The Effect of External and Internal Focus of Attention on Shot Put Skill
Samaneh Damanpak, Mohsen Shafizadeh, Abbas Bahram, Elham Fazel,
Volume 1, Issue 2 (12-2011)
Abstract
The purpose of the present study was to study the effect of attentional focus instructions on motor skills that requiring near to maximum force production, such as shot put skill. In this experiment, twenty eight right- handed girl students with little shot put experience were selected voluntarily. They divided to two groups (internal and external focus) based on their shot put scores in pre- test (consists of 3 trial). They were asked to shot put using O׳brien technique. Experiment performed in three sessions and each session consists of three trials. Instructions referred specifically either to body movement (internal focus) or to shot (external focus). In this study, mixed ANOVA 2(group) ´ 3(session) with repeated measures on last factor is used for analyzing data. The results of this experiment showed that distance of shot put was greater in external focus group rather than internal focus group. Also interaction between attentional focus and practice session was significant (P< 0/001). In conclusion, external focus resulted in producing greater force relative to internal focus. These findings indicate that previously shown benefits of an external attentional focus generalize to motor skills requiring maximal force production.
Effect of skill level on variability of intra limb coordination and control variables in top spin strike
Dr Hamid Reza Taheri, Mr Mohamad Reza Ghasemian Moghadam, Mr Davood Fazeli,
Volume 6, Issue 12 (11-2016)
Abstract

The purpose of this study was to examine the effect of skill level on variability of
intra limb coordination and control variables in top spin strike. The 16 participants
of this study were divided into two groups of Skilled and Novice. The Skilled group
was consisted of players who ranked as 8 top in national ranking at their age stage
and the Novice group was consisted of players who recently learned the top spin
skill. They performed 10 top spin strikes with emphasis on speed and accuracy.
Movement kinematics were recorded and analyzed. There was a difference
between these two groups in variability of intra limb coordination (p<0.05) and the
Skilled group performed more consistent. However, there was not any differences
between these two groups in movement control variables (all p>0.05). This study
showed that the skilled performers have more consistency in their movement
patterns, while it could be no difference with novice performers in control variables
as cause of task constraints.


Designing a Model of Developing Sportsmanship in Iran Sports
Dr Hossein Zareian, Dr Mohammad Sadegh Afroozeh, Dr Mohammad Hoseen Ghorbani, Dr Mahmud Fazel Bakhsheshi,
Volume 10, Issue 20 (11-2020)
Abstract
The journey from championship to Sportsmanship status is a very difficult but possible way, so purpose of the research was to design a model for developing sportsmanship champion in the sport's Iranian. The present study was Exploratory qualitative research approach of grounded theory approach of Strauss and Corbin (1998) performed. The statistical population was including experts and elites who were selected by theoretical and non-random, Purposive sampling. Data were collected through interviews and field notes. The researcher reached theoretical saturation after performing 19 interviews and data from the interviews were analyzed through the coding method in three stages: open, axial, and selective. The findings were based on context include 10 components (corrupt contexts, ethics, economics, forgetfulness, ineptitude, bias, defective structure, official conflict, interaction, and indifference), Intervention-centered coding results consisted of 8 components (communication, aristocracy, religiosity, antiquity, culture, structure, politics, and society), strategy coding results including 8 components (deviation monitoring, culture building, structuring, reverberation, self-education, and training). It seems that three elements of community, sport and individual are effective in the development of athlete's athletic development and the suggested strategies of this research can help to achieve this.

Effect Of Variable Practice In Physical Execution And Action Observation On Learning Golf Putting
Davoud Fazeli Kasrineh, Hamidreza Taheri, Alireza Saberi Kakhki,
Volume 14, Issue 27 (8-2024)
Abstract
The purpose of this study was to investigate the effect of practice variability in physical compared with observational practice on golf putting performance. To this end, 50 male right-handed students (25±3.7 years) participated in this study. Participants were randomly divided into 5 groups (physical constant, physical variable, observational constant, observational variable, and control). During acquisition, the physical variable group randomly performed 50 trials from 5 different starting points to 2 different targets, but the physical constant group performed 50 trials from one starting point to one predetermined target. The observational variable and constant groups observed the performance of the physical variable and constant groups, respectively. The control group just participated in pre-and post-tests. Participants performed a test just like the pre-test 10 minutes and also 24 hours after practice. Putting accuracy was measured as the dependent measure. Results showed that variability of practice had a positive effect on performance than constant practice in physical and observational conditions. Maybe the similar underlying mechanisms and also the similar feedback effects resulted in the higher performance of the variable group than the constant group in physical performance and action observation.

The effect of inducing positive stereotypes on perceived competence, interest and learning soccer skill in adolescent girls
Fatemeh Jookar, Davoud Fazeli,
Volume 100, Issue 100 (10-2020)
Abstract
The aim of the present study was to investigate the effect of inducing positive stereotypes on perceived competence, interest and motor learning in adolescent girls. Therefore, among all of the adolescent girls in Shiraz, 30 adolescent with the age range of 10-13 years were selected by convenience sampling. Participants performed 10 trials as a pre-test and afterward, they were randomly divided into two groups  . The acquisition phase consisted of 50 trials (5 blocks of 10 trials), and the task required participants to perform inside kicks at targets area attached to a wall and touching the ground. Twenty-four hours after the acquisition phase, participants attended retention test (with 10 trials) to check learning effects on them. The participants were asked to answer the questions related to perceived competence and interest before pre-test, after the acquisition phase, and before the retention test. To analyzing data, one way and Mix ANOVAs analysis and Independent T test were conducted using SPSS21 at significance level P≤0.05. The results showed that in the acquisition phase, all groups significantly increased their accuracy, though difference among groups was not significant. Also, the results showed that the induction of positive stereotypes led to higher perceived competence and motor learning in adolescent girls
