Whole-Body Vibration Performance in Karate
Karate athletes strategically use lower-limb techniques in combat, with the roundhouse kick (mawashi geri) being highly effective in kumite. To quickly improve the technical performance before training or competitions, conditioning activities (CAs) are often utilized. Recently, Whole-Body Vibration (WBV) has emerged as a potential conditioning activity (CA). This study aimed to analyze the acute effects of WBV as a CA on the performance of the mawashi geri. The sample included sixteen male karate athletes. The study had a familiarization and two experimental sessions: one with WBV and the other without (NWBV), conducted randomly and counterbalanced, each preceded and followed by a mawashi geri assessment on a force platform. During the CA intervention, the participants performed four sets of isometric half-squats on a vibration platform at a frequency of 26 Hz and an amplitude of 4 mm in the WBV condition, while the platform was off in the NWBV condition. A significant reduction in the mawashi geri attack phase time was observed under the WBV condition [pre: 0.31 ± 0.03 s; post: 0.30 ± 0.03 s] compared to the NWBV condition [pre: 0.31 ± 0.04 s; post: 0.32 ± 0.03 s] (p = 0.02). However, no differences were noted regarding the impact force or other kinetic variables between the conditions. Therefore, WBV did not increase the performance of the kinetic and kinematic variables of the mawashi geri in karate athletes, but it is possible that there is a positive effect on attack time, suggesting that further studies with different vibration protocol configurations would be beneficial.

Sensitivity to rewards and punishments in karate athletes: an examination of the temperamental characteristics and profile of karate competitors according to the revised reinforcement sensitivity theory
Background
The revised Reinforcement Sensitivity Theory (rRST) assumes the existence of three systems controlling motivation and behavior: the behavioral activation system (BAS), the behavioral inhibition system (BIS), and the fight-flight-freeze system (FFFS). This study aims to examine for the first time the features of BAS, BIS, and FFFS among karate players in comparison with athletes representing other sports disciplines (physical education students) and physically inactive people. The specific configuration of temperament traits and profiles characterizing karate players will also be found.
Methods
The cross-sectional study was performed among male karate athletes and control groups (physically active and inactive men). The study used the modified Reinforcement Sensitivity Questionnaire (rRSQ) to measure BAS, BIS, and FFFS.
Results
The ANOVA showed that both karate competitors KS and KK scored significantly higher in BAS than the sample of PI participants. In addition, KK athletes scored significantly lower in Freeze than in PI and KS groups. Research also suggests that KK athletes presented significantly lower overall scores in FFFS than PI individuals. Furthermore, the results of K-means cluster analysis indicated the existence of two distinct patterns of temperamental traits: (1) Cluster 1 suggests avoidance tendencies (high Flight and Freeze, and low BAS, BIS, and Fight levels); while (2) the Cluster 2 describes approach tendencies (high BIS, BAS and Fight scores, and low levels of Flight and Freeze). Significantly more KK athletes were included in Cluster 2 than in Cluster 1, compared to PI, PA, and KS samples.
Conclusions
The research indicates that individuals engaged in karate, particularly those practicing Kyokushin karate, tend to exhibit a heightened sensitivity to rewards (high BAS). This finding holds significance for coaches and sports instructors, suggesting that motivating karate athletes through incentives is more effective, while the use of punishment should be minimized during training. Additionally, the study proposes that the practice of Kyokushin karate has the potential to significantly diminish the freezing response in threatening situations and enhance overall fear management by reducing levels of the Fight-Flight-Freeze System (FFFS). Consequently, the Kyokushin karate style may be considered more advantageous than the Karate Shotokan (KS) style in these aspects, despite both styles contributing to the improvement of BAS. Given that a higher BAS is linked to positive emotions, optimism, and happiness, karate training emerges as a form of health intervention, acting as a preventive measure against mental disorders and promoting overall well-being.

Flexible Pressure Sensors for Integration into Karate Body Protector
The increasing interest in karate has also attracted the attention of researchers, especially in combining the equipment used by practitioners with technology to prevent injuries, improve technical skills and provide appropriate scoring. Contrary to the sport of taekwondo, the development of a smart body protector in the sport of karate is still a niche field to be researched. This study focused on developing piezoresistive, textile-based pressure sensors using piezoresistive film, conductive fabric as well as different bonding materials and methods. Primarily, small-scale sensors were produced using ultrasonic welding, hot press welding and oven curing. These were characterized using a universal testing machine and specific conditioning and data-acquisition hardware combined with custom processing software. Large-scale sensors were then manufactured to be placed inside the karate body protector and characterized using cyclic testing. The conditioning circuit allows flexible gain adjustment, and it was possible to obtain a stable signal with an output of up to 0.03 V/N, an adequate signal for the tested force range. The transfer function shows some drift over the cycles, in addition to the expected hysteresis and slight nonlinearity, which can be compensated for. Finally, the configuration with the best results was tested in real practice tests; during these tests the body protector was placed on a dummy as well as on a person. The results showed that the piezoresistive textile-based pressure sensor produced is able to detect and quantify the impact of even light punches, providing an unobtrusive means for performance monitoring and score calculation for competitive practice of this sport.

Improvement of special training of karatists for kumite competitions using Kata
Oriental martial arts has millions of fans around the world. Successfully develop and cultivate all styles of martial arts from Chinese Wushu to full contact Muetai, Kyokushinkai karate, and many others. Kyokushinkai Karate is one of the most popular types of martial arts, cultivated by more than 16 million people in 140 countries, which has a well-established training system, one of the elements of which is the development of specialized kata complexes. This is a formalized sequence of movements, combined on the principles of a duel with imaginary one or more opponents. The purpose of the study is to improve the special training of qualified Kyokushinkai karate athletes in the competitive discipline of Kumite with the use of kata complexes. The following research methods were used: theoretical analysis and generalization of scientific and methodological literature; sociological methods (questionnaires); pedagogical observation; pedagogical testing, pedagogical experiment; medical and biological methods, and methods of mathematical statistics. The priority of the executioner \"Sanchin\" and \"Tensho\" as elements of special training and the significance of their impact on the physical condition of the athlete. The author's technique of training process with the use of kata complexes is developed and introduced, for the directed influence on separate indicators of the level of development of special physical qualities and functional state of karate. As a result of the use of kata in the preparation of qualified karate for Kumite in the athletes of the experimental group, there were significant positive changes in the level of development of special physical qualities and speed and strength indicators when performing many shock combinations. There was a statistically significant (p <0.05) increase in power and time parameters of complex, multi-stroke combinations \"Shita Tsuki\" - \"Mavashi Tsuki\" - 25.8%, \"Shita Tsuki\" - \"Mavashi Tsuki\" - \"Mavashi Geri\" - 28.4%).

The Influence of Sport Practices on Body Composition, Maturation and Maximum Oxygen uptake in children and youth (La influencia de las prácticas deportivas en la composición corporal, la maduración y la absorción máxima de oxígeno en niños y jóvenes)
Systematic sport practice at younger ages positively influences body composition and maximum oxygen uptake (VO2max). On the other hand, its influence on maturation is still not consensual, and some studies claim a negative effect. Few studies have approached the differences in this influence according to different sport practices. The present study aims to analyse and compare the influence of karate and swimming practices, and the non-practice of sports, on body composition, VO2max and maturation in children and youth. Data were collected in 126 youth, 54 karate athletes, 36 swimming athletes and 36 participants with no sport practice (M=11.56±2.06 years). The type of sport practice had a different influence on body composition and VO2max, no negative influence was verified on maturation. In general, the sport practices revealed a positive influence in children and youth’s body composition. The karate practice provided significant lower body fat mass and higher lean mass in males. Swimming athletes revealed a significant higher VO2max compared to all other groups, while karate didn´t differed from no-practice group. The different influence of sport practices verified highlighted the importance of a multilateral development of children and youth by practising several sports. Resumen: La práctica deportiva sistemática a edades más tempranas influye positivamente en la composición corporal y la absorción máxima de oxígeno (VO2max). Por otro lado, su influencia en la maduración aún no es consensuada, y algunos estudios afirman un efecto negativo. Pocos estudios se han acercado a las diferencias en esta influencia según las distintas prácticas deportivas. El presente estudio tiene como objetivo analizar y comparar la influencia de las prácticas de kárate y natación, y la no práctica de deportes, sobre la composición corporal, el VO2máx y la maduración en niños y jóvenes. Los datos fueron recolectados en 126 jóvenes, 54 atletas de kárate, 36 atletas de natación y 36 participantes sin práctica deportiva (M = 11.56 ± 2.06 años). El tipo de práctica deportiva influyó de manera diferente en la composición corporal y el VO2max, no se verificó influencia negativa en la maduración. En general, las prácticas deportivas revelaron una influencia positiva en la composición corporal de niños y jóvenes. La práctica del karate proporcionó una masa grasa corporal significativamente más baja y una masa magra más alta en los hombres. Los atletas de natación revelaron un VO2max significativamente más alto en comparación con todos los demás grupos, mientras que el karate no difirió del grupo sin práctica. La diferente influencia de las prácticas deportivas verificada resaltó la importancia de un desarrollo multilateral de la niñez y la juventud a través de la práctica de varios deportes.
