Background and Study Aim.  To carry out a comparative analysis of indicators of short-term visual memory in athletes of cyclic sports (short track), martial arts (karate, taekwondo) and esports (CS:GO). Material and Methods. The study involved athletes of percussion martial arts (n=13, age 18.8±0.52, experienced athletes), elite players of semi-professional CS:GO teams (n=10, age 19.2±0.50), short track speed skaters (n=12, age 19.1±0.25, experienced athletes). Short-term visual memory was determined using a special program for tablet computers running iOS. Results. Certain trends have been established regarding the characteristics of the state of the body of elite athletes in martial arts, short track and esports in terms of averaged indicators. In terms of the short-term visual memory coefficient and the average percentage of errors, martial arts athletes showed the best result, and short trackers showed the worst result. The shortest average test duration was recorded for short trackers. At certain stages of the test, they dominated athletes of other specializations in terms of reaction time. However, the trend towards faster response was associated with a decrease in the accuracy of the selection, that is, a greater percentage of errors. Cyberathletes and martial arts athletes were characterized by better adaptive abilities than short track athletes. Conclusions. The specificity of sports activities of cyberathletes determined the best results of the most difficult stage of the test both in terms of speed and accuracy. This criterion can be recommended for esports selection and prediction. The control of the cognitive functions of athletes is expedient in the course of monitoring their physical condition and is a promising direction for predicting the reliability and success of competitive activity.
背景和研究目的。 对周期性运动(短道速滑)、武术(空手道、跆拳道)和电竞(CS:GO)运动员的短期视觉记忆指标进行比较分析。材料和方法。研究对象包括打击乐武术运动员(人数=13,年龄18.8±0.52,经验丰富的运动员)、半职业《CS:GO》战队精英玩家(人数=10,年龄19.2±0.50)、短道速滑运动员(人数=12,年龄19.1±0.25,经验丰富的运动员)。使用运行 iOS 系统的平板电脑专用程序测定短期视觉记忆。结果从平均指标来看,武术、短道速滑和电子竞技精英运动员的身体状态特征呈现出一定的趋势。在短期视觉记忆系数和平均错误率方面,武术运动员的结果最好,短跑运动员的结果最差。短跑运动员的平均测试时间最短。在测试的某些阶段,短跑运动员在反应时间方面超过了其他专业的运动员。然而,反应速度加快的同时,选择的准确性却降低了,也就是说,错误的比例增加了。与短道速滑运动员相比,网络运动员和武术运动员的适应能力更强。结论网络运动员体育活动的特殊性决定了他们在最难的测试阶段无论在速度还是准确性方面都能取得最佳成绩。这一标准可推荐用于电竞选拔和预测。在监测运动员身体状况的过程中,对运动员认知功能的控制是一种权宜之计,也是预测竞技活动可靠性和成功率的一个有前途的方向。

Background and Study Aim. The physical attributes of muscular strength and endurance are essential for wrestlers to perform successfully. For the development of these physical qualities, high intensity interval training (HIIT) using kettlebell strength exercises is appropriate. The purpose of this study was to develop a kettlebell HIIT program for wrestlers and evaluate the results on strength and endurance. Material and Methods. Eight freestyle wrestlers who participated in the Bulgarian Wrestling Championships (age: 22.0±2.17 years, wrestling experience: 9.9±2.80 years) were included in the study. Measurements included height, weight, 8 circumferences, 8 skinfolds, and BMI, body fat percentage (%BF), and skeletal muscle mass percentage (%SMM). The wrestlers engaged in an HIIT circuit that involved four rounds of 16 kg kettlebells and eight exercises, each lasting 20 seconds to complete and 10 seconds to recover between. Polar H7 was used to continually record heart rate (HR). At rest, before, immediately after, and 15 minutes after the HIIT, blood lactate concentration (La) was assessed. Each exercise's number of repetitions was noted. Results. The wrestlers' average height was 175.2±7.45 cm, their average weight was 85.1±13.38 kg, and their average BMI was 27.6 kg/m2. The SMM was 42.1±2.39%, and the BF was 10.3±3.98%. Heart rate (HR) exhibited a pattern of elevation from rest to warm-up and during circle 1 to 4, followed by a decrease 10 minutes after HIIT. Lactate levels (La) displayed an upward trend from rest to before HIIT, a significant increase after HIIT, and a decrease 15 minutes after HIIT. Conclusions. As shown by the fact that each wrestler's HR during the kettlebell HIIT was above 75% of HRmax and that La was above the anaerobic threshold (>4 mmol/L), the created kettlebell HIIT, when used 5 times per week for eight weeks as part of the wrestlers' training, can improve their endurance.
背景和研究目的。摔跤运动员要想取得好成绩,肌肉力量和耐力是必不可少的身体素质。为了发展这些身体素质,使用壶铃力量练习进行高强度间歇训练(HIIT)是合适的。本研究的目的是为摔跤运动员制定壶铃高强度间歇训练计划,并评估其对力量和耐力的影响。材料和方法。研究对象包括八名参加保加利亚摔跤锦标赛的自由式摔跤运动员(年龄:22.0±2.17 岁,摔跤经验:9.9±2.80 年)。测量项目包括身高、体重、8 个周长、8 个皮褶、体重指数(BMI)、体脂百分比(%BF)和骨骼肌质量百分比(%SMM)。摔跤运动员进行的 HIIT 循环训练包括四轮 16 公斤壶铃和八次练习,每次练习持续 20 秒,中间恢复 10 秒。Polar H7 用于持续记录心率(HR)。在休息时、HIIT 运动前、运动后和运动后 15 分钟,对血液乳酸浓度(La)进行评估。记录每次运动的重复次数。结果摔跤运动员的平均身高为 175.2±7.45 厘米,平均体重为 85.1±13.38 公斤,平均体重指数为 27.6 公斤/平方米。SMM为42.1±2.39%,BF为10.3±3.98%。心率(HR)呈现出从休息到热身以及在第 1 至第 4 圈期间升高,然后在 HIIT 结束后 10 分钟下降的模式。乳酸水平(La)从休息到 HIIT 前呈上升趋势,HIIT 后显著上升,HIIT 后 15 分钟下降。结论在壶铃 HIIT 期间,每位摔跤运动员的心率都高于最大心率的 75%,La 也高于无氧阈值(>4 mmol/L),由此可见,作为摔跤运动员训练的一部分,每周进行 5 次、每次持续 8 周的壶铃 HIIT 可以提高他们的耐力。

Background and Study Aim. Foot posture is an important determinant of a basketball player's performance. It influences their ability to generate power, maintain balance, and absorb shock. The aim of the current study was therefore to examine the association between foot posture and landing error score in recreational basketball players. Material and Methods. A cross-sectional study design was adopted. Fifty recreational basketball players from selected basketball clubs were chosen for the study. Their Foot Posture Index (FPI) and Landing Error Scores (LESS) were assessed. Nonparametric statistics, such as chi-square tests and the Mann-Whitney U test, were employed to examine the relationship between selected demographic variables and FPI and LESS scores. Additionally, assessed the difference in foot posture between the dominant and non-dominant legs. p-value less than 0.05 was considered significant. Results. Most participants exhibited normal foot posture, with no significant differences between the dominant and non-dominant legs, as assessed by FPI (p < 0.05). Additionally, an association was found between FPI and LESS scores, with 44% of participants showing a propensity for landing errors. The analysis revealed that a notable number of participants were categorized as 'poor' in LESS even with normal foot posture. This implies that landing errors are not only influenced by foot posture. Conclusions. There is an association between foot posture and the occurrence of landing errors in basketball players. This study emphasizes the need to thoroughly examine basketball players' FPI. It also underscores the importance of developing strategies aimed at helping them maintain optimal foot posture. These strategies can assist in avoiding landing errors, reducing the risk of injury, and promoting good health and well-being.
背景和研究目的。脚部姿势是决定篮球运动员表现的重要因素。它影响着运动员产生力量、保持平衡和吸收冲击的能力。因此,本研究旨在探讨休闲篮球运动员的脚部姿势与落地错误得分之间的关系。材料与方法采用横断面研究设计。从选定的篮球俱乐部中挑选了 50 名休闲篮球运动员进行研究。对他们的脚部姿势指数(FPI)和着地误差得分(LESS)进行评估。研究采用了非参数统计方法,如卡方检验和曼-惠特尼 U 检验,来检验选定人口统计学变量与 FPI 和 LESS 分数之间的关系。此外,还评估了优势腿和非优势腿之间的足部姿势差异。结果根据 FPI 评估,大多数参与者的足部姿势正常,优势腿和非优势腿之间无明显差异(p < 0.05)。此外,还发现 FPI 和 LESS 分数之间存在关联,44% 的参与者有着陆失误的倾向。分析显示,即使脚部姿势正常,仍有相当多的参与者在 LESS 中被归类为 "差"。这意味着着陆错误不仅受脚部姿势的影响。结论。篮球运动员的脚部姿势与着地错误的发生之间存在关联。这项研究强调了彻底检查篮球运动员 FPI 的必要性。它还强调了制定旨在帮助他们保持最佳脚部姿势的策略的重要性。这些策略有助于避免着地失误,降低受伤风险,促进身心健康。

Background and Study Aim. With the increasing popularity of freestyle wrestling, the scientific community is paying more attention to gender factors that may influence the performance and success of competitive activities. The aim of study to determine differences in performance indicators between male and female wrestlers in the Olympic Games 2021. Material and Methods. The study included 192 athletes, consisting of 96 male wrestlers and 96 female wrestlers. An analysis of match records and video footage was conducted for women's (n=113) and freestyle (n=114) wrestling at the 2021 Tokyo Olympic Games. The assessment of performance indicators utilized an expert evaluation method. Statistical analysis of the obtained data was carried out using licensed Excel spreadsheet software. For categorical data, results were expressed in absolute numbers and percentages. Results. Based on the analysis of competitive activities at the 2021 Olympic Games, 12 primary technical-tactical actions were identified. The most frequently employed actions were in the standing position: leg attacks, with male wrestlers performing it 35.8% of the time and female wrestlers 30.3%; in the ground position, male wrestlers employed gut wrench (7.6%), while female wrestlers used ankle lace (9.4%). It was found that male wrestlers and female wrestlers accumulated approximately the same number of points for their actions: male wrestlers (926 points) and female wrestlers (912 points). The effectiveness in the standing position was higher for male wrestlers (720 points) than for female wrestlers (621 points). In the ground positions, female wrestlers demonstrated better effectiveness (291 points) than male wrestlers (206 points). The number of points deducted for rule violations was significantly lower for female wrestlers (8 times) compared to male wrestlers (27 times). Time stoppages during challenge reviews were fewer for female wrestlers (7 times) compared to male wrestlers (18 times). Conclusions. The conducted research indicates differences in the performance indicators of freestyle wrestling between men and women. Male wrestlers employ more actions in the standing position (81.7%) than female wrestlers (70.7%). Correspondingly, female wrestlers execute more actions in the ground positions (29.3%) compared to male wrestlers (18.3%). The total number of actions performed is higher for male wrestlers (579) than for female wrestlers (518). Female wrestlers achieve more premature victories (32.7% of all matches) compared to male wrestlers (24.6%). The obtained results will assist coaches in better adapting to gender differences and developing specific training programs for athletes.

Background and Study Aim. The purpose of research is to test experimentally the effectiveness of the influence of game means on the dynamics of endurance development in 10-year-old boys who attend the sports section of Kyokushinkai karate. Material and Methods. Forty 10-year-old boys engaged in Kyokushinkai karate took part in the research. The children and their parents were informed about all peculiarities of the research and agreed to participate in the experiment. The following research methods were used to solve the tasks: analysis of scientific and methodological literature, pedagogical testing, and methods of mathematical statistics for processing research results. Results. Statistically significant changes in results occurred in the studied groups (p<0,001). The improvement of the level of endurance development in 10-year-old boys’ karate athletes in favor of EG is confirmed. The highest statistically significant changes in EG indicators (р<0.001) occurred in tests "Bent arm hang" (14.6%), "Push-ups" (11.8%), "Burpee" (11.8%). The average performance in 300 m run (8.6%) and in kicks "Mawashi geri chudan" with the right (left) foot slightly increased by 9.8% and 8.1%, respectively. There was no significant difference in the results of the test "Sit-ups in 1 min from the supine position" between EG and CG groups (1.1%, p>0.05). However, both groups showed a sufficiently confident increase in the level of local dynamic power endurance (EG – 11.6%, CG – 10.4% at p<0.001). Conclusions. The level of boys’ endurance at the initial stage of the pedagogical experiment corresponds to proper age norms. According to most results, 36% of boys are classified as of average level, 16.5% as above average, 17% as high. The rest of the indicators were distributed between below average and low levels, 12% and 18.5%, respectively. A significant lag was found in terms of general endurance (300 m run test). The dynamics of the obtained data testified to the effectiveness of the developed, tested, and implemented physical education methodology of endurance development in 10-year-old boys’ karate athletes with outdoor games. Because of application of game load (5 games, 3 repetitions with rest intervals of 20 s) there was a statistically significant increase in endurance (р<0.001).

Background and Study Aim. It is increasingly important to know the influence of age characteristics on the development of motor skills necessary for gymnastics. Currently, this influence is taken into consideration in the training of young female gymnasts. This study aims to determine the anthropometric indices impact on static and dynamic balance parameters in young female gymnasts. Material and Methods. A group of 24 young gymnasts, from the Arad Municipal Sports Club of Romania, participated in this study.  The athletes, aged 6-10 years, were divided into two groups: G1 (6-8 years, n=17) and G2 (9-10 years, n=7). Anthropometric indices were measured by means of Tanita scale. The following indices were monitored: Height (cm), Weight (kg), FATP (%), FATM (kg), FFM (kg), BMI (kg/m2). Balance was evaluated with the Sensamove MiniBoard platform. There were used tests as follows: Static Bipedal Balance (SBB), Lateral Bipedal Balance (LBB) and Vertical Bipedal Balance (VBB). Measured parameters: performance (%); front and back inside (LBB, %); left and right inside (VBB, %); front and back avg. deviation (grade); left and right avg. deviation (degrees). The influence of anthropometric indices on balance parameters was determined using Pearson correlation coefficient. Results. The comparative analysis between groups highlights: average age; relation between weight and height; values of body composition indices. The comparative analysis shows better performances by 2.23% in G1 at SBB and values smaller by 0.35 degrees at average vertical deviations. LBB has better performances in G1 by 10.05% and higher values by 1.79% at keeping inside the vertical space. There is a smaller difference between Confidence Limit of Mean (CLM). As for VBB, the performances are better by 0.41% in G2, keeping inside the space to the left in G1 and to the right in G2. The correlation analysis regarding SB reveals 20% strong connections, 83.3% positive connections with performance and 45.8% negative ones with average deviations in G1. The following were noticed in G2: lack of strong connections, 33.3% positive connections and 25% negative influences. In terms of LBB, G1 has no strong connections, but it has 72.2% positive connections and 45.8% negative connections.  G2 is characterized as follows: 7.1% strong connections, absence of positive connections, 75% - negative connections. VBB presents the following values in G1: 28.6% - strong connections and 45.8% - negative connections. G2 has 9.5% - strong connections, 94.4% - positive connections and 75% - negative ones. Conclusions. By determining the anthropometric indices, the age characteristics of female gymnasts were highlighted. The comparative analysis results of balance parameters reveal better performances and lower values at the average vertical and lateral deviations. Comparing the relationships between anthropometric indices and balance parameters reveals strong connections. It also shows the weight of positive and

Background and Study Aim. In the context of the growing importance of strength training, the analysis of the impact of strength loads on muscle hypertrophy becomes increasingly significant. Therefore, it is critical to comprehend both the effects of strength training on stimulating muscle growth and the potential ramifications. This study aimed to systematically analyze and collate the existing scientific evidence on the effects of weight training on muscle hypertrophy. Material and Methods. The research method involved the source selection of relevant studies from various databases, with predefined inclusion criteria. A thorough literature search was conducted, followed by data extraction focusing on study design, subject population, type of weight training, duration, and outcome measures of muscle hypertrophy. Databases such as PubMed, Google Scholar and Scopus were the primary sources of literature searches. Results. The results of this systematic review indicated evidence supporting the positive effect of weight training on muscle hypertrophy in most of the studies included. However, some studies produced controversial findings or even showed no significant impact. Factors such as variations in exercise type, intensity, and frequency also influence the outcome of weight training on muscle growth. Conclusions. While weight training has the potential to stimulate muscle hypertrophy, its effects may vary based on various factors. Therefore, selecting the correct type of exercise, setting the appropriate intensity, and planning the frequency of activity is essential in achieving optimal results. This study has strong relevance in fostering effective and safe exercise programs.It can also serve as a basis for further research in exploring other factors that may influence weight training-induced muscle hypertrophy outcomes.

Background and Study Aim. The significance of analyzing statistical indicators is paramount, as they provide valuable insights into the distinguishing performance factors of teams. The purpose of this study: 1)  to identify statistically significant differences between relevant performance factors among winning, drawing, and losing teams in the 2022 Football World Cup in Qatar; 2) explore indicators that are most strongly associated with the game results in this tournament. Material and Methods. A total of 64 matches and 32 participating teams were analyzed. The variables included in the research were: total shots, shots on target, shots off target, effectiveness, passes, passes completed, crosses, crosses against, offsides committed, offsides received, fouls received, ball possession, fouls committed, corners, corners against, yellow cards and red cards. The results are extracted from the official FIFA website. The Analysis of Variance (ANOVA) and the ordinal logistic regression with elastic net were used for data calculation. Results. The results indicate that winning teams have statistically significantly higher mean values of variables related to goals scored: total shots (p < 0.05), shots on target (p < 0.01), and effectiveness (p < 0.01). According to the information-based model selection criteria AIC (Akaike information criterion) and BIC (Bayesian information criterion) effectiveness and shots on target are the most important variables regarding game results. They, along with corners, are best associated with successful teams. In contrast, crosses, ball possession, corners against, and yellow cards are associated with less successful teams. Results suggest that teams with high ball possession and large number of crosses, but fewer shots on target, have weaker results than teams with more shots on target and less ball possession. Conclusions. The study underscores the significance of certain performance indicators, such as total shots, shots on target, and effectiveness, in predicting a team's success. These findings provide valuable insights for coaches and teams to focus on specific aspects of their game to enhance their chances of winning. Additionally, understanding the impact of variables like ball possession, crosses, corners, and yellow cards emphasizes the importance of a well-rounded strategy for achieving success in international football tournaments.
背景和研究目的。对统计指标进行分析意义重大,因为这些指标能为了解团队的显著绩效因素提供有价值的见解。本研究的目的是1) 找出在 2022 年卡塔尔世界杯足球赛中获胜球队、平局球队和失利球队的相关表现因素之间在统计学上的显著差异;2) 探索与本届赛事比赛结果最密切相关的指标。材料与方法。共分析了 64 场比赛和 32 支参赛球队。研究变量包括:射门总数、射正次数、射偏次数、射门效率、传球次数、完成传球次数、传球次数、传球失误、越位、越位成功、犯规、控球率、犯规次数、角球、角球失误、黄牌和红牌。结果摘自国际足联官方网站。数据计算采用方差分析(ANOVA)和带弹性网的序数逻辑回归。结果显示结果表明,在与进球有关的变量中,获胜球队的平均值在统计上明显更高:总射门数(P < 0.05)、射正次数(P < 0.01)和效率(P < 0.01)。根据基于信息的模型选择标准 AIC(阿凯克信息准则)和 BIC(贝叶斯信息准则),有效性和射正次数是影响比赛结果的最重要变量。它们与角球一起与成功的球队联系在一起。相比之下,传中、控球、角球和黄牌则与不太成功的球队有关。结果表明,控球率高、传球次数多但射门次数少的球队比射门次数多但控球率低的球队成绩更差。结论。这项研究强调了某些成绩指标(如射门总数、射正次数和效率)在预测球队成功方面的重要性。这些研究结果为教练和球队提供了宝贵的见解,使他们能够专注于比赛的特定方面,从而提高获胜的机会。此外,了解控球率、传球、角球和黄牌等变量的影响,也强调了在国际足球赛事中采取全面策略取得成功的重要性。
