Abstract

In this study, the correlation and influence of morphological parameters and speed on the success of the long jump was investigated. The main aim of this study was to predict long jump performance based on morphological parameters and speed in male athletes. The research was conducted on a sample of 110 tester’s aged 13 years ± 6 months, students of the "Bajram Shabani" elementary school - Kumanovo. A total of 9 variables were used in the research, of which: 6 variables for the assessment of morphological parameters (height, weight, body mass index, triceps adipose tissue, back adipose tissue, abdominal adipose tissue), 2 variables for the assessment of speed (running 60 meters, running 100 meters) and 1 variable for assessing situational-motor skills (long jump – collected technique). The highest correlation appeared between the variable 100 meter run (VR100m) and long jump performance (SMKGJ), with a negative value of -.453**. Multiple correlation revealed that the joint contribution of all independent variables to the evaluation of long jump performance is (R=549, R2=301), which indicates that 30.1% of long jump performance is derived from these variables. Of all the predictor variables tested in this paper, statistically significant influence on the dependent variable of the long jump (SMKGJ), there are only variables of the 100 meter run (VR100m), with a negative value of the standardized beta coefficient -.405 and with a level reliability 008.
