CrossFit is a high-intensity physical activity modality that, despite its numerous health benefits, poses a risk of exercise-related injuries. The rare but serious complication of exertional rhabdomyolysis is a good example. There are few case reports describing this condition, and to the best of the author's knowledge, this is the first published case of CrossFit-induced rhabdomyolysis reported in Brazil - one of the most influential countries in the world of CrossFit. Our case report describes a 45-year-old male, an experienced Level 2 CrossFit Coach, who presented with progressive upper limb pain and dark urine two days after a routine CrossFit workout. Physical examination revealed muscle stiffening and pain upon palpation. Laboratory tests showed significantly elevated creatine phosphokinase (CPK) levels (126.891 U/L) and abnormal values of lactate dehydrogenase, alanine aminotransferase, and aspartate aminotransferase. The patient was diagnosed with exercise-induced rhabdomyolysis and treated with aggressive intravenous and oral hydration, with complete clinical improvement by the fifth day of hospitalization. The patient was dismissed without any complications and with progressively decreasing levels of CPK, with ambulatorial follow-up arranged. CrossFit-induced rhabdomyolysis, although rare, represents an important health concern due to the possibility of severe systemic consequences. The present case highlights the importance of early detection and treatment of exertional rhabdomyolysis, even in well-conditioned athletes.
CrossFit是一种高强度的体育活动形式，尽管它有诸多健康益处，但也存在与运动相关的受伤风险。运动性横纹肌溶解这种罕见但严重的并发症就是一个很好的例子。描述这种病症的病例报告很少，据作者所知，这是巴西首例发表的由CrossFit引发的横纹肌溶解病例——巴西是CrossFit界最具影响力的国家之一。我们的病例报告描述了一名45岁男性，他是一名经验丰富的二级CrossFit教练，在一次常规CrossFit锻炼两天后出现进行性上肢疼痛和深色尿液。体格检查发现肌肉僵硬且触诊时有疼痛。实验室检查显示肌酸磷酸激酶（CPK）水平显著升高（126,891 U/L），乳酸脱氢酶、丙氨酸氨基转移酶和天冬氨酸氨基转移酶值异常。该患者被诊断为运动性横纹肌溶解，并接受了积极的静脉和口服补液治疗，住院第五天时临床症状完全改善。患者出院时无任何并发症，CPK水平逐渐下降，并安排了门诊随访。CrossFit引发的横纹肌溶解虽然罕见，但由于可能产生严重的全身后果，仍是一个重要的健康问题。本病例突出了即使在身体状况良好的运动员中，早期发现和治疗运动性横纹肌溶解的重要性。
