The purpose of this study was to investigate the effectiveness of a sensorimotor rhythm (SMR) neurofeedback training (NFT) and biofeedback training (BFT) intervention on ice hockey shooting performance. Specifically, the purpose was to examine (a) whether an NFT/BFT program could improve ice hockey shooting performance, (b) whether the implementation of an SMR-NFT intervention leads to neurological adaptations during performance, and (c) whether such neurological changes account for improvement in shooting performance. Using a longitudinal stratified random control design, results demonstrated that while both SMR-NFT/BFT and control groups improved performance, the rate of improvement for the SMR-NFT/BFT group was significantly higher than the control. Participants in the SMR-NFT/BFT group demonstrated the ability to significantly increase SMR power from pre- to postintervention in the lab. However, no significant changes in SMR power were found during shooting performance. This result may be suggestive of differing cortical activity present during motor-skill preparation.

综合神经反馈和生物反馈训练干预对冰球射击表现的影响。

本研究的目的是调查感觉运动节律（SMR）神经反馈训练（NFT）和生物反馈训练（BFT）干预对冰球投篮表现的有效性。具体来说，目的是检查（a）NFT/BFT 计划是否可以提高冰球射击表现，（b）实施 SMR-NFT 干预是否会导致表现期间的神经适应，以及（c）这种神经变化是否考虑到拍摄性能的提高。使用纵向分层随机对照设计，结果表明，虽然 SMR-NFT/BFT 和对照组的表现均有所改善，但 SMR-NFT/BFT 组的改善率显着高于对照组。SMR-NFT/BFT 组的参与者在实验室中展示了从干预前到干预后显着提高 SMR 功效的能力。然而，在射击表演过程中，没有发现SMR威力发生明显变化。这一结果可能表明运动技能准备过程中存在不同的皮质活动。
