Background and Study Aim. Tactics is one of the basic terms underlying the management of competitive activities of athletes. In freestyle wrestling, the participation tactics of athletes in the competition system is covered fragmentally and needs proper justification. The purpose of the study was to determine the features of the participation tactics of elite athletes in the competition system in freestyle wrestling during 2013-2016 Olympic cycle. Materials and Methods. This study analyzes the dynamics of performances and results of 24 elite freestyle wrestlers who won gold, silver and bronze medals at the Games of XXXI Olympiad 2016 in Rio de Janeiro in different weight categories (four athletes in each of six weight categories). To do this, we used athletes’ individual profiles on the United World Wrestling. Used an expert assessment devoted to the issues of tactics and tactical training. The experts (n = 8) were well educated (3 among them held Ph.D. diplomas) and experienced – 2 coaches of Ukrainian national team, and 1 athlete–national team’s member. On average, experts had almost 10 years of experience in training wrestlers of different ages. The results were processed using Microsoft Excel software. Results. The volume of competition practice of elite athletes during 2013-2016 changed in each season. In the 2013 season, the average group number of competitions in which athletes participated was 3.84 ± 2.06, in 2014 – 3.50 ± 1.79. In the 2015 season, those indicators were the highest – 4.17 ± 1.87, but in 2016 they decreased to 3.71 ± 1.52. The participation tactics in the competition system in freestyle wrestling during the season and the four-year cycle differed depending on the dynamics of sports results. Four types of tactics used by the elite athletes in freestyle wrestling in 2013-2016 were identified: leadership holding, gradual improving of results, combined, leadership returning. It was found that during 2013-2016, most athletes (58.33-79.17%) used a variety of tactics that involved performances in one Olympic weight category. In 2014 and 2015, some athletes (20.83 and 25.00%, respectively) used different options in other weight categories, choosing one of them as a priority and one or two – as additional. Conclusions. There are four types of participation tactics in the competition system in freestyle wrestling. In 2013-2016 Olympic cycle they included leadership holding, gradual increase of results, combined, leadership return. The main differences between types of tactics are the volume of competition practice, the dynamics of results, the choice of weight category. The most relevant was the type of tactics with performances exclusively in the Olympic weight category during four seasons.

The aim of this study was to determine aerobic fitness through the VO2max treadmill test of elite Bulgarian taekwondo players with international results, and to determine whether the aerobic system had an effect upon the sports result in taekwondo. Fourteen elite taekwondo athletes, members of the Bulgarian national team (8 male and 6 female) were tested using a continuous progressive treadmill test. Physiological characteristics such as maximal oxygen uptake(VO2max), blood lactate and heart rate were measured. The male athletes recorded 58.2±3.4 ml kg–1 min–1 and the female 46.0±2.8 ml kg–1 min–1. The lactate level reached its highest at the 6’ after the VO2max with results for the males of 11.5±3.7 (mmol l-1) and 9.9±4.1 (mmol l-1) for the females respectively. A comparison between our results, regarding VO2max and previously reported was made using the One-way Anova for independent samples. It showed no significant difference between the male subjects (58.2±3.4 versus 60.7±3.3 ml kg(-1) min(-1), p>.05) and significant difference between the female ones (46.0±2.8 versus 49.8±2.8 ml kg(-1) min(-1), p<.05). Investigated also was the number of kicks executed by the winner of -49 kg weight category and her direct opponents during the 2019 Grand Prix Sofia. It was discovered that the winner kicked an average of 86.25 times per match and her kicks during the Grand Prix Sofia accumulated to 390 in total. It is our conclusion that the aerobic fitness does not play a significant role in taekwondo.

One of the main goals of sport psychology is to identify those psychological factors that are relevant for sport performance as well as possibilities of their development. The aim of the study was to determine whether the set of specific psychological characteristics [generalized self-efficacy, time perspective, emotional intelligence (EI), general achievement motivation, and personality dimensions] makes the distinction between athletes based on their (non)-participation in the senior national team, that is, their belonging to the subsample of elite or non-elite athletes depending on this criterion. According to the group centroids it can be said that elite athletes are characterized by a positive high score in self-efficacy, emotionality, present fatalistic time perspective, past positive time perspective, and openness to experience. They are also characterized by low past negative time perspective, emotional competence, and future time perspective. Non-elite athletes have the opposite traits. The results have been discussed in the context of their application in the process of talent selection and development in sport as well as the development of life skills in athletes.

Abstract Background: Although research on balance skills and personality were explored in the field of sports science, little is known about the relationship between the two phenomena. This study aims to investigate the association of postural balance with traits of personality and temperament. The differences between elite athletes, football players, and the control sample will also be examined. Methods: Participants in the case-control study were 73 people, aged between 16 and 30 years old (M = 21.29, SD = 2.47), including 59% of men. Three samples of participants consisted of Elite Athletes (AE, n = 17, 23.29%) of the Polish National Team; Football Players (FP, n = 32, 43.84%); and Control Sample (CS, n = 24, 32.88%). Postural control was assessed on a force platform (Type 9286AA, Kistler Instrument AG, Winterthur, Switzerland) with a sampling frequency of 100 Hz. The center of pressure (COP) parameters was measured during 20 seconds in both conditions eye open, and eye closed, in both directions anterior-posterior (AP) and medial-lateral (ML). The COP parameters include standard deviation (SD), mean range (RA), mean velocity (MV), and entropy (SE). The NEO-FFI questionnaire was used to assess Big-Five personality traits, whereas the FCB-TI was used to measure temperament traits. Results: One-way ANOVA revealed that the EA and CS groups were more stable in ML direction than the FP group. In the AP direction, the athletes from the EA group were more stable than the CS group. Nor personality, neither temperament did not differentiate the three groups of participants, beside agreeableness, which was significantly lower in both EA and FP groups. Openness to experiences is positively associated with COP parameters, as it was shown in regression analysis. All COP parameters can explain for about 40% of openness variability. Conclusions: The results of this study showed that EA and CS have better stability than footballers in both ML and AP direction. Openness seems to be related to postural balance skills.

Team handball matches place diverse physical demands on players, which may result in fatigue and decreased activity levels. However, previous speed-based methods of quantifying player activity may not be sensitive for capturing short-lasting team-handball-specific movements.Purpose:To examine activity profiles of a women’s team handball team and individual player profiles, using inertial measurement units.Methods:Match data were obtained from 1 women’s national team in 9 international matches (N = 85 individual player samples), using the Catapult OptimEye S5. PlayerLoad/min was used as a measure of intensity in 5- and 10-min periods. Team profiles were presented as relative to the player’s match means, and individual profiles were presented as relative to the mean of the 5-min periods with >60% field time.Results:A high initial intensity was observed for team profiles and for players with ≥2 consecutive periods of play. Substantial declines in PlayerLoad/min were observed throughout matches for the team and for players with several consecutive periods of field time. These trends were found for all positional categories. Intensity increased substantially in the final 5 min of the first half for team profiles. Activity levels were substantially lower in the 5 min after a player’s most intense period and were partly restored in the subsequent 5-min period.Discussion:Possible explanations for the observed declines in activity profiles for the team and individual players include fatigue, situational factors, and pacing. However, underlying mechanisms were not accounted for, and these assumptions are therefore based on previous team-sport studies.

Context The combination of extensive weight loss and inadequate nutritional strategies used to lose weight rapidly for competition in weight-category sports may negatively affect athletic performance and health. Objective To explore the reasoning of elite combat-sport athletes about rapid weight loss and regaining of weight before competitions. Design Qualitative study. Setting With grounded theory as a theoretical framework, we employed a cross-examinational approach including interviews, observations, and Internet sources. Sports observations were obtained at competitions and statements by combat-sport athletes were collected on the Internet. Patients or Other Participants Participants in the interviews were 14 Swedish national team athletes (9 men, 5 women; age range, 18 to 36 years) in 3 Olympic combat sports (wrestling, judo, and taekwondo). Data Collection and Analysis Semistructured interviews with 14 athletes from the Swedish national teams in wrestling, judo, and taekwondo were conducted at a location of each participant's choice. The field observations were conducted at European competitions in these 3 sports. In addition, interviews and statements made by athletes in combat sports were collected on the Internet. Results Positive aspects of weight regulation other than gaining physical advantage emerged from the data during the analysis: sport identity, mental diversion, and mental advantage. Together and individually, these categories point toward the positive aspects of weight regulation experienced by the athletes. Practicing weight regulation mediates a self-image of being “a real athlete.” Weight regulation is also considered mentally important as a part of the precompetition preparation, serving as a coping strategy by creating a feeling of increased focus and commitment. Moreover, a mental advantage relative to one's opponents can be gained through the practice of weight regulation. Conclusions Weight regulation has mentally important functions extending beyond the common notion that combat-sport athletes reduce their weight merely to gain a physical edge over their opponents.

Energy And Nutrient Intake

This study examines the degree of under-reporting of energy intake by elite, female gymnasts, and the impact this predicted under-reporting has on associated macro and micro nutrient intake. Twenty-eight female U.S. national team artistic gymnasts participated in the study. Dietary intake was assessed using 3-day food records, and the degree of under-reporting was predicted from the ratio of reported energy intake (EI) to predicted basal metabolic rate (BMRestd), using the standards described by Goldberg et al. (10). Sixty-one percent of the subjects had an EI/BMRestd ratio of < 1.44, and were classified as under-reporters. The under-reporters had higher BMIs and percent body fat, and lower reported total energy intakes than the adequate energy reporters. Additionally, under-reporting of energy intake had a significant impact on reported micro nutrient intake. The under-reporting of energy intake seen in these subjects has an impact on the reported intake of macro and micro nutrients that can influence the interpretation of the nutritional status of these athletes and the strategy for nutrition intervention. Therefore, when assessing dietary intakes of elite gymnasts, some means of determining the accuracy of the reported energy and nutrient intake should be employed to more accurately identify the true nutritional problems experienced by these elite athletes.

Attention has been theorized as a system comprising three networks that can be estimated reliably by the attention network test (ANT); the three networks are defined as alerting, orienting, and conflict control. The present study aims to identify the attention networks that are crucial for elite shooting and archery athletes and to examine whether mindfulness training can improve elite athletes' attention networks. We compared the performances in ANT between 62 elite athletes (27 F/35 M, 23.66 ± 4.95 years) from the Chinese national team of shooting and archery and 49 athletes (19 F/30 M, 19.53 ± 3.38 years) from a provincial team in China. The results indicate three well-functioned attention networks in both groups, but elite athletes in the national team responded faster overall than athletes in the provincial team (Diff = 28.84 ms, p = 0.006). The 62 elite athletes in the national team then received mindfulness training with varied periods ranging from 5 to 8 weeks, after which the ANT was re-administered. After mindfulness training, the elite athletes improved in orienting (Diffspatial = 10.02 ms, p = 0.018) and conflict control networks (Diffincon = 12.01 ms, p = 0.019) compared with their pre-training performances. These results suggest that elite shooting and archery athletes in the national team are more efficient in all three attention networks, which means that they are able to reach the alerting state faster, make better use of environmental information, and suppress interference from distractors more efficiently. Moreover, the orienting and conflict control networks of the elite shooting and archery athletes can be improved by mindfulness training. We conclude that mindfulness practice should be considered as a useful addition to daily training for shooting and archery athletes.

Abstract The aim of the paper is to widen knowledge about motivation of elite, recreational athletes and non-athletes. Participants from the elite athletes group (n = 35, 16.7 ± .70 years old) were football players of the Slovak national team. Recreational athletes (n = 31, 16.8 ± .80 years old) and non-athletes (n = 29, 15.7 ± .60 years old) are visiting Grammar School in Zvolen. D-M-V standardized questionnaire was used to determine performance motivation. The Kolmogorov-Smirnov's test disconfirmed the null hypothesis on the normality of data. We used the non-parametric Kruskal-Wallis and Mann-Whitney U tests to determine the statistical significance of the differences. The results showed that there were significant (p .0.01) differences with large effect size (η2 ≥ .14) in all the three (the performance motives scale, the anxiety inhibiting performance scale and the anxiety supporting performance scale) dimensions among the research groups. The motivation of elite athletes is significantly higher (p = .048; r = .25) compared to the recreational athletes. Also, compared to the non-athletes, the level of performance motivation is significantly higher (p = .002; r = .51) in the elite athletes. Based on the results of the study we can formulate the statement that the level of performance motivation is contingent on the level of sport activity.

The objective of the study was to explore the status of usage of complementary and alternative medicine (CAM) among Korean elite athletes. A survey was emailed to all Korean national sports federations recognized by the International Olympic Committee and the Olympic Council of Asia. A total of 705 Korean elite athletes participated in this study. The athletes had to be any of the following to participate in this survey: elite intercollegiate athletes, professional athletes, and national team athletes. 83.3% of the participants stated that they have previously experienced Korean medicine (KM). Compared to the general population in Korea, athletes had more experience (general population = 73.8%). The participants without experience mentioned that they either did not need any KM treatments (39.8%) or lacked information (39.8%) regarding KM treatments. The primary reason for the utilization of KM was the effectiveness of treatments. Therefore, 70.8% of the participants have mentioned recommending KM to others. Generally, athletes are worrisome that the consumption of herbal medicine may not be doping-free; however, it is vital to note that 62% of the participants expressed that prescribed herbal medicine is safe. Overall, this research demonstrates a high prevalence of KM usage by intercollegiate, professional, and national team athletes in Korea. Hence, this study’s results may serve as the foundation in future research directions for promoting KM among Korean elite athletes.
