The Claim
A PCA-derived physiological stress index combining creatine kinase and EWMA of session-RPE discriminates between overload and deload microcycles in elite U20 basketball players with high sensitivity, showing a 2.1-fold increase in mean score during overload (515 vs. 250 units).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A mathematical index based on muscle damage markers and perceived exertion scores reliably distinguishes between high-intensity and recovery training phases in elite U20 basketball players, with scores 2.1 times higher during high-intensity phases.

Intense basketball training tears muscle fibers, releasing an enzyme into the blood, while the brain senses growing fatigue from physical strain and reports it as effort. These two signals—blood enzyme levels and perceived fatigue—combine to form a clear measure of how much stress the body is under, which rises sharply during heavy training and stays low during recovery.
What the research says
1 studyScientists created a simple score using how sore players feel and a blood marker of muscle stress, and it worked perfectly to tell apart tough training weeks from easy recovery weeks in young pro basketball players.
