Duchenne Muscular Dystrophy (DMD) is one of the most frequent childhood dystrophies, affecting cardiopulmonary functions and walking ability. One of the main symptoms is fatigue, which is caused by altered muscle metabolism related to energy expenditure (EE). Aquatic physiotherapy is a therapeutic modality that facilitates the maintenance of this posture because of immersion on the body. This cross-sectional observational study aimed to compare the EE on the ground and water of individuals with DMD through oxygen consumption in the maintenance of sitting posture. The individuals were in a sitting position on the ground and in the water for 20 min for the assessments. The variables peripheral oxygen saturation, heart rate, maximum expiratory pressure, maximum inspiratory pressure, forced vital capacity, respiratory quotient (RQ), and oxygen consumption per kilogram of body weight (VO /kg) were compared, adopting a significance of 5 % No difference was found between medians and quartiles of RQ when comparing the two environments. The same was observed for VO /Kg values on the ground and in water. The data from this study demonstrate that the EE of individuals with DMD did not change when maintaining a sitting posture on the ground and in water.

杜氏肌营养不良症患者地面坐姿和水中坐姿的能量消耗比较

杜氏肌营养不良症 (DMD) 是最常见的儿童营养不良症之一，影响心肺功能和行走能力。主要症状之一是疲劳，这是由与能量消耗 (EE) 相关的肌肉代谢改变引起的。水中物理疗法是一种通过浸入身体来促进保持这种姿势的治疗方式。这项横断面观察研究旨在比较 DMD 患者在维持坐姿时通过耗氧量在地面和水中的 EE。受试者在地面和水中保持坐姿 20 分钟进行评估。比较变量外周血氧饱和度、心率、最大呼气压力、最大吸气压力、用力肺活量、呼吸商（RQ）、每公斤体重耗氧量（VO/kg），采用5%显着性无比较两种环境时，发现 RQ 的中位数和四分位数之间存在差异。地面和水中的 VO /Kg 值也观察到了同样的情况。这项研究的数据表明，DMD 患者在地面和水中保持坐姿时，EE 没有变化。
