The health effects of playing golf on the athlete's body is an interesting topic. The effect of golf on increasing blood saturation has low presence in the literature. This paper demonstrates the correlation of playing golf on improving health status after COVID-19 while this positive information has a potential to be used by the marketing management of various organisations to improve economics of golf activities. We analyse the change in saturation and heart rate after playing an 18-hole course, measured by pulse oximetry (% SpO2). Then we investigate the different aspects that have the greatest health benefit in golf. By following the effect of playing golf on blood oxygen saturation and heart rate in athletes we build a linear regression model explaining the impact 14 factors have on blood oxygen saturation. An 18-hole golf course caused a 1 ± 1.49% (p < 0.001) increase in venous blood O2 concentration and a 6 ± 8.09% (р < 0.001) increase in resting heart rate. Golf has the positive effect on the health status of athletes after recovery or vaccination for COVID-19 disease.

Retail chains are the dominant player in the distribution chain, which mainly provides consumer goods to final consumers. The distribution of individual retail shops in towns and villages is related to the demography of the selected region and to the degree of urbanisation. Due to the relative saturation of the market with retail chain shops, there is a renewed need for diversification. Given a good demographic structure of the population, it is possible to diversify through new technologies, including electromobility. The aim of the article is to describe the expansion of retail chains in a selected region considering its demographics, while evaluating the potential for installation of charging stations for electric cars as an element enabling to gain and retain customers.
