Race walking (RW) is a cyclic athletic discipline, of aerobic character, which is characterized by high intensity and high energy consumption. The result is correlated with the anthropological dimensions of the walker as well as good technical performance. The study includes 25 male students, third year of study, Faculty of Physical Education and Sports in East Sarajevo. For the purposes of the research, the results of RW at 2km (criterion variable) were measured, on the basis of which average values of walking speed (WS) were calculated. The aim of the research was to determine the correlation between the achieved result depending on the walking speed. By applying the Pearson product of the correlation moment, the obtained results confirmed a significant and high correlation between the result and the walking speed (r = -0.988; p<0.05) with an inverse function that confirms the high dependence of the result on the WS. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0778/a.php" alt="Hit counter" /></p>

Background: The Worlds Athletics Championships, along with the Olympic Games, represent the largest review of athletes in which they record top results, often projecting new world records. Any research that analyzes top athletes contributes to shedding light on a number of issues. It is especially interesting to analyze and compare the results of athletes from one time distance. The main goal of the research was to determine the result differences in sprint, jumping and throwing disciplines, between men's and women's finalists participating in the World Athletics Championships in Edmonton, 2001 and Doha in 2019. Methods: the current study included a total of 493 finalists (247 men's and 246 women's) of the World Championships in Edmonton, 2001 and Doha, 2019. The results in sprint, jumping and throwing disciplines were analyzed in order to determine the result differences in the championship finals. To obtain the necessary information, a t-test for independent samples was applied and the relevant statistical parameters were calculated. Results: the results were confirmed between the final evident differences in all disciplines. Men in Edmonton were successful in 41% of the discipline (400m, pole vault, discus throw, hammer throw, javelin throw), and in Doha 59% of the discipline (100m, 200m, 110H, high jump, long jump, triple jump), while in the category of women's finalists, participants in Edmonton were successful in 17% of disciplines (long jump, throwing the ball), while female athletes were successful in 83% of disciplines (100m, 200m, 400m, 110H, triple jump, high jump, high jump with a pole, Throwing a spear, throwing a discus, throwing a hammer). Statistically significant differences between male finalists were recorded only in the disciplines: 200m (t=2.318; p<0.039) , throwing the ball (t=-2.939; p<0.009) and hammer throw (t=-2.802; p<0.013) , and in female finalists in the 200m disciplines (t=2.402; p<0.025) , pole vault (t=-5.552; p<0.000) and hammer throw (t=-6.410; p<0.000). Conclusion: the consequences of this distribution of differences finalist can be found in various morphological, motor and biomechanical parameters, technical experience, neuromuscular movements, level of motivation and preparedness at the time of onset and other endogenous-exogenous factors.

Purpose: The aim of the study was to determine the differences between football players and basketball players in the mean absolute values ​​of maximum torque flexors and extensors, ratio of maximum hamstring torque to maximum quadriceps torque dominant (DOM) non-dominant (ND) leg and differences in bilateral imbalance of flexor muscles and knee extensors. Material and methods: The research included a sample of 39 professional athletes. The first subsample included 19 professional basketball players while the second subsample included 20 professional soccer players. Results: Based on the results of the torques of the extensors in the knee joint of the DOM and ND legs, it was established that there is no statistically significant difference between basketball players and football players. However, a statistically significant difference was found in the torque flexors of the knee joint DOM (p≤0.01) and ND (p≤0.00) of the leg between basketball players and football players. On the other hand, the results of the research indicate that the difference between basketball players and football players in the ratio of Hamstrings peak torque to Quadriceps peak torque was recorded only in the ND leg (p≤0.02), while the difference in the DOM leg is not statistically significant. The results of our study indicate that basketball players have a higher percentage of imbalances compared to football players, especially in m. hamstrings. Conclusion: This study provides normative data on populations specific to soccer and basketball, but does not provide evidence of the ability of the isokinetic assessment of lower extremity muscle strength to predict injuries to football players and basketball players.

СажетакЦиљ истраживања био је да се испита постоји ли утицај Ефекта релативне старости (ЕРС) на селекцију тринаестогодишњих кошаркаша. Узорак испитаника чинило је 20 кошаркаша (ТВ=177.35цм±6.73, ТМ=61.42кг±8.98, просечне старости 13 година и 7 месеци ±.28, просечног искуства у кошаркашком тренингу 4 године и 6 месеци ±1.15). Узорак је подељен у 2 групе: 11 кошаркаша рођених у првој половини године и 9 кошаркаша рођених у другој половини године. Помоћу One-way ANOVA-e анализиране су разлике између 2 групе кошаркаша у сету антропометријских варијабли (Телесна висина, Распон руку, Дохватна висина, Телесна маса и Проценат масног ткива), моторичких варијабли (Брзина нервно-мишићне реакције, Вертикални скок, Спринт на 5 метара, Спринт на 10 метара, Спринт на 20 метара, Т-тест, Цик-цак тест, Бацање лопте из седећег положаја, Лежање-сед за 30 секунди и Дубоки претклон из стојећег положаја) и једне функционалне варијабле (20-M shuttle run test). Испитаници се не разликују у сету параметара, осим у једној варијабли (Лежање-сед за 30 секунди, p=.040). Дошло се до закључка да није утврђено постојање ЕРС-а на овом узорку испитаника.Кључне речи: КОШАРКАШКИ ТРЕНЕРИ / ПУБЕРТЕТ / ФИЗИЧКЕ КАРАКТЕРИСТИКЕ Кореспонденција са: Игор Вучковић, Универзитет у Бањој Луци, Факултет физичког васпитања и спорта, Булевар војводе Петра Бојовића 1, 78000 Бања Лука, Република Српска, БиХ.
