Exercise may generate new blood vessels by Delia Cruceru

A new study presented at the European Society of Cardiology meeting revealed that exercises help in creating new blood vessels. The initiators of this study, a team from the Leipzig University in Germany, gathered a small group of 37 persons to study them. Dr. Robert Hollriegel from the team discovered that people with serious heart failure who rode a bike for up to 30 minutes a day for four months produced new stem cells in their bones. Also in their muscles appeared new blood vessels. The study revealed that people who didn't exercise had no change in their vessels or muscles. According to the study if you exercise regularly, the physical activity will determine the heart to send 10 times the normal amount of blood to the muscles being used, then the stem cells are dispatched to relieve this stress and may repair any damaged parts, helping you to adapt to the stress and building new blood vessels and strengthening muscles. "People think that if they have heart failure, then they're at the end of the road and they can't exercise," said Dr. Freek Verheugt, a cardiologist at the University of Nymegen in the Netherlands. "But this study shows that exercise can work to produce new blood vessels, even in patients with serious heart disease." Doctors should now prescript to exercise the same way they prescript to patients drugs, said Dr. Francois Carre of Rennes University Hospital in France.
