Gold Study

Proven Athletic Performance

In short- If you can drill it for 10 minutes you can drill it for 14 minutes. Many athletes see a small bump in power/wattage, less cramping, recovery but the study details the ability to ride at longer when you are burying it.

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 time at 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 Kˆlner 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.

INTRODUCTION

Intense and prolonged physical exercise cause lactic acidosis via accumulation of intramuscular hydrogen ions (1). Skeletal muscles „go acid“, a condition which creates fatigue and decreased exercise performance (2). Thus, a lot of sport nutrition supplements focus on buffering lactic acidosis but scientific evidence ist still scarce. In this study we ypothesized that supplementation with a Nano Absorption Formulation® (NAF, Extreme Endurance, Euronutrition BV, Netherlands) attenuates lactate concentration after exhaustive exercise.

 METHODS

19 male athletes joined this placebo-controlled, double-blind, cross-over study and conducted incremental cycle ergometer step tests until individual exhaustion. The 1st ergometer test (day 0) was conducted to determine performance (P) data (VO2, lactate, Pmax). Then, subjects were randomly assigned to placebo or NAF tablets. After 10 days of NAF or placebo  treatment the 2nd test was performed (day 10), followed by a 10 days wash-out. On day 20 the groups exchanged the treatments from the first 10 days. Finally, on day 30, the 3rd test was conducted. The provided dosage was 2 x 4 tablets for the 1st 2 days (load dosage) and then daily dosage was calibrated to subject´s body weight. The NAF tablets provided a.o. minerals, antioxidants and protease enzyme papain. To determine lactate, capillary blood from earlobe was collected before exercise, at every step of the incremental test, at the end of exercise (Pmax lactate) and 5 min post exercise (recovery lactate).

Supplementation with athletic performance formula decreases lactate concentrations in trained athletes after exhausting incremental cycle ergometer test.

 RESULTS

We analyzed a significant difference in Pmax lactate concentrations between treatments (p < 0.05). With NAF, Pmax lactate was attenuated by a trend compared to placebo (p = 0.062). There were no differences between treatments concerning recovery lactate (p > 0.05). 

CONCLUSIONS

The NAF treatment decreased lactate concentrations at exhaustion (Pmax) compared to placebo indicating a substantial buffer capacity of the applied nutraceutical at high intense exercise.
