Intro to Force Plates and Performance Testing Software
This course is an introduction to force plates and performance testing. This course covers the basics of setup and calibration of force plates, and then walks through several fundamental performance tests including squat jumps, countermovement jumps, drop jumps and loaded jumps. Two versions of the isometric mid-thigh pull as well as an isometric squat are also covered in the course. Real-time data collection from the software is also shown as the athletes are performing the tests. A module on data analysis rounds out the course, which includes five metrics collected from the force plate, as well as calculations from this data, including relative strength index - modified, and dynamic strength index.
