Early warning system for player recovery? A series of case studies illustrating the application of individualised adaptive reference ranges in the longitudinal blood monitoring of English Premier League soccer players

Human

2025 May

Doctors used a quick blood test to check a marker of inflammation in soccer players over time, and found it helped them spot when players were stressed or not recovering well. This means the test can be used to track player health during the season.
