Effects of variability of practice using the concept of differential approach and traditional learning on learning round-off in gymnastics based on the analysis of movement construction

: The objective of this study is to assess the effect of differential learning approach in comparison with the traditional learning in learning round off in gymnastics as a one of close motor skill. thirty two accademic students (boys M = 20.5, SD = 3.2 years) parallelized to two groups according to pre-test results: differential learning group wheareas the other group was tranditional learning group. in both groups 90. Min. Training units (2 dayes/week) were performed for 8 weeks. The 'Differential learning' group was based on the indications for differential learning according to Schöllhorn (1999), tabel (1) shows a list of possible variations of the round off. In this experiment differential learning group completed stochastic movement variations and Increasing the number of movement fluctuations, The 'tranditional learning' group completes a methodical series of round off with blocks of repetitive movements that build on one to another, in addition the students in this group was perfromed the skill with corrective feedbacks. The contents of traditional technique training are based on the classic methodical exercise series for learning the round off. Results was determined that, differential learnig method is more effective than traditional learning method in learing round off in gymnastics.
