Summary
Mean platelet volume (MPV) before a half-marathon is linked to running performance in recreational runners. This finding suggests that platelet activity may influence endurance, offering new insights for middle-distance running.
Area of Science:
- Sports Science
- Hematology
- Exercise Physiology
Background:
- Running economy and middle-distance performance are influenced by physiological factors.
- Limited research exists on hematological predictors of running performance.
Purpose of the Study:
- To investigate the association between hematological parameters and middle-distance running performance in recreational runners.
Main Methods:
- 43 amateur runners completed a half-marathon (21.1 km) at 75-85% VO2max.
- Whole blood samples were collected pre- and post-run for hematological analysis.
Main Results:
- Lymphocytes and eosinophils decreased, while MCV, platelets, MPV, WBCs, neutrophils, and monocytes increased post-run.
- Univariate analysis showed associations between running time and pre/post-run hematological values.
- Multivariate analysis revealed that only pre-run Mean Platelet Volume (MPV) remained significantly associated with running time after adjustments.
Conclusions:
- Baseline MPV is significantly associated with running time in recreational runners.
- Hyperactive platelets may have pleiotropic effects on endurance performance.

The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
