Abstract
Massive amount of practice over many years raise the question that handling class of action by generalized motor program may modify over years. The purpose of the present study is to provide evidences to investigate this hypothesis by examining the pattern of co-activation and agonist to antagonist activity ratio. Seven experienced darts players were asked to execute from standard dart distance (fourth distance) and six other farther and nearer distances, making 252 throws. Relatively, the results showed that at least in five from the seven samples, there was a significant difference in muscle co-activation between fourth and six other distances. These findings do not support the existence of a generalized motor program at fourth distance so that performance of elite players met limited generalizability

Effect Of Variable Practice In Physical Execution And Action Observation On Learning Golf Putting

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.

Abstract
Introduction and Purpose: Given the rapid pace of technological changes, any business that fails to adapt to environmental changes will undoubtedly fall behind in the competition. Therefore, in order to take advantage of emerging opportunities, entrepreneurs must make decisions in the shortest possible time. This makes entrepreneurial decision-making more complex and challenging. Accordingly, the present study aimed to investigate opportunity exploitation decisions with an emphasis on the role of entrepreneurial personality in sports businesses.
Methodology: This research employed a mixed-methods approach and is classified as developmental-applied in terms of its objective. In the first step, through meta-synthesis of 32 scholarly articles, 36 indicators were identified. In the second step, using thematic analysis of interviews with academic experts, 36 indicators were extracted, of which 27 were confirmed through the Delphi method. In the third step, narrative inquiry was used to explore the lived experiences of six entrepreneurial leaders in the field of sports, leading to the identification of 34 themes.
Findings: Based on the results, after integrating the three stages, 44 indicators were classified into seven dimensions. The validity and appropriateness of these dimensions were confirmed using the t-test and the four criteria of coherence, comprehensibility, generalizability, and control.
Conclusion: The findings suggest that entrepreneurial personality significantly contributes to improving decision-making regarding opportunity exploitation in sports and reducing environmental risk. This is achieved through the development of seven key roles: self-efficacy, autonomy, risk-taking, personal traits, creativity, perseverance, entrepreneurial networking, and entrepreneurial skills and experience.
