RESUMO
Background: Contemporary lifestyles trigger changes in the sleep quality in youngsters causing effects on mental health, lifestyles and quality of life. Aim: To investigate health, lifestyles and quality of life indicators associated with sleep quality in university students. Material and Methods: The Sleep Self-Report (SSR), screen time, The International Physical Activity Questionnaire (PAQ) and the SF-36 survey about health-related quality of life were responded by 621 university students through an online platform. In addition, sociodemographic variables, health status and lifestyles were evaluated. Results: University students with poor sleep quality reported being significatively more sedentary, having less physical activity, and having a lower quality of life. Additionally, university students who consumed alcohol three or more times per week (Odds ratio (OR)= 6.2), spent more than six hours per day sitting (OR = 1.9), slept less than 6 hours per day (OR = 2.2), had more body pain (OR = 2.8) and had less social function (OR = 1.8) were more likely to have a poor quality of sleep. Conclusions: Quality of life and lifestyles risk factors such as drinking alcohol three or more times per week, having sedentary behaviors for more than six hours per day, having less than six hours of sleep per day, suffering high levels of body pain and low social function are associated with poor sleep quality in university students.

PURPOSE OF REVIEW: To verify the effects of sodium bicarbonate (NaHCO3) supplementation on biochemical and physical measurements of combat sports athletes. RECENT FINDINGS: A systematic review of articles indexed in three databases (PubMed, CAPES journal, and Google Scholar) was carried out until October 2020, using descriptors related to NaHCO3 supplementation in combat sports. First, 38 articles were identified. Next, eight articles were selected through the inclusion and exclusion criteria. The methodological quality of the articles was assessed using the Physiotherapy Evidence Database (PEDro) scale (8 and 9 points). Blood lactate, rating of perceived exertion, Special Judo Fitness Test, Dummy throw, and mean and peak powers for Wingate were evaluated. Random effects meta-analysis was used, the effect size was adjusted by corrected Hedges' g, and the heterogeneity is explored by I2. The results were obtained through weighted average and 95% CI, and the significance limit was set as p < 0.05. NaHCO3 supplementation had a significant effect on increasing blood lactate (p = 0.006) of the athletes studied. However, the performance measures (rating of perceived exertion, power, and specific performance) did not show a significant difference (p Ë 0.05). In conclusion, NaHCO3 supplementation causes a significant increase in blood lactate, indicating an ergogenic effect on buffer, which can delay the onset of fatigue and contribute to the performance of combat sports athletes. New experimental studies need to be published that assess the effect of acute and chronic NaHCO3 supplementation in specific combat sports tests and in women.
