This study aimed to: (1) develop an integrated approach to quantifying match physical-tactical performance and (2) comprehensively examine the validity and reliability of this novel approach. Both UEFA qualified coaches and performance analysts ( = 30) participated to verify the scientific robustness of this new method. The percentage of correct responses were used to verify the validity of the integrated approach and the minimum acceptable agreement was set at 80%. Two well-trained groups of observers analysed a randomly selected English Premier League match for inter- and intra-observer reliability using the kappa statistic. A high degree of validity was demonstrated as the mean percentage of correct responses by all participants, accounting for 91.8 ± 4.3% for all, 92.2 ± 4.7% for out-of-possession, and 91.6 ± 5.7% for in-possession physical-tactical variables. Inter- and intra-observer reliability were found to be strong (κ = 0.81) to almost perfect (κ = 0.94), respectively. Additional analyses demonstrated that there was a nearly perfect correlation between data derived from the novel filter used for the present study to capture high-intensity running and those obtained from the filter of the commercial data provider ( = 0.99; < 0.01). The data demonstrates that the integrated approach is valid and reliable regarding the quantification of physical-tactical performances. Therefore, it is now possible to unveil unique high-intensity profiles of elite players related to key tactical actions. This may help coaches and practitioners better understand the physical-tactical performances of players, as well as effectively translate physical metrics into training.
（1）开发一种综合方法来量化比赛中的身体战术表现；（2）全面检验这种新方法的有效性和可靠性。30名欧足联资格教练和表现分析师参与其中，以验证这种新方法的科学稳健性。正确回答的百分比用于验证综合方法的有效性，最低可接受一致性设定为80%。两组训练有素的观察员使用kappa统计量分析了一场随机选择的英超比赛，以检验观察者间和观察者内的可靠性。所有参与者的正确回答平均百分比显示出高度有效性，所有身体战术变量的平均百分比为91.8±4.3%，无球时为92.2±4.7%，有球时为91.6±5.7%。观察者间和观察者内的可靠性分别很强（κ = 0.81）到几乎完美（κ = 0.94）。进一步分析表明，本研究用于捕捉高强度奔跑的新型过滤器得出的数据与商业数据提供商过滤器获得的数据之间存在近乎完美的相关性（r = 0.99；P < 0.01）。数据表明，综合方法在量化身体战术表现方面是有效且可靠的。因此，现在有可能揭示与关键战术行动相关的精英球员独特的高强度表现特征。这可能有助于教练和从业者更好地理解球员的身体战术表现，并有效地将身体指标转化为训练内容。
