Effects Of Single Aerobic Exercise Of Different Intensities On Inhibitory Control And Food Decision-making In Obese Subjects Who Have Failed Restrictive Die

Obesity has become a serious public health problem in today’s society.Abnormal psychological factors such as inhibition control and food decision-making are important causes of obesity.Obese people who fail restrictive diets may suffer from eating disorders resulting in obesity due to their weak inhibition and control ability and abnormal food decision-making process.Exercise is an effective means to repair inhibition control and improve food decision making.A single session of aerobic exercise can significantly enhance inhibitory control and thus improve food decision-making.However,previous studies have shown that a single session of aerobic exercise with different intensity has different effects on inhibition control and food decision-making.The purpose of this study was to reveal the effects of a single session of different intensity aerobic exercise on inhibition control and food decision making in obese patients with restrictive diet failure and the neural mechanism of this process.In this study,a 2×2 complete experimental design was adopted,and 30 college students were selected through the scale,among which 22 completed the experiment.Stop eating within 3 hours before the start of the experiment,and drink 200 ml list oatmeal with the same calories 30 minutes before the start of the experiment.Pre-test was carried out,followed by a single medium and high intensity aerobic exercise intervention,and finally,post-test was carried out.The experiment tasks were to use the Go/Nogo task to measure inhibition control ability,and the food decision task to measure the food decision.Functional near infrared spectroscopy(f NIRs)was applied to monitor brain activation.The experimental data processing results showed that the correct rate of Nogo stimulation response increased significantly in the food picture Go/Nogo task in obese subjects who failed after a single medium and high intensity aerobic exercise,and decreased significantly in the Go stimulation response.The left frontal pole region(L-FPA)and left dorsolateral prefrontal lobe(L-DLPFC)were significantly activated.The correct rate of unhealthy food decision making was significantly increased in the obese subjects with restricted diet who failed after a single medium and high intensity aerobic exercise,and the time of unhealthy food decision making was significantly reduced.The right frontal pole region(R-FPA)and right dorsolateral prefrontal lobe(R-DLPFC)were significantly activated.This study found that a single session of medium and high intensity aerobic exercise could positively influence the inhibition control of obese people who failed restrictive diet,and there was no significant difference in the effect.Both medium-intensity aerobic exercise and high-intensity aerobic exercise can positively affect the food decision of obese people who fail restrictive diet,and there is no significant difference in the effect.Inhibition control plays a mediating role in the improvement of food decision-making process of obese people who fail restrictive diets with a single session of medium and high intensity aerobic exercise.
