    Javelin throwing is a complicated activities and a javelin thrower makes complex multi joint movements that require muscular strength, sophisticated coordination and accurate control. These movements must develop the great force that is necessary to accelerate the javelin to great release speed, while carefully controlling the direction of the release. The generation of great force exerts significance musculoskeletal stress on multiple joint on the upper extremity. These stresses are likely cause of overuse and acute injuries that sustained by javelin throwers. The overall purpose of this study is to investigate the relationship between javelin throwing technique and upper extremity injuries that sustained by javelin throwers in some selected clubs of Ethiopia like defense, prison police, ELPA and commercial bank athletics clubs from Adiss Ababa and sidama buna, south police athletics clubs from SNNP region and Athlete Trunesh Dibaba Athletics Training Center. For this study the entire population of 40 (22 Male and 18 female) javelin throwers were involved. The method of data collection employed includes self structures questionnaire, interview and observation. Data were was collected both from primary and secondary sources. The quantitative data was analyzed by using simple descriptive method such as percentage and the qualitative data was analyzed through interpretation and conceptual generalization. It was identified that release and recovery phases of javelin throwing technique have significant relationship with the injuries that were javelin throwers sustained. Incorrect technique, early specialization, overuse of muscles, unbalance movement of motion and inadequate warming up are the major Causative factors.
