We examined, within the middleweight class, the relationship between ranking in boxing competition performance and some physiological factors.
Eight elite Italian amateur boxers (first series of AIBA ranking) were assessed in 2 testing sessions, a week apart. In the first testing session all subjects underwent anthropometric measurements from which body fat percentage, upper arm and forearm muscle cross-sectional areas were estimated. In the second testing session all subjects performed grip strength measures and a maximal treadmill test to assess oxygen consumption (VO2), blood lactate and heart rate at maximal effort, at individual anaerobic threshold, and at individual ventilatory threshold. The athletes were ranked following the criteria of world amateur AIBA ranking. In this ranking the first ranked boxer had the highest score gained participating in international tournaments.
A Spearman rho correlation analysis revealed that the VO2 at individual anaerobic threshold (46.0+/-4.2 ml x kg(-1) x min(-1), r=0.91) and the hand-grip strength (58.2+/-6.9 kg, r=0.87) were highly related (p<0.01) to boxing competition ranking. VO(2max) (57.5+/-4.7 ml x kg(-1) x min(-1), r=0.81) and wrist girth (17.6+/-0.6 cm, r=0.78) were moderately (p<0.05) related.
These data suggest that there are two basic factors related to boxing performance: physical fitness as indicated by individual anaerobic threshold and maximal oxygen consumption, and upper-body muscular strength as indicated by hand-grip strength.
我们在次中量级拳击比赛中，研究了比赛成绩排名与一些生理因素之间的关系。
八名意大利精英业余拳击手（国际拳击协会排名第一组）在相隔一周的两次测试中接受评估。在第一次测试中，所有受试者都接受了人体测量，据此估算体脂百分比、上臂和前臂肌肉横截面积。在第二次测试中，所有受试者都进行了握力测量和最大跑步机测试，以评估最大努力、个体无氧阈和个体通气阈时的耗氧量（VO2）、血乳酸和心率。运动员按照国际业余拳击协会的排名标准进行排名。在这个排名中，排名第一的拳击手在国际比赛中获得的分数最高。
Spearman等级相关分析显示，个体无氧阈时的VO2（46.0±4.2 ml·kg-1·min-1，r = 0.91）和握力（58.2±6.9 kg，r = 0.87）与拳击比赛排名高度相关（p<0.01）。最大摄氧量（VO2max）（57.5±4.7 ml·kg-1·min-1，r = 0.81）和腕围（17.6±0.6 cm，r = 0.78）呈中度相关（p<0.05）。
这些数据表明，与拳击表现相关的有两个基本因素：个体无氧阈和最大摄氧量所体现的身体素质，以及握力所体现的上身肌肉力量。
