**5. Conclusion**

Physical activity and sports are irreplaceable activities for young people. Particularly after the period of the COVID-19 pandemic, when physical activity decreased, because physical education in school was mostly not taught online and also because there was a curfew and businesses that provided physical activities and sports were closed. Participation in physical activities and sports is closely related to well-being and feelings of happiness, as shown by our findings, where sports-active boys were statistically significantly happier than sports-inactive boys, and also sports-active girls were happier than sports-inactive girls also on the significance level. The happiest were those who exercised six times a week.
