[Purpose] The acquisition of motor skills are fundamental to human life. There is a lack
of research on whether knowledge of performance or knowledge of result as augmented
feedback is more effective. The objective of this study was to compare the effectiveness
of knowledge of result and knowledge of performance in the learning of a skilled motor
activity by healthy young adults. [Subjects and Methods] A total of thirty healthy young
adult males and females without any neurological or musculoskeletal impairment, between
the age of 18–30 years were the subjects of the study. They were randomly allocated to 2
groups: group 1 was given knowledge of result as feedback, and knowledge of performance
was given as feedback to group 2. Both the groups practiced the task of throwing a soft
spongy ball for 6 days per week for 4 weeks, with 40 trials each day. The outcome measure
used was the distance of the throw. [Results] The results were analyzed using the t-test.
The mean distances thrown by both the groups showed highly significant improvements and
throwing distance of group 2 showed better improvement than that of group 1. [Conclusion]
Both types of augmented feedback were effective at improving skilled motor activity, but
the knowledge of performance group showed better improvement than the knowledge of result
group.
