Many studies have reported that physical exercise can improve the levels of function, quality of life (QoL), and fatigue in patients with hematologic malignancies. However, exercises should be prescribed with caution in patients with thrombocytopenia to prevent exercise-related bleeding. Some studies have suggested threshold platelet counts at which physical exercise can safely be performed. Herein, we review the current literature to determine the platelet count thresholds and types of physical exercise that may be prescribed to reduce the risk of exercise-related bleeding in those with hematological malignancies while undergoing chemotherapy.

叙述运动对患有血液系统恶性肿瘤的血小板减少症患者进行体育锻炼是安全可行的。

许多研究报告说体育锻炼可以改善血液系统恶性肿瘤患者的功能水平，生活质量（QoL）和疲劳。但是，血小板减少症患者应谨慎地进行运动处方，以防止运动相关的出血。一些研究建议可以安全地进行体育锻炼的阈值血小板计数。本文中，我们回顾了当前的文献，以确定可以降低血小板计数阈值和体育锻炼类型的方法，这些方法可以降低患有血液系统恶性肿瘤而接受化疗的运动相关出血的风险。
