The hot days continue, and you need to be careful about heat stroke.



There is also data that about 70% of heat strokes that occur in junior high schools and high schools nationwide occur in the activities of the athletic club, and experts say that the judgment of club activity leaders and the efforts of students can prevent heat stroke. I call it important.

According to the information compiled by the Japan Sport Council, the number of heat strokes in junior high schools and high schools nationwide has been 45,143 in the past 10 years, of which 29,816, which is about 70%, is the sports club. It is happening in the activity in.



Thirteen of them have died.

Professor Hideto Tanaka of the Faculty of Education, Yokohama National University, who is familiar with measures against heat stroke in physical education and club activities, said that in order to prevent heat stroke in club activities, the instructor correctly grasps the risks and makes appropriate judgments for the students. I point out that it is important to work.

First, comprehensively decide whether to carry out club activities on a hot day

The first thing Professor Tanaka points out is to decide whether or not the instructor will start club activities on a day when it is expected to get hot.



First, grasp the environmental conditions of the place where club activities are performed based on the "heat index" and "heat stroke warning alert", and then consider the characteristics of each competition, such as "it is easy for heat to accumulate because you wear armor", and then club activities. It is said that it should be judged comprehensively whether or not to do it.

Creating an atmosphere where students can take a break at their own discretion

On top of that, when deciding to carry out club activities, it is important to "create an atmosphere where you can take breaks at your own pace at any time."



The initial symptoms of heat stroke, such as "a little uncomfortable," "fluttering," and "lack of concentration," are often known only to the students themselves, and whenever they feel a change, taking a break at their own discretion does not worsen the symptoms. Because it is important to.



For that reason, it is said that what I want the leaders of club activities to keep in mind is a voice that holds down two points.



▽ The first is to convey that "heat stroke may occur" at meetings before starting club activities.



By focusing on heat stroke, it becomes easier for students to notice even slight changes in their physical condition.



▽ The second is to convey that "resting is not cheating."



Physical fitness varies from person to person, and it also depends on the physical condition of the day.



It is important for the instructor to create an atmosphere that does not consider resting as "skipping" or "slurping".



Students are forced to continue practicing because of their sense of responsibility and anxiety about being out of regularity.



"I want you to try not to create an atmosphere where you have to practice."

Be careful of practice including running

And the next thing to watch out for is running.



According to Professor Tanaka, running is often included in the practice when heat stroke occurs due to the activities of the athletic club.



First of all, running in the heat is an act that increases the risk of heat stroke by itself.



With that in mind, I would like you to keep two points in mind when conducting a running practice menu.



The first point is that the running practice menu is "Beginning of practice, what to do when you are physically fit".



Running in a tired state increases the risk of heat stroke.



For example, he points out that it is dangerous to run until you get tired at the end of practice.



And the second is "do it with shorts that allow heat to escape easily".



In order to release the heat generated from the body by running, it is effective to wear shorts to increase the exposed area of ​​the skin.



Even in sports such as baseball where you usually wear long pants uniforms, you can reduce the risk of heat stroke by changing to shorts if you are not worried about injury.

Professor Tanaka of Yokohama National University "Learn the latest knowledge"

Professor Tanaka says, "When it comes to heat stroke, it can be dangerous to teach with the feelings and values ​​that you had when you were a player. I want you to learn the latest knowledge and data and use it for countermeasures." ..



The risk of heat stroke that cannot be avoided when performing club activities in hot weather.



As the heat of the day exceeds 35 degrees Celsius, we need to be more careful than ever to avoid the risk of life-threatening students.
