We recently demonstrated that upper-body rowing exercise (UBROW) improved aerobic fitness in individuals with spinal cord injury (SCI), with no effect on traditional cardiometabolic risk factors. Here, we tested the hypothesis that the exercise-induced increase in aerobic fitness was maintained at 6-month (6M) follow-up. Six-month follow-up. University/hospital. Seventeen wheelchair-dependent participants with SCI. 12-week of exercise training (UBROW) or control (CON). Aerobic fitness (PO and V̇O), body composition, blood pressure, and blood biomarkers of cardiometabolic risk were assessed at 6M follow-up and compared to baseline (BL) and immediately post-intervention (12-week). Minutes of mild, moderate, and heavy intensity leisure time physical activity (LTPA) were assessed by self-report. Fourteen participants returned at 6M follow-up (CON, = 6; UBROW, = 8). In UBROW, PO (median (Q1-Q3)) increased from BL (70 W (37-84)) to 12-week (77 W (58-109), P = 0.01) and 6M follow-up (81 W (51-96), P = 0.01), with no difference between 12-week and 6M follow-up (P = 0.21). Similarly, V̇O increased from BL (15.4 ml/kg/min (10.5-19.4)) to 12-week (16.6 ml/kg/min (12.8-21.3), P = 0.01) with no difference between 12-week and 6M follow-up (16.3 ml/kg/min (12.9-19.7), P = 0.74). No differences were found in CON for either PO (P = 0.22) or V̇O (P = 0.27). There were no changes over time in traditional cardiometabolic risk factors or for minutes of different LTPA intensities. We demonstrate that improvements in aerobic fitness are maintained for at least six months after completion of a 12-week exercise intervention, supporting the use of periodic exercise interventions to boost aerobic fitness level in individuals with SCI.

我们最近证明，上半身划船运动（UBROW）可以提高脊髓损伤（SCI）患者的有氧健身水平，而对传统的心血管代谢危险因素没有影响。在这里，我们测试了这样一个假设，即运动引起的有氧健身水平的提高在 6 个月（6M）随访时得以维持。6 个月随访。大学/医院。17 名依赖轮椅的 SCI 患者。12 周的运动训练（UBROW）或对照（CON）。在 6M 随访时评估有氧健身（PO 和 V̇O）、身体成分、血压和心血管代谢风险的血液生物标志物，并与基线（BL）和干预后即刻（12 周）进行比较。通过自我报告评估轻度、中度和重度强度休闲时间体力活动（LTPA）的分钟数。14 名参与者在 6 个月随访时返回（CON， = 6；UBROW， = 8）。在 UBROW 中，PO（中位数（Q1-Q3））从 BL（70 W（37-84））增加到 12 周（77 W（58-109），P = 0.01）和 6M 随访（81 W（51-96），P = 0.01），12 周和 6 个月随访之间没有差异（P = 0.21）。同样，V̇O 从 BL（15.4 ml/kg/min（10.5-19.4））增加到 12 周（16.6 ml/kg/min（12.8-21.3），P = 0.01），12 周和 6 个月随访之间没有差异（16.3 ml/kg/min（12.9-19.7），P = 0.74）。CON 中 PO（P = 0.22）或 V̇O（P = 0.27）均无随时间变化的差异。传统心血管代谢危险因素或不同 LTPA 强度的分钟数均无变化。我们证明，在完成 12 周的运动干预后，有氧健身水平至少可以维持 6 个月，这支持了周期性运动干预的使用，以提高 SCI 患者的有氧健身水平。临床试验标识符：NCT04390087。
