促进中小学生体脑协同发展的运动方案研发与实证研究OACHSSCD

Objective:To investigate the effects of a 12-week comprehensive exercise intervention on physical fitness and executive function in primary and secondary school students and the relationship between them,and to provide an effective program for physical-cognitive integration.Methods:A 12-week comprehensive exercise program was developed for primary and secondary school students respectively based on their physical-cognitive characteristics,and implemented with 544 students.Results:The intervention significantly improved physical fitness and executive function.Primary students improved in speed,explosive power,cardiorespiratory endurance,agility,coordination,inhibition,updating,and shifting.Middle school students improved in speed,explosive power,agility,coordination,inhibition,updating,shifting,as well as flexibility and strength endurance.Additionally,male students showed improvement in cardiorespiratory endurance.Updating gains in primary students were associated with agility and cardiorespiratory endurance,with agility showing a stronger association;shifting gains in middle school students were associated with agility.Conclusions and suggestions:The developed program effectively promotes coordinated physical and cognitive development,with agility as a core target.Future practice should employ agility via grade-level differentiated tasks and cognitively engaging complex situations under moderate-to-high intensity.
