Resumo
Introdução e objetivo: Este estudo teve como objetivo investigar os estados emocionais, a percepção de estresse e a ritimicidade do cortisol salivar ao longo do dia, no contexto da escalada guiada em rocha, no estilo à vista (EG) e red point (ER). Métodos: Os participantes foram entrevistados utilizando-se, no primeiro momento, um roteiro previamente validado por três professores doutores, contendo quatro eixos temáticos definidos a priori. Num segundo momento, responderam o questionário de estresse percebido (QEP) e forneceram amostras salivares obtidas durante dois dias de escalada (EG e ER) e um dia de repouso (R), nos horários 6 h, 12 h, 19 h e 22 h e antes e após as escaladas e antes e após a realização do procedimento de segurança dos escaladores. A concentração de cortisol salivar (CCS, ng/mL) foi avaliada por ensaio imunoensimático (EIA). Estatística descritiva, com medidas de tendência central, média e erro padrão, ANOVA seguida por Tukey, significativo quando p<0,05. Resultados: Participaram da entrevista semi estruturada, primeira etapa da pesquisa, nove voluntários (n=9). No eixo fatores emocionais, a influência da família, amigos e grupo organizados foram determinantes pela escolha deste esporte. No que tange ao eixo de resolução de problemas, os escaladores demonstram-se resilientes e adotam um estilo de enfrentamento capaz de superar todos os desafios decorrentes da escalada com planejamento e treinamento. Os estados emocionas de estresse apresentados, dizem respeito ao prazer que a atividade da escalada proporciona e a presença do medo com sentido positivo. No segundo momento (n=5), a percepção de risco dos escaladores escalada guiada à vista foi descrito como baixa. As características do grupo são, peso de 66,68±4,96 (kg); estatura 174,0±3,81 (cm); índice braço antebraço...
Introduction and Objective: This study aimed to investigate the emotional states, perception of stress and behavior of salivary cortisol in the context of guided rock climbing on sight (EG) and red point (ER) styles. Methods: : Participants were interviewed using first, a questionnaire previously validated by three referees containing four thematic áreas, a priori defined. Secondly, answered the questionnaire of perceived stress (QEP), anthropometric, body composition and salivary samples obtained during two days of climbing, on EG and ER and a day of rest (R), the time 6h, 12h, 19h and 22h, before and after the climb. All saliva samples were analyzed by immunohistochemistry and results processed by descriptive statistics and ANOVA with post test for Turkey 95% significance. Results: The semistructured interview, the first stage of the study, nine volunteers (n = 9), the influence of family, friends and organized group are emotional factors determinants by the choice of this sport. To the axis of resilience, climbers show up resilient and adopt a style of coping able to overcome all the challenges of climbing with planning and training. The emotional states of stress presented relate to the pleasure and fear with a positive sense. In the second stage of research (n = 5), the risk perception of climbers on sght guided climbing was described as low. The characteristics of the group are, weight of 66.68±4.96 (kg), height 174.0±3.81 (cm), forearm arm index was 9.3±0,39, and fat percentage of 8.35±1.39%. The mean values of QEP was 0,21±0,04. For salivary cortisol concentrations obtained the following results on different days: On R, the concentrations obtained at the times of 12pm (10±1.90 ng/mL), 19h (7±0.87 ng/mL) and 22h (5±0.64 ng/mL) were significantly different from 6 hours (19±3.07 ng/mL). On EG in concentrations obtained... (Complete abstract click electronic access below)
