“Pain syndrome of musculoskeletal system appearing during physical exercise without any known trauma, disease, deformity or abnormality that might have given previous symptom. The symptoms started during physical exercise and were located as a previously symptom-free region of the body. Temporary muscle pains associated with increasing training were not recorded in the study. The diagnosis of an overuse injury was made on the basis of medical history and a thorough medical examination. “
