Scientists still do not know why the timing of exercise produces different effects. To gain a better understanding, an international team of scientists recently
Exercise causes the body to release hundreds of signalling molecules that improve our health in different ways. Now, an international research team including researchers from Karolinska Institutet have mapped how these signals are released by different organs in mice following exercise at different times of the day. Their atlas of exercise metabolism, published in the journal Cell Metabolism, may in the long term contribute to more effective exercise therapies that are timed to the body clock.
Almost all cells regulate their biological processes over a 24-hour period, otherwise called a cell's circadian rhythm. To do so, cells use a biological clock that cycles different genes on and off throughout the day and night. Scientists already know that our metabolic health can suffer when our biological clock breaks down, due to shift work or sleep disorders, for example. However, it's unclear how exactly the biological clock of people with type 2 diabetes differs from healthy people.
