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.

For the second time in the last three weeks, a Japan-based Kenyan ran the fastest time in the world this year for 10000 m at Yokohama's Nittai University Time Trials series. On October 20th it was 2015 World U18 Championships 3000 m gold medalist Richard Kimunyan (Hitachi Butsuryu), 20, with a 27:14.70  that surpassed Ugandan Joshua Cheptegei's world-leading mark by almost five seconds. This time it was 2018 World U20 Championships 5000 m silver medalist Stanley Waithaka (Yakult), 18, taking almost two minutes off his PB to break Kimunyan's mark with a 27:13.01 win.

Both winners received support from 2014 Commonwealth Games steeplechase gold medalist Jonathan Ndiku (Hitachi Butsuryu), who ran season bests for 2nd place each time, 27:50.38 three weeks ago and 27:28.27 on Saturday. 2013 World U18 Championships 3000 m bronze medalist Alexander Mutiso (ND Software) was also under 28 minutes, running just off his PB at 27:42.16 for 3rd.

Go Ahead and Call It a Comeback - Niiya Breaks Shibui's Course Record in Return to Road Racing

Ladies and gentlemen, Hitomi Niiya is back.

You might remember Hitomi Niiya from the 2013 Moscow World Championships 10000 m, where she led the entire way only to get destroyed over the last lap and finish 5th in 30:56.70. That made her the third-fastest Japanese woman ever over that distance, but not long after that race she quit the sport entirely, getting an office job as far away from athletics as she could and not running for almost five years.

But the pull of the 2020 Tokyo Olympics is strong, and, now 30, early this year she made the decision to try to make a comeback. Under the eye of former men's 800 m national record holder Masato Yokota she ran a 3000 m and two 5000 m time trials on the track between April and October before choosing the East Japan Women's Ekiden for her return to the roads and the longer distances.

The East Japan Women's Ekiden celebrated its 34th running Sunday, 9 stages totaling 42.195 km through the Fukushima countryside with teams from eac…
