This study compared team and individual motor activity games on the development of social skills and executive functioning of students.

This quasi-experimental study used a pretest-posttest design with a control group. The statistical population of the research consisted of all male students (256 subjects) of primary school in municipal Zone 4 of Tehran. The sample in the present study was estimated to be 30 students in 3 groups using G*POWER to achieve a test power of 0.8 and an effect size of 0.80. Cluster sampling method was used to select students. In the first stage, 5 schools, 1 class from each school, and 6 students from each class were randomly selected as samples. They were randomly and equally divided into 3 groups of team games, individual games, and the control group. The Matson Evaluation of Social Skills with Youngsters-II (1983) was used to measure social skills, and The Barkley Deficits in Executive Functioning Scale—Children and Adolescents (BDEFS-CA) (2012) was used for executive functioning. In the present study, the designed experiment consisted of sixteen 60-min sessions (2 sessions per week); two types of experimental protocols including individual games and team games and also control conditions were used. Individual exercises included ten male students wherein each student performed the exercises with a coach. Team exercises included ten male students in the form of two teams who performed exercises as various activities and games.

By examining the results of difference in the means of the two intervention groups (team and individual exercises) and control group, it was found that in the sub-components of appropriate social skills, aggressiveness, and impulsive behaviors, the individual exercises group was more effective compared to the team exercises group (P<0.05). In the sub-components of non-social behaviors, superiority, high self-confidence, relationship with peers, and total social skills, the team exercises group was more effective compared to the individual exercises group (P<0.05). Besides, by examining the results of the difference in the means of the two intervention groups (team and individual exercises) and control group, it was found that the individual exercises group was more effective in the sub-components of self-organization, problem-solving, and self-motivation compared to the team exercises group (P<0.001). Yet, in the sub-component of self-management of time, self-control/inhibition, self-motivation, and total executive functioning, the team exercises group was more effective compared to the individual exercises group (P<0.001).

Based on the results of the research, it can be concluded that both team and individual exercises lead to the promotion of social skills and executive functioning in students. Moreover, compared to individual exercises, team exercises are superior in enhancing students’ social skills and executive functioning.

Low back pain is one of the most common reports among people in society. The present study aimed to determine the effect of a course of “Barre au sol” exercise on pain, endurance, and movement patterns of men with non-specific chronic back pain.

Totally, 26 middle-aged men (30-45 years old) with non specificchronic back pain were purposefully selected and randomly divided into two experimental (n=13) and control (n=13) groups. The “Functional Movement Screen” (FMS) and “Nine Test Screening Battery” (9TSB), McGill Torso Endurance Tests, and visual pain scale (VAS) were used to check movement patterns, trunk endurance, and pain levels of participants, respectively. Both groups received common physiotherapy treatments (posture correction in different postures and physiotherapy modalities). In addition to these treatments, the experimental group participated in the  Barre au sol training program for eight weeks (three sessions per week and one hour per session). In the present study, the covariance test was used for between-group comparison and the correlated t-test was used for within-group comparison. 

The results of the study show the effect of exercise program on reducing pain (p≤0.01), improving trunk endurance (p≤0.01), FMS screening tests (p≤0.01) and 9TSB (p≤0.01).

Barre au sol exercises have been effective in reducing pain, improving trunk endurance, and functional screening tests in patients with non-specific chronic back pain. Based on this, it is recommended to use this exercise program to reduce pain and generally improve performance for these patients.

Chronic back pain is a common disease among men. The aim of this study was to investigate the effect of a Graston massage session on pain and range of motion of the lumbar and hip regions in men with chronic low back pain.

The present study was an experimental study with a pre-test-post-test design. Participants in this study were 56 men with chronic low back pain who were selected by purposive sampling method and randomly assigned to experimental (n = 28) and control (n = 28) groups. In this study, pain with VAS visual index and range of motion were evaluated with inclinometer along with Android smartphone application. In the experimental group, massage with Greston instrument was performed for one session for 20 minutes. The control group did not receive any intervention in this study. In order to test the research hypotheses under normal conditions, analysis of covariance (between groups) and correlated t (within groups) were used

The results of this study showed that applying a Graston massage session on constant pain during movement and range of motion of men with chronic low back pain was effective (P ≤ 0.05).

Due to the effect of Craston massage on back pain and range of motion of the joints, coaches and sports physicians are recommended to use this type of intervention to prevent injuries and treatment.

Low back pain causes movement and occupational restrictions in women. The aim of this study was to compare women with and without low back pain and its relationship with body type, muscle percentage and fat.

The statistical population consisted of women with low back pain (28 people, 30 to 60 years old) were randomly selected and 28 people were selected as healthy or controls. In this study, tape meter, caliper, colis, Heath Carter test, physical fitness software, body composition measuring device, camera and corrective movements software were used.

Among the variables of body mass index, in all skinfolds (triceps, supralliac, subscapular and calf), arm condyle diameter, lumbar angle, percentage of fat and muscle, fat and muscle weight, as well as in ectomorphic somatotypes and there is a significant difference in endomorphs. The predominant type of women with low back pain is ectomorphic-endomorph type. There was no significant relationship between endomorphic and mesomorphic body type with muscle and fat percentage (except for fat percentage in the low back pain group).

In women with low back pain and obesity, being overweight leads to changes in body type and abnormalities in the trunk and spine. Therefore, experts in the field of physical education and corrective movements are recommended to provide exercises to correct lordosis and kyphosis. On the other hand, by identifying these people, it is possible to prevent abnormalities, injuries, and excessive medical expenses.

This study aimed at examining the effect of manipulating the length of static eye training on learning an inhibitory skill in children with developmental coordination disorder.

A quasi-experimental method with a pre-test and a post-test design was utilized during a 14-day follow-up period. The statistical population of the study were the 6-year-old girls with developmental coordination disorder in the kindergarten of Isfahan University. Using tests for assessing children's motor skills - the second version, 45 children with developmental coordination disorders were selected. Based on the pre-test scores (performance), participants were divided into three groups of 15: basic resident eye training, short-term resident eye training, and long-term resident eye training. In the pre-test, participants received 10 attempts at bean bags. The acquisition phase was performed in 18 sessions, with 10 attempts per session. At the end of the last training session, in the post-test and in two weeks of non-training in the memorial phase, the participants received 10 attempts at bean bags. At each stage, visual information was recorded by an eye tracking device and the accuracy of the throw was recorded by the researcher. Data were analyzed using analysis of variance with repeated measures.

The results indicated that basic resident eye exercises, short-term resident eye exercises, and long-term resident eye exercises had a significant effect on receiving skills and duration of resident eye period (P < 0.05). Also, long-term resident eye exercises had a higher effect size compared to short-term and basic resident eye exercises.

In general, the results of the study emphasized the importance of a longer resident eye period on learning inhibitory skills, which confirms.
