Objective: The aim of this study was to compare the radial bone strength, sitting balance ability and global self-esteem of wheelchair martial arts practitioners and healthy control participants. Design: Cross-sectional study. Methods: Nine wheelchair martial art practitioners with physical disabilities and 28 able-bodied healthy individuals participated in the study. The bone strength of the distal radius was assessed using the Sunlight Mini-Omni Ultrasound Bone Sonometer; sitting balance was quantified using the modified functional reach test (with reference to a scale marked on the wall); and the self-administered Rosenberg self-esteem (RSE) scale was used to measure the global self-esteem of the participants. The velocity of the ultrasound wave (speed of sound, m/s) traveling through the outer surface of the radial bone was measured and was then converted into a T-score and a Z-score. These ultrasound T-score and Z-score that represent bone strength; the maximum forward reaching distance in sitting (cm) that represents sitting balance; and the RSE total self-esteem score that indicates global self-esteem were used for analysis. Results: The results revealed that there were no statistically significant between-group differences for radial bone-strength, maximum forward reaching distance, or self-esteem outcomes. Conclusions: The wheelchair martial arts practitioners had similar radial bone strength, sitting balance performance and self-esteem to able-bodied healthy persons. Our results imply that wheelchair martial arts might improve bone strength, postural control and self-esteem in adult wheelchair users. This new sport-wheelchair martial arts-might be an exercise option for people with physical disabilities.

The pivotal emphasis of the physical training for the security agents of the security headquarters in the North Korea is to inspire them with the defense physical training-centered ideology and the war spirit. Their special martial arts is the protectee-centered offensive arts rather than the self-centered arts. It puts emphasis on training black belt-holders in diverse martial arts rather than in a certain martial art. Thus, the physical training for security agents in the South Korea should be also developed into the ways to rear them as black belt-holders in diverse martial arts rather than to foster them as high grade-holders in a certain martial art. And also, professors majoring in security and physical science have to develop jointly the measures to improve the physical and mental agility and the basic physical strength to inspire rapid handling and perseverance, to develop the physical training program to reduce mental and physical stress of security guards, to develop the standard for the examination of physical strength suitable for the body figures of Korean people and the regular evaluation with the standard and to apply traditional folk-games such as the swing and the seesaw to the physical training for security guards.

The bodyguard is continuously training basic physical training and security art martial to protect the privacy of security target, prepare and deal with external contingencies and threats. Currently, university students majoring in security are required to take a judo class, one of their security art martial, which can use a technology to catch, crush and repress opponent. Therefore, this study identified the effects of systematic training on body composition, Performance fitness, growth hormones, and IGF-1 among male university students through a 10-week judo training program so that it was committed to providing objective data to enhance the value of judo as a security art martial and as a result, we have a conclusion as follows: After 10 weeks of judo training, muscle mass increased significantly, and body fat rate and BMI decreased significantly. The muscular strength and power of Performance fitness were shown to increase significantly, and growth hormones were shown to increase significantly. In total, the above results showed that for judo training university students, overall body composition improved positively, the muscular strength and power of active physical fitness improved, and growth hormones increased. Thus, the increase in muscle strength and growth hormones through judo training will encourage fat breakdown due to the development of the body's muscles and increase bone density in the spine, thereby reducing the risk of fractures and preventing injury to the trainees who are performing a security art martial. It will also greatly help your health by preventing obesity, cardiovascular and metabolic diseases, which eventually will enhance your bodyguard function and prolong your life as a bodyguard.

Intelligent monitoring, life entertainment, medical rehabilitation, and other fields are only a few examples where visual image technology is becoming increasingly sophisticated and playing a significant role. Recognizing Wushu, or martial arts, movements through the use of visual image technology helps promote and develop Wushu. In order to segment and extract the signals of Wushu movements, this study analyzes the denoising of the original data using the wavelet transform and provides a sliding window data segmentation technique. Wushu movement The Wushu movement recognition model is built based on the hidden Markov model (HMM). The HMM model is trained and taught with the help of the Baum-Welch algorithm, which is then enhanced using the frequency weighted training approach and the mean training method. To identify the dynamic Wushu movement, the Viterbi algorithm is used to determine the probability of the optimal state sequence for each Wushu movement model. In light of the foregoing, an HMM-based martial arts movements recognition model is developed. The recognition accuracy of the HMM model increases to 99.60% when the number of samples is 4,000, which is greater than the accuracy of the SVM (by 0.94%), the CNN (by 1.12%), and the BP (by 1.14%). From what has been discussed, it appears that the suggested system for detecting martial arts acts is trustworthy and effective, and that it may contribute to the growth of martial arts.

This research, to find the cultural identity of taekwondo, presents the historical origin of taekwondo in lights of Choi-centric theory, kwan-centric theory, karate inflow theory, and successive traditional martial arts theory. Then it investigates taekwondo's inner identity as a Korean traditional martial art according to presence, popularity, and independence, three factors of identity suggested by Tak, S. S.(2000).As a result, it reached these conclusions: First, taekwondo was formed after going through fusion of Hong Hi Choi, karate income in period of cultural severance during Japanese occupation, the first kwan leaders and Korean traditional martial arts, process of disorder and cultural reproduction. Second, taekwondo has essentially inherited and developed Korean barehanded martial arts' movements that lay stress on foot skills, and this distinguishes it from hand-skill-based Japan's karate and China's Wushu Furthermore, trunk/groin protectors and headgears are blended remarkably with taeguk patterns and traditional Colors of Five Directions. All terms rendered into pure Korean words shows the essence of Korean localization. It is therefore concluded that Koreans should, along with trying to overcome exclusive nationalism as a country of origin, build a new paradigm of establishing an identity as a global martial art sport.

The study of the theory and practice of Security Martial Arts should be concerned at first, for the development and progress for the future of Martial Arts. First, theoretical research that can be utilized in the real field should be performed, and such research outcomes are needed to be published as teaching materials and to be shared through various channels. Second, collaborative research of the characteristics of martial arts should be carried out. The Security Martial Arts would achieve a further development if training methods are complemented, and strengths and weaknesses of the events are fully understood. Third, studies for the independence of disciplines should be performed. The study field is derived into nine areas, and each is needed to be developed scientifically and systematically. Accompanied by sustainable study, academic autonomy of Security Martial Arts will be achieved.
