Introduction: Cerebral Palsy (CP) refers to a class of non-progressive neurological disorders that permanently affect individuals' sensory-motor abilities and typically appear in infancy or early childhood. The present study aimed to investigate the effect of linear and nonlinear training methods on the static balance ability of children with hemiplegic CP.
Methods: A total of 20 boys with hemiplegic CP, aged 7-12 years, were selected through convenience sampling and they were assigned into experimental and control groups. The Sharpened Romberg test was used to measure static balance scores. The linear and nonlinear training groups performed specific exercises for four weeks, three days a week, and one hour per session for each method. Multivariate Analysis of Covariance (MANCOVA) and univariate Analysis of Covariance (ANCOVA) were conducted at a significance level of P≤0.05.
Findings: The results showed a significant difference between the linear and nonlinear training methods in at least one of the static balance variables (p=0.001). Additionally, considering the higher scores of the nonlinear group, this training method resulted in better static balance scores (with eyes open and closed) compared to the linear method in children with hemiplegic CP.
Conclusion: Overall, the findings of this study emphasize the importance of the nonlinear training method in improving the static balance of children with hemiplegic CP and support the constraint-led approach

Introduction: Falling is one of the serious issues of old age that occurs due to many factors. This research aimed to compare static and dynamic balance, walking speed, spinal curvature, and central stability of elderly people with and without a history of falling.Methods: The current research was a causal-comparative research. 60 elderly women aged between 60 and 70 from Tabriz voluntarily participated in the research. The participants were assigned into two groups with and without a history of falling. The fall history of the participants was measured by the Fall Efficacy Scale. The static and dynamic balance were evaluated by Sharpened-Romberg and Timed Up and Go tests, respectively. Walking speed was measured with a 10-meter walk test, core stability was measured with McGill endurance tests, and spinal curvature was measured with a flexible ruler. Independent t-test was used to compare the mean variables in two groups.Results: The results showed a significant difference between the static and dynamic balance indices, lumbar spine curvature, walking speed, and core stability in the elderly with and without a history of falling. However, there was no significant difference between the curvature index of the lumbar spine in the elderly with and without a history of falling.Conclusion: According to the research results, it seems necessary to develop and improve the indices of balance, walking speed, and core stability in people with a history of falling.

Introduction: Upper crossed syndrome causes movement limitation and weakness in people's movement functions. This study aimed to compare physical literacy and upper extremity movement functions in girls with and without the upper crossed syndrome.Methods: The method of this research was descriptive and causal-comparative using field data collection. The statistical population of the research included two groups of healthy 10- to 12-year-old female students and also students with the upper crossed syndrome in Khalkhal City in the academic year of 2022-2023. Using G-power software, the statistical sample size was determined to be 60 people. These people were screened using a checkerboard and after quantitative height assessment, they were assigned to two Healthy (30 people) and the Upper Cross Syndrome (30 people) groups. Forward head angle and forward shoulder angle were measured using photography, kyphosis angle was measured using the Goniometer-pro app. The Canadian Assessment of Physical Literacy – version 2 (CAPL-2) questionnaire was used for the evaluation of physical literacy and Upper Quarter Y-Balance Test (UQYBT) was used to assess upper limb function. The Data were analyzed using an independent t-test in SPSS-26 software at the significant level of 0.05.Results The results showed that healthy girls were significantly in a better condition in all variables of physical literacy and upper limb function than girls with the upper crossed syndrome.Conclusion: According to the results of this research, it is suggested that coaches and sports and health professionals use the results of this study to develop the physical literacy and functions of students with the upper crossed syndrome.

Introduction: Sport is an important part of students' life. The social development of athletes could be different based on their gender and type of sport. The present study aimed to compare the social development of athletes (team and individual sports disciplines) and non-athlete students of Farhangian University.Methods: In a descriptive cross-sectional survey research, 2000 male and female students of Farhangian University of Mazandaran province were recruited as a statistical population. 300 students were selected using the cluster random sampling method. Witsman's Social Development Questionnaire (1990) was used as the research instrument. To analyze the data, a two-way analysis of variance and Tukey's post hoc test were used.Results: Based on the results of the two-way analysis of variance, significant results were found for the main effect of gender and group variables. However, the interaction effect of group and gender was not significant. The social development of female students was higher compared with male students. Based on the results of Tukey's post hoc test, athletes had significantly higher social development than non-athletes. Although the social development of athletes in individual sport discipline had a higher mean than the team athletes, the difference was not significant.Conclusion: Considering the higher social development of athletes compared with non-athletes and also, almost identical social development scores for both groups of athletes (team and individual sports disciplines), it is suggested that coaches foster a supportive environment by emphasizing the importance of equality of each athlete to provide the basis for social development among all people.

This study aimed at investigating the effect of blocked, incremental systematic and random contextual interferences on acquisition, retention and transfer of volleyball skills based on changes in a generalized motor program. In fact, this study was conducted to answer this question that whether regular increment of contextual interference level is more effective on learning volleyball service skill than blocked or random practice schedules. 30 students (mean age 23±4 yr, 3 groups and each 10 subjects) participated in this study. The groups were different in practices of the three services. Subjects performed simple, overhead and single arm skills from a distance (9 m from the volleyball net) with different practices. Each participant practiced 108 trials of each service, totally 324 trials during 9 sessions (each session 36 trials). The results indicated that incremental practice resulted in a better performance in retention and transfer tests than blocked and random practices (P˂0.05). In general, it was suggested that the practice should be scheduled so that it can start from low interference and gradually and systematically continues towards high interference in order to facilitate learning of several generalized motor skills.
