“Participants completed one hour of cycling at 65 percent of their maximum aerobic capacity on one day and rested the next day. The researchers collected biopsies from the participants' thigh muscle after they had rested and 15 minutes after they exercised.”

“Notably, a small group of endurance athletes who developed an overtraining syndrome involving muscle damage and persistent fatigue showed shorter muscle telomeres, highlighting the importance of sufficient recovery.”

“Those repeated interruptions may keep muscles more responsive to insulin throughout the day, and potentially even into the next, in a way that one short moderate-intensity exercise session cannot reproduce.”

“Daily fluctuations in testosterone have not been shown to drive muscle protein synthesis. However, supraphysiological steroid doses are anabolic. Many testosterone boosting agents are on the market, but Dr. Phillips states they are ineffective, and it's better to focus on resistance exercise.”

“One of the mechanisms behind the beneficial effects of exercise is its ability to induce autophagy in skeletal muscle and, potentially, other organs. In this clip, Dr. Guido Kroemer describes the anti-diabetes and anti-obesity effects of exercise-induced autophagy.”

“During shivering, skeletal muscles undergo repeated, rapid contractions that produce little net movement and instead produce heat. Nonshivering thermogenesis generates heat without shivering by unique mechanisms in skeletal muscle and adipose (fat) tissue depots.”

“When intake drops, the body quickly turns to its major amino acid reservoir—skeletal muscle. Flirting with inadequate intake means you immediately start breaking down muscle tissue, which is especially costly with aging where losses carry functional consequences.”

“The brain shifts did not follow the rhythm of breathing or heartbeats in awake mice. The abdominal muscles became active just before the mice started moving. The brain shifted shortly after the abdominal muscles switched on, and the two signals remained closely linked during movement.”
