Tsukuba [Japan]May 17 (ANI): Recent research by researchers at the University of Tsukuba has shown that durability High strength Intermittent training Improves athletic performance and brain function Rat..
A study published in the cerebral cortex similar motor performance and brain function, even though it covered only about one-third of the distance in HIIT compared to the distance covered by endurance training. It was found that improvement was observed with both forms of exercise.
“How did we investigate Rat‘Muscles and the brain-especially the area of the brain involved in spatial learning called the hippocampus-adapts to these types of exercise and how Rat As a result, I learned and learned to navigate the maze, “explains Senior Researcher Professor Hideaki Soya.
In the experiment Rat Assigned to one of three groups-alternate intervals of 5 days and 4 weeks (short sprints and breaks) during breaks, long distance runs, or training sessions on the treadmill.
Both long-distance running and HIIT resulted in weight loss, increased muscle mass, and longer athletic performance compared to control. However, the increase in the aerobic capacity of the cells is due to the soleus muscles (mainly muscles that have slow muscle fibers and are functionally suitable for endurance) and the plantaris muscles (mainly fast muscles to meet high energy function requirements). It was found in muscles with fibers). In the endurance running group and the HIIT group, respectively.
Rats in both groups showed better memory of spatial learning attempts in searching for escape platforms in the water maze. In the hippocampus, increased cell development (neurogenesis) was also observed in both motor forms. However, the level of signaling protein (BDNF) that promotes neurogenesis was increased by HIIT, but not by long-distance running, but its receptor (TrkB) level was increased by both. ..
Why did long-distance running not increase BDNF expression when BDNF expression is known to be affected by exercise? The answer may be in the mediating role of stress on BDNF expression. Exercise is a kind of stress. Although the stress indicators of both exercise groups were found to be similar, this series of studies may lead to future studies.
“This study showed that low-momentum HIIT exercise regimens improve spatial memory, and that these improvements are supported by changes in hippocampal neuroplasticity. Previous studies have shown continuous light. -Intensity training had similar beneficial effects, but continued High strength I didn’t train. “
“Therefore, it seems that the benefits of exercising may actually depend on optimization, the trade-off between exercise time and intensity,” he added.
The future may be imminent where exercise therapy can be adjusted to improve both physical and cognitive characteristics. (ANI)
