It also has the beneficial side effect of lowering blood sugar levels, according to the report.In previous experiments, the researchers had seen that mice breathing low-oxygen air had dramatically lower blood glucose levels than normal. That meant the animals were quickly using up glucose after they ate, putting them at lower risk for diabetes. "The idea that muscle remodeling requires the output of these brain neurons is a pretty big surprise," study leader Erik Bloss of The Jackson Laboratory in Bar Harbor, Maine said in a statement. "If you give a normal mouse access to a running wheel, they will run kilometers at a time," said Bloss. "When researchers stimulated SF1 neurons for an hour after treadmill sessions, mice showed enhanced endurance gains and reached higher maximum speeds.
