    Background: Long jump are cyclic-acyclic movements of maximum intensity. It is a discipline that combines speed and jump in technique, that is, the speed-strength properties of competitors. Speed, agility and explosiveness are of special importance in jumpers. The main goal of the research is to determine the influence of Body height (BH) and Body weight (BW) with the best achieved results of Long jump. Material and methods: In study included 21 top male jumpers (BH=184.19±4.68cm; BW=78.86±6.81kg). Their achieved best results were analyzed. Pearson correlation coefficient was used to determine the relationship between body height and body weight and the results of long jumpers. Univariate model of regression analysis was applied and the relevant coefficients were calculated. The level of acceptance of statistical significance was set to p<0.05. Results: Simple regression analysis did not show a statistically significant effect of Body height on the results in the long jump (BH vs. Long jump R=0.183; p>0.05), while Body weight confirmed a significant inverse relationship with the results of the jump (BW vs. Long jump R= - 0.442; p<0.05). Conclusion: Long jumpers contain a large percentage of active muscle mass that integrates and generates motor explosive abilities for the success of long jumpers, primarily strength and speed, which is confirmed by the results of the study. However, a good jump technique is also necessary, but with optimal body weight, because any increase in weight has a negative effect on the length of the long jump.

    In a sample of 80 respondents, population special forces, divided into three subsample age: the first group of 27 to the age of 25 years, the second group of 28 aged between 26-30 years and the third group of 25 aged 31 - 36, made a study of motor abilities as part of the program structure to carry out the unit. In this research procedure isolated four motor variables: push-ups, abdominal muscles, pull-ups and running the 3000m. For each of the variables according to the number of the engine under test and the time for running the 3000 meters obtain credits. In the research procedure was used descriptive method, classification of frequencies of the motor performance and determining, the impact of the criterion on prognostic variables and determining the differences between respondents. The results of descriptive statistics, we can conclude that the variables push-ups, sit-ups and points, there are major differences in the tests, which bear witness high rates of standard deviation, showing a greater deviation from the average value, and coefficients of variability that tell us higher percentage of variation of the standard deviation from the mean. The results of the regressive analysis show statistical significance, that motor variables as significant prognostic influence criteria variable, which tells us that the points scale better evaluates the results and is a good representative as a criteria for achieved results. As a general conclusion of the research in three subsample respondents according to age, we can conclude that there are no statistically significant differences between them, and the majority of respondents are in good physical preparation.
