This is an open randomized controlled trial.
The objective of this study was to investigate the effects of a 16-week hybrid cycle versus handcycle exercise program on fitness and physical activity in inactive people with long-term spinal cord injury (SCI).
The study was conducted in two rehabilitation centers with a specialized SCI unit.
Twenty individuals (SCI⩾8 years) were randomly assigned to a hybrid cycle (voluntary arm exercise combined with functional electrical stimulation (FES)-induced leg exercise) or a handcycle group. During 16 weeks, both groups trained twice a week for 30 min at 65-75% heart rate reserve. Outcome measures obtained before, during and after the program were fitness (peak power output, peak oxygen consumption), submaximal VO2 and heart rate (HR), resting HR, wheelchair skill performance time score) and physical activity (distance travelled in wheelchair and Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) score). Changes were examined using a two-factor mixed-measures analysis of variance.
For all fitness parameters, except for submaximal VO2, no interaction effects were found. The hybrid cycle group showed a decrease in VO2 over time in contrast to the handcycle group (P=0.045). An overall reduction in HRrest (5±2 b.p.m.; P=0.03) and overall increase in PASIPD score (6.5±2.1; P=0.002) were found after 16 weeks of training. No overall training effects were found for the other fitness and activity outcome measures.
In the current study, hybrid cycling and handcycling showed similar effects on fitness and physical activity, indicating that there seem to be no additional benefits of the FES-induced leg exercise over handcycle training alone.

本研究的目的是调查16周混合周期运动与手摇自行车运动方案对长期脊髓损伤（SCI）的非运动人群的体能和身体活动的影响。
研究在两个设有专门脊髓损伤治疗单元的康复中心进行。
20名个体（脊髓损伤⩾8年）被随机分配至混合周期运动组（自主手臂运动结合功能性电刺激（FES）诱发的腿部运动）或手摇自行车组。在16周内，两组均每周训练两次，每次30分钟，心率储备保持在65 - 75%。在运动方案实施前、期间和之后获取的结果指标包括体能（峰值功率输出、峰值耗氧量）、次最大摄氧量和心率（HR）、静息心率、轮椅技能表现时间得分）以及身体活动（轮椅行驶距离和残疾个体身体活动量表（PASIPD）得分）。使用双因素混合测量方差分析来检验变化情况。
对于所有体能参数，除了次最大摄氧量外，未发现交互作用效应。与手摇自行车组相比，混合周期运动组的摄氧量随时间下降（P = 0.045）。经过16周训练后，发现静息心率总体降低（5±2次/分钟；P = 0.03），PASIPD得分总体增加（6.5±2.1；P = 0.002）。对于其他体能和活动结果指标，未发现总体训练效果。
在当前研究中，混合周期运动和手摇自行车运动在体能和身体活动方面显示出相似的效果，这表明FES诱发的腿部运动相较于单纯的手摇自行车训练似乎没有额外益处。
