The aim of research work: to evaluate low back pain, history of injury, functional status and the relationship between the results in male kickboxers. Tasks of work: 1. To evaluate most common injuries in male kickboxers. 2. To evaluate low back pain prevalence in male kickboxers. 3. To evaluate functional status in male kickoxers: posture, flexibility, endurance of lumbar muscles, shortened hip muscles, balance and lumbar stability. 4. To assess the relationship between low back pain, history of injury and funcional status in male kickboxers. Materials and methods: The research was conducted in the period of 2016 December – 2017 May at the martial arts club “Rings“ in Vilnius. 20 kickboxers, with an average age 26,7±6,3, have been examined individually. The history of injury and low back pain was examined in the questionnaire. Funcional status was examined in physical examination tests. Posture type was evaluated with vertical line on the sagittal plane. Lumbar flexibility was evaluated in “Sit and reach“ and side bending to the right and to the left tests. Static endurance of lumbar muscles was assessed by McGill method. Shortened hip muscles was assessed by classic and modified Thomas tests and straight leg raising test. Dynamic balance was measured by Modified Star Excursion Balance Test (MSEBT). For lumbar stability testing stabilizer was used. Data analysis was conducted using „IBM SPSS Statistics 25.0“ and Microsoft Excel 2008 software. Results: 85% of the participants experienced at least one injury in sport, most common were upper extremity injuries – 62,5% and lower extremity injuries – 36,4%. 80% of participants experienced at least one episode of low back pain (LBP), 62,5% affected by chronic LBP. 85% of kickboxers had poor posture, 45% had rectus femoris muscle shortening. Statistical analysis showed statistically significant correlations (p
