RELATIONSHIPS AND INFLUENCE OF ANTHROPOMETRIC CHARACTERISTICS AND PHYSICAL FITNESS PARAMETERS IN 100 M SPRINT RUNNING IN ADOLESCENTS

In this paper, we have searched the relationships and influence of anthropometric characteristics and physical fitness parameters in 100 meters sprint running in teenagers. The purpose of this paper is to prove the relationship between anthropometric characteristics and physical fitness parameters as a predictor system in the 100 meter sprint running as a criterion system. The research was carried out in 170 male subjects aged 14 years ± 6 months, in the primary schools "Bajram Shabani" and "Naim Frashëri" - Kumanovo, Rep. of North Macedonia. A total of 12 variables were used in the research, of which 7 variables were used for the assessment of anthropometric characteristics, including: body height, body mass, body mass index, chest circumference, thigh circumference, thigh fat and abdominal fatty tissue, 4 variables for evaluating physical fitness parameters, including: 10x5 Shuttle run, agility T-test, standing long jump and standing high jump, and 1 variable for evaluating speed, also: 100 meter sprint running. Based on the results obtained and the analysis carried out, we can conclude that: the variables of anthropometric characteristics and the parameters of physical fitness (as a predictor system) have a statistically significant impact on the in 100 meters running criteria variable, at the level of reliability q=.000. It’s also worth noting that from the entire predictor system, the greatest individual impact on the 100 meter run criterion variable, have variables: standing long jump (MKGJV) with a negative beta coefficient value of -.330 and a reliability level of .000, T - agility test (MTT) with a positive beta coefficient value of .187 and a reliability level of .003 and 10x5 Shuttle run (10x5Sh) with a beta coefficient value of .150 and a reliability level of .032. From these results, we can conclude that adolescents of this age who have developed physical fitness parameters such as explosive strength of the lower limbs and speed with a change of direction – agility, achieve better results in 100 meters sprint running and also we recommend that the same tests be applied by athletics trainers to identify sprint running talent.
