Abstract Aims: This study aimed to present a technical evaluation proposal for the crawl stroke that can be used with large groups of swimmers, based on an observation sheet. Methods: Fifteen healthy university students aged between 18 and 30 years were chosen to participate in the study. The subjects were recorded swimming at a distance of 50 meters using the crawl technique at a comfortable and self-determined speed. The recordings simulated docent observation capacity. Five swimming teachers were selected to evaluate the proposed checklist and the subjects’ technique. An observation sheet was created based on references present in literature containing ten items that are considered fundamental for swimming movements. The study was divided into (i) checklist validation, (ii) intra-evaluator consistency, and (iii) inter-evaluator consistency. Results: The proposed checklist fulfilled the validity criteria, with intra-evaluator consistency varying between reasonable and substantial, with k varying between 0.36 and 0.73 respectively, while inter-evaluator consistency was deemed reasonable (k = 0.24). Conclusion: According to the results that were obtained, the suggested list is valid and adequate for what it proposes to do.

FUNDAMENTOS: A radiação ultravioleta tem sido considerada um dos mais importantes fatores de risco para o câncer de pele melanoma ou não melanoma. Dessa forma, tem sido aceito que os profissionais que trabalham em atividades ao ar livre apresentam maior risco de desenvolver câncer de pele. OBJETIVO: Identificar os hábitos relacionados à exposição solar dos professores de Educação Física (EF) que trabalham com atividades aquáticas. MÉTODOS: Realizou-se um estudo observacional do tipo transversal com 123 professores de EF, de ambos os sexos, que trabalham com atividades aquáticas, no mínimo, há um ano, com idades entre 20 e 58 anos, utilizando-se um questionário com perguntas abertas e fechadas. RESULTADOS: Do total de informantes, observou-se que 64,2% trabalham diretamente expostos ao Sol e 13,0%, em piscinas com cobertura parcial, dos quais 69,5% o fazem entre 10h e 16h. Do grupo exposto ao Sol, verificou-se que apenas 17,9% sempre se protegem: 14,3% dos homens e 23,1% das mulheres. Contudo, não houve diferenças estatísticas significativas. CONCLUSÕES: A partir dos dados coletados, é possível concluir que o grupo amostral estudado parece encontrarse em situação de risco diante da possibilidade de desenvolver câncer de pele

BACKGROUND: Ultraviolet radiation has been considered one of the most important risk factors for melanoma or nonmelanoma skin cancer. Thus, it has been accepted that professionals working with outdoor activities are at greater risk of developing skin cancer. OBJECTIVE: To identify sun-exposure habits among teachers of physical education (PE) who work with water activities. METHODS: We conducted an observational cross-sectional study with 123 male and female PE teachers aged between 20 and 58 years who have been working with water activities for at least a year using a questionnaire with open and closed-ended questions. RESULTS: Of the respondents, it was observed that 64.2% work directly exposed to the sun and 13.0% in partially covered pools; out of these, 69.5% do so between 10 am and 4 pm. In the group exposed to the sun, it was found that only 17.9% always protect themselves. Men seem to be less careful, since 14.3% always protect themselves, while 23.1% of the women reported to always protect themselves. However, there were no statistically significant differences. CONCLUSION: Based on the data collected, we conclude that the sample investigated may be at risk of developing skin cancer
