Exertional rhabdomyolysis is a pathologic muscle breakdown associated with strenuous physical activity. A largely preventable condition, it persists as an occupational hazard of military training and operations, especially in high heat environments among individuals pushing their endurance limits. A total of 464 cases of exertional rhabdomyolysis were identified in 2024, corresponding to a crude incidence rate of 35.9 cases per 100,000 person-years, and is the lowest case count recorded during the 2020-2024 period of surveillance. The 2024 case numbers demonstrated a 9.6% reduction from the peak rate in 2023, and the proportion of 39.7% hospitalized in 2024 represented a 4.0% decrease from 2023. In 2024, all services, excepting the Navy, showed declines in incidence rates, ranging from 2.0% in the Coast Guard to 29.1% in the Air Force, compared to 2023. Consistent with prior reports, subgroup-specific crude rates in 2024 were highest among men, those less than 20 years old, non-Hispanic Black service members, Marine Corps or Army members, and those in combat-specific or 'other' military occupations. Recruit trainees continued to experience the highest rates of exertional rhabdomyolysis in 2024, with a rate more than 13 times greater than officers and enlisted members. During the 2020-2024 surveillance period, 2024 evinced the lowest incidence rate of exertional rhabdomyolysis, nearly 10% lower than the peak observed in 2023. The Air Force showed the largest reduction, with incidence rates decreasing approximately 30% from the previous year.
运动性横纹肌溶解症是一种与剧烈体力活动相关的病理性肌肉分解。这是一种在很大程度上可预防的病症，但它仍是军事训练和行动中的职业危害，尤其是在高温环境下，对于那些挑战耐力极限的人来说。2024年共确诊464例运动性横纹肌溶解症病例，粗发病率为每10万人年35.9例，这是2020 - 2024年监测期间记录的最低病例数。2024年的病例数较2023年的峰值下降了9.6%，2024年住院病例的比例为39.7%，较2023年下降了4.0%。与2023年相比，2024年除海军外的所有军种发病率均有所下降，降幅从海岸警卫队的2.0%到空军的29.1%不等。与先前报告一致，2024年特定亚组的粗发病率在男性、年龄小于20岁者、非西班牙裔黑人军人、海军陆战队或陆军成员以及从事特定作战或“其他”军事职业的人员中最高。新兵学员在2024年继续经历最高的运动性横纹肌溶解症发病率，其发病率比军官和士兵高出13倍多。在2020 - 2024年监测期内，2024年运动性横纹肌溶解症的发病率最低，比2023年观察到的峰值低近10%。空军的降幅最大，发病率较上一年下降了约30%。
