This research main goal is to determine differences in maximum upper knee musculature torque moment of judo, football and handball players. For the needs of the research, 30 respondents were tested, of which 10 were football, 10 handball players and 10 judo athletes. Testing was conducted in Isokinetic Diagnostic Cabinet of the Provincial Institute for Sports and Sports Medicine in Novi Sad on the isokinetic dynamometer “Easytech prima DOC”. Significant differences were noted in the maximum torque moment of both legs extensors force (PTQR, PTQL) between judo athletes and football players, in favor of judo. Obtained results between observed groups can be attributed to the various sports branches training processes specificities, i.e. performing certain techniques in the sport itself

This research aims to determine the relationship between morphological characteristics and abilities in volleyball players. It was conducted on the territory of Vojvodina autonomous province on a sample of 27 male volleyball players with an average age of 17.48 ± 0.50 years and an average sports experience of 6.33 ± 2.83 years. A test battery consisting of five variables for measuring morphological characteristics and twelve tests of abilities was applied: flexibility, speed, agility, endurance, static and explosive power. The normality of the data distribution was controlled by the Shapiro-Wilk test, and the connection between morphological characteristics and abilities was calculated by the Spearman ro correlation coefficient. The limit value for testing the normality of distribution of p> 0.05 was not met by: body mass index (p = 0.01), straddle in supine position (p = 0.03), single leg counter movement jump with the left leg (p = 0.01) and Yo-Yo Intermittent endurance test level 2 (p = 0.02). The connection of morphological characteristics with explosive power tests is especially noticeable, the most significant is the range of arms span with continuous jump with bent legs (ro = 0.75), single leg counter movement jump with the right leg (ro = 0.74) and Counter movement jump (ro = 0.63). The main finding in this study is that morphological characteristics are mostly negatively correlated with the explosive power of volleyball players. It is known that these characteristics and abilities have a significant share in the model of the ideal volleyball player and therefore their negative connections, the approach to the selection of volleyball and volleyball training must be based on scientific knowledge. Key words: measurement, testing, diagnostics, test batteries, volleyball

Through their actions and behavior forms, coaches set an example for the athletes they work with, and additionally oblige them to lead a healthy lifestyle, which includes a proper diet and regular physical activity manifested in various forms. The aim of the paper is to compare the categories of physical activities between male and female sports experts. The results of the research showed that 63% of trainers practice high physical activity, and 36% moderate physical activity, with women applying high physical activity by 6.8% more than male sports experts. Observed physical activity is expressed in MET units (metabolic equivalent of task). The analysis of the chi-square test did not show a statistically significant difference in the representation of physical activity categories among male and female sports experts. The observed level of physical activity (light, moderate, heavy, total physical activity), analyzed using the t-test for independent samples, did not show a significant difference between male and female coaches. Keywords: coaches, IPAQ questionnaire, MET-values, lifestyle
