Background and Study Aim: The role of body posture is often underestimated in a sport performance. The sport training often focuses only on achieving the highest level of performance. On the other hand, this type of condition can be connected with serious health problems which can be one of the reasons of career-ending injury. One of them, which can often occur during the athletes training are low and upper back pain. Back pain syndromes are often completely preventable. The highest level of postural control and postural stability is required in sport when the athletes have to maintain the position in static or dynamic position during single-leg stance. The main aim of the study was the answer to question: whether is a significance difference between value of cervical lordosis and lumbar lordosis value during 2 years of study in Special Education of Security Sections (in pre-test and post-test)? The question is how the trainer can integrate the training with corrective exercises?
Material and Methods: Nineteen healthy students participated in this study (mean age = 20.2 ±1.32 years; mean height = 1.80 ±0.05 m; mean mass = 76.93 ±7.90 kg). The participants practiced combat sports in average 5.8 ±2.52 years. Before study, participants responded questions about personal information (age, sex, combat sport, length of sport practice and regeneration in their sport practise). DTP-3 diagnostic system was used for measuring body posture. The examination includes palpating and marking chosen points (the skin projection of the left and right lateral parts of the acromion, bilateral posterior superior iliac spine and 22 processus spinosi C3–L5. The chosen points were measured by touching the stylus of the sensor and then transmitted into the computer. The participant´s free standing position was measured 3 times in pre-test and post-test.
Results: The results showed that field of study Special Education of Security Sections had positive impact of value cervical and lumbar lordosis in a group of students (cervical lordosis: pre-test 3.57 ±0.99; post-test 2.84 ±0.89 and lumbar lordosis: pre-test 4.82 ±0.73; post-test 3.89 ±0.89). The paired samples t-test was used for cervical lordosis value and lumbar lordosis value (p = 0.000001; p = 0.000065; the significance level 95%). 
Conclusions: According to the results, the field of study Special Education of Security Sections at Faculty of Sports Study improved the value of cervical lordosis and lumbar lordosis and it was also observed a shift from asymmetry between shoulders position. The design of the field of study includes also corrective exercises and theoretical lectures about importance of body posture and postural stability.
