The aim was to assess the relationship between aerobic fitness and metabolic power metrics in elite male soccer players, and the possible differences that playing positions might impose during match play over new metabolic power metrics. Sixty-two elite professional male soccer players (13 central backs, 13 side backs, 22 midfielders, and 14 forwards) took part in the study. Players were monitored during eleven months of full training (including pre-season and in-season) and over all official matches (Serie A matches, Italy Cup matches). Aerobic fitness tests were conducted one week after the start of the preseason, and 8, 24 and 36 weeks after the beginning of the Championship. Players' aerobic fitness and metabolic power metrics were considered as the mean of all seasonal testing and of pooling data of 38 championship matches and 3 or 6 Italy Cup matches for all the calculations respectively. The velocity at 4 mmol·L (VL) was significantly related to metabolic power metrics match variables with correlation ranging from trivial to very large (r = 0.32 to r = 0.89). Receiver-operating-characteristic (ROC) analysis showed that speed at VL was sensitive in detecting high metabolic power distance (HMPD) changes in all but central back players as revealed by area under the curve (central back .78, 95%CI .47 to .95; full back .93, 95%CI .64 to 0.99; midfielder .88, 95%CI .67 to 0.98; forward .90, 95%CI .62 to 0.99). This study's findings provide further evidence for the ecological validity of aerobic fitness in elite male soccer players. Players having a HMPD cut-off equal to or higher than > 1450 m for central backs, > 1990 m for full backs, > 2170 m for midfielders and > 1670 m for forwards may be considered as possessing superior aerobic fitness status. In light of this study's findings, the VL test may be considered a valid test to evaluate meaningful information for direct generic aerobic training in soccer players.
本研究旨在评估精英男性足球运动员有氧适能与代谢功率指标之间的关系，以及比赛中不同位置球员在新的代谢功率指标方面可能存在的差异。62名精英职业男性足球运动员（13名中后卫、13名边后卫、22名中场球员和14名前锋）参与了本研究。在为期11个月的全面训练（包括季前赛和赛季中）以及所有正式比赛（意甲比赛、意大利杯比赛）期间对球员进行监测。在季前赛开始一周后，以及锦标赛开始后的第8周、24周和36周进行有氧适能测试。在所有计算中，球员的有氧适能和代谢功率指标分别被视为所有赛季测试的平均值以及38场锦标赛比赛和3场或6场意大利杯比赛数据汇总的平均值。4 mmol·L时的速度（VL）与代谢功率指标比赛变量显著相关，相关性范围从小到非常大（r = 0.32至r = 0.89）。受试者工作特征（ROC）分析表明，除中后卫外，VL速度在检测所有球员的高代谢功率距离（HMPD）变化方面具有敏感性，曲线下面积显示（中后卫.78，95%CI.47至.95；边后卫.93，95%CI.64至0.99；中场球员.88，95%CI.67至0.98；前锋.90，95%CI.62至0.99）。本研究结果为精英男性足球运动员有氧适能的生态效度提供了进一步证据。中后卫HMPD临界值等于或高于> 1450 m、边后卫> 1990 m、中场球员> 2170 m、前锋> 1670 m的球员可被视为具有卓越的有氧适能状态。鉴于本研究结果，VL测试可被视为评估足球运动员直接通用有氧训练有意义信息的有效测试。
