The article aims to summarize the literature about the profile of risk of orthorexia in athletes using the ORTO-15 questionnaire. The search was performed at PubMed, Embase, Web of Science, and Sport Discus databases, using the terms “orthorexia” AND “athletes” with the respective entry terms. A multistage process of selection followed the PRISMA 2020 recommendation. A total of 688 articles were identified, and six studies were available for the final process. The prevalence of risk for orthorexia was assessed by the articles by the ORTO-15 questionnaire and ranged between 38 and 35 points. The comparison between male and female athletes and, athletes and non-athletes was not significant in the six articles. In conclusion, the review highlights that athletes from different sports, included in the review, do not present a risk of orthorexia nervosa considering the cutoff of 40 points, but not 35 points. Also, athletes present the same orthorexic behavior compared to non-athletes, demonstrating that orthorexia is an issue that needs to be considered in the general population. Moreover, a special focus should be given on the ORTO-15 questionnaire, about the sensitivity to diagnose the prevalence of orthorexia, especially in athletes.

Resumo Contexto Pacientes com úlceras venosas reportam múltiplas comorbidades e são mais propensos a ser fisicamente inativos. A sarcopenia e a fragilidade aumentam a vulnerabilidade de um indivíduo para maior dependência e/ou morte. Objetivos Verificar presença da sarcopenia e fragilidade em pacientes portadores de úlceras venosas crônicas. Métodos Estudo observacional e transversal, realizado com 9 pacientes com idade média de 67,4 ± 8,42 anos e portadores de úlcera venosa nos membros inferiores classificadas no Consenso Internacional de Doenças Venosas Crônicas (CEAP) em estágio 6. Para identificação e classificação da sarcopenia, foi avaliada a força (dinamometria manual), a velocidade da marcha (teste de caminhada de 10 metros) e a massa muscular (circunferência da panturrilha). Para triagem de fragilidade, foram utilizados os critérios de Fried: perda de peso não intencional, fadiga, redução da força e da velocidade da caminhada e baixa atividade física. Resultados O fenótipo de fragilidade foi mais frequente (n = 9; 100%) em relação à sarcopenia (n = 1; 11,1%). Entre os critérios de Fried, os mais frequentes foram a exaustão (n = 9; 100%), seguida pela baixa atividade física (n = 8; 88,8%) e fraqueza muscular (n = 5; 55%). Por fim, o critério menos frequente foi a diminuição da velocidade da marcha (n = 2; 22,2%). No diagnóstico de sarcopenia, foi observada redução da força associada à redução da massa muscular (n = 1; 11,1%). Conclusões Pacientes com úlceras venosas crônicas apresentam condição de fragilidade ou pré-fragilidade, enquanto a condição de sarcopenia foi pouco frequente.

This study aimed to examine the effects of Simple Reaction Time (SRT), MaximalOxygen Uptake ( V ? V ? O2max) and Maximal Anaerobic Power (Pmax) on the performance of category A recreational adult orienteers of both sexes. Sixteen subjects (8 men and 8 women; age: 30 ± 4 and 27 ± 5 years; body mass 78.8 ± 5.9 and 69.2 ± 10.4 kg; SRT: 1.391 ± 0.19 and 1.317 ± 0.25 ms; V ? V ? O2max: 67.4 ± 3.22 and 48.5 ± 8.28 ml.kg-1.min-1; Pmax: 675.0 ± 149.6 and 458.4 ± 88.62 W), were submitted to three evaluation sessions: sample characterization (1st session); SRT - Reaction Time Task v.2.0, V ? V ? O2max, and Pmax - Running Anaerobic Sprint Test (2nd session); official Orienteering test (3rd session). Results of comparison (Student’s T-test) and relation (Pearson Product-Moment Correlation and Multiple Linear Regression) tests showed significant relationships between independent variables and performance. Pmax presented strong predictive power in the male group (41%), followed by SRT (32%) and V ? V ? O2max (27%). In the female group, SRT was the most predictive variable (54%), followed by V ? V ? O2max (32%) and Pmax (12%). These findings indicated that SRT, V ? V ? O2max, and Pmax are variables predictive of performance in recreational category A orienteers. Specifically in recreational orienteers with high cardiorespiratory capacities, Pmax seems to be the mainpredictor variable. Conversely, SRT becomes the variable with the greatest predictive power.
