Whole body energy expenditure and lipid oxidation (Lox) are upregulated during and after exercise. Persons with spinal cord injury (SCI) generally have a blunted ability to utilize fat during exercise, but it is unknown if their substrate partitioning is affected during recovery from exercise.
To determine the effect of a single session of upper body circuit resistance exercise (CRE) on energy expenditure and Lox during exercise recovery in persons with and without SCI.
Twenty four persons (3 groups; 7 male and 1 female per group) without paralysis (neurologically intact; N) or with chronic (≥ 1 yr) paraplegia (P) or tetraplegia (T) participated. Energy expenditure and substrate partitioning were assessed via indirect calorimetry before, during, and three times after (up to 120 min after) a single session of CRE, or time-matched seated control (CON).
During CRE, all groups experienced a similar relative increase in oxygen consumption (49 ± 13, 55 ± 11, and 48 ± 15% VO for N, P, and T, respectively). The Post energy expenditure was greater following CRE vs. CON (P < 0.01) and independent of injury characteristics (10.6, 22.6, and 14.3% higher than CON for N, P, and T; P = 0.21). The absolute increase in Lox above CON during recovery was similar for N, P, and T (5.74 ± 2.81, 6.62 ± 3.10, and 4.50 ± 3.91 g, respectively; P = 0.45).
Energy expenditure and lipid utilization was increased similarly following circuit exercise in persons without and with spinal cord injury in a manner independent of level of injury.
全身能量消耗和脂质氧化（Lox）在运动中和运动后都会增加。脊髓损伤（SCI）患者在运动中通常无法有效地利用脂肪，但尚不清楚他们的底物分配在运动恢复期间是否受到影响。
确定单次上半身循环阻力运动（CRE）对无 SCI 和有 SCI 患者在运动恢复过程中能量消耗和 Lox 的影响。
24 名参与者（3 组；每组 7 名男性和 1 名女性），无瘫痪（神经完整；N）或慢性（≥1 年）截瘫（P）或四肢瘫痪（T）。通过间接测热法在单次 CRE 之前、期间和之后三次（运动后 120 分钟内）或时间匹配的坐姿对照（CON）评估能量消耗和底物分配。
在 CRE 期间，所有组的耗氧量都有相似的相对增加（N、P 和 T 组分别为 49±13%、55±11%和 48±15%VO）。与 CON 相比，POST 能量消耗更高（P<0.01），且与损伤特征无关（N、P 和 T 组分别比 CON 高 10.6%、22.6%和 14.3%；P=0.21）。在恢复期间，与 CON 相比，N、P 和 T 组的绝对 Lox 增加量相似（分别为 5.74±2.81、6.62±3.10 和 4.50±3.91 g；P=0.45）。
在无 SCI 和 SCI 患者中，运动后能量消耗和脂肪利用率增加相似，与损伤水平无关。
