Both time-restricted eating (TRE) and high-intensity interval training (HIIT) have been shown to improve cardiometabolic health in people who are overweight and at risk of serious disease. Now a randomized, controlled trial has tested whether combining these two approaches is more effective than either of them on their own. The results, publishing in the journal Cell Metabolism on October 4, show that the combination improved the average long-term glycemic control compared to a no-intervention control group and induced 2-fold greater reductions in fat mass and visceral fat area compared with each intervention in isolation.

“Isolated TRE and HIIT have received increasing attention for being effective and feasible strategies for at-risk populations,” says senior author Trine Moholdt,...

Scientists have shed new light on the effects that high-intensity interval training (HIIT) has on human skeletal muscle, according to a study in men published today in eLife.

The findings suggest that HIIT boosts the amount of proteins in skeletal muscle that are essential for energy metabolism and muscle contraction, and chemically alters key metabolic proteins. These results may explain the beneficial effects of HIIT on metabolism and pave the way for additional studies exploring how exercise impacts these processes.

“Exercising has many beneficial effects that can help prevent and treat metabolic diseases, and this is likely the result of changes in energy use by skeletal muscles...

Researchers at the University of Tsukuba found that, despite only covering about one-third of the distance in HIIT compared with that covered in endurance training, similar improvements in exercise capacity and brain function were observed for both forms of exercise.

“We investigated how rats’ muscles and brains — specifically, the region of the brain involved in spatial learning called the hippocampus — adapted to these types of exercise, and how the rats consequently learned and remembered navigating mazes,” explains Professor Hideaki Soya, the principal investigator.

In the experiment, rats were assigned to 1 of 3 groups — resting, endurance running, or alternating intervals (short sprints and rest) — during training sessions on treadmills 5 days/w...

Exercise may play a role in reducing the growth of colon cancer cells according to new research published in The Journal of Physiology. The study found that after a short session of high intensity interval training (HIIT), growth of colon cancer cells was reduced, and this also increased indicators of inflammation.

For a long time, the focus on exercise has been on the positive changes in the body that occur following a longer period of training. However, these findings suggest that the effects following a single session of HIIT, an exercise regime involving short, high energy bursts are also important...
