The purpose of research is to evaluate the ergonomics of sports equipment located in parks and public spaces in Tehran. For this purpose, 4 areas of Tehran municipality were selected as study sites and 2 parks and 2 recreation areas were selected from each. Three devices were evaluated. REBA technique was used for posture assessment and William Fine method was used for risk assessment.Three devices were evaluated. The REBA technique was used to assess posture and the William fine method was used to assess risk. The PMBOK, 2000 model was also used to provide risk reduction solutions. The results of the posture evaluation show that working with the Rotary ship rudder has a very high risk (the risk number is higher than 13). After that, the device "leg and underarm Press" has a high risk level (risk number 9). Finally, the "elliptical" device has an average risk level (risk number 6). rank and risk level of the sports equipment studied were evaluated based on 2 separate methods. results indicate that in both evaluation methods, the lowest level of risk assessed belonged to the elliptical device. But the results of the methods used differ between the highest risk levels assessed for the sports devices studied. So in the posture assessment method (REBA),ship's Rudder had the highest degree of risk, while according to the William fine assessment method, the leg and underarm Press showed the highest level of risk. General solutions for risk management include: aggressive, defensive, conservative and combined solutions.
