Purpose: Through investigation and research on the physical condition of recruits,grasp the physical status of recruits in the armed police force,deeply analyze the impact of basic military training on the physical fitness of recruits,and provide references for further improving the training model of recruits and enhancing the effectiveness of new training.Method: 87 recruits enlisted in the autumn of 2019 were selected and classified according to physical shape index,physical function index and physical fitness index.The physical condition of the recruits before and after intensive basic military training was measured and compared.In addition,a comparative analysis will be made between the physical condition of the recruits before the training and the national physical fitness test results of the same age group,and the physical status of the recruits after the training will be compared with the physical fitness measurement results of veterans who have been enlisted for two years or more.Results: 1.In terms of body shape,compared with the national physical fitness monitoring results of the same age group,there is no significant difference between the recruits and the nationals of the same age group in terms of height,weight and bust circumference(P>0.05);after three months In intensive military training,the height of recruits increased(P<0.01),skinfold thickness,body fat percentage and body fat content of the humerus and scapula were significantly reduced(P<0.01),waist circumference was slightly reduced(P<0.05),and thin Weight gain(P<0.01),body density increased significantly(P<0.01),when there were no significant changes in body weight,bust,hip,BMI,Verwick index,waist-to-hip ratio and Erisman index(P> 0.05);After training,the thickness of the humerus skinfold and body fat rate of recruits were higher than that of veterans,and their body density was lower than that of veterans(P<0.05).There was no significant difference between other indicators and veterans(P>0.05).2.In terms of physical function,the resting heart rate,systolic blood pressure,diastolic blood pressure and vital capacity of the recruits were significantly higher than those of the nationals of the same age(P<0.01);after training,the resting heart rate of the recruits decreased(P<0.01)and the systolic blood pressure increased(P<0.01),while the diastolic blood pressure did not change significantly(P>0.05),the pulse pressure difference increased(P<0.01),vital capacity,vital capacity/body mass index increased significantly(P<0.01),Blanche heart function index Significantly lower(P<0.01);the resting heart rate of recruits after training was significantly higher than that of veterans(P<0.01),and there was no significant difference in physical function indicators such as vital capacity and vital capacity/body mass index from those of veterans(P>0.05).3.In the physical fitness indicators,the grip strength and pull-up indicators of recruits and nationals of the same age have no significant difference(P>0.05),but the flexibility is poor,which is significantly lower than that of nationals of the same age(P<0.01);recruits after training The performance of left and right hand grip,pull-ups,push-ups,sit-ups,and parallel bars arm flexion and extension have been significantly improved(P<0.01),sitting body forward bending performance has been improved(P<0.01),and 3000 m performance has been gradually improved(P< 0.01);After training,the recruits' left and right hand grip strength,3000-meter run,pull-ups,push-ups,sit-ups,and parallel bars were significantly lower than the veterans(P<0.01).Conclusion: There is little difference in physical condition between recruits and nationals of the same age group.Concentrated basic military training can promote and improve the physical shape,physical function and physical fitness of recruits,but there is still a certain gap with veterans.
