Breathing is self-evident and often we are not aware just how much proper and efficient breathing is important in everyday life, in general and in particular for persons who are engaged in sports activities, whether they are recreational, amateur or professional. It has been proved that by learning and practicing breathing you can achieve better results in sport and improve your health status. Top athletes implement breathing exercises in different ways, but in recent years they have been using more breathing devices and yoga breathing exercises. Breathing devices are standardized technology and the results of their use are more defined professionally and scientifically. However, yoga breathing exercises are still unknown and unexplored field in Croatia, therefore I would like to introduce them in my thesis, not as the best form of breathing exercises but as one of possibilities which is more and more often used and accepted by athletes. The aim of this thesis is to show the importance of breathing exercises which are unknown in Croatian sport. With this thesis I would like to encourage trainers to conduct breathing exercises with their athletes in order to bring Croatian sport to a higer level.
