The spread of coronavirus in the world has had various effects on industries, especially the sports industry. The purpose of this study was to explain and classify the effects of coronavirus outbreak on the dimensions of the sports industry. The present study was applied in nature, mixed in terms of data retrieval and descriptive-exploratory in terms of data analysis method that data collection was done in the field. The statistical population in the qualitative section included sports experts, 18 people were purposefully selected, and the statistical population in the quantitative section included all activists in the field of sports and sports industry, of which 600 samples were selected by simple random sampling. Data collection in the qualitative part was done by the systematic method of data theory and in the quantitative part, using a researcher-made questionnaire obtained from the qualitative part of the present study with 79 items in 2 dimensions of direct effects and indirect effects on a 5-point Likert scale. Research data were analyzed using descriptive and inferential statistical methods with the help of SPSS24 and Amos statistical software. The results showed that the outbreak of coronavirus had a direct and indirect role in the production and distribution sectors, private and public sectors, sports education and research, trade, events and competitions, technology, services and economics of the sports industry. This finding can help the country's sports managers and officials to improve the situation of the sports industry in the post-Corona era.

This experiment assessed the effectiveness of two interventions; mental imagery and physical training as compared to a control group, on their ability to improve visuomotor accuracy, measured by scores achieved on a visuomotor task. For mental imagery participants had to imagine throwing a dart and for physical training participants physically practised dart throwing. Measurements were recorded pre-intervention, after two weeks of training (Mid-intervention), after five weeks of training (Outcome Measure 1) and two weeks after training (Outcome Measure 2). Comparison of Mid-intervention, Outcome Measure 1 and Outcome Measure 2 with baseline showed both interventions to significantly increase performance on dart throwing compared to the Control group. Our findings show that, as well as traditional physical practise, mental imagery can effectively improve performance on a fine visuomotor task. This is an important finding highlighting possible applications of mental imagery in those with limited motor abilities to maintain or enhance motor movement.
