Design and Construction of a Sports and Rehabilitation Device to Improve Physical Fitness and Lower Limb Performance

Background: High physical readiness is of great importance for armed forces. Lower limbs are of the most important parts of the body of each person. Objectives: The aim of this study was to design and construct a sports and rehabilitation device to improve physical fitness and lower limb performance. Methods: In this applied research, an electronic diagnostic system was designed to evaluate and enhance split performance. The user can set leg displacement, leg workout mode, recording, and repeatability of the states. The system was proposed with two functions including the increased strength of the legs and the rehabilitate of injured lower limbs by moving them. Results: According to the study design, the subject adjusts the angle between the two lower limbs in the device panel. Then, the device arms automatically start to reach the desired angle. Conclusions: In general, using this device, we could measure and improve the range of motion in the two lower limbs.
