Abstract：
UNASSIGNED: We sought to create a system to evaluate the physical fitness of outstanding Chinese male boxers that included an evaluation index, fitness level criteria, and modeling. This system was then used to assess athletes\' physical fitness and development.
UNASSIGNED: Documentation, expert interviews, questionnaires, measurements, and statistical analyses were used in this study.
UNASSIGNED: The physical fitness evaluation system included the following three components: (1) body shape indexes (n = 4) including the backhand upper arm circumference differential, finger span height, Cottrell index, and pelvic width/shoulder width × 100; (2) body function indexes (n = 4) including relative maximum anaerobic power, relative maximal oxygen uptake, and creatine kinase and testosterone concentrations; and (3) athletic quality indexes (n = 9) including the speed strength index, the backhand straight punch strength, 3-min cumulative punching force, backhand straight punch reaction time, backhand straight punch speed, 30-m sprint, 9-min double shake jump rope, 1-min double shake jump rope, and sitting forward bend tests. A five-point grading system to evaluate physical fitness was established and an evaluation model was proposed.
UNASSIGNED: The reference values were determined to be objective and effective using a back substitution process. Individual and differential assessments reflected the athletes\' level of physical fitness. The critical values were established under the best and worst conditions and the optimal values were found to be valid and effective.

摘要：
■我们试图创建一个系统来评估中国优秀男性拳击手的身体素质，其中包括一个评估指标，健身水平标准，和建模。然后，该系统用于评估运动员的身体素质和发育。
■文档，专家访谈,问卷，测量,并在这项研究中使用统计分析。
■身体素质评估系统包括以下三个组成部分：（1）身体形状指数（n=4）包括反手上臂周长差，手指跨度高度,科特雷尔指数，和骨盆宽度/肩宽×100；（2）身体功能指标（n=4），包括相对最大无氧功率，相对最大摄氧量,和肌酸激酶和睾丸激素浓度；（3）运动质量指标（n=9），包括速度强度指标，反手直拳的力量，3-min累积冲孔力,反手直拳反应时间,反手直冲速度,30米冲刺,9分钟双摇跳绳,1分钟双摇跳绳，和坐着向前弯曲测试。建立了评价身体素质的五点评分体系，提出了评价模型。
■使用反取代方法确定参考值是客观和有效的。个人和差异评估反映了运动员的身体素质水平。临界值是在最佳和最差条件下建立的，并且发现最佳值是有效的。
