The purpose of this paper was to design a model of key success factors in Taekwondo sport with emphasis on the dimensions of continuous support. The research method was a combination of quantitative and qualitative methods that according to the qualitative method of data collection in the first stage; And its validation in the next stage was of the exploratory mixed type. The statistical population of the study was all executive and academic level experts. The sampling method in the qualitative part was initially purposeful and judgmental and then in order to collect information, the snowball sampling method was used. In this study, theoretical saturation was achieved by interviewing 21 of the samples. The data collection tool was in the first stage of the interview and after coding and identifying the themes and indicators, a questionnaire was developed and used to design and validate the model. Data analysis was performed qualitatively using thematic analysis and quantitatively using Demetel technique. The results of content analysis showed that the key factors of success in Taekwondo sport with emphasis on the dimensions of continuous support include four sections: implementation of support programs, grounding in education, supply of hardware, optimization Is nutrition. The results of Demetel analysis showed the appropriate fit of the research model. Also, the quantitative results of the research showed that the identified factors from the perspective of experts for the development of Taekwondo are in a favorable condition. According to the research results, emphasis on continuous support for the development.

This research is quasi-experimental and applied and was randomly divided into three groups: aerobics, yoga and control. Subjects in the experimental groups participated in a specific exercise program for 8 weeks, 3 sessions per week and each session for 1 hour. Exercises in the aerobic group included 10 minutes of warm-up, 40 minutes of rhythmic movements and 10 minutes of returning to the original state. Aerobic exercises were performed in the first sessions with an intensity of 55% of maximal reserve heart rate and in the last sessions with an intensity of 75% of maximal reserve heart rate. The exercises in the yoga group included 40 minutes of asana exercises, 10 minutes of Shavasana exercises and 10 minutes of pranayama exercises. The control group did not perform any regular exercise and physical activity during the study and only participated in pre-test and post-test at the beginning and end of the training period. In terms of factors affecting the research variables, such as menstrual cycle regularity, lack of specific diseases not taking drugs, smoking, etc., the subjects had similar and similar conditions. Measurement variables in pre-test and post-test were: body composition aerobic power, blood pressure, heart rate, pulmonary parameters, anaerobic power Leg muscles are flexibility and hand strength. Descriptive and inferential statistics were used to analyze the data.
