| Physical fitness can not only reflect the level of human life activities,but also an important aspect of measuring the physical exercise ability of human beings,and the excellent physical condition is of great significance for the healthy growth of individuals and the prosperity and progress of the country.As important promoters of sustainable social development,adults shoulder the important mission of national prosperity.The analysis of the physical condition of adults can not only understand the current physical condition of adults,but also have certain value for grasping the change trend of their physical fitness and promoting the development of adult physique.Based on this,in order to understand the physical fitness change trend of adults in Ningxia 20～59 and its future developme nt,this study is based on the report data of the Ningxia National Physical Fitness Monitoring Adult Module in 2000～2020,takes 2030 as the time cut-off point of prediction,and uses research methods such as literature method,Lagrange interpolation method and grey prediction method to quantitatively predict the future development of local adults on the basis of grasping the change trend of local adult physique.The study found that:(1)In terms of body shape:in 2000～2020,there was an age difference between the height of men and women in urban and rural areas in Ningxia,with the age group of 20～34 years old mainly increasing,and the age group of 35～59 years old mainly decreasing;Weight change is similar to height change,but the decrease trend of weight index in people aged 35～59 is not obvious;The change of BMI value was mainly increased;Changes in waist and hip circumference are predominantly increased;The change in WHR value is mainly increased.It is expected that by 2030,the changes in height,weight,waist circumference,hip circumference,BMI value and WHR value of men and women in urban and rural areas in Ningxia will mainly increase,and at the same time,the nodes of BMI value>24.0,female WHR value>0.85,and male WHR value>0.90 will shift to a smaller age group.(2)In terms of physical function:in 2000～2020,the changes in the venous beats of men and women in urban and rural areas in Ningxia were mainly increased,but remained in the normal range of 60～100 times/minute;Systolic blood pressure changes increased,diastolic blood pressure changes were mainly increased,and there was also a slight decrease in blood pressure over 35 years old,and blood pressure remained generally in the normal range of 140/90mmHg;Changes in vital capacity are predominantly decreasing.It is estimated that by 2030,the venous pulse and blood pressure of men and women in urban and rural areas of Ningxia will increase;Lung capacity was mainly reduced,but the rural population was mainly increased.(3)In terms of physical fitness:in 2000～2020,the grip strength of men and women in urban and rural areas in Ningxia will mainly decrease;When selecting the reaction,the main thing is to increase;There were differences between urban and rural areas in the anterior flexion of the sitting body,with the urban population mainly increasing and the rural population mainly decreasing.Standing on one foot with eyes closed is mainly increased;The body mass index value of grip strength was mainly decreasing.It is expected that by 2030,the grip strength of men and women in urban and rural areas in Ningxia will decline;Increase when selecting a reaction;decreased body mass index value for grip strength;Forward flexion in the sitting body and standing on one foot with eyes closed were less predictive,so no prediction was made.Based on the above conclusions,the study recommends:(1)In order to cope with the adverse trend of physical shape development,individuals should develop a good lifestyle,reasonably control energy intake,and adhere to physical exercise activities to enhance their physical fitness;It is necessary for the relevant government departments to make overall scientific plans,actively publicize scientific sports and life concepts,increase health education for residents,and improve residents’ self-health awareness.(2)In order to cope with the adverse trend of physical function development,individuals should pay attention to it,establish a scientific lifestyle,cultivate good exercise habits,and reasonably choose endurance exercise items according to their own conditions;Relevant government departments should create a good atmosphere for social sports and promote more people to participate in physical exercise.(3)In order to cope with the adverse trend of physical fitness development,individuals should maintain a certain exercise intensity,duration and frequency of exercise according to their actual situation;Relevant government departments shall reasonably put in relevant quality exercise equipment and provide guidance on their use,regularly organize fitness activities,and encourage more residents to strengthen exercise activities. |
