Evenings are more productive for working out: Study

According to the report,  evening work out can be more productive. The details were published in the Journal of Cell Metabolism. Research teams looked at the association between time of day and exercise performance primarily in mice.

Because mice are nocturnal, one thing they had to do was translate mouse timing to human timing, by distinguishing between the active phase and resting phase of the mice rather than using numbers on the clock. Asher's group started by putting mice in treadmills at different times of day within their active phase. They examined the exercise capacity of mice upon different exercise intensities and regimens and found that overall exercise performance is substantially better in the "mouse evening" compared to the morning hours.

According to the researchers found that in response to exercise in the "mouse evening," there were higher levels of a metabolite called ZMP (5-aminoimidazole-4-carboxamide ribonucleotide). ZMP is known to activate metabolic pathways that are related to glycolysis and fatty acid oxidation.

Therefore, it is likely to contribute to the increased exercise capacity in the evening. The researchers also studied 12 humans and found similar effects. Overall, the people in the study had lower oxygen consumption while exercising in the evening compared with the morning; this translated to better exercise efficiency.

Recseachers also  found that a protein called hypoxia-inducible plays an important role and that it is activated by exercise in different ways depending on the time of day.
