March myoglobinemia: a hazard to renal function

Area of Science:

• Sports Medicine
• Exercise Physiology
• Renal Function

Background:

• Military training involves intense physical exertion.
• Understanding the physiological impact of prolonged exercise on muscle and kidney health is crucial.

Purpose of the Study:

• To investigate the effects of prolonged military training on muscle damage markers and renal function in army recruits.

Main Methods:

• Measured serum muscle enzymes (creatinine phosphokinase, lactic dehydrogenase, SGOT) and myoglobin levels.
• Assessed renal function through urea, creatinine, uric acid levels, and creatinine clearance.
• Collected blood samples before training, and before and after each hike.

Main Results:

• Significant elevations in muscle enzyme levels and persistent myoglobinemia were observed throughout the training period.
• A statistically significant decrease in creatinine clearance was noted, with mean values dropping considerably after the final hike.
• These findings indicate substantial muscle damage and impaired renal function.

Conclusions:

• Prolonged physical exercise, like military training, induces significant muscular damage.
• Continuous muscle injury and persistent myoglobinemia pose a potential risk to renal function in physically active individuals.
