Background and Study Aim. The importance of psychophysiological features in optimizing the functional state of athletes is beyond doubt. The aim of this study was a comparative analysis of the psychophysiological features of taekwondo athletes of different age groups. Material and Methods. The study involved 42 taekwondo athletes, skill level 2 Gup – 1 Dan. The participants were divided into groups of 14 people. Group 1 – (7.50±0.14) years, Group 2 – (10.07±0.22) years, Group 3 – (13.36±0.27) years. A special computer program for devices with the iOS operating system was used. The Apple iPad, 4th generation with a screen diagonal of 9.7 inches was used. The following tests were used: reaction choice (RC), reaction to a moving object (RMO) and size test (ST). The results of the groups were compared using the nonparametric Rosenbaum test (Q), and the Pearson correlation coefficient (r) was determined. Results. RMO test results in group 2 were significantly better than those in group 1 (Q=12, p<0.01). A similar correlation was determined for RC (Q=14, p<0.01) and ST (Q=15, p<0.01). When analyzing the frequency of incorrect reactions in RMO, it was found that athletes in the 1st group lagged behind more often (Q=6, p<0.05). A comparison of groups 2 and 3 confirmed that senior athletes had better results in RC (Q=11, p<0.01). For all tests used, the best results of group 3 compared with group 1 was determined: for RMO Q=16, (p<0.01), for RC Q=22, (p<0.01), for ST Q=20, (p<0.01). Senior athletes often had an anticipatory reaction in RMO, (Q=7, p<0.05). Significant correlations (p<0.05) were determined in group 1 between age and frequencies of anticipatory (r=-0.57) and lagging reactions (r=0.57), RMO and RC (r=0.63), RC and frequencies of anticipatory reactions (r=0.57) and lagging reactions (r=-0.57). In group 3, significant correlations were determined between age and RC (r=-0.59), RMO and RC (r=0.76), age and ST (r=-0.53), RMO and ST (r=0.65), RC and ST (r =0.79).  Conclusions. A change in the speed of reaction to various stimuli of taekwondo athletes of different ages has been confirmed. An increase in age and training experience improves the reaction rate. This dependence is most pronounced when comparing junior and senior athletes. The determined correlations between all tests used also reflect the improvement in the psychophysiological state of the athletes with increasing age. The tests used are characterized by accessibility, specificity, informativeness and financial feasibility. The results obtained allow for recommending their use in monitoring the state of martial arts athletes.

Purpose: to conduct a comparative analysis of psychomotor abilities in athletes of cyclic sports (short track), martial arts (karate, taekwondo) and esports (CS:GO). Materials, participants and methods: The study involved athletes of percussion martial arts (n=10, age 18,9±0,12, candidates for master of sports), elite players of semi-professional CS:GO teams (n=10, age 19,2±0,50), short track speed skaters (n=10, age 19±0,09, masters of sports). The choice reaction time, the frequency of local movements (60-second tapping test), and the reaction time to a change in the size of the object (Size-test) were determined. Research results. Esports athletes have the best reaction time of choice and tapping test compared to other athletes. The wrestlers showed the best reaction to distinguishing the size of an object in the Size-Test. Skaters have high rates of complex reaction time and frequency of movements. The duration of the tapping test has a likely inverse relationship with the frequency of tapping. Conclusions. It was found that esports athletes have a significantly better choice reaction time (p<0,05) than martial arts athletes. The results of short track skaters do not have significant differences with martial arts and esports athletes (p>0.05). The results of the tapping test in terms of the total number of movements and the average number for 5 s in esports athletes tend to be higher compared to short track speed skaters and martial arts athletes. The fastest response time to a change in the size of an object in the Size-test was shown by martial arts athletes, the slowest by short-track skaters. This reflects the trend towards better results of this type of reaction in martial arts athletes compared to short track speed skaters and esports athletes.

Study purpose. The study purpose was to determine changes in indicators of special physical preparedness and speed of attacking strokes in badminton players aged 10–11 under the influence of specially selected exercises. Materials and methods. The study participants were young badminton players aged 10–11 (12 boys), whose sports experience was 2-3 years. The study lasted 3 months and included: testing of special physical preparedness and assessment and analysis of the speed of attacking attacking strokes of young badminton players. Results. Analysis of the results of the study showed positive changes in the results of special physical preparedness, accuracy and speed of attacking strokes. The complex development of the speed-strength abilities of young badminton players was determined by the exercises of throwing a ball weighing 1 kg, triple long jump and jumping rope. This was manifested in the execution of attacking strokes from the place and in jumping and moving, but there was a significant increase in results in the triple jump and jumping rope. The development of speed endurance determined the 4-point center-to-center movement exercise, but the results did not change significantly over the course of the study. Accuracy indicators of attacking strokes significantly increased by an average of 2,58%. The results of the speed of attacking strokes also had a significant increase by an average of 29.41%. The use of complexes for training the accuracy of attacking strokes along with targets with a gradual complication of exercises increased the results of test exercises for accuracy and speed of execution. The indicators of the speed of attacking strokes on the left and on the right correlate with each other. The accuracy results of the right hand strokes along the line significantly correlate with right hand strokes along the diagonal and the triple long jump from a place. This indicates the connection of speed-strength abilities with the performance of attacking strokes by young badminton players. Indicators of a triple long jump from a place, jumping rope for 1 min. and throwing a ball weighing 1 kg are significantly correlated with each other, which indicates the complex development of the speed-strength abilities of young badminton players. Conclusions. The presented complexes of special preparatory exercises had a positive effect on changes in the indicators of special physical preparedness, accuracy and speed of the attacking strokes, which makes it possible to recommend them to 10–11-year-old badminton players in the training process.
