Hi an alle,
ich weiß nicht ob bei euch das Thema schon längst bekannt ist, aber mir war es neu.
Im folgenden
NY Times Artikel wird über Studien berichtet ("The dozen or so studies, from peer-reviewed journals, are summarized in three articles in September's Journal of Sexual Medicine. "), die einen Zusammenhang zwischen Fahrrad Fahren und Impotenz festgestellt haben. Dabei spielt die Form des Sattels eine wichtige Rolle. Ich weiß, dass die NY Times den Abruf von älteren Artikeln kostenpflichtig macht, deswegen heir ein paar Einzelheiten für die jenige die diesen Beitrag später lesen:
- "... those who ride bikes rarely or for short periods need not worry. But riders who spend many hours on a bike each week should be concerned, he [Dr. Steven Schrader] said."
- "Researchers have estimated that 5 percent of men who ride bikes intensively have developed severe to moderate erectile dysfunction as a result. But some experts believe that the numbers may be much higher because many men are too embarrassed to talk about it or fail to associate cycling with their problems in the bedroom."
- "Women cyclists have not been studied as much, he [Dr. Irwin Goldstein] added, but they probably suffer the same injuries."
- "The area in question is the perineum, between the external genitals and the anus. "When you sit on a chair you never put weight on the perineum," Dr. Schrader said. "But when you sit on a bike, you increase pressure on the perineum" sevenfold."
- "The research shows that when riders sit on a classic saddle with a teardrop shape and a long nose, a quarter of their body weight rests on the nose, putting pressure on the perineum. The amount of oxygen reaching the penis typically falls 70 percent to 80 percent in three minutes."
- "Today's ergonomic saddles have splits in the back or holes in the center to relieve pressure on the perineum. But this may make matters worse: the ergonomic saddles have smaller surface areas, so the rider's weight presses harder on less saddle, Dr. Schrader said. The perineum may not escape injury because its arteries run laterally and they are not directly over the cutouts. The arteries can come under more pressure when they come into contact with the cutouts' edges. Thick gels on saddles can also increase pressure to the perineum, the studies found, because the material can migrate and form clumps in all the wrong places."
- "The safest seats and saddles, experts say, force the rider to sit back firmly on the sit bones so the perineum is protected. Dr. Schrader advocates saddles that do not have noses. "
