Aims: Monitoring is a new method that allows coaches and physical trainers to manage training in order to meet the needs of athletes. This study aims to evaluate through a scientific approach the homogeneity between the training program established by the coach in the pre-competition period, and the characteristics of the competition. Materials : The study was conducted at the FAR (Royal Armed Forces) Sports Association in Salé from February 10, 2019 to March 16, 2019, on a sample of 12 taekwondo athletes (5 girls and 7 boys), category "senior" with a middle age of 26.28 ± 1.97 for boys and 24.4 ± 3.32 for girls. The data collection concerns two different periods, the training and the competition period, in order to make a comparison between the different phases of the combat situations (preparation phase, exchange phase and recovery phase) during these two periods: Results: For the combat in the training period we saw that the percentage of the preparation phase was 80.11%, the exchange phase was 19.69%, and the recovery phase was 0.18%, however, in the competition period, the percentage of the preparation phase is 21.60%, the exchange phase is 39.84%, and the recovery phase is 38.54%. The study of the correlation between the three phases of combat in the training period and the competition shows that there is no link between the different phases except between the exchange phase and the recovery phase (sig = 0.021 < 0.05). Conclusion: Our study was able to reveal that the requirements of the competition were not taken into consideration by the coach, which influenced the performance of the athletes during the competition. Therefore, a monitoring program is necessary in order to better plan the training and even predict the results of the competition
