This study aimed to investigate the effectiveness of the tactical games model on self-efficacy, physical activity enjoyment, and learning of badminton long serve in adolescent female students.

The current research method was a quasi-experimental type with a pre-test and post-test research design that included two experimental and control groups. Thirty female students aged 9 to 12 years old voluntarily participated in the research. After being homogeneous according to anthropometric features, they were randomly assigned to two tactical games model (n=15) and traditional training (n=15) groups. The training program included a badminton training program that was conducted for eight weeks and three 60-minute sessions per week using two traditional and tactical games methods. The tools used in this study included the Physical Activity Enjoyment Scale, the General Self-Efficacy Scale, and the badminton long serve test.

The results of the analysis of covariance and independent samples t-test showed that the tactical games model group had a significant increase in self-efficacy, physical activity enjoyment, and badminton long serve scores compared with the traditional training group.

Overall, these findings suggest that a training course with a tactical games model has advantages in some psychological variables and motor skills learning of badminton long serve compared with the traditional method.

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.

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.

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.

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.

The Purpose of the current study was to examine the effect of a progressive relaxation training period on muscle efficiency and performance of archery athletes. ‎

In this semi-experimental study, which was conducted with a pre-test-post-test design with a control group, 40 male archery athletes were randomly selected and placed in two groups of relaxation and control exercises. In the pre-test stage, the participants made 9 archery throws, during which the electrical activity was recorded using an electromyography device. According to the method proposed in the methodology of the research, the training phase of progressive relaxation was done in six weeks and three sessions each week and each session lasted 30 minutes. After the training phase, the post-test phase was conducted, where the participants performed 9 archery throws, as in the pre-test phase, during which the electrical activity was recorded using an electromyography device. The data was analyzed by univariate covariance analysis.‎

The results indicated that progressive relaxation intervention on performance (P<0.05), the electrical activity of biceps muscle (P<0.05) and triceps muscle electrical activity (P<0.05) has a significant effect.‎

In general, the results of the present study emphasize the importance of a progressive relaxation program on muscle efficiency and archery performance.

Exercise has a great effect on health promotion, and recently its effect on improving the nervous system functions and cognitive processes has attracted the attention of many researchers. This study aimed to investigate the effect of internal and external attention during futsal dribbling skill training on the serum level of glial cell-derived neurotrophic factor (GDNF) and cognitive function.

forty-two untrained female students were selected by available sampling and randomly assigned into four Control without training, Control with training, Internal Attention, and External Attention groups. During 15 sessions, the participants of the training groups did the futsal dribbling training according to the dribbling test by making five trials in each session. Forty-eight hours before the pre-test and after the post-test, blood samples were drawn and cognitive function was measured using the Stroop test. GDNF blood factor was measured via the ELISA method. Statistical analysis was conducted at a significance level of P≤0.05.

Internal attention during dribbling training had no significant effect on GDNF serum level (P=0.12) and cognitive function (P=0.07). External attention during dribbling training had a significant effect on GDNF serum level (P=0.01) but did not have a significant effect on cognitive function (P=0.16).

The type of internal or external attention during futsal dribbling does not make a particular difference in cognitive function and increases the serum level of GDNF. But the effects of external attention on the serum level of GDNF have been significant.

This study aimed to compare motor skills in four groups of intellectual disability, Down syndrome, autism spectrum, and normal children.

The research method was descriptive and causal-comparative. The statistical population of this study included children aged 7 to 12 from centers for special needs in Rasht City in 2022. One hundred people (25 participants for each group) were considered as statistical samples. Eight sub-tests of the shortened form of Bruininks-Oseretsky Test of Motor Proficiency - Second Edition (BOT-2) were used to collect data. Analysis of variance test was used to analyze the research data at the significance level of 0.05.

The results showed that in the sub-tests of movement speed and agility, balance, strength, reaction time, upper limb dexterity, and the total score of motor proficiency, the performance of children with autism spectrum and Down syndrome was weaker than the other two groups (P=0.001). There was no significant difference between the two groups of normal and intellectually disabled children in the balance and strength subtests (P>0.05). Also, in bilateral coordination and visual-motor control subtests, children with autism had a weaker performance than the other three groups (P=0.001), and no significant difference was observed between the other three groups (P>0.05).

Considering the poor motor skills of children with autism spectrum and Down syndrome, and the effect of motor skills on social, academic, and learning skills, it seems necessary to include motor skills training and exercises for children with special needs at younger ages in educational programs of special schools and occupational therapy centers.
