Abstract:
Objective To improve the load resistance ability of students in teenager aviation schools and carry out specialized training for the body situation and shape of students.Methods We selected students from 14 teenager aviation schools and measured their height,weight,and the circumferences of necks,chests,upper-arms,waists,hips,and thighs.We compared the data of these students from different areas and the parameters were analyzed statistically by correlation analysis.Results Totally 411 students from 6 southern schools and 403 students from northern schools were investigated.Their average body height,weight and body mass index (BMI) were (172.3 ± 4.39) cm,(62.7 ± 7.3) kg,and (21.1 ± 2.23)kg/m2 respectirely.Students from northern schools were taller and heavier than those from southern schools (P ＜ 0.05).There was no difference between students from northern and southern schools in BMI.Compared with the domestic average levels of height,weight and chest circumference of teenagers aged 14 to 17,students of teenager aviation schools were higher,but there was no difference in weight or chest circumference.The average circumferences of the chest,neck,left upper-arm,right upper-arm,waist,hip,left thigh and right thigh were (83.1 ± 5.06),(34.7 ±3.07),(25.2±2.33),(25.5 ±2.30),(73.4 ±6.73),(89.7 ±5.89),(50.1 ±5.22),and (50.2 ±5.27)cm,respectively.According to the data,students from northern schools had a bigger chest circumference and thigh circumference but a smaller neck circumference and upper-arms circumference than those from southern schools (P ＜ 0.05).The correlation coefficient between BMI and the circumferences of the chest,neck,left upper-arm,right upperarm,waist,hip,left thigh and right thigh was 0.2201,0.1066,0.2466,0.2499,0.2291,0.2149,0.2299,0.2264,respectively.All of them were statistically significant (P ＜ 0.0001).Conclusion Load resistance related parameters of students in teenager aviation schools are not different from the domestic levels,which points to the urgent need for load resistance ability training for these students.Some parameters vary between areas.BMI is positively related to those load resistance parameters.Based on regional variations and regularities found in this study,specialized load resistance ability training could be made more efficient.
