The Frog King of Japan - Kosuke Kitajima (Fast Secret)

The 25-year-old Kosuke Kitajima began to learn to swim at the age of 5, broke the world record four times in the five years from 2003 to June 2008, and experienced a long period of slump after winning two gold medals at the Athens Olympics, but through the efforts of Coach Hirai, the "Team Kitajima" research team and Kitajima himself, after entering 2008, Kitajima finally got out of various troubles, breaking the 100 meters Japanese national record (59 minutes 44 seconds) and the 200 meters world record (2 minutes 7 seconds 51) before the 2008 Olympic Games. The men's 100m and 200m breaststroke gold medals were included in the Japan 2008 Olympic team's gold medal winning program. According to relevant information, Kitajima was able to break the 200-meter world record again after a downturn of 2 years, which has an important relationship with his new swimming skills.

First, the widening and paddling range technology

According to kitajima's physical condition and weak strength, Japanese researchers have developed a unique new technology suitable for Kitajima - widening and paddling range, which was 60 cm in 2003 and 90 cm in 2008, 0.5 times wider.

In order to improve Kitajima's breaststroke paddling technique, Hirai instructors specially asked technical analysts to develop a shoulder muscle strength training plan for Kitajima to promote the increase of the width and strength of underwater paddling in both arms. Kitajima's strong water-catching and paddling techniques are now key to improving his performance.

Second, reduce the number of strokes technology

The Japanese have long found that they are better at highly technical breaststrokes, and the Olympic results since 1972 show that the physical conditions of the Japanese are not as good as those of Europeans and Americans who are tall and tall, breaststroke is a highly technical and "interesting" posture, and the skills of breaststroke are high.

According to relevant information, the pursuit of technological innovation by the "Team North Island" researchers has not been interrupted even in March 2008 when they went to the Arizona Plateau in the United States for training, and it can be seen from the analysis that the frequency of the North Island in 2008 was reduced by 6 times compared with 2003. Iwamotohiko in "Team Kitajima" believes that Kitajima used to stretch and glide for too long, and now the technology is that the hand and leg technical movements have not stopped, and the number of strokes has been reduced, and the propulsion has increased by 0.5 times.

Third, improve the paddling technology in 7 years

Kitajima's current breaststroke technique has been tested seven years ago. In 2001, Coach Hirai began to look for scientific research partners to solve the weaknesses in response to the lack of paddling power in kitajima, and entrusted Tamura, who was responsible for muscle transformation, to formulate a three-year muscle transformation plan in preparation for the 2004 Athens Olympic Games.

From 2003 to 2004, Kitajima's breaststroke was mainly strong in lower limb strength, his land bounce force was very strong, the vertical jump level was rare among swimmers, and the jumping level was almost the same as that of volleyball and track and field athletes, so Coach Hirai chose to maintain Kitajima's pedaling advantage, and the paddling action could not affect the pedaling effect of the breaststroke technique, which created Kitajima, which broke the 200-meter world record in 2003 and won 2 Olympic gold medals in 2004.

Fourth, the use of 4-wheel thruster technology

After the 2004 Athens Olympic Games, Kitajima's body was fully cultivated and adjusted, and the upper limb strength training was increased again, and the strength training of the wrist, arm and latissimus dorsi muscle group must be strengthened to improve the effect of paddling. Kitajima said: "At first, it felt a little uncoordinated, but since 2007 I have slowly experienced improvement, and since the beginning of 2008, I have felt that there is almost no coordination, and now I really feel the profound meaning and charm of breaststroke."
