Rugby union has one of the highest injury incidence rates in team sports, however, most of the available data focus on the epidemiology of injuries in countries where rugby is popular. We aimed to report the incidence rate and relevant epidemiological aspects of injuries occurred in a group of Portuguese male rugby players. A prospective cohort study was conducted with a group of 45 senior and 32 under-18 male players (total of 77 players). Outcome measures included injury incidence, position, type, location and severity of injuries. The match injury incidence for all players was 55.84 per 1000 player match-hours (66.66 for seniors, 42.85 for under-18), while mean time-loss for injury was 20.79 days. No statistical differences were found between groups. Lower limb injuries accounted for 60.5% of all injuries, while joint/ligament injuries were the most prevalent type. Contact events were responsible for 65.1% of injuries. Despite the limitations, the obtained data are consistent with the literature. Time-loss injuries seem highly prevalent in rugby union and the incidence rates found in this Portuguese-based study were lower than the reported for international and senior men’s professional rugby union, but higher than those occurring in community rugby in tier-1 countries. The authors believe these data reinforce the need to develop and implement effective injury surveillance and prevention programs.

Injury incidence rates in rugby sevens are higher than those reported for the 15-a-side variant, at the same level of competition. Injuries are also more severe, resulting in longer absence periods. This might result from the fact that rugby sevens is played with greater speed, leading to an increase in energy transfers during tackles, more running and turning manoeuvers, that can possibly cause more severe injuries.

Injury incidence in our study is similar to that reported for international sevens, although severity is lower. An association between training loads and the occurrence of injuries was found for both tiers, although with differential results, thus reinforcing the need to customize players' preparation. Further studies at non-elite competitions are needed to gather significant data to accurately formulate future injury prevention protocols or recommend modifications to game laws or competition formats, aiming at players' welfare.

INTRODUÇÃO: No rugby, cada posição apresenta exigências muito específicas e distintas, tanto em nível antropométrico como fisiológico. Os diferentes estudos publicados revelam a existência de diferenças significativas em nível das características antropométricas e fisiológicas dos atletas de rugby das diferentes posições. Apesar de comuns em países onde a modalidade é mais popular, nenhum estudo procurando caracterizar o atleta de rugby português foi, até agora, publicado. OBJETIVOS: Caracterizar antropométrica e fisiologicamente os atletas de rugby portugueses, procurando identificar eventuais diferenças entre atletas de grupos posicionais distintos. Comparar os resultados obtidos com os demais trabalhos já publicados. MÉTODOS: Avaliamos 46 jogadores de rugby de duas equipes a disputarem competições nacionais seniores masculinas. Os atletas foram agrupados, em função das suas posições em campo, em avançados (n = 24) e recuados (n = 22). Todos os atletas foram submetidos a uma avaliação antropométrica com determinação de estatura, massa corporal e nove pregas cutâneas. Quarenta submeteram-se, igualmente, a uma avaliação das suas capacidades físicas que consistiu na determinação da velocidade, aceleração e capacidade aeróbia máxima. A análise estatística foi realizada com recurso ao software IBM® SPSS® Statistics v.19, tendo sido considerado um valor de significância de 5%. RESULTADOS: Os avançados apresentaram um peso corporal médio de 96,02 kg (± 13,44) e 1,80 m (± 0,06) de estatura, contra os 76,84 kg (± 7,28) de peso médio e 1,73 m (± 0,06) de estatura dos recuados. Quanto à avaliação fisiológica, os recuados apresentaram globalmente melhores resultados. No teste dos 10m demoraram apenas 1,97 s (± 0,20) contra os 2,10 s (± 0,27) dos avançados. No teste de velocidade, os recuados demoraram, em média, 4,50 s (± 0,32), menos 0,36s que os avançados. A capacidade aeróbia máxima em função do peso verificada para os recuados (52,33 mlO2/min/kg ± 5,41) foi, igualmente, superior à dos avançados (46,60 mlO2/min/kg ± 5,64). DISCUSSÃO E CONCLUSÕES: Os avançados eram significativamente mais altos, mais pesados e apresentavam uma maior percentagem de gordura corporal que os recuados. Eram, também, mais lentos, e tinham uma menor capacidade aeróbia máxima em função das suas massas corporais. No entanto, apresentavam uma maior capacidade aeróbia máxima em valor absoluto e produziam um maior momento linear. As diferenças entre avançados e recuados foram ao encontro às da literatura e estão relacionadas com os distintos papéis desempenhados pelos atletas durante o jogo. Apesar das limitações inerentes a este estudo, acreditamos que este é pertinente e irá estimular o aprofundamento dos conhecimentos nesta área. Estudos semelhantes mas de maiores dimensões deverão ser realizados, no futuro, de forma a podermos avaliar e caracterizar mais fielmente o atleta de rugby português.

Background: Human immunodeficiency virus (HIV), the agent responsible for acquired immunodeficiency syndrome, remains a worldwide public health problem. Therefore, this study aimed to assess Portuguese healthcare students’ knowledge of HIV, identify risk behaviors for HIV transmission, and assess the frequency of HIV testing and its dissemination by general practitioners.Methods: A cross-sectional observational study was conducted using an anonymous questionnaire published online. The questionnaire was administered to Portuguese healthcare students who voluntarily agreed to participate in the study after clarifying its objectives and procedures.Results: Most students were aware of the three main HIV transmission routes; however, 66.3% were unaware of the level A recommendation for HIV screening in adolescents and adults. In addition, 59.6% of the students were never informed by their general practitioner about HIV screening tests or risk behaviors for HIV transmission. Of the sample, 78.9% had never been tested for HIV infection. Of the 74.6% of sexually active students, 82.0% had or had already had unprotected sex (without a condom). Men showed riskier sexual behaviors than women. None of the inquiries reported intravenous drug use, and most students (69.9%) never shared personal objects.Conclusion: General practitioners and awareness campaigns need to alert and disseminate HIV screening tests. Sexual health and risk behaviors should be addressed more frequently in schools to educate this population because prevention is the best strategy against HIV transmission/contraction.
