    Differences of Duration of the Fight Depending on the Stage of the Judo Competition
    (Horizon Research Publishing, 2020) Ahmedov, Farruh; Gardašević, Novica; Norboyev, Komiljon; Umarov, Karim
    The purpose of this study is to compare the time characteristics of introductory and final rounds of judo competitions. This study analyzed 656 male judo fights in National Championships of Uzbekistan which were held in 2018 and 2019. All competition rounds were divided as first and the second subsample. Results were processed at the level of descriptive statistics. Descriptive parameters were counted: Average Indicator (M), Standard Deviation (SD), Minimal (Min) and Maximal (Max) results. The normality of the distribution of findings was tested using the Kolomogorov-Smirnov test and the T-test for independent samples was applied. Data were processed using the IBM SPSS Statistics 20.00 statistical package. The research results show that judo fights last longer in the second phase of the competition. The difference in the duration of the judo fights is - 63.47 seconds, i.e. the fight in the second phase of the competition lasts significantly longer, about 1.03 minutes. The results indicate that in judo both anaerobic and aerobic exercises are essential to get high achieves. High endurance capacity plays a crucial role in last rounds of the competition. This investigation would help to improve competitive effectiveness judokas, results would be clear indication of how to energy expenditure in a various rounds of the competition. Time characteristics of each phases of the contests are directly connected with physiological bases of judo such as energy consumption, VO2 intake and Blood Lactate concentrations of the athletes during the different rounds.

    INFLUENCE OF BODY COMPOSITION PARAMETERS ON ANAEROBIC STRENGTH OF LOWER EXTREMITIES IN FEMALE FOOTBALL PLAYERS
    (2020) Lilić, Ana; Joksimović, Marko; D’Angelo, Stefania; Karišik, Siniša; Hamad, Shamal; Gardašević, Novica
    The aim of this study was to investigate the influence of body composition on the anaerobic strength of the lower extremities, as well as the prediction of body composition on the results of anaerobic ability in professional football players. Materials and Method. The sample of respondents consists of female football players who compete in the highest rank of the competition, the Serbian Super League. The total number of respondents included in the study was 21 female football players (age 19.38 ± 3.69, body height 166.48 ± 6.17 cm, body weight 59.98 ± 7.09 kg). The study is of a transversal nature and testing was done in the pre-competition period. The sample of measuring instruments used in the research are body composition and assessment of anaerobic strength of the lower extremities. Assessment of body composition was performed indoors using a multifrequency bioelectric impedance (Inbody 770). Variables for estimating the anaerobic strength of the lower extremities were obtained using a bicycle ergometer (Monark 839E) in the Wingate Anaerobic Test. Results. The results of body composition show a statistically significant influence on the prediction of maximum anaerobic strength of the lower extremities in professional female football players (p < 0.05), as well as on the overall work in the anaerobic zone and the mean values of anaerobic strength. Regression analysis of the influence of body composition on the parameters of maximum strength in (W / kg) and fatigue rate does not show statistically significant results. Conclusion. There is a statistically significant influence of body composition, such as: body weight, lean body mass (%), muscle mass in absolute and relative values, on the values of maximum anaerobic strength, mean values of anaerobic strength and overall work in professional female footballers
