Background: Children's motor skills are inversely related to sedentary screen time. COVID-19-lockdown during the pandemic has caused a further increasing on screening time. Aim: The current research aims at investigating the impact of Stickygym games on motor development of children. Materials and Methods: Twenty-eight eligible subjects (4-6 years old) were chosen and randomly grouped into control group (n=13) and experimental group (n=15). Using TGMD-2 test, gross motor development was measured. The experimental group performed online Stickygym games for 8 weeks. Stickygym kit includes Hook & Loop strips, with two linear polyester strips being easily but firmly attached together. Trained instructors performed online training sessions. In the end, TGMD-2 test was conducted again in person. Data analysis was done using Shapiro-Wilk, Levene and the analysis of covariance tests were with the significance level of 0.05 in SPSS 24. Results : Some locomotion skills were significantly improved by Stickygym games: bound ( P =0.005), galloping ( P =0.012), and running ( P =0.003), as well as object control skills: overhand throw ( P =0.004), underhand roll ( P =0.01), and striking a stationary ball ( P =0.021). Conclusion : This play kit can be utilized by pre-school educators and parents for improving object control and locomotion skills in preschool children.

Background: flatfoot is a common deformity characterized by the midfoot arch collapses during walking. As the midfoot is responsible for shock absorption, persons with flatfoot experience increased risk of injuries Aim: to the purpose of this study was to compare some motor-physical factors, lower extremity performance and stability index in male adolescents 10-12 having structural flat foot with and without insole. Materials and Methods: Subjects who utilized medical insoles for four to six months were selected in access from technical orthopedic in Karaj. After parents got aware of the purpose and conditions participating in research, their height and weight were measured. In the first day, they were assessed by motor-physical factors test (agility, speed, endurance), lower extremity performance (one-leg jump, cross jump, maximum distance access, walking six meters) and stability index wearing insole and on the next day without wearing insole. To analyze data, paired t-test was utilized. Wilcoxson was used respectively for parametric and non-parametric data. Results : According to the paired t-test a significant difference was observed in the 6-meter timed test. Mean difference was slower in wearing insole compared to not wearing insole. Moreover, stability index results showed more stability when not wearing insole which eyes were closed to significant. Conclusion: According to the results, wearing insole in individuals with flat foot, could slow down the walking speed. However, wearing insole may improve stability index when visual input is not in access.

Background: Since the outbreak of COVID-19 virus and the rise in concerns, researchers have been investigating risk factors of this disease. One of the factors affecting the hospitalization of influenza patients is high BMI. Due to the relation between COVID-19 disease and influenza. Aim : the purpose of this study was to investigate the effect of BMI on the infection and severity of COVID-19 patients. Materials and Methods: BMI of 126 men was calculated and three groups of "appropriate weight", "overweight" and "obese" were identified. Then, the prevalence and severity of their disease were recorded. For data analysis, chi2 test was used in SPSS 26 software at a significance level of P = 0.05. Results: Prevalence of COVID-19 infection in the group with “appropriate weight”, ”overweight” and “fat” were 56%, 61% and 58%, respectively. Mild infection was reported in the three groups, 27%, 27% and 26%, respectively; Moderate infection was 22%, 26% and 26%, respectively; and severe infection was 7%, 8% and 5%, respectively. Therefore, there was no significant difference between their infection and the severity of infection in groups ( P ˃.05). Conclusion: Obesity has negative effect on the body's immune response and lung function. The hospitalization rate for influenza is higher in this group. But in infection of COVID-19 and severity of this disease, no significant difference was observed between men with different BMI. However, due to the relation between obesity, cardiovascular disease, diabetes, and the vulnerability of these patients to the COVID-19 virus, serious attention is necessary to prevent these individuals from COVID-19.

Background: In addiction field, there is more attention on men than women, while women are more vulnerable to addiction. Because of the importance of women in the family foundation, we decided to investigate this subject. Purpose: This study aims at the effect of 8-weeks of combined training with methadone on cardiovascular inflammatory markers fibrinogen and CRP on addicted women. Method: This study accomplished as a semi-experimental research. 24 addicted women were randomly selected as samples from Zahedan Mohabbat addiction Camp that divided in two groups of methadone (N= 11) and methadone/ exercise (N= 13) by the same variables such as age, BMI, type and duration of drug withdrawal. The protocol of combined exercise was included of aerobic added to strength training; also methadone was taken according to the camp instructions, too. Blood sampling, pre and post 8 weeks exercise were directly collected from anterior veins of samples and the levels of plasma fibrinogen and CRP were measured in lab. To compares of the pre and post tests means for each group as well as both groups, paired and independent t-test via SPSS software version 24 were used, respectively. Statistical significant level was considered PResults: The results showed that CRP values in both groups decreased significantly (methadone: p <0.05, T=-2.21 and methadone/ exercise p <0.05, T=-2.63). Also, plasma fibrinogen values in both groups increased significantly (methadone: p <0.05, T=5.03 and methadone/ exercise: p <0.05, T=4.21). Also, there were no significant difference between post-test’s levels of CRP and fibrinogen between methods (P>0.05). Conclusions: It has suggested that the method of methadone/ exercise might be used as such as methadone method by the same results on plasma fibrinogen levels and CRP for withdrawal addiction women.
