Aikido is a modern Japanese martial art developed by Morihei Ueshiba in combination with his martial arts research, philosophy and religious belief. Zhizhi's goal is to create an art that practitioners can use to defend themselves while protecting attackers from harm. Aikido is often translated as "a way of uniting with life energy" or "a way of harmonizing spirit".

Aikido was created by Morihei Ueshiba, which some Aikido practitioners call "Aikido"? Sensei (great teacher). The word Aikido was coined in the twentieth century. Zhizhi's idea of Aikido is not only the synthesis of his martial arts training, but also the expression of his personal philosophy of universal peace and reconciliation. In his life, until now, aikido has evolved from Aikido studied by Zhizhi to various expressions of martial artists all over the world.

Zhi Zhi mainly developed Aikido from the late 1920s to the 1930s by integrating the older martial arts he studied. The core martial arts derived from Aikido is the great RYI Aikido jujitsu. Shangzhi studies with the martial arts Reviver Takeda Xikong. In addition, it is said that Zhizhi studied Tenjin shin'y-ry with tozawa tokusaburi in Tokyo in 1901, gotiha yagyi shingan RYI under Nakai masakatsu of Sakai from 1903 to 1908, and judo with Takagi of Tanabe in 1911.

Daiti RYI's art is the main technical influence of Aikido. In addition to airhand throwing and joint locking techniques, Shangchai also combines training exercises and weapons, such as those used for spears, short sticks and bayonets. However, most of the technical structure of Aikido comes from fencing.

Did Zhi Zhi move to Hokkaido? He began his studies in 1912 and in 1915 at sokaku, Takeda. He and day ry? It lasted until 1937. However, in the second half of that period, Zhizhi began to keep a distance from the Takeda and the dati. At that time, Zhizhi called his martial arts "Heqi Budi". It is not clear when Zhizhi began to use the name "Aikido", but it officially became the official name of art in 1942, when Dai Nippon butoku Kai participated in the reorganization and centralization of Japanese martial arts sponsored by the government.

Like almost all Japanese martial arts, in Aikido, training involves both physical and psychological aspects. There are many kinds of physical exercises in Aikido, including general physical adaptation and regulation, as well as specific techniques. Because a large part of any Aikido course is throwing, beginners can learn how to fall or roll safely. The specific techniques of attack include attack and snatch; the defensive techniques include throwing and pin. After learning the basic skills, students will learn the freestyle defense against multiple opponents and the skills with weapons.

Sports goals pursued with Aikido include: control of relaxation, proper movement of hip and shoulder joints, flexibility and endurance, with less emphasis on strength training. In Aikido, pushing or stretching is more common than pulling or contracting. This difference can be applied to the general fitness goals of Aikido practitioners.

In Aikido, specific muscles or muscle groups are not isolated and cannot improve tone, quality, or strength. Aikido related training emphasizes the use of coordinated whole body movement and balance, similar to yoga or Pilates. For example, many Daoists perform warm-up exercises at the beginning of each class, which may include stretching and ukemi.

The most common criticism of Aikido is its lack of realism in training. Attacks by uke (which must be defended by Tori) have been criticized as "weak", "sloppy" and "less ironic than the attack.". Weak attacks from uke will cause Tori to respond conditionally and result in insufficient skill development for safe and effective practice of both sides. In order to solve this problem, some styles will reduce students' compliance with the passage of time, but according to the core concept, this is after proving their ability to protect themselves and training partners. Xiaodouguan Aikido solves this problem through competition. This approach to adaptation has been debated among patterns, some of which argue that there is no need to adjust its approach because these criticisms are unjustifiable, or that they are not trained for self-defence or combat effectiveness, but for mental, health or other reasons.

Another criticism is about the shift of training focus of Ueshiba from 1942 to the end of his seclusion in Yanyu County in the mid-1950s, as he increasingly emphasized the spiritual and philosophical aspects of Aikido. As a result, when the receptacle strikes the key point, the receptacle enters (irimi) and begins to use the receptacle technology. The difference between the skin (front) and the Ural (back) technology and the use of weapons are not emphasized or eliminated from practice. Some Aikido practitioners believe that lack of training in these areas will lead to a decline in overall effectiveness.

On the contrary, some Aikido patterns are criticized for not paying enough attention to the spiritual practice emphasized by Zhi Zhi. According to shiora Minoru Shibata of Aikido magazine, "O-Sensei's Aikido is not a continuation of the old, but a very different concept from the past of martial arts and philosophy." That is to say, aikido practitioners who focus on Aikido originated from traditional jujitsu or swordsmanship are different from those of Shangzhi. These critics urged practitioners to accept the idea that "Shangzhi's Transcendence of spirit and universal reality is the basis of the paradigm he shows."
