The focus of this study was to develop a force measurement device capable of tracking forces, moments, and the center of pressure throughout a sprint start. Both of the beginning blocks' force plates are independently adjustable, and they have a pair of force sensors (Loadcell Type- SQB/SQB-A/-SS/-ASS). Currently, commercially available expensive block start force plate use to measure the force production of the block clearance. The two-cantilever type loadcells used to produce this equipment can measure a maximum of 2500N depending on the use of the equipment. Start Blocks incorporate a charging amplifier. The system's sensor component is paired with a signal processing subsystem. To process the signal using the Cool term software and using the Mega 2560 is a microcontroller board with two HX711 Amplifier Module connect to the pressure sensors. Get data output using (Python with C or C++) of Graphical Programming Language (Cool Term Calibration Process and Visualize Data from Sensors Using Arduino + Cool term) Programming. The method utilizes an HC-SR94 ultrasonic sensor and an Arduino Uno chip. Finally, all the cool term columns data can get from the Excel sheet as a Graphical Data. In this study starting bock clearance force production is not statistically significant (P > 0.05). It indicates that the force production performs at a somewhat lower level than the female side in terms of performance. Therefore, possible to identify the athlete force production effect to the Block clearance peak performance. This Force Plate is easy for coaches and athletes to identify force production effectiveness for athlete's block starts performances.
