Gierczuk, D, Bujak, Z, Cieśliński, I, Lyakh, V, and Sadowski, J. Response time and effectiveness in elite Greco-Roman wrestlers under simulated fight conditions. J Strength Cond Res 32(12): 3442–3449, 2018—The purpose of the study was to determine changes in response time and its correlations with tactical and technical actions performed by Greco-Roman wrestlers in a fight. Twenty wrestlers aged 19–25 (21.4 JOURNAL/jscr/04.03/00124278-201812000-00017/inline-formula1/v/2023-08-19T002809Z/r/image-tiff 1.8) years were divided into 2 groups, i.e., finalists of Polish Senior Championships (winners of 1st and 2nd places) and wrestlers who won 3rd–6th places in those competitions. The subjects from 1 group were individually paired with the wrestlers from the other group according to the same weight class. Response time before a fight and during the intervals between the 3 rounds was assessed. Batak Lite (test IV) was used in the study. The Polar M400 watch was used to register heart rate. Response time changed during a fight. The finalists showed significantly quicker reaction and performed a higher number of technical and tactical actions. The differences grew in the course of a fight, and the largest ones were observed during the third round. The strongest correlations were noted between response time and the number of technical and tactical actions performed during the third round (r = 0.77, p < 0.001). Response time is a significant determinant of wrestlers' results, which can be observed at submaximal intensity of the effort (176–195 b·min−1) during a fight.

The purpose of the study was to determine the changes in simple reaction time and to define correlations between simple reaction time and technical and tactical actions performed by elite Greco-Roman wrestlers during a match. Twenty Greco-Roman wrestlers (M age = 19.5 years, SD = 1.8) from the Wrestling Sports Centre in Radom participated in the study. Simple reaction time (including reaction time and movement time) before a match and after the first, the second, and the third round was analyzed. The wrestlers' reaction time and movement time changed in the course of performance. Wrestlers with higher sports achievements demonstrated a smaller decrement in simple reaction time and performed more technical and tactical actions during a match. The strongest correlations were observed between both reaction time and movement time and the number of technical and tactical actions performed during the last round. Quick reaction was a significant factor in determining the match outcome, which is revealed at submaximal intensity of the effort during a match.

Introduction. The aim of the study was to compare CMAs in elite wrestlers and taekwon-do competitors. Material and methods. Forty-nine Greco-Roman wrestlers and ITF taekwon-do competitors were included in the study. The wrestlers were 21.9±2.74 years old, while the taekwon-do competitors were 22.7±5.78 years old. The former group had between 7 and 14 years' training experience and the latter group had from 6 to 16 years' experience. All subjects were elite sportspeople (between first class and international master class levels). Five CMAs were assessed using 14 indices. Computer tests from the Vienna Test System were employed in the study. Results. It was shown that there were no significant differences in CMA levels between wrestlers and taekwon-do competitors. Wrestlers from higher sports classes outperformed competitors who possessed lower sports classes in the majority of CMA indices. Statistically significant differences were observed for simple reaction, movement coupling and high frequency of movements. Taekwon-do competitors at the international master sports class (IM) level scored better than athletes who were at national master class (NM) and first class (I) levels in spatial orientation, reaction time, movement coupling and high frequency of movements. Regardless of the type of combat sport, competitors demonstrated high individual differences in CMAs, which may indicate that a focus on coordination improvement could increase training effectiveness. Conclusions. Further research on identifying predominant CMAs in sportspeople at different levels of competition, particularly in those achieving significant sports successes may be conducted. Tests to thoroughly diagnose coordination should be employed in such investigations.

Introduction. The aim of this work was to assess selected validity criteria of motor tasks included in Batak Lite. The tasks are used to control coordination motor abilities in athletes of different sports. Material and methods. Twenty male Greco-Roman wrestlers from the sports school SMS in Radom were included in the study. They were 17-18 years of age and their training experience was 4-7.5 years long. The validity of motor tasks was determined on the basis of two criteria, i.e. reliability and diagnostic accuracy. To define the reliability of the tests, the research was carried out twice with an interval of 5-7-days (test-retest). Diagnostic accuracy of selected indices was determined with the help of three main criteria. The analysis included 6 motor tasks performed with the use of Batak Lite. Results. Tests I, II, IV and V are characterised by reliability coefficients higher than 0.50 and, regardless of the assumed accuracy criterion, by coefficients higher than 0.30. Thus, they meet the validity requirements within the assessed criteria. The highest accuracy coefficients were observed in motor tests assessing quick reaction (r = 0.46-0.63), simple reaction including sensory (r = 0.61-0.78), motor (r = 0.33-0.46) and complex (r = 0.34-0.49) reactions as well as spatio-temporal orientation (r = 0.33-0.49) and movement coupling (r = 0.34-0.49). Conclusions. Four Batak Lite tests displayed sufficient reliability and diagnostic accuracy. Therefore, they can be implemented in the training process of wrestlers. The strongest correlation was noted between Batak Lite tests and motor tests that assessed quick reaction, spatio-temporal orientation and movement coupling.

Introduction. The aim of the study was to identify correlations between general physical fitness (independent variable) and sports result (dependent variable) of junior taekwondo athletes. Material and methods. Of all the subjects n = 104 there were 62 male and 42 female juniors at the level of at least the 6 th kup. The research was conducted with the use of the International Physical Fitness Test (IPFT). A sports result was defined by the place won at Polish Junior Championships in 10 weight classes. The analysis regarding the significance of differences between groups was done by means of one-way ANOVA variance. Results and Conclusions. It was observed that a sports result in female junior taekwondo athletes was conditioned by the power of lower extremities, strength and endurance. In the case of males, however, it was not clearly determined what a sports result depended upon.
