Cellular Integrative Immune Markers in Elite Athletes

Area of Science:

• Sports Medicine
• Immunology
• Exercise Physiology

Background:

• Established clinical immune markers include neutrophil-lymphocyte-ratio (NLR), platelet-lymphocyte-ratio (PLR), and systemic immune inflammation index (SII).
• These markers have potential applications in monitoring elite athlete training and health status.

Purpose of the Study:

• To assess the correlation between integrative immune markers and athlete characteristics.
• To investigate the acute effects of maximal exercise on these immune markers in elite athletes.

Main Methods:

• Blood samples from 195 national Olympic squad athletes were analyzed for white blood cells, lymphocytes, and platelets.
• Immune markers (NLR, PLR, SII) were calculated and correlated with athlete characteristics and exercise performance.
• A subgroup analysis examined immune marker changes 1 minute post-exercise.

Main Results:

• An inverse correlation was observed between peak power output and SII/NLR levels.
• Higher aerobic fitness in athletes was associated with significantly lower SII and PLR values.
• Maximal exercise acutely elevated SII and reduced PLR.

Conclusions:

• Integrative immune markers show potential for monitoring training load and health status in elite athletes.
• NLR, PLR, and SII can provide insights into an athlete's physiological response to training and exercise stress.
