“VO2max is a measurement of your body's ability to consume oxygen. It is particularly relevant during aerobic exercise because it means that your body can take in more oxygen and deliver it to your muscles, enabling you to run/walk/bike/swim faster for a given effort.”

“CTSB, a lysosomal enzyme, is secreted from muscle into circulation after exercise and is associated with memory function and adult hippocampal neurogenesis. Older adults with cognitive impairment have lower serum and brain CTSB levels.”

“What happens during a heart attack? Heart attack—also known as a myocardial infarction—occurs when blood flow to a part of the heart is restricted, depriving the heart muscle of oxygen. A lack of blood flow leads to the production of reactive oxygen species.”

“All-out cycling forces working muscles to break down fuel and recycle energy rapidly, producing an immediate rise in metabolites. That intense demand can also stimulate muscles and other tissues to release signaling proteins.”

“BDNF receptors located on the pancreatic cells that produce insulin promote insulin release by these cells. Secretion of BDNF from skeletal muscle affects glucose tolerance in mice by stimulating insulin release from the pancreas.”

“Current World Health Organization guidance counts activity regardless of bout length and recommends 150 to 300 minutes of moderate activity or 75 to 150 minutes of vigorous activity each week, plus muscle-strengthening work.”

“It is hard to know what the mechanism for improved arterial tone is but may be due to functional influences on smooth muscle tone, perhaps linked to reductions in oxidative stress. This study's authors have some conflict of interest, but the pilot study is interesting nonetheless.”

“Mice continued their diet for a total of 12 to 13 weeks. After 10 weeks, the researchers measured changes in the animals' body weight, glucose sensitivity, serum cholesterol, fatty liver, muscle performance, and immune response when challenged with bacterial endotoxin.”

“This is the first time that resistance training has been shown to prevent brain atrophy in MS patients. Previously it was shown to help improve their muscle strength and ability to walk.”

“Diluting the blood of old mice enhanced muscle repair, increased neurogenesis in the hippocampus, and decreased fat stores and fibrosis in the liver – recapitulating the effects of heterochronic blood exchange.”
