At the Olympics, both athletes and spectators are “heat stroke risk” What do you do? September 29, 17:59
However, looking at the heat index, which is an index for preventing heat stroke, during the 17 days of the Tokyo Olympics in summer, it shows the danger that it is necessary to stop the exercise in principle for most of the Olympic period. I understood that it was. The Organizing Committee held an action meeting that gathered outsiders to discover new ideas to prevent heat stroke. What is the forefront of heat countermeasures and their effects?
"Danger" is 14 days "Severe vigilance" is 17 days of 3 days
The Ministry of the Environment publishes a “heat index” on the website, which is calculated based on data such as temperature, humidity, and heat from the ground, and serves as an index for preventing heat stroke.
According to this, the Tokyo heat index from July 24th to August 9th, which is the period of the Tokyo Olympics, is 14 days out of 17 days. It turned out that it was more than 31 degrees indicating "danger".
The remaining three days were over 28 degrees, indicating a “strict vigilance” that it was necessary to avoid strenuous exercise and going out in hot weather.
Also, from August 25 to September 6, which is the period of the Tokyo Paralympics, 1 out of 13 days was “Danger” and 8 was “Severe Warning”.
60% of Tokyo Olympic Games venues are outdoors
There are 42 venues for the Tokyo Olympics, and 27 of them, more than 60%, are outdoor venues with no roof.
Even in indoor venues, the audience may be lined up for a long time by checking baggage before entering the competition venue, and measures against heat are required.
On the other hand, at the Tokyo Paralympic Games, 9 venues, more than 40% of the 21 competition venues, are outdoor venues.
Midsummer for American football and European football
In the first place, why is this Tokyo Olympics held during the hottest summer season?
It can be said that when the IOC = International Olympic Committee solicits candidacy for the host city of the 2020 Games, it requested that the event be held between July 15th and August 31st.
According to the officials, after September, there is a concern that the audience and TV viewers will decrease due to the American professional sports season such as American football NFL and basketball NBA, and European professional soccer season. about it.
On the other hand, Tokyo's invitation committee at that time had a plan submitted to the IOC with a period of 17 days from July 24th to August 9th. It ’s an ideal climate that allows athletes to perform at their best, because they ’re often warm and temperate. ”
Qatar's Doha, on the other hand, submitted a plan to hold mid October to avoid midsummer, but was rejected in the document review.
Forefront of measures against heat of athletes
As for the severe heat expected in the Tokyo Olympics and Paralympics, measures are being taken against athletes, such as changing the start time of the competition from the plan at the invitation stage.
Onshore marathon is 7:30 am to 6am, racewalking is 50km for boys from 7:30 am to 5:30 am, 20km for men and women is 9am to 6am, and triathlon is 10am to 7am personal. At half past seven rugby was changed from 10:30 am to 9:00 am respectively.
Of these, the marathon started at 7:00 am and was 30 minutes ahead of schedule, but it was one hour earlier due to the heat of summer last year.
In addition, in the MGC = Marathon Grand Championship of the marathon on the 15th of this month, which became a test tournament, the Japan Athletics Federation cooperated with the Organizing Committee to increase the water station every 2.5 km instead of every 5 km. After 29 km, we took measures to increase five places. In addition, in some water stations, players put ice bags that can be expected to reduce body temperature by placing them on their hands or sides, and there are some players who actually get ice. It was.
The IOC = International Olympic Committee has also started to deal with heat for athletes. In August, the IOC has written a heat countermeasure guide for athletes entitled “BEAT THE HEAT” for the Tokyo Olympics. Published on the official website.
The handbook contains recommendations for training in a hot environment similar to Tokyo at least two weeks ago to acclimate your body to the heat, and the importance of cooling your body before the competition. The
The Organizing Committee will also consider coordinating with competition organizations to handle the situation with further changes in time when the heat becomes more severe.
3 times with a large cold air fan ↓ Artificial snow in the auditorium
The Organizing Committee has planned 56 test tournaments to confirm operational issues for the Tokyo Olympics and Paralympics, and has finished 24 tournaments by 29th.
Since it is close to the actual climate, it is positioned as a “priority period” for measures against heat from July to this month, and various measures have been verified, especially for beach volleyball, boats, triathlons, hockey, and marathons performed outdoors. I did it.
The organizing committee and the Tokyo Metropolitan Government have taken at least 30 measures for spectators. Among them, the beach volleyball tournament held in July will be used for baggage inspection waiting for admission. We installed a tent and a large cold air blower.
At 1 pm on July 25, when NHK interviewed, the “heat index” used as an index to prevent heat stroke was 33 degrees outside the tent, whereas the wind of a cold air blower It was confirmed that the inside of the awning tent where the sun goes down is 29 degrees and 6 minutes, 3 degrees lower.
In addition, at the Umi no Mori Water Stadium, where the roof of some of the spectators' seats has disappeared due to the reduction of maintenance costs, this month's canoe test tournament used artificial snow on the spectators using snowfall machines. An attempt was made to let it fall. While the voice of a staff member who was regarded as a spectator was heard, it was cool, but the snow was not reaching the place expected by the wind, and the "heat index" did not change, and the floor was wet and slippery. Some issues were also found.
In addition, at the hockey test tournament held last month, information on the heat index was announced at the venue to call attention to heat stroke. "Ponder" was placed and a fan was distributed.
Organizing Committee, to verify the effect of the measures that have been tried so far, we decided to put together the future of the heat measures of policy in prospect the end of next month.
Parasol Frozen plastic bottle Shade confirmation app
The trial period to test the measures against the severe heat that will be the subject of next year's Tokyo Olympic and Paralympic Games has ended in 29 days.
The Organizing Committee has recently held a countermeasure meeting that gathered outsiders to find new ideas to prevent heat stroke, and is rushing to prepare for the start of less than 10 months .

In addition, there is a plan to bring frozen plastic bottles, a plan to make it possible to check the shaded place in the app using thermography that looks at different colors of temperature, and a fashionable and cool place that you want to post on SNS There were also plans to disseminate information.
The Organizing Committee is considering the possibility of bringing in plastic bottles and parasols under certain conditions while considering safety.
Hidemasa Nakamura, GDO = Games Delivery Officer, who organizes the tournament at the Organizing Committee, said, “The heat countermeasures are very extensive and it is impossible to do just one measure. I want to move forward. I think we can always get over by sharing wisdom. "
Experts “Keep moisture, know the shade to cool down and cool places”
Yasushi Miyake, Director of the Advanced Critical Care Center, Teikyo University Medical Hospital, who is familiar with heat stroke, said, “It is determined that the tournament will be held during this period, so it is absolutely necessary to do it safely.
