Observational analysis of technical-tactical performance in initiation to combat in karate
International Journal of Performance Analysis in Sport
In training karate, sports initiation through combat or kumite is becoming more and more relevant. The objective of the present work, carried out using an observational methodology, consists of analysing the technical-tactical performance in the initiation to kumite of karate. The observational sample is made up of 61 data packets, generated by 37 competitors, suitable for combat, in 40 combats. The records have been made using the LINCE software. The quality of the data has been guaranteed through inter-observer agreement and within the generalisability theory. A lag sequential analysis has been carried out in a complementary manner, using GSEQ5 software, and a second analysis was performed for the detection of T-patterns, using the THEME software, Edu6 version. The results obtained have made it possible to characterise the offensive technical action executed whether with the fist or leg, the laterality related to the guard that supports the action and the segment with which it is performed, the area of the body to which the technique is directed, and the efficiency obtained. This work is a relevant starting point in the longitudinal programming of formative karate.

The aim of this study was to define the time-motion (i.e., fighting, preparatory and breaking activity), technical (i.e., attack, timed-attack, counterattack, blocking and grasps) and tactical (i.e., upper limb, lower-limb, combination and throwing) profiles of the senior top-level karate competition played under the most recent rules of the International Karate Federation in relation to gender, match outcome and weight categories. Time-motion, tactical actions and technical executions were investigated of senior karatekas (n = 60) during the Karate World Championship. The referee's decisions caused an overall activity-to-break ratio of ~1:1.5 with a significant difference (P = 0.025) between karateka's weight categories (light = 1:1.5; middle = 1:2 and heavy = 1:1). High-intensity actions (i.e., attack and defensive actions performed quickly and powerfully) were higher in male compared to female athletes. Top-level karatekas used upper limb techniques more than lower limb o...

The aim of the present study was to identify the most used techniques by medalists and defeated athletes during the Brazilian Shotokan Karate Championship of 2017. Eleven fights involving thirteen athletes (28.5±3.7yrs.) who competed in the category “up to 65 Kg 1st KYU” were investigated. Analysis were conducted by six specialists through the observation and register technique using the tactical and technical spreadsheet Scout Karate. The Anova test was used to compare actions and techniques mostly used. The Chi-square test for independent samples was used to verify the existence of significant differences among the techniques used by the winning and defeated athletes (p<0.05). Results show that the most frequent attack during fights was the “Mawashi geri”, 26.3±1.5 times, followed by “Gyaku zuki” with 19.5±2.0 times (p<0.01). The most visualized tactical action during combats was the attack with 47.5±5.5 times (p<0.01). “Mawashi geri” was the mostly used attack (p=0.01) p...
Comparisons: Technical-Tactical and Time-Motion Analysis of Mixed Martial Arts by Outcomes
Journal of Strength and Conditioning Research, 2016
The aim of this study was to compare time-motion and technical-tactical analysis between paired outcomes and rounds of Mixed Martial Arts (MMA) matches. The sample consisted of 645 rounds of MMA competition paired by outcomes (1 st round, winners n=215 and losers n=215; 2 nd round, winners n=215 and losers n=215; 3 rd round, winners n=215 and losers n=215). The time-motion variables were categorized into low or high intensity, stand-up or groundwork situations. Stand-up techniques were analyzed by observing total strikes to the head and body, and takedowns. The actions on the ground were analyzed by observing submission activity, including successful choking and joint locking actions, as well as positional improvements, including advances to the mount, half guard, side and back positions. Chi-squared and Wilcoxon tests were conducted with a significance level of p≤0.05. Results showed that winners had higher values for total strikes and submissions in all rounds, as well as positional improvements, over losers. The standing combat with low intensity comparisons presented differences between the rounds 1 st , with a median of
Technical and Tactical Discriminatory Factors Between Winners and Defeated Elite Karate Athletes
International Journal of Sports Physiology and Performance, 2019
Purpose: To assess the technical and tactical demands of elite karate athletes in relation to 3 match sequences (ie, advantage, disadvantage, and drawing) and match outcome (ie, win/defeat). Methods: One hundred twenty elite seniors’ (60 men and 60 women) World Karate Federation combats were analyzed during 2 World Championships (2012 and 2014). Specific karate attributes (strategy, technique, tactic, target, and effectiveness) were evaluated and classified into 3 sequences: advantage, disadvantage, and drawing. Results: Karatekas performed more combination techniques in disadvantage sequences than in drawing sequences (P = .011). A higher number of timed-attack actions were reported during advantage sequences than during drawing sequences (P = .048). Winners of the whole combat had higher lower-limb technique rate (1.0 [0.9] vs 0.1 [0.3]; P = .044) and less rate of timed attack (0.3 [0.5] vs 0.6 [1.0]; P = .030) than defeated karatekas during advantage and drawing sequences, respec...
Tactical Performance Analysis of Malaysian Youth Karate Exponents
2020
The aim of this study was to analyse the tactical performance of youth karate exponents during the Malaysia Games, 2018. A total of 104 kumite matches, consisted of 52 men and 52 women were recorded during the games and analysed the frequency of attacking and defending using Longomatch® software. Non parametric Kruskal Wallis statistical analysis was used to compare the effectiveness of attacking and defensive by gender and performance of successful and unsuccessful athletes. The findings of this study showed that the male athletes were more effective in attacking than females. However, no differences by gender in the effectiveness of defending. This study also found that successful exponents were more effective in attacking for male and defending for both gender compared to unsuccessful athletes.
Validity of the test in two-hand successive attack techniques with top karate athletes
Almost in all modern sports, the level of adopted motor movements and specific techniques is one of the most important and decisive factors in coping with complex sports tasks and achieving sports results. Empirically, sports skills and adopted motor movements in specific techniques reach a high level of performance. Due to this fact, these movements are rational, precise and efficient in sports battles. Karate sport consists of numerous groups of techniques, and hand and leg strikes belong to the most dominant group. The dominance of these techniques is reflected in the fact that they are the single scoring techniques, and they are the only ones to be evaluated in the scoring balance when deciding on the battle winner. The topic and goals of this research are based on the present knowledge and arguments, and they refer to the newly constructed motor test of situational motor space with top karate athletes, both juniors and seniors, and establishment of its measuring characteristics. The research was conducted with 34 karate athletes, members of the senior national team of Macedonia. The sample of respondents was defined as an intended sample drawn from the population of male karate athletes. The obtained results are pointing towards the existence of the tests satisfactory measurement characteristics’, or factor validity, high level of sensitivity and very high coefficient of reliability (Cronbach α = .934 I Spearman-Brown = .935) and also high inter correlation coefficient which are pointing towards the fact that the eventual error during the measuring process is very small and insignificant.

This paper describes the effectiveness of technical-tactical actions performed during a tournament. A total of 14,145 actions of the 2012 London Olympic Games were analysed. Differences emerged in the use of tactics, techniques, zones, legs and guard to score. Regarding tactics, anticipatory counterattacks were the most effective for scoring one and three points. Circular techniques were the most effective for scoring one point, linear to score three points, and spin techniques to score two and four points. Actions to the chest results in a score of one to two points and actions to the head in a score of three to four points. The rear leg was more effective in scoring one, two and four points. A close guard was more effective for scoring two points. It is suggested that coaches and athletes pursue training in the aforementioned technical-tactical actions according to the score they desire to obtain during bouts.
