Maximizing Hakone Ekiden Performance With Low Pressure Chamber Training and Adaptive Data

Tokai University's Shonan campus features a "low pressure chamber."  With 20 cm-thick walls it is like a room on a submarine.  In preparation for the Hakone Ekiden, twice a week the school's athletes work out in the chamber on running machines and other equipment.  According to Tamotsu Terao, professor of exercise physiology at Tokai University's Sports Medical Science Laboratory, the interior of the 24 square meter, 3 meter-tall room can replicate altitude conditions ranging from 0 to 4000 m, and by adjusting temperature and humidity it is also simulate a variety of weather conditions.  "By setting it to 3000 m you create a situation that replicates running at Mt. Fuji's eighth stage," said Prof. Terao.  It is said that training in a low pressure, low oxygen environment increases the oxygen-carrying capacity of the blood, which improves the endurance and "last kick" capabilities essential in long-distance running.

During training, measurements were taken of each athlete's heart rate and arterial blood oxygen saturation, a representation of the binding rate of oxygen and hemoglobin in red blood cells, and along with their subjective assessment of whether different situations were "hard" or "easy" the study yielded valuable data.  "The aim is to bring out the body's inherent adaptability to the environment," explained Prof. Terao.  "Visualization of an athlete's condition via diagrams and numerical data will help us understand what are suitable goals and necessary training for that athlete."

Having been named to run Hakone's downhill Sixth Stage last year, 3rd-year Reo Kuniyuki commented, "It gave me the ability to push hard in the last part of the race.  If you combine it with outdoor training you can simulate the course's ups and downs."  The team dormitory also features a "low oxygen tent" that can create the same conditions found at 3000 m, improving their adaptation while they sleep and helping with recovery from fatigue.

Low pressure chamber training, also employed by Rio de Janeiro women's 200 m breaststroke gold medalist Rie Kaneto, was introduced in fully-fledged form at Tokai University in 2013 as part of its "Hakone Ekiden Support Project." Since then, the team's performances have steadily improved.  "I am very excited that we have added a very strong first-year class to that this year," said Prof. Terao.  "I want to help them execute their runs in perfect condition."  The good professor should be considered one of the team's star members.

Translator's note: Tokai University's current roster includes fourteen men with sub-14 bests for 5000 m, eight with sub-29 bests for 10000 m, and three with sub-63 bests for the half marathon.  More here.

Saku Chosei H.S. Makes It 2 In a Row - National High School Ekiden Boys' Race

While the girls' race was a blowout by 2022 champ Nagano Higashi H.S. , the boys' race at Sunday's National High School Ekiden was a tense battle of turnover that saw all of the final top four teams take a stab at leading. 2023 3rd-placer Yachiyo Shoin H.S. handled the first 2 of the 7 stages in the 42.195 km race, with lead runner Rui Suzuki delivering a bold run on the 10.0 km First Stage that produced the fastest-ever time by a Japanese runner on the stage, 28:43, and put Yachiyo Shoin 29 seconds out front. Last year's Fifth Stage CR breaker Tetsu Suzuki ran Yachiyo Shoin down to put 2023 champ Saku Chosei H.S. into 1st on the 8.1075 km Third Stage, but Genta Sugano of last year's 8th-placer Sendai Ikuei H.S. had other plans and took the lead on the 8.0875 km Fourth Stage. Smiling and fist pumping to the crowd almost the entire way, Taketo Tsukada of last year's 6th-placer Omuta H.S. moved up from 3rd to 1st by 2 seconds over Saku Chosei on the 3.0 k...

Japan Post Holds Off Sekisui Kagaku to Win Queens Ekiden National Title

  Japan Post  was back on top at the Queens Ekiden corporate women's national championships Sunday in Sendai, holding off last year's winner Sekisui Kagaku  over the second half of a race that came as close as 1 second to take 1st with a final margin of victory of 27 seconds. Sekisui Kagaku was out fast with a win on the 7.0 km opening leg by Erika Tanoura  and a new CR for the 12:56 second leg by Yuma Yamamoto , 17 seconds better than her own CR from last year. Last year's 4th-placer Shiseido  briefly led on the 10.6 km third leg with an excellent 33:17 stage win from Rino Goshima , but behind her Japan Post's Ririka Hironaka  returned from her latest injury problems to pass Sekisui Kagaku's Sayaka Sato  and hand off 6 seconds ahead. New recruit Caroline Kariba  ran Shiseido down on the 3.6 km fourth leg and put Japan Post 22 seconds ahead of Sekisui Kagaku, but a duel of marathoners between JP's  Ayuko Suzuki  and Sekisui's Hitomi Niiy...

Nagano Higashi Girls Lead Start to Finish to Win National High School Ekiden

2022 National High School Ekiden girls' champion Nagano Higashi H.S. was back in force after a 5th-place finish last year, leading start to finish to win this year's national title Sunday in Kyoto. Lead runner Airi Mashiba kicked it off with a 19:30 stage win on the 6.0 km opening leg, something that head coach Fumio Yokouchi said later that he hadn't been expecting. That ended up being Nagano Higashi's only individual stage win in the 5-leg, 21.0975 km race, but the rest of its team ran well enough to hold a lead that was never less than 11 seconds but never more than 21. Last year's 4th-placer Kunei Joshi Gakuin H.S. spent most of the race in 2nd, but over the second half of the race Sendai Ikuei H.S. , 2nd last year by just 1 second, came from further back to run Kunei down on the anchor stage thanks in big part to a critical stage win on the 4th leg by Tsubomi Tezuka that put anchor Aoi Hosokawa in position to catch Kunei's Mizuki Oda .
