work discusses the gender meanings associated with cowboys while endorsing contemporary rodeos in Rio Grande do Norte as a recreational sport and a form of ludic expression. As a result, this research has focused on rodeo practices, aiming to understand the different aspects emphasizing masculinity: these associations being constructed through relationships, contexts and the competitiveness between participants. These gender meanings hinge on the desire for a wining performance and on the behaviour exhibited among cowboys outside the competitive ring in specific social settings such as parties and recreational time. The latter were the focus of the ethnographic research; direct observation and semistructured interviews with cowboys in rodeo stadiums were also used. Through qualitative analysis of the collected data, it was revealed that historically and socially different trajectories do not immediately cause a gender crisis in cowboys, but the assignment of new significance by the social acts in each historical context. However, the presence of cowboys leads to other models of masculinity configured by expressions and the insertion of new personas, not coming directly from field activities, but imbued by the symbolic elements of the cowboy persona, constructed throughout history

O VAQUEIRO E A VAQUEJADA: DO TRABALHO NAS FAZENDAS DE GADO AO ESPORTE NAS CIDADES

Esse artigo aborda sobre as transformações na vida dos vaqueiros, dos sertões nordestino, que tinham como um dos divertimentos as festas de apartação no pátio das fazendas. Esses eventos são tidos como à gênese das vaquejadas moderna. Dessa forma, procuramos demonstrar as relações de trabalho existente nessa atividade, quando era praticada apenas nas fazendas, e hoje nos parques de vaquejada. Tal atividade que antes era tida como rural, hoje já faz parte do cotidiano das grandes cidades do nordeste e do Brasil. Diante de tal expansão, fazemos análise geográfica e histórica da vida desse personagem. O texto está divido em três partes, a primeira as “pegadas de boi”, a segunda as “vaquejadas de morão” e a terceira a vaquejada moderna.
