Sports psychology is becoming more and more popular nowadays. Professional or sports burnout is a psychophysiological reaction that is the result of an ineffective effort to achieve the set goals of a sports competition or training. Various studies on this topic show that emotions, motivation and burnout are closely related. Also very important is the relationship between motivation and sports burnout, which has been often studied by sports psychologists in recent years, and research results show that there is a connection between the level of autonomous and controlled motivational regulations and burnout. In addition to the above mentioned items, materialism has recently played an increasingly important role in sports. Since investments in sports are constantly increasing, materialism among individual athletes is becoming an increasingly pronounced construct. Considering all the above, the goal of this research was to examine different forms of motivation, professional burnout and materialism in professional basketball and soccer players. In addition to the mentioned variables, the research also examines some variables that were assumed to play a role in the explanation of the mentioned constructs. These are: the number of years spent in professional sports and satisfaction with the professional contract. 112 participants took part in the research, of which 58 are professional basketball players who play in the Premier League, and 54 professional football players who play in the 1st HNL. The Croatian version of Professional Burnout Questionnaire of Athletes was used to examine professional burnout. Motivation was examined with Croatian version of the Athlete Motivation Quality Scale, while the Croatian version Materialistic Value Scale was used to examine materialism. A positive relationship between the number of years and a negative relationship between satisfaction with the contract and the level of burnout was determined. The connection of controlled regulation with the degree of materialism was also confirmed. No differences were found between soccer players and basketball players regarding the level of burnout and different dimensions of motivation. Examining the set of predictors of materialism, number of years in sport and satisfaction with the professional contract in the explanation of controlled regulation and burnout, their significant contribution was determined. On the other hand, no significant contribution of the set of predictors in the explanation of autonomous regulation was found.
