To test the hypothesis that hybrid functional electrical stimulation (FES) row training would improve aerobic capacity but that it would remain strongly linked to level of spinal cord lesion because of limited maximal ventilation.
Longitudinal before-after trial of 6 months of FES row training.
Exercise for persons with disabilities program in a hospitaL.
Volunteers (N=14; age range, 21-63y) with complete spinal cord injury (SCI) (T3-11) who are >2 years postinjury.
Six months of FES row training preceded by a variable period of FES strength training.
Peak aerobic capacity and peak exercise ventilation before and after 6 months of FES row training.
FES row training significantly increased peak aerobic capacity and peak minute ventilation (both P<.05). Prior to FES row training, there was a close relation between level of SCI and peak aerobic capacity (adjusted R(2)=.40, P=.009) that was markedly reduced after FES row training (adjusted R(2)=.15, P=.10). In contrast, the relation between level of injury and peak minute ventilation was comparable before and after FES row training (adjusted R(2)=.38 vs .32, both P<.05).
The increased aerobic capacity reflects more than increased ventilation; FES row training effectively circumvents the effect of SCI on peak aerobic capacity by engaging more muscle mass for training, independent of the level of injury.
验证以下假设，即混合功能性电刺激（FES）划船训练可提高有氧能力，但由于最大通气量有限，其仍与脊髓损伤水平密切相关。
对FES划船训练6个月进行纵向前后对照试验。
医院的残疾人运动项目。
损伤2年以上、脊髓完全损伤（SCI）（T3 - 11）的志愿者（N = 14；年龄范围21 - 63岁）。
在进行6个月的FES划船训练之前，先进行一段可变时长的FES力量训练。
FES划船训练6个月前后的峰值有氧能力和峰值运动通气量。
FES划船训练显著提高了峰值有氧能力和峰值分钟通气量（P均<0.05）。在FES划船训练前，SCI水平与峰值有氧能力之间存在密切关系（调整后R² = 0.40，P = 0.009），而在FES划船训练后这种关系明显减弱（调整后R² = 0.15，P = 0.10）。相比之下，损伤水平与峰值分钟通气量之间的关系在FES划船训练前后相当（调整后R²分别为0.38和0.32，P均<0.05）。
有氧能力的提高不仅仅反映在通气量增加上；FES划船训练通过让更多肌肉参与训练，有效地规避了SCI对峰值有氧能力的影响，且不受损伤水平的影响。
