The aim of the study was to determine the anthropometric and fitness profiles of European half-heavyweight judokas by success in competition. For this purpose, we compared 5 international medalists (elite) with 5 national medalists (subelite). All male judokas won at least 1 medal in the half-heavyweight category during the previous 2 years. The testing in this cross-sectional study was performed during 4 days. All subjects underwent anthropometric assessment with body mass, height, skinfold, and limb circumference measures, and the body fat percentage was estimated by manual bioimpedance. The physical fitness evaluation consisted in peak torques for thigh and shoulder muscles, handgrip strength, high and long jumps, medicine ball throw, pull-ups, deadlift, bench press, deep squat, V[Combining Dot Above]O2max, Max Power, and Tokui Waza tests. The statistical analysis by the Student's t test showed significant differences for forearm and upper-arm circumferences, peak torques, pull-ups, bench press, deadlift, deep squat, V[Combining Dot Above]O2max, Max Power, and Tokui Waza tests. Our results showed that elite judokas have a superior fitness profile than subelite athletes from the half-heavyweight category. Moreover, elite judokas seem to have a higher arm muscle mass than subelite athletes but a similar body fat percentage. This study could be of interest for judo coaches with athletes competing in the half-heavyweight category, as some tests that discriminate by judo success for this specific weight category are described. Few studies analyze anthropometric and fitness profiles in half-heavyweight male judokas, so additionally our results can be used as a reference for coaches, athletes, and scientists.
Exercise training may increase production of free radicals and reactive oxygen species in different ways. The training type and intensity may influence free radicals production, which leads to differences in oxidative stress status between athletes, but the results of the previous studies are incosistent. The aim of our study was to estimate oxidative stress status in elite athletes engaged in different sport disciplines. The study included 39 male highly skilled professional competitors with international experience (2 Olympic players): 12 wrestlers, 14 soccer players and 13 basketball players in whom we determined the levels of advanced oxidation protein products (AOPP) and malondialdehyde (MDA), as markers of oxidative stress and the total antioxidative capacity (ImAnOX) using commercially available assay kits. The mean AOPP concentration was not significantly different between soccer players, wrestler and basketball players (60.0 ± 23.0 vs. 68.5 ± 30.8 and 80.72 ± 29.1 μmol/L respectively). Mean ImAnOX concentration was not different between soccer players (344.8 ± 35.6 μmol/L), wrestlers (342.5 ± 36.2 μmol/L) and basketball players (347.95 ± 31.3 μmol/L). Mean MDA concentration was significantly higher in basketball players (1912.1 ± 667.7 ng/mL) compared to soccer players (1060.1 ± 391.0 ng/mL, p=0.003). In spite of this fact, oxidative stress markers levels were increased compared to referral values provided by the manufacturer. Type of sports (soccer, wrestler or basketball) have no impact on the levels of oxidative stress markers. Elite sports engagement is a potent stimulus of oxidative stress that leads to the large recruitment of antioxidative defense. Oxidative stress status monitoring followed by appropriate use of antioxidants is recommended as a part of training regime.
This study aims to determine the effects of a program based on a progressive increase in the number of nage-komi repetitions (throws) on a specific judo fitness test (SJFT). The research was conducted on a total of 20 respondents. In SJFT for research purposes, 12 variables. Descriptive statistics and paired t-tests for dependent samples of initial and final testing were used for data processing. The results of the study showed significant statistical deviations in the number of throws in the first 15 seconds, with the pulse measured immediately after testing and the SJFT index (p <005). There is a noticeable need for a table to classify SJFT results for young judoists. Based on the obtained results, we can conclude that the programmed activity had positive effects on the results of the SJFT, ie that the index was statistically significantly lower in the final than in the initial testing. Taking into account the results obtained, calculated by the SPSS 22 t-test for dependent variables, the values ??of the young judoist index and the values ??of the senior index show noticeable differences. While their results can be classified into appropriate categories, the results of young judoists can be classifieclassifiedrity, under, ad and the rest as very bad. Some results could not even be ranked, so we conclude that it is necessary to make tables for classifying the results of young judoists. The obtained results can be used as guidelines for more efficient programming of the training process. Keywords: cadets, judo, juniors, SJFT test, training.
