Experiment research of visual performance feedback of different relative frequency to motor skill learning

Research into augmented feedback in motor skill control and learning was an important subject at home and abroad.Moreover,performance feedback was a more important key problem.Motor skill learners of forehand backspin service were exerted 100% and 30% relative frequency visual mode performance feedback by means of literature study,experiment method and mathematic statistics.The results showed that during the process of motor skill learning,the performance of high frequency visual feedback was better than low frequency visual feedback;during the 3mins retention of motor learning,the performance of high frequency visual feed back was better than low frequency visual feedback;during the 48 hours retention of motor learning,there was no significant deference between the performance of high frequency visual feedback and the performance of low frequency visual feedback.
