“Dr. van Loon explains that cooling a trained muscle reduces local blood flow and slows the processes that support recovery and remodeling. In a controlled human study, postexercise cooling lowered muscle protein synthesis during recovery from resistance exercise.”

“In the Dallas Bed Rest and Training Study, three weeks of strict bed rest at age 20 reduced the five participants' exercise capacity more than 30 years of aging, showing how strongly deconditioning can affect cardiorespiratory fitness.”

“Evidence suggests that exercise exerts antitumor effects by increasing the body's insulin sensitivity, reducing sex-steroid hormone levels, and dampening the immune response (and the accompanying inflammation).”

“Could choices you make before having kids affect their DNA? Animal study suggests exercise causes changes in sperm DNA and results in offspring that have stronger neuronal connections in the hippocampus, and better learning and memory than those born to sedentary fathers.”

“> They found that production of neural stem cells improved by approximately 200% compared to the middle-aged mice that did not exercise. In addition, the survival of new nerve cells increased by 170% and growth by 190% compared to the sedentary middle-aged mice.”

“In more than 25,000 adults who reported no leisure-time exercise, several one-to-two-minute bouts per day were associated with lower all-cause, cardiovascular, and cancer mortality. Short activity breaks can also interrupt prolonged sitting.”

“After 10 minutes of light exercise (30% VO2max) high-resolution functional magnetic resonance imaging showed better connectivity between the hippocampal dentate gyrus and cortical areas linked to detailed memory processing. The magnitude of the enhanced functional connectivity also predicted the extent of memory improvement suggesting that even light exercise is good for the brain.”

“FTA: > By injecting MSCs into mouse leg muscles prior to several bouts of eccentric exercise (similar to the lengthening contractions performed during resistance training in humans that result in mild muscle damage), researchers were able to increase the rate of repair and enhance the growth and strength of those muscles in the exercising mice.”

“Subjects rested (control), walked briskly for 30 min (walking) or performed 5×30 s maximal sprints (high-intensity). Another study found that the beneficial effects of high-intensity interval training on postprandial triglyceride levels were abolished 2 days after exercise.”

“A recent study involving older rats found that regular aerobic exercise reduces age-related inflammation in the brain and improves the balance between nerve fibers and their protective myelin coating. Researchers had older rats exercise on a treadmill for eight weeks.”
