A new study by researchers from Nagoya University revealed that preoperative sarcopenia and exercise intolerance are associated with higher risks of medium-to-long-term mortality in patients with non-small-cell lung cancer.
Researchers at the University of Cincinnati say a regulatory protein found in skeletal muscle fiber may play an important role in the body's fight or flight response when encountering stressful situations.
A recent study suggests that preserving physical and mental health helps older adults experiencing cognitive impairment stave off declines in cognitive engagement.

Researchers at Kanazawa University report in the Japan Journal of Nursing Science a study of muscle pump action in the context of chronic lower-limb edema. They found that body posture and exercise habits affect the blood pumping action of muscles in the leg, whereas age generally does not.
Engaging in household chores may be beneficial for brain health in older adults. In a recent Baycrest study, older adults who spent more time on household chores showed greater brain size, which is a strong predictor of cognitive health.

Wearable electronic devices and biosensors are great tools for health monitoring, but it has been difficult to find convenient power sources for them. Now, a group of scientists from Japan has successfully developed and tested a wearable biofuel cell array that generates electric power from the lactate in the wearer's sweat, opening doors to electronic health monitoring powered by nothing but bodily fluids.
A study conducted by the University of Malaga evidences how children and adolescents' exposure to mobile phones and video games is associated with worse adherence to the Mediterranean diet, which healthy characteristics prevent obesity
A Kaiser Permanente study of nearly 50,000 people with COVID-19 suggested that regular physical activity provided strong protection from hospitalization, intensive care unit admission, and death. Even exercising inconsistently lowered the odds for severe COVID-19 outcomes when compared to people who were not active at all.
Physical exercise increases levels of cancer-fighting immune cells in animal models of breast cancer and slows the growth of tumors. In addition to lowering risk of developing cancer, structured exercise programs could help improve therapy for females with existing breast tumors. Exercise may also significantly improve treatment of breast cancer with immunotherapy drugs.
New research from McMaster University suggests the pandemic has created a paradox where mental health has become both a motivator for and a barrier to physical activity.
