PURPOSE This study aims to help improve performance by comparing and analyzing the kinematic variables for each upper and lower extremities segment when two groups of players attack the national women’s fencing players in a match situation. METHODS This study divided the movement time, movement time ratio, Fente step length change, angle factor at each event, and velocity factor of the fencing point of a sword at each event into the Olympic medalists’ group (Group A) and the international competition winners group (Group B) during the fencing Marche Fente. An independent t-test was performed for each factor, and the results were compared. RESULTS As a result, the difference between the two groups in movement time was statistically significant in the front of the foot in the velocity factor. However, no statistical significance was found between the two groups in the front angle of the trunk, the elbow angle, and the knee angle. CONCLUSIONS This indicates that group A and group B are both outstanding players with the best performance, so they are similar in the details of the movements except for the very slight difference in time and velocity. Therefore, the average of the result values of the joint angle will be a feedback index for fencing beginners or education subjects who are now starting to fencing.
Purpose The purpose of this study was to investigate the effects of 3 weeks of fencing specific training on physical fitness in elite fencers. Methods Forty eight elite fencers participated in this program (Male= 24, Female= 24). Training program consists of dynamic stretching, step and agility training, and it was conducted with the general fencing practice during 3 weeks. Body composition and physical fitness (muscle strength/power, agility, anaerobic power and flexibility) were measured before and after training. Data were analyzed using IBM SPSS Statistics ver. 23.0 (IBM Co., Armonk, NY, USA). Paired t-test (pre vs. post) was used for comparison between groups. Results Muscle mass and body fat(%) were significantly changed after training in male group. Agility was significantly improved in change-step jump and reaction time after training both in male and female group. In Anaerobic power, peak power (relative power, absolute power) was significantly increased after training in female group. Flexibility was also significantly improved after training in left ankle ROM of female group. Conclusion Application of fencing specific training program focused on fencing movement seems to be effective on agility in both groups, muscle mass and body fat(%) in male group, and anaerobic power and flexibility in female group.
The purpose of this research is to investigate the factors affecting the performance capability of lunge movements by performing lunge movements which are commonly used as a method of instant physical movement in sports with a kinetic analysis including an EMG analysis. This research targeted 14 skilled fencers and made the subjects perform kick-lunges which allow them to go farthest from their positions and performed an analysis on such, applying a 3D motion analysis system and an EMG system. The subjects performed kick-lunges in two movements; one with a preliminary movement and the other without it and those are performed with both dominant leg and non-dominant leg. The result of this research is as follows. The lunges with a preliminary movement showed higher performance capability than those without it. Furthermore, as the level of skills gets higher, the length of lunges gets longer, and it seemed that a tactical mechanism shortening exercise performance times was used as a mechanism to control the impulse coming from such lengthened lunges. In addition, a difference appeared in mechanical factors such as moment and power in a dominant leg movement and it seemed to result from a difference in an functional capability using muscles.
Purpose The purpose of this study was to establish the differences of anticipating accuracy and confidence according to fencing expertise and spatial occlusion region. Methods For the purpose of this study, the anticipation ability of 6 high-level fencing players and 6 low-level fencing players were analyzed. All subjects performed the 60 tasks of anticipating the attack positions(thorax, thigh, toe) from observing the fencing video screen using spatial occlusion technique. The spatial occlusion technique was used in 6 particular body of opponent’s movement. For statistic analysis, data was analyzed through independent T-test measure. Moreover, Paired t-test were used as follow-up analysis. Results The results of the study were as follows: In terms of accuracy anticipation, the main effect of expertise was significantly different. Specifically, when the spatial occlusion technique was applied in head, left leg, arm, and a foil, the accuracy of anticipation was significantly different. Moreover, comparing with no-occlusion condition, anticipation accuracy decreased when spatial occlusion technique was applied in arm and foil. In terms of confidence, there was no significant difference between level of expertise. Conclusions In order to effectively anticipate the opponent’s movement in fencing sports, it is necessary to focus on the visual cues of arm/shoulder, and the foil. Especially, focusing on the foil movement might provide the core informations on anticipation ability.
PURPOSE This study aimed to analyze the difference between scores and loss of world-class fencing sabre players. METHODS A total of 78 match videos and 1969 points of international competition over 3 years were analyzed for the nine major competitors of the national fencing team (Males = 5, Females = 4). The characteristics of each skill, body section and location according to the score were analyzed by dividing them into male and female groups. Data were analyzed using IBM SPSS ver. 25.0. RESULTS First, in the situation analysis according to the men's sabre score, attack skills were the most common in the winning situation (447 points, 73%) and in the situation of losing points (389 points, 72%); however, the difference was not significant. In the analysis of the piste location according to the score, B4 was the most common appearing 254 times (41.5%) in the scoring situation and A4, 243 (45%) times in the losing situation, with a significant difference (p < 0.001). Second, in the situation analysis according to the women’s sabre score, 315 attacks (70.6%) were found in the winning situation and 277 (74.7%) in the losing situation; however, the difference was not significant. In the analysis of the scoring body part, the Sixte area scored the highest with 121 points (27.1%), and the arm area lost the most points with 105 points (28.3%); however, the difference was not significant. In the analysis of the piste location according to the score, A4 was the most common in, appearing 179 times (40.1%) in the scoring situation, and 182 times (48.8%) in the losing situation, with no significant difference at the p < 0.001 level. CONCLUSIONS In the men's game, there were many scored points in B4 and many lost points in A4. In the women's game, there were many scored points and lost points in A4; therefore, the difference in goals and losses according to the piste position was confirmed. These results suggest that it is possible to infer the game management patterns of world sabre players and the flow of world fencing.

Purpose The purpose of this study was to compare the official world records of UIPM in the last 3 years to find out the relationship between the score characteristics of fencing, swimming, equestrian, and laser-run events in the final rankings and to analyze the relative importance of each event. Methods For 3 years, from 2017 to 2019, a total of the data were collected, the final rankings, fencing conversion scores, swimming conversion scores, equestrian scores, and laser-run conversion scores for all male and female athletes who participated in the UIPM Level 1 World Cup and World Championships(1,197 finals and 2,173 qualifiers). The Multiple regression analysis was used to establish the relationship between the response(subjective) variable and the conversion score of the four explanatory(independent) variables. Results The results were compared by qualification (n = 2173) and final (n = 1197) by dividing into male (n = 1179) and female (n = 1591), and the fencing score was qualifications (male β= -.691, female β= -.533) and the finals (male β= -.632, female β= -.632), it showed the greatest influence in all. On the other hand, the swim score showed the lowest impact on both qualifications (male β=-. 021, female β=-.196) and finals (male β=-. 087, female β=-. 207). The fencing event plays a major role in passing the qualifiers and is a big variable for good performance in the finals. On the other hand, in the case of swimming scores, both men and women had the lowest impact on the final ranking, and there is a limit to the final performance of swimming scores in both qualifiers. Conclusion In conclusion, it is necessary to analyze and systemize the fencing skills of the world’s best athletes, including Korean athletes, to improve the Korean fencing athletes' performance, and through such scientific analysis, a system that enables fast and flexible responses to the upcoming Olympic. Additionally, even though the importance of all sports should be levelled due to the characteristics of modern pentathlon, relative importance is biased toward fencing and swimming events are neglected. Therefore, it is deemed necessary to conduct a follow-up study on whether the scoring system in modern pentathlon consists of a scoring system that supports the records of each event and the upper and lower scoring system.
Purpose The purpose of this study is to examine the location, rate, cause, and types of injuries according to the injured area by age and sports in female athletes. Methods The subject of the study was 426 female athletes who were registered as combat sports(Judo, Taekwondo, Fencing) athletes at the Korean Sports & Olympic Committee. We collected the data via online questionnaires, and conducted a frequency analysis using R statistics program. Results As a result, 51.4% of athletes experienced injuries in the past year, and the highest injury rate was shown in Taekwondo-University(0.43) during competition and Taekwondo-Professional(5.55) during training. The cause of injuries during competition was mainly due to 'as a result of me or the opponent's hittings, skills, or fouls' among internal factors, and 'recurrent injuries' among external factors. Among internal factors during training except for torso area and professional athletes, most of the injuries were also caused by ‘as a result of me or the opponent's hittings, skills, or fouls’ and ‘recurrent injuries’ among external factors. The frequency of injury was the highest in the lower extremity area across all age groups. The most frequently injured area, in the case of Judo, is skin-bleeding in the head, skin-bruise, muscle-inflammation, bone-fracture, spondylopathy(disc, stenosis, etc.) in the torso, muscle-inflammation in the upper extremity, ligament-sprain, rupture in the lower extremity. Taekwondo athletes had skin-bruise in the head, upper and lower extremities, and muscle-inflammation in the torso area, as the frequent injury cases, and Fencing athletes had all skin-bruise regardless of injuries. Conclusions The results of this study will be used to take measures for preventing injuries or to change training programs.
Purpose This study was to explore construct of fear and courage behavior overcoming the fear and relationship between fear and courage in competition. Methods Total 65 national athletes of combat sports(Judo, Boxing, Taekwondo, Fencing) responded to open questionnaire about fear and courage behavior in competition. The data was analyzed by triangle verification and content analysis. Results Firstly, the fear of combat sports athletes consisted of five factors, which were negative consequences, lack of preparation for a game, concerns of performing one’s best, expectation of significant others, and internalized ego threat. Secondly, courage behaviors to overcome fear were self-effort, self-suggestion, self-conviction, selfish self-regulation, social self-control, self-analysis, and acceptance of experience. Finally, there were the relationship between fear and courage in competition. Conclusion These results will contribute to provide useful information for combat sport athletes and coaches in different level to cope with competition fear.
The ACTN3 R577X polymorphism has been associated with an elite athletes status. Several studies have determined that the R allele is connected with power-oriented athletic performance, whereas the nonfunctional XX genotype may give some beneficial effect for endurance performance. The main aim of the study was to determine the possible interaction between the ACTN3 R577X polymorphism and an power-oriented athlete status in Korean elite athletes(wrestling 31, judo 13, boxing 16, fencing 6, cycle 16, ≤400m athlete 18). Each athletes performed a 30-second WAPtest with a resistance equal to 7.5% for male and 5% for female body weight. Genotyping for the ACTN3 R577X (rs1815739) polymorphism was performed using the TaqMan approach. The ACTN3 R577X genotypes exhibited a HardyWeinberg equilibrium distribution in our population. The relative and absolute average power results of the 30-second Wingate test did not differ significantly among the genotypes. However, the relative peak power result of the Wingate test was significantly higher in the R-allele- dominant model groups than in the XX group in male but not female athletes. These results suggest that the ACTN3 R allele is associated with the relative peak power during the Wingate test in male Korean elite athletes.
