The aim of this research is to identify the motivational structure of recreational exercisers and to investigate differences in motivation with respect to gender, ie to determine the hierarchy of motives for which they choose recreational exercise. This research shows that the strongest motivation for recreational exercise is maintaining and improving health, and certainly relaxation. After them, the most important motivation is socializing and meeting new people, and improving and maintaining physical ability. The research also showed that there are very small differences in the motives for exercise in relation to the age of the respondents, and they are reflected in good looks and fun, while relaxation and relaxation and improvement and maintenance of physical ability are equally important for all ages.

This research is aimed to determine the differences in the racing performances of elite European and Latin American footballers. The research was conducted on a sample of N = 157 top football players, aged 19 to 35, who played all 90 minutes in the first round of the group stage of the competition at the 2018 World Cup. Respondents were classified into two groups, where group I (N = 103) consisted of football teams from Europe, and group II (N = 54), consisted of teams from Latin America. The obtained data showed that 8 out of 13 variables have the characteristic of heterogeneity with a higher value of variance than the arithmetic mean. The results of the T-test showed that only 4 of 13 variables had statistically significant differences. Footballers from European national teams are on average taller than Latin American footballers by just over 3 cm. European footballers had a 4% greater (p> 0.05) total distance traveled, distance in the first and second half of the game than Latin American footballers.

This research aimed to determine the differences between the junior (U18) water polo players of five Croatian and one Montenegrin clubs in the anthropometric characteristics and body composition. The first sample of the subjects consisted of 14 players of the water polo club Mladost average age 17.57 ±0 65, the second sample consisted of 11 players of the water polo club Sibenik (17.82±0.65), the third sample consisted of 13 players of the water polo club Primorje (17.23 ±1.01), the fourth sample consisted of 15 players of the water polo club Mornar (17.13 ±0.64), the fifth sample consisted of 13 players of the water polo club Medvescak (17.92 ±0. 6) and the sixth sample consisted of 10 players of the water polo club Jadran Herceg Novi (Montenegro) (17.70 ±1.34). In the 2010–11 season, these clubs participated in Regional Water Polo League, commonly known as the Regional League or Adriatic League in Sou theast Europe. The measurements was conducted in the competition season in the period September-December 2010, at sports centers and swimming pools of water polo clubs that participated in the research. Anthropometric characteristics and body composition were evaluat d using a battery of 12 variables: body height, body weight, arm length, arm span, leg length, foot length, chest skinfold, trice ps skinfold, back skinfold, abdominal skinfold, upper leg skinfold and body mass index. The standard central and dispersion parameters of al l variables were calculated. The significance of the differences between the water polo players of six teams in the variables for ssessing anthropometric characteristics and body composition were determined using ANOVA and an LSD Post Hoc test.Based on the central a nd dispersion parameters, it can be stated that the values of all the variables are highly similar to all of the water polo player s of these six clubs. The ANOVA test found that the water polo players of the six international clubs do not have statistically significant di fferences in the variables for assessing anthropometric characteristics and body composition.
