This research aims to identify the effect of Tabata protocol workouts on some physical and Physiological variables and the level of technical performance of Thomas flair on pommel horse apparatus in gymnastics. The researcher used 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 Tabata protocol workouts and codifying it's training loads. the most important results were as follows: The percentage of improvement for the physical variables ranged between (11.7%, 52.1%), and the highest percentage of improvement was for the (legs muscular power) by (52.1%), and the lowest percentage of improvement was for (back muscles strength) by (11 ,7%), and the percentage of improvement of the rest elements ranged between them, while the percentage of improvement of physiological variables ranged between (2.9%, 37.1%), and the highest percentage of improvement was for the anaerobic ability variable by (37.1%), and the lowest percentage of improvement was for the rest pulse rate by (2.9%). While the percentage of improvement for the technical variable (Thomas Flair) by (34.6%).Researcher recommends using Tabata workouts to develop the level of technical performance of Thomas Flair's skill on the pommel horse.
