The researchers found that 12 weeks of vigorous exercise produced stronger bones, improved insulin sensitivity (reduced diabetes risk) and less of the most-deadly belly (visceral) fat. The team observed that blood levels of the hormone osteocalcin, made by bone-producing osteoblasts, were raised by vigorous exercise, and thereby may explain the response among bone, fat, and pancreatic cells.
