“Exercise elicits a wide range of physiological changes in the body that improve multiple aspects of cardiovascular, neurological, and metabolic health. The molecular mechanisms that drive these improvements are not well understood.”

“Regular exercise has long been known to protect cognitive functions such as attention, memory, and processing speed as we age. A recent study found that exercise may also improve older adults' language comprehension by enhancing cardiorespiratory fitness—the body's capacity to deliver and use oxygen-rich blood.”

“An 8-week exercise intervention that included cycling and walking increased blood flow to brain regions involved in motor control and reward processes and improved dopamine-related brain function in overweight and obese individuals.”

“Approximately 95% of patients had improved mood after exercise. There have been several other intervention studies showing that exercise improves mood in people with depression, improves psychosis in people with schizophrenia, and improves anxiety.”

“Although pharmaceutical treatments for depression are available, many people with depression do not respond to the medications. A new study demonstrates that aerobic exercise benefits people with depression, especially those whose symptoms are more severe.”

“The purpose of this randomized controlled pilot study was to determine the safety and feasibility of chronic exercise combined with resveratrol supplementation. The investigators split a group of 60 adults (average age, 71 years) with physical limitations into three groups.”

“People who regularly engage in high-intensity aerobic exercise have nearly half as many upper respiratory infections as sedentary people, a 2010 study found. Those who engage in high-intensity aerobic exercise also experience fewer and less severe upper respiratory symptoms than those who engage in lower-intensity exercise.”

“From the article: > Muscle tissue can remodel itself, which is one reason why exercise becomes easier when we do it regularly, Lessard says. Over time, aerobic exercise such as running or swimming can alter muscle fibers to become more efficient at using oxygen during exercise.”

“Exercise choice changes the cost of that effort. Dr. Norton recommends leaving more repetitions in reserve on demanding compound lifts, where failure can sharply reduce later performance, while pushing lower-risk isolation exercises closer to failure.”

“Although this was a small study, it supports a growing body of evidence suggesting exercise is a potent strategy for staving off cognitive decline in aging. One contributor to cognitive decline is the loss of blood-brain barrier integrity.”
