    摘要： A training aid for use by a player with a tennis racquet includes at least one wing having a proximal end in the throat of the racquet, and extending from that proximal end and tapering down into a distal end. A second wing may also be included, with the two wings extending in opposite directions from the throat of the racquet. When the player makes a stroke with the racquet with the aid attached, air pressure on the wings creates forces which provide the player with feedback on the position of the racquet head during the stroke. The training aid may be removably attached to the racquet, to allow the racquet to be used in normal play situations. A rotatable flap may also be provided near the distal end of at least one of the wings, so that when the flap is rotated the air pressure on the flap during a stroke is altered, thereby changing the feedback provided to the player.

    摘要翻译： 由具有网球拍的玩家使用的训练辅助装置包括至少一个翼，其具有球拍喉部中的近端，并且从该近端延伸并向下渐缩成远端。 也可以包括第二翼，两个翼从球拍的喉咙向相反方向延伸。 当玩家用附带的辅助球拍进行中风时，翼上的空气压力产生力量，其为玩家在中风期间对球拍头的位置提供反馈。 训练辅助装置可以可移除地附接到球拍上，以允许球拍在正常的播放环境中使用。 也可以在至少一个翼部的远端附近设置可旋转的翼片，使得当翼片旋转时，中风期间的翼片上的空气压力被改变，从而改变提供给玩家的反馈。
