Circadian rhythms: influence when you should exercise
TRAINING in sync with your inner body clock could result in better performances. At least, that’s the suggestion of scientists at Northwestern University’s Feinberg School of Medicine after they discovered that circadian rhythms in our muscle tissue control the muscle’s metabolic response and energy efficiency according to the time of day.
Each of the body’s cells, including those in muscle, contain an inner clock that regulates how they adapt to the environment and activity across 24 hours. In his study on laboratory mice published in the latest issue of the journal Cell Metabolism, Joseph Bass, professor of endocrinology and lead author, reported that muscle cells seem more efficient during an organism’s normal waking hours.
