The study is meant to find the most effective indicators of technical training improvement of the performance fencers based on biomechanical criteria. A case study was conducted for this purpose, involving teachers and coaches of fencing. The research was based on the survey method, using Google forms questionnaire, consisting of 12 questions and sent on-line. The sociological survey was attended by 10 specialists. The results of the survey highlight: the weight of training factors in different periods of performance fencing preparation; duration of the fencing training sessions; number of training sessions per week carried out in different training periods; structure and weight of fencing training in terms of general physical training, special physical training, technical-tactical training, relationship between work with the coach, work with a partner and free assault; approach of individual lesson model in different periods of personalized training determined by the physical and technical training of the athlete and the pattern of the coach; importance of the biomechanical parameters in the movement phasic structure during the simple and compound actions execution (valid touch); importance of the biomechanical criteria in the technical training of the performance fencers. The opinions of the specialists can contribute to the improvement of the fencing actions by ameliorating the indicators based on biomechanical criteria. The development of algorithmic diagrams can lead to a better technical training of the performance fencers.
