Ser lutador traz mais prestígio?

Pesquisadores franceses investigaram se o envolvimento de homens com a luta trazia maior prestígio, maior acesso a companheiras e maior número de filhos. A resposta foi sim, embora as mulheres da etnia investigada tenham apontado o fato de ser lutador como um fator pouco relevante em suas escolhas.
Apesar da relação entre esses farores ser polêmica, vale a pena ler o texto inteiro (para aqueles que tiverem o acesso ao artigo na íntegra).
Eu recomendo, pois o texto está bem escrito.

Ritual fights are widespread across human populations. However, the evolutionary advantage associated with this behaviour is unclear because these fights rarely provide direct benefits such as territory, resources or mates. Here, the reproductive success of men competing in a traditional ritual fight, Sereer wrestling, was investigated for the first time. Involvement in wrestling had a significant positive effect on men's number of offspring and a marginally significant effect on polygyny, controlling for age, body condition and socio-economic status. These positive effects suggest that being involved in wrestling competition provides prestige, facilitating access to mates and thereby increasing fecundity. However, when women were interviewed on their preference concerning qualities of potential mates, the quality 'being involved in wrestling competition' was poorly ranked. This discrepancy may arise either from deceptive reports or from discordance between parents and daughters in the choice of a husband.

BACKGROUND: Standardized assessment of sports injuries provides important epidemiological information and also directions for injury prevention. PURPOSE: To analyze the frequency, characteristics, and causes of injuries incurred during the Summer Olympic Games 2008. STUDY DESIGN: Descriptive epidemiology study. METHODS: The chief physicians and/or chief medical officers of the national teams were asked to report daily all injuries newly incurred during the Olympic Games on a standardized injury report form. In addition, injuries were reported daily by the physicians at the medical stations at the different Olympic venues and at the polyclinic in the Olympic Village. RESULTS: Physicians and/or therapists of 92 national teams covering 88% of the 10977 registered athletes took part in the study. In total, 1055 injuries were reported, resulting in an incidence of 96.1 injuries per 1000 registered athletes. Half of the injuries (49.6%) were expected to prevent the athlete from participating in competition or training. The most prevalent diagnoses were ankle sprains and thigh strains. The majority (72.5%) of injuries were incurred in competition. One third of the injuries were caused by contact with another athlete, followed by overuse (22%) and noncontact incidences (20%). Injuries were reported from all sports, but their incidence and characteristics varied substantially. In relation to the number of registered athletes, the risk of incurring an injury was highest in soccer, taekwondo, hockey, handball, weightlifting, and boxing (all >/=15% of the athletes) and lowest for sailing, canoeing/kayaking, rowing, synchronized swimming, diving, fencing, and swimming. CONCLUSION: The data indicate that the injury surveillance system covered almost all of the participating athletes, and the results highlight areas of high risk for sport injury such as the in-competition period, the ankle and thigh, and specific sports. The identification of these factors should stimulate future research and subsequent policy change to prevent injury in elite athletes.
