New understanding of how exercise impacts the heart

For the first time researchers are beginning to understand exactly how various forms of exercise impact the heart. Massachusetts General Hospital (MGH) investigators, in collaboration with the Harvard University Health Services, have found that 90 days of vigorous athletic training produces significant changes in cardiac structure and function and that the type of change varies with the type of exercise performed.

Discovery of new way to prevent cardiac fibrosis

In a study that points to a new strategy for preventing or possibly reversing fibrosis - the scarring that can lead to organ and tissue damage - researchers at the University of California, San Diego School of Medicine have determined that a molecule called Epac (Exchange protein activated by cAMP1), plays a key role in integrating the body’s pro- and anti-fibrotic response.

Menstrual status and long-term cardiovascular effects of intense exercise in top elite athlete women’

It has long been assumed that menstrual disorders amongst elite female athletes are related to tough training regimes combined with insufficient energy intake. However, a new doctoral thesis from the Swedish medical university Karolinska Institutet overturns old ideas that elite sport can damage the health. Many elite female athletes can have a congenital condition, that gives them higher levels of testosterone and that might even contribute to their sporting successes.
