运动启动，配对高强度的运动与运动学习任务，提高保留上肢任务的个人中风后，但没有表现出任何好处的运动学习。这种差异可能与所研究的学习类型有关。上肢研究使用明确的，战略性的任务;运动研究使用内隐感觉运动适应（分裂带跑步机）。由于步行是一个重要的康复目标，这是至关重要的，以了解在何种情况下，运动启动可能会提高保持一个新学习的步行模式。确定运动启动对慢性卒中幸存者外显策略性运动学习任务保持的影响。慢性中风幸存者（>6个月）进行了两次跑步机行走。视觉反馈用于训练增加的步长。参与者被分配到对照组（不运动），连续运动（5分钟高强度）或长间隔运动（15分钟高/中等间隔）。在第一天的学习之后，参与者要么休息，要么进行锻炼。在第2天，测试学习的行走模式的保持。所有组在第1天学习（p<0.001）。两个预激组在运动预激后血乳酸和心率均有显著变化，而安静对照组无显著变化（P> 0.001）。在第2天，有线索或无线索的任务保持没有显着的组间差异（分别为p=0.963，p=0.287）。运动启动并不影响慢性卒中幸存者外显运动任务的保持。进一步的工作应探讨亚组的个人，他们的启动可能有选择性的临床效益，自发学习。
Exercise priming, pairing high intensity exercise with a motor learning task, improves retention of upper extremity tasks in individuals after stroke, but has shown no benefit to locomotor learning. This difference may relate to the type of learning studied. Upper extremity studies used explicit, strategic tasks; locomotor studies used implicit sensorimotor adaptation (split-belt treadmill). Since walking is an important rehabilitation goal, it is crucial to understand under which circumstances exercise priming may improve retention of a newly learned walking pattern. Determine the impact of exercise priming on explicit, strategic locomotor learning task retention in chronic stroke survivors. Chronic stroke survivors (>6 months) performed two treadmill walking sessions. Visual feedback was used to train increased step length. Participants were assigned to control group (no exercise), continuous exercise (five minutes high intensity), or long-interval exercise (15 minutes high/moderate intervals). After day 1 learning, participants either rested or performed exercise. On day 2, retention of the learned walking pattern was tested. All groups learned on day 1 (p<0.001). The two priming groups showed significant changes in blood lactate and heart rate after exercise priming, the resting control group did not (p<0.001). On day 2, there was no significant between-group difference in cued or un-cued task retention (p=0.963, p=0.287, respectively). Exercise priming did not affect retention of an explicit locomotor task in chronic stroke survivors. Further work should explore subgroups of individuals for whom priming may have selective clinical benefit to locomotor learning.
