It is now well known that hemostasis is directly involved in the benefits induced by physical activity. It has recently been shown that the baseline mean platelet volume (MPV) may be a predictor of endurance performance. We aimed to explore whether platelet parameters are associated with VO2max as well as running duration and speed in a short-duration exhaustive exercise test. Thirty healthy male subjects (10 sedentary and 20 trained) performed an incremental running test until exhaustion. MPV, platelet distribution width (PDW), platelet (Plt) count, and plateletcrit (Pct) were determined before exercise, immediately after exercise and after 30' recovery. Training status did not produce any difference in the baseline levels or in the post-exercise increases found in all the parameters tested. VO2max, test duration, and running speed were not correlated with any baseline parameter. Although MPV was found to be a predictor of endurance performance in long-duration exercise, the results of the present study are consistent with the hypothesis that MPV may not be a significant marker of performance in short-duration exhaustive exercise. Likewise, more research is needed to ascertain whether platelet activation is a reliable performance predictor in other exercise settings.
现在众所周知，止血直接参与了体力活动带来的益处。最近有研究表明，血小板平均体积（MPV）基线值可能是耐力表现的预测指标。我们旨在探索血小板参数是否与最大摄氧量（VO2max）以及短时间力竭运动测试中的跑步持续时间和速度有关。30 名健康男性受试者（10 名久坐者和 20 名训练者）进行了递增跑步测试直至力竭。在运动前、运动后即刻和 30 分钟恢复后测定血小板平均体积（MPV）、血小板分布宽度（PDW）、血小板计数（Plt）和血小板压积（Pct）。基础水平或所有测试参数的运动后增加，训练状态都没有产生任何差异。VO2max、测试持续时间和跑步速度与任何基线参数均无关。虽然 MPV 被认为是长时间运动耐力表现的预测指标，但本研究结果与以下假设一致，即 MPV 可能不是短时间力竭运动中表现的重要标志物。同样，需要更多的研究来确定血小板激活是否是其他运动环境中可靠的表现预测指标。
