A myodynamic measurement system is provided in the present invention. The myodynamic measurement system comprises a myodynamic measurement device and a controller. The myodynamic measurement device comprises a main body, a motor, a clutch, a rope, a handle, an accelerometer, and a displacement detector. The main body has an allocation space and a through hole. The motor is disposed in the allocation space. The clutch is disposed in the allocation space and engaged with the motor. The rope is engaged with the clutch and is extended from the through hole. The handle is fixed on the rope. The accelerometer is utilized for detecting acceleration change of the handle. The displacement detector is utilized for detecting a moving distance of the rope. The controller comprises a communication module and a control module. The control module is utilized for controlling the motor to provide a pulling force and controlling the clutch to engage with the motor and the rope through the communication module.

The present invention provides a competitive weightlifting system capable of interacting with and comparing weightlifting performances of multiple users, and creating competition between such users by displaying a ranked list of performances by those users. The system may include a frame for supporting and guiding a lift bar, sensors mounted to the frame for measuring and refereeing the performance of a user, a controller housed in the frame for tracking and ranking user performances with an interface for creating and logging into user profiles, and a communication device for sharing user performance data with other remote competitive weightlifting systems (e.g., competitive weightlifting systems in other gyms or homes) in order to create a wide-ranging competition between, and ranked leaderboard of, the many users.
