Introduction

Abstract

Exercise culture and a healthy lifestyle are the current leading trends that are becoming part of the daily lives of an increasing number of people. These trends can also be observed from the enormous growth of the number of personal trainers, nutrition counselors, and mental coaches, as well as health and exercise mobile applications. The official sports policy of almost all governments is aimed at promoting mass sports and exercise in general. Opposite to the exercise culture associated with a healthy lifestyle stands professional sport. It contains a relatively small group of professional athletes who get support from teams of specialists in various fields and whose performances and results generate billions in revenue, transforming the sport into a regular business.
