Endurance exercise accelerates the development of heart problems in individuals with a particular genetic mutation, a new study finds. In mice with a mutated version of desmoplakin, a protein that maintains the heart wall, exercise made the heart walls come apart sooner. The findings offer insight into how to best manage exercise in individuals with the mutation.

As we age or develop neurodegenerative diseases such as Alzheimer's, our brain cells may not produce sufficient energy to remain fully functional. Researchers discovered that an enzyme called SIRT3 that is located in mitochondria — the cell's powerhouse — may protect mice brains against the kinds of stresses believed to contribute to energy loss. Furthermore, mice that ran on a wheel increased their levels of this protective enzyme.

In a new animal study, University of Missouri researchers examined how the development of obesity and insulin resistance contribute to bone-fracture risk and whether exercise prevents weight gain and diabetes and protects bone health. They found obesity and Type 2 diabetes negatively affected bone, but exercise prevented weight gain and diabetes and increased bone strength. These findings could inform interventions to improve bone health among individuals with obesity and Type 2 diabetes.

Regular physical activity could play a role in helping women at high-risk of breast cancer delay the need for drastic preventive measures such as prophylactic mastectomy, according to new research led by the Perelman School of Medicine at the University of Pennsylvania. Results of the WISER Sister study help clarify the emerging connection between exercise and breast cancer risk. As a result of the new findings, the authors suggest that women who have an elevated breast cancer risk or worry about having such risk should consider doing 30 to 60 minutes of aerobic activity per day for five days per week.
