Recreational or regular physical and sport activities may be responsible for a wide range of cutaneous complications. Among them, "sports purpura" is a peculiar symptom that can occur during a large number of sports. "Effort purpura" defines any purpura occurring within the context of physical exercise irrespective of its cause. Therefore this clinical diagnosis includes various aetiologies. Diagnosis of traumatic purpura is often easy if the sport is mentioned in the anamnesis; cutaneous exercise - induced vasculitis must be also noted. Purpura can reveal systemic diseases or internal haemorrhage, such as spleen rupture, thrombopathies or systemic vasculitis, and other effort purpuras must be taken into account, including those related to the environment (cold, sun exposure...). Knowledge of a physical activity before the occurrence of purpura should be known by practitioner to avoid unnecessary and costly explorations in most of the cases.
娱乐性或常规的体育及运动活动可能会引发一系列皮肤并发症。其中，“运动性紫癜”是一种特殊症状，在大量运动过程中都可能出现。“用力性紫癜”指的是在体育锻炼过程中出现的任何紫癜，无论其病因如何。因此，这种临床诊断涵盖多种病因。如果在病史中提及了运动项目，外伤性紫癜的诊断通常较为容易；还必须注意皮肤运动诱发的血管炎。紫癜可能提示全身性疾病或内出血，如脾破裂、血小板病或系统性血管炎，同时还必须考虑其他用力性紫癜，包括与环境相关的紫癜（寒冷、日晒……）。医生应了解紫癜出现之前的体育活动情况，以便在大多数情况下避免进行不必要且费用高昂的检查。
