A new study conducted in Japan showed that while you are at work, a brief period of exercise can provide your brain with positive energy. "The present study suggests that a simple exercise is preferable to a cognitively demanding exercise during working hours," said Dr. Keita Kamijo, Assistant Professor at the Faculty of Sport Sciences, Waseda University, Tokyo. .
For the study, Dr. Kamijo and his colleague Ryuji Abe had 28 men and asked them to perform tasks that challenged their work memory. This is the type of memory that allows you to keep and update information in your brain about things you are working on.
The subjects were asked to meet the challenges in three different situations: one before, one immediately after and another 30 minutes after three different test periods on three different days. The tests lasted 25 minutes each. For the first, individuals exercised on a stationary bike. In the next one, they performed a cognitive task while sitting on the bike, but without exercising. And in the third, they performed the task and exercised at the same time.
Previous studies have shown that aerobic exercise has a positive effect on people's ability to plan, pay attention, remember and perform multiple tasks at once. And in this spirit, the team expected to see better results in terms of accuracy and reaction time on the challenge where the guys were practicing on the bike.
As a result, it was found that the positive effects of participation in exercise alone were evident 30 minutes after cycling. But the intervention on exercise cognition involved "cognitive fatigue," the researchers said in the newspaper. Medicine and science in sport and exercise.
"It is possible that a greater amount of load on the brain is needed for chronic improvements in cognitive function, as with the overload principle of strength training," added Kamijo in the # 39; study.
