Abstract Introduction The literature presents few findings on the relationship between sleep quality and eating disorders indicators, especially in women fighters. Objective To compare the sleep quality among women who practice BJJ due to risk behaviors in eating disorders. Method Twenty-six women who practice Brazilian Jiu-Jitsu (BJJ) participated in this study. After completing the Free and Informed Consent Form, the participants answered the instruments separately (Eating Attitudes Test and Pittsburgh Sleep Quality Index). Data were analysed using the unpaired T-test and Pearson’s linear correlation. Results Twenty-six women who practice BJJ participated in the study. The first group had non-prevalence of eating disorders indicators (n = 14) while the second group had prevalence (n = 12). There was no correlation between sleep quality and eating disorders indicators in none of the groups. Similary, there was no statistical difference between the sleep quality of the two groups; however, both groups were poor sleepers. Discussion and conclusion Findings suggest that the prevalence of eating disorders indicators is high in women who practice BJJ, however, we did find a significant correlation between eating disorder indicators and sleep quality. Thus, as this is a nascent topic, further research is needed to better clarify this phenomenon.

Resumen Introducción En la literatura hay pocos hallazgos sobre la relación existente entre la calidad del sueño, y lo indicadores de trastornos alimenticios, especialmente en mujeres luchadoras. Objetivo Fue analizar la calidad del sueño con indicadores de riesgo de trastornos alimenticios en practicantes brasileñas de Jiu-Jitsu (BJJ). Método Veintiséis mujeres que practican BJJ participaron en este estudio. Después de completar un Formulario de Consentimiento Libre e Informado, las participantes respondieron por separado los instrumentos (Prueba de Actitudes Alimentarias e Índice de Calidad del Sueño de Pittsburgh). Los datos se analizaron con la prueba t no emparejada y la correlación lineal de Pearson. Resultados Participaron en el estudio 26 mujeres que practican BJJ, el primer grupo estuvo conformado por la no revalorización de los indicadores de trastornos alimentarios (n = 14) y el segundo grupo presentó prevalencia (n = 12). No se encontró correlación entre la calidad del sueño y los indicadores de trastornos de la alimentación en ninguno de los grupos. Tampoco hubo diferencia estadística entre la calidad del sueño de cada grupo, ambos grupos no dormían bien. Discusión y conclusión Los resultados señalan que la prevalencia de los indicadores de trastornos de la alimentación es elevada en las mujeres que practican BJJ; sin embargo, cuando se correlacionan los indicadores de trastornos de la alimentación con la calidad del sueño, no hay datos que indiquen la existencia de ninguna relación. Por lo tanto, dado que se trata de un tema reciente, es necesario seguir investigando para aclarar mejor este fenómeno.

Abstract Aim: Increasing age is associated with significant changes in athletes' performance; however, it is not yet known how increasing age could influence the performance of triathletes. In this sense, the present study aimed to investigate how the performance of two elite triathletes (HCK and AD), who participated and finished the Olympic Games in Sydney, Athens, Beijing, and London, could change over the years. Methods: This study reports two cases (male and female) with cross-sectional and retrospective characteristics that describe how the increasing age changes the performance of two elite triathletes who participated in four consecutive Olympics (2000, 2004, 2008, and 2012). Pearson correlation test was used to verify the correlation between the performance and age of the triathletes. A value of p < 0.05 was assumed to show statistical significance. Results: The results suggest that both triathletes showed impaired performance at the Summer Games in Athens in 2004. When the two athletes were analyzed together, positive correlations were observed between age and transition 1 (T1; swim-to-cycle) and transition 2 (T2; cycle-to-run). Also, a high correlation was found between T2 and age for HCK but not for AD. The results showed a significant correlation between increasing age and a reduction in running performance for HCK. Conclusion: Although the two triathletes improved overall time throughout the Olympic Games, this improvement did not correlate with age. Thus, the increasing age does not seem to impact these two athletes during the four Olympic events.

Abstract Introduction During the novel coronavirus disease (COVID-19) outbreak, social media exposure and the use of electronic devices have increased; still, these behaviors may cause adverse health effects. Objective This study assessed sleep quality, insomnia, mood, and psychological aspects among physically ( n = 46) and non-physically ( n = 53) active individuals during self-isolation throughout the COVID-19 pandemic and examined their association with smartphone addiction. Method A cross-sectional study was conducted among adult Brazilian citizens in self-isolation for at least 60 days; ninety-nine volunteers from different Brazilian regions were enrolled in the online survey. The Depression, Anxiety and Stress Scale-Short Form, the Pittsburgh Sleep Quality Index, the Insomnia Severity Index, the Brunel Mood Scale, and the Smartphone Addiction Scale-Short Version were used to assess the study outcomes. Results The results indicate moderate and large correlations of smartphone addiction with mood subscales, insomnia ( r = .52), anxiety ( r = .49), depression ( r = .49), and stress ( r = .49) symptoms. Also, it was observed that physically active participants were less addicted to smartphones than the non-physically active during self-isolation ( p < .01) and that the physically active ones had a better mood and lower anxiety ( p = .02), depression ( p < .01) and insomnia ( p < .01) levels. Discussion and conclusion These findings show the health implications of self-isolation and how essential it is to be physically active to avoid self-isolationʼs adverse psychological effects.

Resumen Introducción Durante el brote de la nueva enfermedad por coronavirus (COVID-19), la exposición a los medios sociales y el uso de dispositivos electrónicos han aumentado; sin embargo, estos comportamientos pueden causar efectos adversos en la salud. Objetivo Este estudio evaluó la calidad del sueño, el insomnio, el estado de ánimo y los aspectos psicológicos entre los individuos activos físicos ( n = 46) y no físicos ( n = 53) durante el autoaislamiento debido a la pandemia COVID-19 y examinó su asociación con la adicción a los teléfonos inteligentes. Método Se llevó a cabo un estudio transversal entre ciudadanos brasileños adultos en autoaislamiento durante al menos 60 días; noventa y nueve voluntarios de diferentes regiones brasileñas se inscribieron en la encuesta en línea. La Depression, Anxiety and Stress Scale-Short Form, the Pittsburgh Sleep Quality Index, the Insomnia Severity Index, the Brunel Mood Scale, and the Smartphone Addiction Scale-Short Version se utilizaron para evaluar los resultados del estudio. Resultados Los resultados indican correlaciones moderadas y mayores en la adicción a los teléfonos inteligentes con subescalas de humor, insomnio (r = .52), síntomas ansiedad ( r = .49), depresión ( r = .49) y estrés ( r = .49). Además, se observó que los participantes físicamente activos eran menos adictos a los teléfonos inteligentes que los no activos durante el autoaislamiento ( p = .01) y que los físicamente activos tenían un mejor estado de ánimo y menores niveles de ansiedad ( p = .02), depresión ( p = .01) e insomnio ( p = .01). Discusión y conclusión Estos hallazgos muestran las implicaciones para la salud del autoaislamiento y lo esencial que es ser físicamente activo para evitar los efectos psicológicos adversos del autoaislamiento.
