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.

Ngetich and Mutiso Take Down Tokyo Legacy Half CR

In its 5th edition the Tokyo Legacy Half Marathon scored 2 new course records via Kenyans from the Ikaika agency, with 10 km WR holder Agnes Ngetich blasting 3 minutes off the old record to win by over 4 in 1:04:23, and Alexander Mutiso skimming just 1 second under the CR for the win by 5 seconds in 59:51. The 2 races played out completely differently, even if the paydays were the same for the winners. Surrounded by an envelope of male runners all the way to the final 100 m, Ngetich was out hard on the downhill in the first 5 km, hitting it on sub-64 pace in 15:08 before leveling out on the flat middle 10 km. Her next 2 splits projected to 1:04:09 and 1:04:17, and even with the uphill back to the stadium in the last 5 km she didn't fall far off from that, winning in 1:04:23. Runner-up Tabitha Njeri Kamau was nearly a mile back in 1:08:28, with Kamau's Mitsui Sumitomo Kaijo teammate Kazuna Kanetomo dropping a 1:10:17 PB for 3rd. Now an independent, track Olympian Kaede Ha...

Waseda Leads Top 7 Teams Under Izumo Ekiden CR, Ivy League Best-Ever 3rd (updated)

3rd last year, Waseda University scored its first Izumo Ekiden win since 2010, taking almost 2 minutes off the CR and leading the top 7 teams under the old record of 2:07:51 for the complete 6-stage, 45.1 km course. Waseda was 16 seconds back in 7th after the First Stage, but its 2nd runner Ojiro Honda made that up easily and put them 6 seconds out front. A massive 22:56 CR for the 8.5 km Third Stage by Shadrack Kipkemei (Nihon Univ.) dropped Waseda back to 2nd even though its runner Ryuki Suzuki broke the old CR too, but back-to-back CR on the next 2 stages by 1st-year Haruki Niizuma and Shunpei Yamaguchi put anchor Shinsaku Kudo out of reach of the rest of the field. Kudo duly won the 10.2 km anchor stage in 29:00, bypassing a 2:06 time entirely for a new 2:05:56 CR, just under 2:48/km average pace for the complete course. Defending champ Koku Gakuin University struggled a bit in the first half of the race but came on strong in the longer second half with 4th and 5th runners...

Route Inn Hotels Win National Corporate Women's Ekiden Qualifier for First Time

After Saturday's Hakone Ekiden Yosenkai qualifying race in Tokyo, 2nd-tier corporate women's teams were in Fukuoka for their own national championships qualifying race, the Princess Ekiden . With Queens Ekiden 19-placer Otsuka Seiyaku a DNS, 30 teams lined up for the 6-stage, 42.195 km race where the top 16 would go on to join the top 8 from last year's Queens Ekiden at next month's national race. Coming right in the middle of the international fall marathon season several teams had people still tired from Berlin and Chicago, with Daihatsu fielding Rika Kaseda and Natsuki Omori from Berlin, Tokyo Metro sending out its own Berlin duo of Mao Uesugi and Ayumi Morita , and Kraftia not playing its top member Yuka Akasaki after her solid run in Chicago last week. After a fast start from eventual 9th-placer Denso 's Rio Matsutani , Daihatsu took over on the Second Stage and held it until the Fifth, where a tired Omori dropped to 3rd.
