Dietary intake likely plays a role as well, said Shawn Arent, professor and chair of the Department of Exercise Science at the University of South Carolina. He was not affiliated with the study. “You’ve had more waking hours during the day, you are more awake, you have had the chance to power the system a little more,” Arent said.

Higher body temperatures in the afternoon can also improve muscle performance, almost like a built-in daily warm-up.

“When you start to realize how powerful this body clock can be, then if you do things like take food at the wrong time of day, or be inactive at the wrong time of day, or be inactive at times. where you need to be active, this can have a major impact, “Schrauwen added.” The good news is that you can also use it to your advantage. “

Schrauwen said that not snacking in the afternoon and avoiding late-night meals can have a big impact on a person’s weight and overall health. Other studies have shown that late eaters tend to consume more total calories than those who eat earlier in the day.

Arent also said it’s important to eat protein after a workout, but the exact timing of this nutrient intake after exercise can be flexible – so don’t feel the need to take a shake immediately after a workout. race.
