Overtraining has become a major problem in college sports today and there is an increasing need for devices to track or measure the amount of stress is being put on the bodies of athletes. One such device is the ZephyrTM BioHarness, which is a puck-like device worn on the chest and is the centerpiece of this study. Researchers wanted to answer the question of whether the ZephyrTM was an effective and valid tool to measure the amount of force placed on the body during a single vertical jump. There were 20 male participants used in this study, 10 Division I college basketball athletes and 10 recreational athletes of college age. Participants were put through a standard vertical jump test while wearing the ZephyrTM on their chest and landing on a force plate. This allowed researchers to compare the data of the force plate and the ZephyrTM. After data collection and analysis, it was determined that the ZephyrTM was effective for the Division I athletes for the average force of the vertical jump. All other combinations of data showed that the ZephyrTM was not an effective or tool.
