Abstract

The purpose of the present study was to investigate the changes in kinematic, and dynamic characteristics and also the accuracy of the service of forehand clear service, after the combined use of observational learning and verbal feedback during the skill acquisition. Twenty-one amateur badminton athletes participated in the study (age 11.4 ± 0.3 years, body mass: 46±0,2 kg and height 155 ±2.75 cm). They were separated in three groups comparable to number of participants and accuracy performance of service: Learning of Observation group with verbal instructions (L.O.G.), Verbal Feedback group (V.F.G.) and control group (C.G.).
For the evaluation of accuracy the “ French forehand clear service Test ” (1941) was used. The athletes followed an 8-week program with 45 minutes sessions twice per week. Fifteen points in the kinetic system were studied. Variables related to displacement, velocity, vertical max force and the accuracy was evaluated. The results showed that for some variables there were statistically significant differences between the experimental groups and the control group for the factor time and for the group factor. The L.O.G. group presented changes in the kinematic characteristics of the forehand clear service in the linear displacement of raquet in
the (y) axis in third phase of movement (DRAKy3), as well as in the linear speed of the raquet (BRAKZ 2) in the vertical axis (z) in the second phase of movement, while it also showed improvement in the accuracy of the particular service.
