CK Data Supplemental Material: Soccer Player Muscle Overload Monitoring

52 soccer players' creatine kinase concentrations were collected 24 to 48 hours after matches across six full seasons of the Brazilian championship. Alessandro Haupenthal published this dataset on figshare to investigate individualized threshold values for CK monitoring. The data includes CK concentrations from 20 matches and elements from the 5th matches' box plots used to determine individual reference thresholds.

Use Cases

• Determine individualized reference thresholds for creatine kinase based on the box plot elements mentioned in the description.
• Compare muscle overload detection using individual upper limits versus a recommended group-based cutoff value of 1270 U/L.
• Analyze CK concentration trends across six seasons of a soccer championship to assess player recovery patterns.

Strengths

• Data includes CK measurements from 52 players across six full seasons.
• Individualized reference thresholds are derived from elements of the 5th matches' box plots.
• Muscle overload detection is computed using both individual limits and a group cutoff of 1270 U/L.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal and geographic bias inherent to the Brazilian soccer championship.
