Proven Athletic Performance

For the past decade I have owned and operated Corpus Diagnostik in Hilpoltstein, Germany. Corpus Diagnostik offers the competitive athlete a multi-faceted facility for training. We chose Hilpoltstein for our location because it neighbors Roth, Germany, the host of the largest Ironman Race in Europe.

My career began as a strength and conditioning coach for a professional soccer club in Germany and at the same time I trained and competed as a triathlete. As a triathlete, I came to realize that there were not many targeted training or testing resources for elite competitors. I meant to change this by starting Corpus Diagnostik.

Each winter for the past ten years, Corpus conducts 3 to 4, 2-week, high intensity triathlon training camps in Lanzarote, Spain. These training camps are conducted at Club La Santa, a world-class athletic training center. Each 2-week camp focuses on one of the three triathlon sport disciplines. Each camp is hosted by a top, pro triathlete who excels in either swimming, biking or running. These camps are usually booked months in advance because elite athletes want to get an early start on the season and thoroughly enjoy leaving the winter cold of Europe and train in the warmth of the Canary Islands.

Over the years, Corpus Diagnostik has conducted over 6000, VO2 Max tests on elite athletes. Triathletes and elite pro athletes from all over Europe find our multi-faceted training as a critical part of their competitive program.

We approach all aspects of an athlete’s regimen and because of this, numerous sport nutrition companies have approached us over the years to conduct tests and clinical studies using our elite athletes using their products. We have tested sport drinks, sport bars and sport supplements and most have shown little or no benefit in our athletes’ performances.

Last year, Dr. Volker Tzscheetzsch and I were contacted by the largest nutraceutical company in Germany to do a large, double-blind, placebo controlled, cross-over study on a new product formula that had been developed by a Dutch sports nutrition company. After reviewing the test protocol, we agreed to begin interviewing applicants for a new study. We selected 22 elite athletes for this clinical.

The test was to be a 30-day study. After all participants received a baseline test, each athlete was given a clinical protocol with dosage instructions and were given a 10-day dosage of either Product A or Product B. At the end of ten days, the same battery of tests were given to the eleven athletes who used product A and the eleven athletes who used product B. After this first 10-day test was completed, all 22 athletes were taken off product usage for a 10-day washout period. On the 21st day, all 22 athletes took another baseline test and Group A switched to Product B and Group B switched to Product A. The same dosage protocol was used for the next 10 days, then final testing was done on all 22 elite athletes.

Both Dr. Tzscheetzsch and I knew something unique and special was happening with the performance of almost half of our 22 athletes after the first 10-day tests were completed. We had tested some of these athletes dozens of times prior to this clinical as part of their normal triathlon training and they were putting numbers on their charts that we had never seen before. Needless to say, we were very anxious for the final test results to be compiled. What we found in those final numbers was very impressive. The average lactic acid reduction was 15% and the athletes increased their aerobic threshold by an average of 41%.

I was so impressed by the increased performance in these athletes that I asked this Dutch company if I could do my own study using the active product on 5 of my pro-triathletes for a longer 30-day study.

What I found in my own study was the longer the use of the active product, the longer I saw continued improvement with an increase in VO2 Max and power output. My athletes also felt the difference and wanted to stay on this new product formula called Extreme Endurance.

One more question remained; Was it drug-free and would it be safe for all of my pro athletes? Extreme Endurance was sent to the largest sports lab in the world, HFL, in the UK. We also requested it be sent to Germany for the Kölner Liste certification. It passed both labs and their stringent testing and is now certified ISO/17025 drug-free.

Since the clinical study, we have done additional blood testing of our athletes before, during and after VO2 Max tests. Using a Dunkelfeld microscope, we could see healthy looking, free-flowing, red blood cells at the beginning of our test. At the end of the VO2 Max test, some of our athletes’ blood showed irregular shaped blood cells with many cells stacked together like a stack of coins. These damaged blood cells are unable to transport oxygen and helps explain why recovery takes longer after a Max VO2 test, a hard training session and certainly a triathlon event.

As we continued to evaluate athletes’ blood work, we began to see a pattern where blood work of those elite athletes using Extreme Endurance had little or no damaged blood cells after VO2 Max testing. This shows that the Hydrogen ion (H+) buffers found in Extreme Endurance help buffer the exercised induced acid and this in turn helps protect normal red blood cell function. From this blood work we see why athletes using Extreme Endurance say they recover faster.

The ingredients in Extreme Endurance are fairly basic; Potassium and Magnesium are acid buffers. Added Trace Minerals, Antioxidants and Protease Enzyme Papain stimulates anti-inflammatory agents that help with muscle pain and soreness.

All of my elite athletes now take Extreme Endurance as part of their overall training. Heidi Jesberger, one of my pro athletes that I have trained and tested 72 times in the past 6 years, has improved her VO2 Max test from 57 ml/kg to 63 ml/kg, which is over a 10% increase. We have also been able to increase her training volume by over 15%. When you look at all of Heidi’s test scores over the past 6 years you see she was most fit in 2004 and 2005 when her VO2 Max tests were 57 ml/kg. To have an elite pro athlete improve their VO2 Max scores by 10% is remarkable. Heidi has continued to test at 63 ml/kg for over a year using Extreme Endurance.

Needless to say she doesn’t want to stop using Extreme Endurance. Timo Bracht has also seen his training volumes increase and his test scores keep getting better and better. I expect Timo to have his best Ironman season this year. All of our Extreme Endurance athletes have set new PRs and are able to do this with less muscle soreness and quicker recovery.

After a decade of testing numerous sports products, I would encourage any athlete seeking to increase wattage, power and performance to give Extreme Endurance a try.

First Queen of the Challenge Walchsee-Kaiserwink

Yvonne van Vlerken (Tri Team Lustenau/Endurance Team Austria) crowns herself to the first queen of the Challenge Walchsee-Kaiserwinkl.

Thomas J. Vonach (Tri Team Lustenau/Endurance Team Austria) with silver in the amateurs.

Chilly 12 degrees air- and cold 15 degrees water- temperature were no hurdle for about 1200 starters to test themselve at the premiere of the newest Challenge-race on a very scenic but demanding course.

As a clear favorite in the women´s race Austrian resident Yvonne van Vlerken knew the course by numerous training stays in Sankt Johann (her friend and manager Thomas is half Tyrolean) where she had also prepared for her 2008 long-distance world record (at the Challenge-”mother-race“ in the Frankish Roth). Eva Dollinger, winner of the Ironman Austria in ’10, was also as valid title-expectant like the multiple Ironman winner Edith Niederfriniger/ITA.

Yvonne van Vlerken came out of the water 4 minutes off the then leader Tyrolean Dollinger and this should be also the only discipline in which she was beaten on this day. On bike the Dutchwoman showed her class and that her curve shows upwards and into the direction of Ironman Hawaii. With the quickest bicycle time in 2:24:38 she equaled her swim-gaps on Eva Dollinger who could show a strong performance on the bike.

The half marathon on the selective because quite undulating track in four laps around the Walchsee turned into an enjoyable one for the 31-year-old Dutchwoman where the Ironman Austria-winner Dollinger had nothing to oppose. Already after two laps van Vlerken had ligh-footed opened up 3 minutes, then she switched, as from Head-coach Frank Senders recommended, in the autopilot and could enjoy the idyllic scenery with the „Wilden Kaiser“- mountains sitting proudly above the Walchsee

At the finish-line nearly 5 minutes separated Yvonne van Vlerken and Eva Dollinger.

Thomas J. Vonach who had to fight a bacterial infection of the digestive system and the remains after his amateur long distance-world champion’s title at the beginning of August. With low expectations he went to the race, however, he even surprised himself and with a solid portion ability to suffer he reeled in the silver medal in his strongly occupied AG. Overall he was ranked 27th and became 3rd Austrian in the field. The race impressed with a perfect organisation and will be for many triathletes probably soon a fixed date in the annual racecalendar.

Quote Yvonne: „I have been pleased very much by this race and it was the last test before leaving for US to prepare for Ironman Hawaii. It was great to win here, for me it was also a sort of home-race and I am impressed by the perfect organisation of the premiere-event.“
