Iron Injections Remain an Issue in Japanese High School Girls' Distance Running

To treat anemia some of the country's top high school ekiden teams inappropriately utilize iron injections that could have a harmful effect on athletes' health.

Iron injections are primarily used to treat serious anemia arising from iron deficiency, but according to experts they also improve endurance. As a result their use has spread across the country over the last 20 years, primarily among female athletes who are more prone to anemia.

Following a 2015 case in which an athlete was confirmed to have suffered liver damage as a result of excess iron levels, in April, 2016 the JAAF issued a warning for coaches to stop the practice of injections, saying, "The accumulation of iron in the internal organs has deleterious effects on the body." In an interview two women who graduated prior to the JAAF's warning talked about their firsthand experience in high school. Under their coaches' direction both used iron injections throughout their high school careers and produced strong results, but after graduating they never improved and came to regret their past histories of injection.

"Coach would say, 'OK, time to go do it,' and then they'd inject me," one woman who graduated from a high school in East Japan and continued to compete in university said of her high school days. Her coach would take her to a local hospital up to three times a month, and a week before a big race all five members of the ekiden team would receive injections. The coach would tell them, "It has vitamins mixed in so it's fine."

A doctor who worked on the athlete confirmed, "All five girls received iron injections and iron medicine drips." The doctor said that the coach brought girls from the team to the hospital every week beginning around September, and that they would often receive injections without having any blood testing done beforehand.

At the National High School Ekiden both the athlete and her team finished high up in the field. If she had kept developing at that rate she could have become one of the country's top runners. When she had blood work done for her university team she was the only one whose results indicated a massive overload of iron. The concentration per ml of serum ferritin, a protein which serves as an indicator of the body's iron storage level, far exceeded the normal range of 25 to 250 nanograms. Her university coach was surprised, saying, "You've been putting something in your body, haven't you?"

Ever since high school the woman hasn't felt right. She developed problems with reduced functioning of her internal organs, thought to be an effect of iron overdose, and there were times when even just jogging was hard. "In high school I was ignorant," she said. "Your times might improve by taking injections, but I'd never want to go back to those days again."

Some top high schools have continued the practice of iron injections for team members even after the JAAF's 2016 warning. Although the schools publicly state that they have abandoned the technique, some staff members have admitted it in private interviews, and the JAAF believes that other schools may likewise be continuing to employ the injections.

A JAAF spokesperson commented, "The environment surrounding our athletes is in a crisis situation. We want to work hard to fully understand the extent of the use of iron injections and will take appropriate measures promptly." The JAAF will issue another warning at the Dec. 23 National High School Ekiden Championships and is considering mandatory submission of blood test results at next year's edition.

"...is considering mandatory submissions of blood test results..."
Wow! Has this ever happened before at high school level in any country in any sport?
In fact this article prompted me to re-read your 19 April 2016 linked article and ponder your footnote with a little more gravity. Hmmm...
Once again, thanks for all the translation.

What the hell is wrong with Japanese parents? Like the athletes, they think the coaches are gods. Hello - they're just high school coaches! Don't be so irresponsible!

Overdose of iron does not improve normal human performance. It only ends anemia.
These girls were anemic. The performance seemed to be improved because you became normal.
That is why iron is not doping.
The crisis is not iron injection. They should ban is hard exercises and hard diet. If they will use the doping test approach, it will increases anemia.
I hope children read the news and children will not overdose iron for performance improvement. It does not improve performance. It is not good for your life.

I am curious to know what you put the liver damage down to? Over training? Drinking alcohol?

I do agree that diet and training needs to be balanced for young athletes - particularly young female athletes - in order for them to be healthy and perform at their best.

But giving an athlete three iron injections a month which results in said athlete's iron levels being abnormally high is just wrong and dangerous.

Chepkirui Wins Nagoya Women's Marathon

Heavy-duty favorite Sheila Chepkirui took the win at Sunday's Nagoya Women's Marathon , pulling away after 30 km to cruise in for 1st in 2:20:40. Erratic pacing early saw the first and second groups only seconds apart for much of the first half of the race, the top group slower than planned and the 2nd group a bit ahead of schedule. At halfway in 1:10:37 the front group included Chepkirui, #2-ranked Ruti Aga and last year's runner-up Eunice Chumba , and Japanese contingent Sayaka Sato , Rika Kaseda , Natsuki Omori and Mao Uesugi . Omori was the first to drop, then Uesugi, then Aga, who ultimately dropped out before 30 km. When the pacers stopped at 30 km Chepkirui made a move that dropped Kaseda and strung out Chumba and Sato behind her, but all four came back together once before another surge put Kaseda away for good. As Chepkirui inched away Sato and Chumba passed each other repeatedly, and Chumba could only watch as the top Japanese runner got away from her again thi...

Nagoya Women's Marathon Preview

The Nagoya Women's Marathon , the world's largest women-only marathon and the last race in the selection cycle for September's Tokyo World Championships, happens Sunday. Weather conditions are looking better than what they had in Tokyo and Osaka the last two weekends, 7Ëš at the start and rising to 12Ëš with sunny skies. The wind looks a bit stronger than ideal, but it could be worse. Fuji TV has the live broadcast starting at 9:00 a.m. Sunday local time, and if you've got a VPN you should be able to watch the TVer streaming . One option for  a leaderboard is here , and another here . We'll have some coverage on @JRNLive . Just like last time around there are three Ethiopian and Kenyan-born athletes at the top list, this time it being sub-2:20 women Sheila Chepkirui , winner in NYC last year, and Ruti Aga , winner in Xiamen in January, and last year's Nagoya runner-up Eunice Chebichii Chumba . But last year Yuka Ando still pulled off the win, so there's a c...

Who's Running Tokyo Worlds?

The Japanese marathon teams will be the most prestigious ones to be on for September's Tokyo World Championships, and with Sunday's Nagoya Women's Marathon the window for Japanese athletes to get onto the JAAF's shortlist closed. Who's on it? The final decision won't be made until Mar. 26, but let's look through the selection criteria and see who's guaranteed, who's pretty likely, and who has a chance. 1. Marathon medalists at the Paris Olympics - There weren't any, so nobody makes the team this way. Akira Akasaki (Kyudenko) and Yuka Suzuki (Daiichi Seimei) were the top placers, both of them running PBs in the Olympics to finish 6th. You'd think that would count for something a year later, but you'd think wrong. 2. JMC Series IV Champions - The top point scorers in the Japan Marathon Championship Series IV, which ran from April, 2023 to March, 2025, earn places on the marathon teams along with cash prizes. For women that's Yuka ...
