Study On The Relationship Between Dietary Nutrition Structure And College Students Physical Fitness

Reasonable dietary structure is the basis for ensuring the reasonable intake of nutrients,and the reasonable intake of nutrients is an important guarantee for students' learning and growth.The university period is a special period of life development.At the same time,it is also a key stage for the development and development of theoretical knowledge,growth and development of college students.The nutritional status and physical quality of college students are related to the rise and fall of a nation,to the prosperity of a country,and the reasonable dietary structure to ensure physical health is particularly important.Objective:To investigate the dietary nutrition structure of college students in a college in Jilin Province,and to analyze the three aspects of physical health(physical health,physical function health,physical exercise ability and health),to evaluate the physical condition of college students in all aspects,and to explore possible Factors affecting college students' physical fitness,improve students' health awareness,guide the development of college students' dietary nutrition structure to a healthier and more reasonable proportion,change bad eating habits,develop healthy living habits,and finally improve their own health.purpose.At the same time,it provides a reference for the country to better formulate a healthy China development strategy.Methods:A total of 720 freshmen from a college in Jilin Province were selected.The 24 h dietary review method and KAP survey method were used to issue questionnaires.Through questionnaire survey,students' nutrient intake and eating habits were calculated,and dietary nutrition structure and meals were calculated.Energy supply ratio.At the same time,the college students' body mass index and related physical fitness measurement data were analyzed to understand the current situation of college students' physical fitness.The correlation between dietary nutrition structure and college students' physique was analyzed using IBM SPSS statistics 20,and the effect was evaluated.Result:1.The survey results show that students' knowledge,attitudes and behaviors are better,but some students lack a comprehensive understanding of basic nutrition knowledge,and the proportion of students with bad eating behavior is large.2.The survey results show that the overall nutritional status of the students is good,but most of the students have an unreasonable dietary structure,mainly due to the average daily intake of cereals and vegetables,followed by fruits,beans and milk.Classes and seafood products are the least.3.The survey results show that 1.Body shape,students' body mass index(BMI)is more standard,but girls have higher incidence of malnutrition and lower body weight;male overweight and obesity are more prominent.2.The physical function of the body,using the lung vitality measurement data for analysis,the overall performance of the students is better,the overall performance of boys is better than girls,the proportion of female students is not qualified.3.Physical condition,the overall situation of the students is better,among which,the sitting position is better than the 50-meter running,while the sit-ups/lead-up results are more general.4.Survey data show that energy,fat,protein,niacin,vitamin A,potassium and other nutrients are related to physical fitness indicators.Conclusion:1.Through analysis,the more the various nutrient intakes,the higher the BMI value.Overweight and obese students have a BMI value that is beyond the normal range,and has poor eating behaviors such as not eating breakfast,eating supper,partial eclipse,and eating fried barbecue food.Therefore,the intake of nutrients can directly affect the body shape indicators,but not as much as possible,the normality of BMI is closely related to whether the dietary nutrition structure is reasonable.A reasonable dietary nutrition structure can make the BMI value within the standard range.2.Through analysis,some nutrients are indeed related to the results of physical fitness measurement.Those with sufficient nutrient intake and reasonable dietary structure have relatively high BMI values,and body shape indicators and physical quality indicators tend to be optimal.Therefore,the intake of nutrients does not reflect the quality of the body.Only when the dietary structure is reasonable,sufficient nutrients are taken to make the students' body shape healthy,and then the body function and physical exercise ability are healthy,so as to be overall.Improve the health of students' physique.
