Three feedback methods in acquisition and retention of badminton skills.

Comparison of three different feedback methods using information about the correct execution of the technique, errors of execution, and a combination of these on the acquisition and retention of two badminton skills of different difficulty were examined. Participants were 48 young male athletes, 10 to 14 years of age, with 2 to 4 years of training. They were divided into three equal groups and instructed on the long forehand serve, a more difficult serve than the short backhand.
