Muscle cell leakage due to long distance training
Summary
Distance running and rowing can cause muscle damage, leading to abnormal myoglobinemia and free hemoglobin in plasma. Training can mitigate this exercise-induced muscle injury in healthy individuals.
Area of Science:
- Exercise Physiology
- Biochemistry
Background:
- Distance running and rowing are strenuous activities.
- Muscle damage can occur during intense physical exertion.
Purpose of the Study:
- To investigate exercise-induced muscle damage in runners and rowers.
- To assess the impact of training on muscle damage markers.
Main Methods:
- Blood samples were collected from runners and rowers post-exercise.
- Serum concentrations of myoglobin, free hemoglobin, and cellular enzymes were measured.
- Urine analysis was performed to detect proteinuria and casts.
Main Results:
- Abnormal myoglobinemia and free hemoglobin were detected in runners and rowers.
- Serum enzyme and metabolite levels increased post-exercise.
- Non-runners showed a higher myoglobin increase than runners.
- Three months of running training reduced muscle damage markers.
Conclusions:
- Exercise-induced myoglobinemia and transient rhabdomyolysis are common in endurance athletes.
- Training can significantly reduce exercise-induced muscle damage.
- No significant iron loss was observed in the urine.
