Background & Aim: This study aimed to investigate the effect of cardio kickboxing workouts on cardiorespiratory endurance, body composition, quality of life, and sleep quality of young male students living in dormitories. Methods: The research method was a quasi-experimental pretest-posttest design with a control group. To carry out this research, 20 male students in the Allameh Tabatabaei University dormitory were randomly selected and divided into two experimental and control groups, each group consisting of 10 people. In order to determine cardiorespiratory endurance, body composition, quality of life, and sleep quality, Queen''''''''s College Step Test (QCT), body fat percent using calipers, 36-Item Short-Form Health Survey questionnaire (SF-36), and Pittsburgh Sleep Quality Index (PSQI) were employed, respectively. Results: Based on the analysis of covariance of the data related to pretest and posttest of the two experimental and control groups, the data of four variables of fat percentage, cardiorespiratory endurance, quality of life, and sleep quality in the posttest were significantly different between the two groups that this statistical test was conducted at a significance level of P = 0.05. Conclusion: It appears that cardio kickboxing workouts have a positive impact on the health of male students in dormitories.

Background: The COVID-19 pandemic has resulted in global home confinement and quarantine, leading to the vaccination of societies worldwide. However, some elite athletes have negative views toward vaccination. Aim: This study aimed to compare the lifestyle of vaccinated versus unvaccinated international elite athletes during the COVID-19 pandemic. Materials and Methods: From March to October 2021, an online survey was conducted, including socio-individual information of athletes, the International Physical Activity Questionnaire (IPAQ), the Rapid Eating Assessment for Participants (REAP-S), and the Petersburg Sleep Quality Questionnaire (PSQI). A total of 581 elite athletes from 4 continents (Europe, Asia, Africa, and America) and different countries, aged 18-35 years, were voluntarily recruited. Data analysis was performed using U-Mann-Whitney and Wilcoxon signed-rank tests, with the level of significance set at alpha P <0.05. Results: The results indicated that there was a significant difference between the level of physical activity and eating behavior of vaccinated versus unvaccinated elite athletes ( P <0.001). However, no significant difference was found between the quality of sleep among vaccinated and unvaccinated elite athletes ( P =0.270). Conclusion: It was shown that, despite the unvaccinated status of some elite athletes (49.9%), their physical activity levels were higher than those of vaccinated elite athletes during the COVID-19 pandemic. Additionally, the eating behavior of vaccinated elite athletes was better than that of unvaccinated elite athletes during the COVID-19 pandemic, but there was no significant difference in the quality of sleep between the groups.

Purpose: Sleep and exercise influence each other through complex interactions. Sleep disorders incidence in athletes are high among several sports. Method: 24 CrossFit practitioners, of both genders, between the ages of 25 and 35, presenting difficulty in initiating sleep, with a total sleep time of less than 6 hours per night, were recruited into a double-blind, randomized, placebo-controlled trial that lasted 8 weeks. Participants received capsules containing 3 mg of melatonin + 1200 mg of GABA (gamma-Aminobutyric acid) or placebo at 10:00 pm daily. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), cortisol and testosterone levels were measured and total-body skeletal muscle mass (TBSMM) by Lee’s equation performed by two different examiners. Results: Group melatonin + GABA gained an average of 600g of TBSMM while the control group lost 200g (p = 0.295). Both groups improve PSQI score (p = 0.007). No difference was found in cortisol and testosterone level. Conclusions: Although there was a difference between groups about TBSMM, it wasn’t statistically significant. Further studies will be necessary to demonstrate evidence of increased TBSMM from better sleep quality, with a larger number of participants and a longer trial.

Introduction: Painful diabetic neuropathy is a major complication of chronic diabetes with a significant negative impact on the quality of sleep and quality of life in diabetic patients. This study was conducted to determine the single and combined effect of primary motor cortex (M1) and left Dorso lateral prefrontal cortex (L- DLPFC/ F3) anodic transcranial direct current stimulation (tDCS) in improving sleep quality and quality of life in type 2 diabetes patients with neuropathic pain. Method: The current study was a four-group double-blind randomized clinical trial. The statistical population consisted of all patients with type 2 diabetes aged 45 to 65 years, who were members of the Bonab Diabetes Association in 2022 and identified as having neuropathic pain by specialists. The research sample was 48 people selected through the purposeful sampling method and randomly assigned into three experimental groups and one sham control group. Patients in four groups received their respective interventions for 12 sessions, three times a week. The data collection was done using the Pittsburgh Sleep Quality Index (PSQI) and the 36-Item Short Form quality of life questionnaire (SF-36). Results: According to the findings, only the stimulation of M1 and F3 areas was effective in improving the sleep quality of diabetic patients. In terms of increasing quality of life, the effect of combined treatment (stimulation of both M1 and F3 areas) was significantly higher than the F3 area stimulation and sham stimulation groups. Also, the observed effect remained stable until the 3-month follow-up stage. Conclusion: According to the results of this research, neuropsychological rehabilitation through electrical stimulation of the M1 and F3 areas of the brain was supported to improve the sleep quality and the quality of life of diabetic neuropathy patients.

Purpose: The world is getting old. Alzheimer's disease is a progressive disease, which in case of no intervention, this ratio reaches 4 more advanced stages in people over 85 years old. Some methods have shown that they can be effective in preventing and slowing down the course of the disease. The purpose of this study was to investigate the role of aerobic exercise program on the quality and some physiological parameters related to sleep in the elderly with Alzheimer's disease. Method: 22 elderly people with Alzheimer's disease were randomly divided into two groups of 11 people: aerobic exercise and control. The subjects in the aerobic training group practiced three sessions every week for twelve weeks and each session lasted for 45 minutes. The sleep quality of the subjects was evaluated by the Pittsburgh Sleep Quality Questionnaire (PSQI). Physiological variables related to sleep (TG, TC, LDL, HDL) were also measured by blood sampling before and after twelve weeks of aerobic exercise Results: The results showed that the sleep quality of the subjects improved by 31% in the Pied Heroi group, which was statistically significant. In addition, there was a significant improvement in the changes of TG (p=0.034), TC (p=0.017), LDL (p=0.006), and HDL (p=0.016) in the aerobic training group. The results of the independent t test also showed that there was a significant difference in sleep quality between the aerobic training and control groups. However, no relationship was observed between changes in sleep quality and changes in physiological variables related to sleep. Conclusion: It can be concluded that twelve weeks of aerobic exercise improves sleep quality along with some physiological parameters related to sleep in the elderly with Alzheimer's disease and will be useful as a way to treat sleep problems in the elderly.

Purpose: Sleep quality decreases with age, and as a result, sleep complaints are common in the elderly, especially for inactive people with Alzheimer's disease. Therefore, the aim of this study was to investigate the relationship between respiratory indices and sleep quality in active and inactive elderly women with Alzheimer's disease. Method: In this research, 24 elderly women with Alzheimer's disease (with an average age of 72.3±7.25 years, height 158.23±6.12 cm and weight 70.23±8.12 kg) voluntarily and after obtaining consent, they participated in two active (12 people) and inactive (12 people) groups. Respiratory indices were measured using a Micro Lab Spirometer. The Pittsburgh questionnaire was used to check sleep quality. Independent t-tests and Pearson's correlation coefficient were used to analyze the data. Results: The average score of sleep quality in the active group was significantly lower than the inactive group (p=0.013). Also, the parameters of expiratory volume with pressure in the first second (p=0.046), maximum voluntary ventilation (p=0.021), forced vital capacity (p=0.033), strong expiratory flow 25 to 75% in the active group was significantly higher than the inactive group. Conclusions: According to the results, it seems that sports activity can be an effective factor in improving the quality of sleep and the functioning of the respiratory system in patients with inactive Alzheimer's disease.

This study aimed to explore the influence of teachers' sleep quality and self-efficacy on burnout in Iranshahr City. The statistical population for this study comprised all secondary high school teachers in Iranshahr city during the academic year 2023 – 2024. The sample consisted of 118 teachers who were chosen using the convenience sampling method. To gather the data, the job burnout questionnaires developed by Maslach, Jackson, and Leiter (1986), the Petersburg sleep quality questionnaire (1989), and the teacher self-efficacy questionnaire created by Schanen, Moran, and Woolfolk (2001) were utilized. To analyze the data, Pearson correlation and multiple regression were conducted, with all analyses carried out using SPSS software version 24. The results of the Pearson correlation coefficient indicated that emotional exhaustion and depersonalization had a negative correlation with comprehensive involvement, educational strategies, and class management (p<.01), while personal accomplishment showed a notable positive correlation with comprehensive involvement, educational strategies, class management, and sleep quality (p<.01). The overall model accounted for 24.7% of the variance in emotional exhaustion and 11% of the variance in depersonalization. Thorough involvement accounted for 14.5% of the variance in personal accomplishment, while sleep quality explained 9% of the variance in personal accomplishment.

Objective: This study aimed to examine the impact of rumination on both cognitive and sports performance, with sleep quality serving as a mediating factor.Methods: The research was practical in purpose and employed a structural equation correlation design, conducted in a field setting. The statistical population consisted of all student athletes who participated in the table tennis tournaments in Khorasan in 2022, totaling 97 individuals. Sampling was performed using a census method, with 80 participants consenting to engage in the study. Data were collected using the rumination questionnaires developed by Nolen-Hoeksema and Morrow (1991), a sports performance scale by Charbonneau et al. (2001), a cognitive performance assessment by Folstein et al. (1975), and the Pittsburgh Sleep Quality Index (1989). For data analysis, Pearson's correlation coefficient and path analysis modeling were utilized. Results: The findings indicated that rumination has a direct influence on both cognitive and sports performance (P=0.01). Furthermore, rumination significantly affects these performances indirectly through the mediation of sleep quality (P=0.01) among student athletes. Conclusion: Based on the results of this study, rumination is correlated with cognitive and sports performance both directly and indirectly via sleep quality. It is recommended to engage a sports psychologist to conduct educational workshops on rumination management and to monitor and regulate the sleep patterns of student athletes.

This study aimed to examine the relationships between sleep quality, body image dissatisfaction, and impulsiveness in adolescent girls with mild physical disabilities. This cross-sectional study included 186 adolescent girls with mild physical disabilities. Participants were recruited from rehabilitation centers and special schools. Impulsiveness was measured using the Barratt Impulsiveness Scale (BIS-11), sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI), and body image dissatisfaction was evaluated using the Body Shape Questionnaire (BSQ). Pearson correlation coefficients were calculated to examine the relationships between the variables. A linear regression analysis was performed to determine the predictive value of sleep quality and body image dissatisfaction on impulsiveness, using SPSS version 27. The mean score for impulsiveness was 55.28 (SD = 10.45), sleep quality was 12.67 (SD = 3.98), and body image dissatisfaction was 87.34 (SD = 15.29). Pearson correlation analysis showed significant positive correlations between impulsiveness and sleep quality (r = 0.45, p < .001), and between impulsiveness and body image dissatisfaction (r = 0.52, p < .001). The regression model indicated that both sleep quality (B = 0.92, p < .001) and body image dissatisfaction (B = 0.25, p < .001) significantly predicted impulsiveness, explaining 37% of the variance (R² = 0.37, F(2, 183) = 53.68, p < .001). Poor sleep quality and high body image dissatisfaction are significant predictors of impulsiveness in adolescent girls with mild physical disabilities. Interventions aimed at improving sleep quality and promoting positive body image may help reduce impulsiveness and enhance overall well-being in this population.

The primary objective of this study was to evaluate the effectiveness of Reality Therapy in improving temperament and sleep quality among adolescents with learning disorders. This randomized controlled trial included 30 adolescents, aged 12 to 18, diagnosed with learning disorders. Participants were randomly assigned to either the intervention group (15 participants) or the control group (15 participants). The intervention group underwent twelve 60-minute sessions of Reality Therapy over a two-month period, while the control group received no therapeutic intervention. Temperament and sleep quality were assessed using the Revised Dimensions of Temperament Survey (DOTS-R) and the Pittsburgh Sleep Quality Index (PSQI), respectively, at three time points: pre-intervention, post-intervention, and two-month follow-up. Data were analyzed using analysis of variance (ANOVA) with repeated measurements and the Bonferroni post-hoc test, with SPSS-27 software. The results indicated significant improvements in both temperament and sleep quality in the intervention group compared to the control group. These improvements were sustained at the two-month follow-up. Specifically, the intervention group showed marked improvements in emotional regulation and sleep patterns, highlighting the efficacy of Reality Therapy in addressing these critical aspects of adolescent health. Assumptions for ANOVA were confirmed, ensuring the robustness of the findings. Reality Therapy significantly improves temperament and sleep quality in adolescents with learning disorders, with effects lasting beyond the intervention period. This study supports the use of Reality Therapy as a viable intervention for improving emotional and sleep-related outcomes in this population. Further research with larger sample sizes and extended follow-up periods is recommended to confirm these findings and explore additional benefits.

Objective: The current study investigated the impact of COVID-19 on lifestyle and cognitive function, overweight, and sleep quality among children and adolescents in Abyek city during the quarantine period. Method: In this study, a descriptive-analytical research method was used, and a combination of stratified and multi-stage cluster sampling was employed for sampling. The study population included 2152 students (1184 girls and 968 boys) from elementary and middle school levels in Abyek city. Data were collected using electronic questionnaires, which were a compilation of the Food Frequency Questionnaire (FFQ localized in 2009), Beck Physical Activity (Beck et al., 1982), Cognitive Function (Nejati et al., 2013), and Pittsburgh Sleep Quality Index, sent online to the students. Subsequently, the collected data were analyzed and examined. Findings: This study found no significant correlation between students' BMI and their dietary habits or physical activity level (p > 0.001, rs = 0.45) as well as between physical activity level and dietary habits or cognitive performance. However, there was a significant positive correlation between sleep quality and physical activity level scores (p < 0.011, rs = 0.26), and between cognitive performance and sleep quality (p < 0.001, rs = 0.49). Regarding gender differences, male students had a higher Body Mass Index (BMI) and physical activity level compared to female students (p = 0.018 and p < 0.001, respectively), and there was a significant difference in dietary habits between boys and girls (p = 0.006). No significant difference was observed between boys and girls in terms of sleep quality and cognitive performance (p = 0.180 and p = 0.693, respectively). Conclusion: According to the study, it appears that changes in diet, physical activity, and sleep quality affect students' cognitive performance during the COVID-19 quarantine. These results indicate that planning to maintain and control physical activity, nutrition, and sleep quality during quarantine is essential to mitigate potential negative effects on students' cognitive performance.

Objective: The present study aimed to predict sleep quality based on migraine headaches and rumination in women with panic attacks. Methods: This applied and descriptive-correlational study included a sample of women who visited psychological clinics in the city of Isfahan. Using convenience sampling, 210 participants were selected. Data were collected using the Pittsburgh Sleep Quality Index (1989), Ahvaz Migraine Headache Symptoms Questionnaire (1997), and the Rumination-Reflection Questionnaire by Trapnell and Campbell (1999). For data analysis, simultaneous multiple regression was performed using SPSS version 21. Findings: The findings indicated that migraine headaches and rumination could explain 30.5% of the variance in sleep quality among patients with panic attacks. Specifically, with each standard deviation increase in migraine headache and rumination scores, there was a corresponding increase of 0.532 and 0.371 standard deviations in sleep quality scores, respectively (P < 0.01). Conclusion: Based on the results, migraine headaches and rumination can predict sleep quality in patients with panic attacks.
