“Danger” skipping box how to prevent September 9 18:51
“20,000 cases per year”. This is the number of accidents that occurred in the “Tobi Box” in the physical education class at school. In elementary and junior high schools, it is said that the most common cause of serious injuries such as broken bones, and there are cases where disabilities remain. I searched for how to prevent it. (Reporters from the network report department)
The reality that has been visible in the data
A symposium held in Yokohama on the 24th of last month. The theme was “Protecting children from repeated skip box accidents”. The actual situation of the accident that should be noted here was introduced.
The National Institute of Advanced Industrial Science and Technology analyzed the data provided by the Japan Sports Promotion Center during the three years up to FY2016. According to the survey, an average of more than 210,000 accidents occurred annually during physical education classes at elementary, junior and senior high schools (including technical colleges) nationwide.
By exercise, the number of “basketball” was the highest at 51,000, followed by “Tobi Box” at 2,600, and “Soccer Futsal” at 19,000.
Looking further ...
Here, if we classify it only for exercises with serious injuries such as broken bones with a total medical cost of more than 75,000 yen, “jumping boxes” accounted for the most in elementary and junior high schools.
Elementary and junior high school students most frequently injured wrists and fingers, and more than 40% of injuries were broken.
How are you injured?
This is a video that captured the moment when the wrist was aimed at a flying box introduced at the symposium. In this way, when you put your hand on the jump box, you will not be able to jump well, and there will be a lot of cases where you will get hurt when your hand gets on your hand.
As for the after effects
In addition, in the 10 years up to FY2016, we found that there were 27 accidents that left obstacles such as fractures that made joints difficult to bend.
In addition to what was reported at the symposium, there are cases where students who lost their balance when jumping dropped from their heads onto the mat, damaged the spine, and became inconvenient from the chest down.
Why are there so many accidents? Prof. Masanosuke Matsu of the Toho University, Faculty of Sports and Health Policy, who is familiar with the Tobiko Movement, said that “Tobikita is a“ move with both hands and throws the body forward ”, which is not easy to do in daily life. If you jump in an unfamiliar state, you will feel afraid and apply the brakes, which often results in accidents by putting weight on your hands or losing balance. "
How to teach
So how are the safety measures for the skip box? In May, the Japan Junior High School Athletic Federation and lawyers familiar with sports accidents surveyed junior high school physical education teachers nationwide answered 718 schools nationwide.
For safety reasons, 88% of respondents answered “Yes” and 12% answered “None” when asked if they had a supporting role for the students who were playing boxes.
As for whether or not a special preparatory exercise is being carried out in front of the box, 73% are “going” and 27% are “not doing”. All responded that many schools are taking measures.
However, if you look at the questionnaire in more detail, even if you answered "There is an assistant", the correspondence is divided according to the school, "all students are eligible", "some students only" and "according to the technique" I found out.
As for the specific content of the special preparatory movement, the most common responses were “stretch” and “flexible”.
Kenta Okamoto, who conducted the questionnaire, said, “I know that safety measures have been taken to a certain extent, but based on the fact that there are many accidents, it is necessary to consider further preventive measures.” .
First of all, “No skip box”
“Training the necessary movements and sensations without using a box”. Prof. Matsumoto mentioned earlier points out that pre-exercise is one of the points to prevent accidents.
It is indispensable to fully acclimatize the body to the movement unique to the box that "holds both hands and throws the body forward".
Recommendation of skipping horse
As one of them, we recommend “Jumping Horse” which jumps like a flying box with a hand on the back of a crouched person.
In addition to being able to adjust to the right height between children, it is said that you can learn how to use the body safely because it does not run up.
Before starting the box, everyone performs a “leap jump” and it is necessary for children who are not used to using the body to not be able to jump the box forcibly.
Dogs are good too
Also recommended as a more basic movement that can be done in the lower grades of elementary school is “dog running”.
By putting your hand on the ground and proceeding like four legs, you can get used to the use of the hand and the posture when the waist is higher than the position of the head and jumping through the box.
Do not evaluate height
Prof. Matsumoto says that children are unreasonable and easily injured when evaluated in terms of how high the number of steps can be taken. He points out that schools should focus on evaluation in terms of “stability” and “how to learn”.
Voices of pros and cons of the net
Opinions on the pros and cons of doing classes in the first place are raised on the Internet about the number of accidents in the box.
While there are voices saying, “If it is dangerous, you should just abolish the box itself” or “I don't know what the box is useful for,” while “Do everything because it ’s dangerous, what do you do?” “Contain the potential of the child from the beginning Some people say that it is not good.
The significance of Tobibox
In the questionnaire to junior high school physical education teachers, 86% of the schools that answered “significant” for the class in Tobiko Box were significantly higher than 14% of “I don't feel significance”. There is a sense of achievement. "
On this point, Professor Matsumoto said, “How to expand the possibilities of my physical abilities” is one of the roles of physical education.
However, the current situation with too many accidents is a problem, and I think it will be necessary to make a thorough preparation in advance and complete safety measures on the part of the school, including teachers' awareness. "
How can we reduce children's athletic ability while reducing “danger”? I felt that a careful response was needed according to the physical strength and skill level of the children.
History of Tobi Box
According to Professor Yoshiaki Matsumoto of Osaka Gakuin University, who is familiar with sports history and gymnastics, the origin of Tobibox is in Sweden, Scandinavia, and its history dates back to the early 19th century. Around that time, “Swedish gymnastics” was devised in order to nurture healthy people, and jump boxes were incorporated.
Incidentally, Michiaki Nagai, who appears in the “Daten” TV drama currently on air, tried to popularize the gymnastic equipment “Rokuboku”, but this was also taken from Swedish gymnastics.
Later, in 1913, the “Guideline for School Gymnastics Teaching”, the current course of study, was established, and Swedish gymnastics was introduced to school physical education as a rational exercise. To be installed at school.
In response to this trend, it is said that elementary and junior high school learning guidelines provide for “instrumental exercise” including skipping boxes in current physical education classes.
