【摘要】：目的 :调查研究集训后期新兵的体格、体能及其相互关系 ,为其体质评价提供科学依据。方法 :用常规法测量 35 4名新兵的身高、体重、身体四个部位的围度、三个部位的皮褶厚度 ,并计算体重指数 (BMI)、上臂肌围、体脂率及去脂体重等 ;采用踏梯运动试验法测量 2 4 4名新兵的PWC170 和VO2max。结果 :(1)统计描述了新兵 14项体格指标和 2项体能指标的均值、标准差、最大和最小值、以及百分位数 ,为体格体能评价提供了参考值。 (2 )新兵中BMI正常和超重的人数分别占 84 .5 %和 10 .7% ,瘦弱和肥胖者分别占 4 .2 %和 0 .6 % ;上臂肌围正常者占 70 .3% ,肌消瘦者 2 9.6 %、多属轻度 ;PWC170 和VO2max在良好以上者分别占 76 .0 %和 86 .1% ,未发现体能很差的新兵。 (3)BMI与体重、上臂围、上臂肌围和胸围的r分别为 :0 .815、0 .730、0 .6 70、和 0 .6 48(P 0 .0 1) ;PWC170 与VO2max的r为 0 .837(P 0 .0 1) ,体脂率与三个部位皮褶厚度也显著相关 ;对体能与体格各指标进行了逐步回归分析。 (4)BMI低于正常的新兵 ,其PWC170 为 (10 98± 176 .2 )kg·m·min- 1,明显低于正常的 (132 8± 2 34.5 )kg·m·min- 1,(P 0 .0 1) ;细长体型组的PWC170 为(12 0 3± 2 17.8)kg·m·min- 1,低于匀称组 (1331± 2 2 9.6 )kg
[Abstract]:Objective: to investigate the physique, physical fitness and their relationship of recruits in the later period of intensive training, and to provide scientific basis for their physique evaluation. Methods: the height, weight, circumference of four parts of body, skinfold thickness of three parts were measured by routine method, and the body mass index (BMI),) of upper arm muscle circumference, body fat rate and fat-free body weight were calculated. Measurement of PWC170 and VO2max. in 244 recruits by treadmill exercise test Results: (1) the mean, standard deviation, maximum and minimum values and percentiles of 14 physical indexes and 2 physical fitness indexes of recruits were statistically described, which provided reference values for physical fitness evaluation. (2) among the recruits, 84.5% and 10.7% of the recruits were normal and overweight with BMI, 4.2% and 0.60% were thin and obese, and 70.3% were normal in the upper arm muscles. 29.6% of them were muscle emaciation, 76. 0% of mild PWC170 and 86. 1% of VO2max were above. No recruits with poor physical ability were found. (3) the r of BMI and body weight, upper arm circumference, upper arm muscle circumference and chest circumference were 0. 837 (P < 0. 01), 0. 837 (P < 0. 01), r = 0. 837 (P < 0. 01), respectively, and 0. 648 (P < 0. 01). Stepwise regression analysis was carried out on the indexes of physical fitness and physique. (4) the PWC170 of recruits with BMI was (1098 卤176.2) kg m min- 1), significantly lower than that of normal recruits (132.8 卤2.34.5) kg m min- 1, P < 0.01), and the PWC170 of slender group was (12.03 卤2.17.8) kg m min- 1) lower than that of symmetrical group (1331 卤2.29.6) kg.
