This research aims to identify the effectiveness of using sliding disc drills on some physical variables and the level of technical performance of Tkachev's skill on horizontal bar apparatus in gymnastics. The experimental approach was used using the experimental design for pre-post measurement of one group to suit the nature of the research. The research sample was chosen Intentionally from the gymnastics team players at Qassim University, and the basic research sample included (10) players, while the exploratory study was conducted on a sample of players representing the original community. From outside the main research sample, their number was (10) players who were chosen randomly with the aim of selecting the appropriate sliding disc drills and codifying their training loads. The percentage of improvement in grip strength was (16,50%), The percentage of improvement of legs muscular strength was (16.20%), the percentage of improvement of the back muscular strength was (30.80%), the percentage of improvement of the abdominal muscular endurance was (24.20%), and the percentage of the improvement of the flexibility of the hip joint was (44.20%). The percentage of improvement in the dynamic balance was (32.40%), while the percentage of improvement in the skill (TKATSHEV Piked) was (52.1%), and the percentage of improvement in the skill (TKATSHEV Stretched) was (29.7%), and the percentage of improvement in the skill (TKATSHEV Tucked) was (49.9%). The researcher recommends the use of sliding disc drills to develop physical fitness and the level of technical performance of Tkachev's skill on Horizontal Bar .
