Exercising at this time of day can do a double duty

Exercise has many health benefits for the body, but the effect of exercise varies from time to time. According to HindustanTimes, scientists still do not know why the effect of exercise varies with the timing of exercise.

Different signals with the time change

A recent study published in the journal Cell Metabolism showed that the body produces different organ-specific signals after exercise depending on the time of day, and these signals affect sleep, memory, and overall health. "All cells regulate their biological processes over a 24-hour period, and previous research has confirmed that synchronizing exercise with the body's circadian clock can enhance the health benefits of exercise" , says Juliette Zierath, professor at the Novo Nordisk Foundation Center. at the University of Copenhagen. The international team of scientists conducted a series of experiments on mice that exercised early in the morning or late at night, and samples of blood and various tissues, including brain, heart, muscle, liver and fat were removed and analyzed. Scientists have discovered hundreds of different metabolites and hormone signaling molecules, and monitored their evolution by exercising at different times of the day.

Regulation of the biological clock

Through the study, a better understanding can be gained of how tissues communicate with each other, and how exercise helps re-regulate circadian rhythms, and faulty biological clocks have been linked to an increased risk of obesity and type 2 diabetes. Furthermore, the study identified new exercise-induced signaling molecules and requires further research; To understand how it affects health. "Not only are we showing how different tissues respond to exercise at different times of the day, but we are suggesting how these responses are related to the ordered adaptation that controls systemic energy balance," says Jonas Trebak, associate professor at the 'study.

Study Restrictions

Experiments have been conducted on mice, and although mice share many genetic, physiological and behavioral characteristics with humans, they have important differences, mice are nocturnal creatures, and exercise is limited to running on a treadmill, and the effect of gender, age and medical history was not taken into account. “Despite its limitations, this study is important and helps to direct future research that helps us better understand how and when exercise affects health,” says Shogo Sato, assistant professor in the Department of Biology and one of the participants in the study.
