Leg exercise is critical to brain and nervous system health

New research shows that using the legs, particularly in weight-bearing exercise, sends signals to the brain that are vital for the production of healthy neural cells. The groundbreaking study fundamentally alters brain and nervous system medicine — giving doctors new clues as to why patients with motor neuron disease, multiple sclerosis, spinal muscular atrophy and other neurological diseases often rapidly decline when their movement becomes limited.

Higher aerobic fitness levels are associated with better word production skills in healthy older adults

Researchers found that older adults’ aerobic fitness levels are directly related to the incidence of age-related language failures such as ‘tip-of-the-tongue’ states.

Rehabilitating lactate: From poison to cure

When George Brooks first began investigating lactate, or lactic acid, sports physiologists saw it as a muscle poison that lowered performance. His research over decades has reversed that picture, showing that it is the body’s way of revving up for exercise or to fight disease. Clinicians are now planning clinical trials to use lactate to treat traumatic brain injury and a host of illnesses, including heart attacks, inflammation and swelling.

Exercise could make the heart younger: Mice make over four times as many new heart muscle cells when they exercise

After a heart attack, patients must create new heart muscle cells to heal. A new study shows that mice make more new heart muscle cells when they exercise compared to when they do not. This was true for both healthy mice and those that had experienced a heart attack. Findings demonstrate that one reason exercise is beneficial to health is that it increases the heart’s capacity to regenerate.
