This study compares externalizing behavior disorders in overweight and normal-weight boys. The statistical population includes all the male students of elementary schools in Mashhad, who were selected using the cluster sampling method, six districts, and among the schools in this district, two boys' schools and a total of 222 students were selected as the research sample. Children's Behavior Checklist (CBCL) was used as a tool in this study. The results showed that, in general, there is a significant difference in externalizing behavior disorders between overweight and normal-weight boys (P<0.05), which is seen in conduct disorder and oppositional defiant disorder. In comparison, these two groups had no significant difference in attention deficit hyperactivity disorder (P<0.05). According to the results of the research, informing and changing the attitude of parents in preventing the occurrence of obesity and overweight and ultimately behavioral problems seems necessary, and since the deviation from normal weight is related to inappropriate and risky behaviors, early interventions and appropriate planning in this field is practical and necessary during the sensitive period of childhood.

Purpose: In this study, we investigated the effects of resistance training types on clinical and functional indices in older individuals with Osteosarcopenia. Method: In this Systematic Review study, a systematic searching strategy was used in information databases such as Pub Med, Web of Science, Scopus, Google Scholar, Cochrane, and Ambace, all of the studies were extracted by using specific keywords such as Strength exercise, Exercise training, Resistance exercise, Resistance training, Strength training, Physical activity, Osteosarcopenia, Aging, Older adult, Elderly which were published on 7th August 2023. After all preliminary screening, surveying of complete text, and assessment of critical studies, scrutinized articles were related to inclusion criteria. Finally, 17 papers were selected for this study. Results: According to the present study, Resistance training for Osteosarcopenia older individuals has an effective result to improve Osteosarcopenia risk factors, and older patients’ performance and clinical status. However, it has to be mentioned that it needs further study in the contexts of Resistance training and Osteosarcopenia syndrome in elderly adults. Conclusion: Resistance exercise training has markedly beneficial effects on elderly patients with Osteosarcopenia which improves Sarcopenia risk factors, and older patients’ performance, clinical status and function of elderly patients.

Purpose: Muscle flexibility is a component of physical fitness. Using traditional tools in muscle length evaluation tests creates challenges. Therefore, the use of smartphones and health-related software as an alternative method has become widespread. This study aimed to investigate smartphones' intra- and inter-rater reliability and validity for measuring hamstring muscle length. Method: In a blinded study design, two researchers measured hamstring flexibility through four types of tests on each of the 22 asymptomatic participants with a total of 44 lower limbs. The measurements were compared between the traditional goniometer method and the practical smartphone application method. The intraclass correlation coefficient (ICC) was used to evaluate the reliability of each smartphone measurement, and Bland-Altman analysis was used to check the measurement errors. The validity of the two methods was also investigated. Results: Intra- and inter-rater reliability (ICC≥0.8) were good to almost perfect. In intra-rater reliability, PSLR angle showed consistent imprecision; other tests were free of systematic error and measurement error. The inter-rater reliability revealed a constant error in the right leg's PKE angle. A good to excellent correlation (r = 0.817–0.699) was observed in all the measured values, indicating the two methods' validity. Conclusion: These findings support from intra- and inter-rater reliability and validity of both instruments when measuring hamstring muscle length.

During the Covid-19 pandemic, the use of online sports programs became popular. The purpose of this study was to investigate the effect of eight weeks of online body balance program on anxiety, depression, and aggression of children with attention deficit/hyperactivity disorder (ADHD). Body balance is a sport based on yoga, tai chi, and Pilates. The present study was a semi-experimental and applied type of study. The participants of the present study were 30 volunteer children with ADHD who were divided into two experimental (15 people) and control (15 people) groups by random assignment method. Aggression, depression, and anxiety variables were evaluated by Bass and Perry questionnaire, Maria Kvas children's depression questionnaire, and Revised Children's Manifest Anxiety Scale. The experimental group performed online body balance training for 8 weeks (3 sessions per week for 60 minutes) online, and the control group did their current activities. In order to investigate intra-group and inter-group differences, repeated measures ANOVA at the error level of 0.05 was used by SPSS software. The results showed there was significant difference in the average level of symptoms of depression, anxiety and aggression in the pre-test and post-test stages (P≤0.05), between the two control and experimental groups (P≤0.05) and the interaction effect of time and group (P≤0.05). The results of Tukey's test showed that there was a significant reduction of these symptoms between the two experimental and control groups in the variables of depression symptoms (-5.500), anxiety symptoms (-5.133) and aggression symptoms (-13.133). Based on the results of this research, eight weeks of body balance training reduced depression, aggression and anxiety symptoms in 7-9 year old children with attention deficit/hyperactivity disorder. Therefore, the improvement of mental disorders caused by this disease in children following the body balance exercise program emphasizes the importance of using this intervention method for children with ADHD.
