| With the continuous development of our economic andcomprehensive national strength， the National Fitness supported andconcerned by the community entered the people’s vision gradually. Whenvigorously promoting the National Fitness, enhancing people’s health andthe development of health’ s science and technology has become apriority at the same time. More and more disciplines pay their attention tothe effects of exercise on various aspects of the human being. Nowadays,the definition of health has not only limited to enhancing physical health,but more to promoting both physical and mental health. Therelationship between body and mental is closely and inextricably linked.Physical exercise on human health has a positive effect. Researchs onphysical exercise are more diverse. In recent years, studies about theimpact of exercise on mental activity have went into people’s sight.Moreand more scholars pay their attention to the research on the relationshipbetween exercise and cognitive psychology. Most studies show a positiverole in promoting sport for cognition, emotion, emotions and otheraspects of cognitive.However, there is little quantitative research betweensports and working memory. There’s little research on the impact ofexercise on working memory, and quantify is not stringent enough, so the conclusion is not consistent. Existing studies mostly focused on therelationship between emotion and motion studies,as well as sports andexercise on cognitive decline in the elderly and other aspects, but theinfluence of exercise on cognitive function is still relativelysmall.Therefore, based on the above, we attempts to explore therelationship between movement and working memory in the presentstudy.So, based on the framework of the movement promotingawareness,this study used he paradigm of continuous operation with abreadth of tasks and de-de-de breadth task, to discuss the effects ofworking memory span after adding motion processing in differentcognitive load conditions.This study randomly selected a total of60subjects(40undergraduates from Inner Mongolia Normal University and20undergraduates from Inner Mongolia University of Technology).Allsubjects were randomly divided into six groups(2for control groups and4for experimental group). The control group consisted of high cognitiveload and low cognitive load, and every group has10subjects.Theexperimental groups were middle exercise intensity--high cognitive load,middle exercise intensity--low cognitive load, low exerciseintensity--high cognitive load, low exercise intensity--low cognitive load.All subjects firstly completed the pre-measured of working memory span.Then, the control groups had a20min rest; the experimental groups completed the followed sporting as the same total time as the controlgroups. In this study, moderate-intensity exercise is150to160beats/min of the exercise heart rate; exercise heart rate is120to130beats/minfor the small-intensity exercise. When subjects’ heart rate achieve therequired interval, we start counting and subjects were asked to sport15minutes.After the sporting, subjects returned to the laboratory to test theworking memory span again. The studies have shown that:1. After passing motion processing, the difference of scores betweenthe pre-measured of working memory span and post-test of workingmemory span was significant.Analysis of variance showed that the maineffect of Exercise intensity was significant.That is to say,exercisepromoted the score on working memory span.2. Whether in low cognitive load groups or in a high cognitive loadgroup, the score of Moderate-intensity exercise groups were significantlybetter than the performance of small intensity exercise group.The resultsillustrated that the movement of moderate-intensity exercise plays agreater role in promoting working memory span than the small-intensityexercise.3. The main effect of cognitive load on working memory span issignificant.The difficulty of the task is illustrated in a significant impacton the working memory. The task more difficult and more complex,theperformance of working memory span is worse. 4. Analysis of variance showed that exercise intensity and cognitiveload interaction were not significant, meaning that there is no interactionbetween the two. |
