Abstract:
Objective To observe the physical development indexes of students from a teenager aviation school and to find out about the trainees′characteristics of physical development in order to advise on medical selection of teenager flying cadets and improve the present training programs .Methods Four hundred and thirty six students Grade 2015 were selected as subjects .The data of their physical examinations between school selection examination and annual examination were compared via matched-pair design.Physical growth and development of students in the aviation school were analyzed . Results The height, relative body mass and body mass index (IBM) of the students changed significantly (P<0.05) after one-year training in the youth aviation school .The proportion of students whose body mass accounted for 85% to 120%of standard weight was increased from 84.40%to 93.12%.94.74%of the increase came from students who used to be underweight .The qualified rate of students who reached the 70%-79% of the standard relative body mass in school selection examination was 57.14%.The reached qualified rate of students who reached the 80%-84% of the standard relative body mass in school selection examination was as high as 95.65%.The average height growth of the students was about 2.0 cm in the previous year .Conclusion The relative body mass of students who reached the 70%-85% of the standard relative body mass in school selection examination improved obviously ,suggesting that we should revise the weight standard to less than 30% of the standard weight , which conforms to the objective law of growth and development of adolescents .The rate of development of adolescent height requires further follow-up observation .All the students of a teenager aviation school should pay attention to a reasonable diet , take more physical exercise and monitor body mass .
