The validity and reliability of an integrated approach for quantifying match physical-tactical performance

Area of Science:

• Sports Science
• Football Performance Analysis
• Biomechanics

Background:

• Quantifying physical-tactical performance in football is complex.
• Existing methods may lack comprehensive validity and reliability.
• Understanding elite player intensity during tactical actions is crucial for training.

Purpose of the Study:

• To develop and validate an integrated approach for quantifying physical-tactical performance in football.
• To assess the reliability of this novel quantification method.
• To correlate novel high-intensity running data with commercial provider data.

Main Methods:

• Developed an integrated approach for physical-tactical performance quantification.
• Validated the approach using UEFA-qualified coaches and analysts (n=30).
• Assessed inter- and intra-observer reliability using kappa statistics on an English Premier League match.

Main Results:

• High validity demonstrated (91.8% correct responses overall).
• Strong inter-observer (κ=0.81) and almost perfect intra-observer (κ=0.94) reliability.
• Near-perfect correlation (r=0.99) between novel and commercial high-intensity running data.

Conclusions:

• The integrated approach is a valid and reliable tool for quantifying physical-tactical performance in football.
• This method enables the identification of unique high-intensity player profiles linked to tactical actions.
• Findings can enhance coaches' understanding and application of physical metrics in training.
