© 2021 Elsevier Masson SASAim: Musculoskeletal pains are often due to the ergonomics risk factors of the environment. Furthermore, as the routine sport training involving aerobic exercises provides a fit and adequate musculoskeletal structure, doesn't affect the core stabilization muscles. Therefore, strengthless muscles and unstable lumbo-pelvik musculoskeletal system provoke pain in related anatomical region. In this context, we aimed to evaluate the statistical relationship between the ergonomic approach and lack of core stabilization exercises with musculoskeletal pains of athletes. Material and methods: A total of 80 athletes participated in our work. Standardized ergonomic muscle and skeletal system pains questionnaires were applied to participants. Correlation tests were performed and statistically evaluated by comparing the parameters such as gender, age range, height, weight, and sports age period. Also 52,25% (n: 41) of athletes complain of lumbar pain. Core stabilization exercises were performed during six weeks. Initial VAS and final VAS were analyzed. Results: In total, 88,75% (n = 71) of participants had complaints of pain related to musculoskeletal system during the last week. Age, height, weight, and age of sport showed significant correlations with pain complaints seen in some body regions as topographically (P < 0.05). Also, a significant decrease of pain was observed after six weeks. Ergonomic conditions, incorrect static posture and core stability may be influential factors in the formation of musculoskeletal system diseases. The ergonomic change needs to involve both sports methods and working environments. Also, including core stabilization exercise in routine training program may ensure a pain decrease and an increase in performance.
