Research On The Relationship Between Physical Activity, Aerobic Fitness And College Students' Attention To Network Function

Objective:College students are the backbone of the future social development,their physical and mental development is widely concerned by all walks of life.Attention is the core function of cognitive system.It refers to the cognitive process of preparing and dealing with some aspects of external physical environment or subjective memory storage.It is the orientation and concentration of psychological activities to certain objects.Attention to the development of function will damage the overall cognitive level of adolescents,affect their learning quality,serious will also cause a series of behavioral disorders,conduct problems and so on.Studies have shown that exercise can improve and promote the development of adolescent attention function.But the pathway of physical activity to attention function is unclear.Therefore,this study explored the relationship between physical activity and attention function of college students through investigation,and further explored the approach of physical activity affecting attention function through aerobic fitness by means of intermediary model.It provides a theoretical and practical basis for promoting the attention function of college students through physical activity.Method:Using the convenient sampling method,111 freshmen were selected from Yangzhou University as the research object.The physical activity,physical fitness and attention function of the college students were measured.The physical activity level of college students was measured by the International physical activity questionnaire(Chinese version),the physical fitness level of college students was evaluated by means of physical fitness measurement,and the three network functions of college students' attention were measured by the attention function test software ANT.The collected data are processed by EXCEL?SPSS22.0 and AMOS software.Results:(1)There was significant difference in physical activity level between male and female(t=4.210,p<0.01),and there was significant difference in aerobic fitness between sexes(t=5.991,p<0.01).There was no significant difference in gender(t=1.588,p>0.05)in the alerting network function of the attention network,but there was no significant difference in the orientation network function of the attention network in the gender(t=1.373,p>0.05),and there was no significant difference in the function of the attention network in gender(t=1.588,p>0.05).There was no significant difference in the function of executive control network between the two sexes(t=-0.828,p>0.0 5)(2)There was a significant correlation between physical activity and alert network function(r=0.297,p<0.01),and between physical activity and directed network function(r=0.213,p<0.05).There was also a significant correlation between physical activity and executive control network(r=-0.237,p<0.05).There was a significant correlation between aerobic fitness and alert network function(r=0.261 p<0.01),but no correlation between aerobic fitness and directed network(r=0.153,p>0.05),but no correlation between aerobic fitness and executive control network(r=0.153,p>0.05).There was a significant correlation between physical activity and aerobic fitness(r=-0.058,p>0.05),and a significant correlation between physical activity and aerobic fitness(r=-0.250,p<0.05).(3)fitness and alertness were correlated.The direct influence coefficient of physical activity on physical fitness was 0.250,physical activity on attention was 0.297,aerobic fitness on alertness was 0.199.The indirect influence coefficient of physical activity through aerobic fitness on alertness was 0.201.Conclusions:(1)Among the demographic variables of college students,physical activity and aerobic fitness had significant difference in gender,but attention function had no difference in gender.(2)The higher the level of physical activity,the better the attention network function;the higher the physical activity level,the better aerobic fitness;the better aerobic fitness,the better alert network function.(3)The physical activity of college students not only has direct influence on attention function,but also indirectly affects attention function through the influence of aerobic fitness.Aerobic fitness plays a part of intermediary role in the influence of physical activity on alertness.
