متن کاملCircadian Rhythm, Exercise, and Heart.
Circadian rhythm is an evolutionarily conserved mechanism from archaea to human. To deal with the day-night changes in the environment on earth, circadian rhythm modulates the biological function to coordinate an appropriate timing for each process. Circadian rhythm and exercise have important impacts on each other. Exercise is a strong entrainment signal for mammalian circadian clock. 1 Proper...
