There are only 9 weeks left until Kona. The IRONMAN world championship on the Big Island, Hawaii is for many an athlete the highlight of his or her career that one should enjoy. I am not talking about pro athletes, for them it is an obligation and in many ways not a question of joy. But for the many age groupers racing there should be joy. Be it as it may, it is hard work to get to Hawaii and it is hard work to finish there. Many currently linger along this very thin red line between overreaching and overtraining, and try to solve the riddle how to achieve peaking on time.

Working with biestmilch and being a physician I am confronted with a lot of health issues of athletes and it is exactly now, that I receive these posts and comments talking about the discrepancy, the lacking proportionality between training efforts and performance. You may feel in top form, you worked hard for many weeks, and then when the day comes, you feel sluggish in the swim or toasted on the bike already. Maybe you overlooked the discrete signs that guide you along the path of productive and unproductive workouts. In this post I would like to start writing about the various symptoms that may give you a frame of reference and standpoint of where you are with your training, symptoms that may help you to assess your very personal body condition.

Sebastian Kienle told me before Challenge Roth: “Well, I don’t feel really perfectly prepared, but you know it, if you feel perfectly prepared, then it may as well be the case that you did too much.” You may know that Sebastian got 2nd in his 1st long-distance race and that he raced under 8 hours. To remember his sentence could help in situations of doubts.

To fall prey to overtraining can happen to everybody who loves his or her sport, because sport can actually become an addiction which has nothing to do with being overzealous or doped. The feeling of whole body fatigue as well as the feeling of being able to deliver peak performance are rewarding and seducing. Both extremes can lure us to do more to get more! One day “the more” turns into “too-much” and can bring about overtraining, a sneaky process that may overrun you! A complex phenomenon that needs elucidation still. (more…)

Since I am involved with biestmilch/colostrum, the diagnosis of lactose intolerance seems to have spread like an epidemic. Self-diagnosis and the diagnosis made by physicians – sorry to say so – as an easy way out for all kinds of functional gastrointestinal disorders has become so common that one has to develop reservations.
If you take your time and read the latest research done on this topic, doubts about the reliability of this diagnosis appear more than justified. Don’t get me wrong, there is no questioning about people suffering gastrointestinal symptoms, only the given reason may be highly questionable.

The topic is of great relevance for athletes who very often suffer from functional gastrointestinal disorders due to stress, be it mechanical, biochemical or mental. My impression is that these problems are rarely adequately analyzed and diagnosed, but overhastily labelled either as infectious, lactose- or stress-induced (means vegetative). The following paragraphs can only give you a very superficial idea of a complex problem.

Lactose and lactase, what is it about? A more state-of -the art view on intolerance

As far as it is known, lactose has no special nutritional value for adults. It is the most important source of energy during the first year of a human’s life, providing almost half the total energy requirement of infants. Lactose has several applications in food industry. It is used in sweets, confectionery and sausages because of its physiological properties: lactose provides a good texture and binds water and color. To be absorbed it needs to hydrolyzed. This is what lactase is doing. Lactase is found abundantly at the beginning of the small intestines. It is found at the tip of the intestinal villi and is therefore more vulnerable to intestinal diseases that cause cell damage (other enzymes that degrade other sugars are located deeper in the cell lining).  If lactase secretion drops about one tenth or less of suckling level after weaning, then this is referred to as primary hypolactasia. Congenital lactase deficiency is extremely rare. Secondary hypolactasia or maldigestion may be due to operations or damaged mucosal lining of the gut (infections, inflammatory diseases). This is where biestmilch comes in. The minimum amount of lactose that may cause symptoms is not known, and may be a very subjective thing. On average amounts of dozens of grams have to be ingested to cause symptoms (e.g. 50 grams are used in the lactose tolerance test for diagnostic reasons). Don’t forget that you ingest lactose with many kinds of foods!

Biestmilch is low in lactose. It only contains 5% to 7% of the amount of lactose in milk. (more…)
