![]() IMUs are integrated with sports training equipment because they are small and collect multiple types of data, including acceleration, orientation in time and space, and direction. What Is an Inertial Measurement Unit?Īn IMU is typically a combination of sensors that assist in collecting the motion of a body or sporting implement, such as a ball. In this guide, we provide a serious look at IMU technology and applications, and review example options that are excellent for sports training and rehabilitation providers. ![]() Simple accelerometers can be found in sleep trackers and even in the smartphones we use every day, and while they are acceptable tools for estimating athlete motion, they are far from perfect. ![]() IMUs are only as useful as the methodology of the users and the algorithms developed by the companies that provide sport systems. Inertial motion units, or IMUs, are sensors that collect motion data that can be used in calculating estimates of work, speed, and even movement angles. The velocity-based training market is now saturated with low-cost sensors and, due to the availability of the technology, the sensors are usually included in body tracking products such as GPS systems and similar wearable technologies. ![]() Unfortunately, due to the low cost of the sensors, the market has been overrun by gadgets instead of precision instruments. The microsensor market, specifically motion sensors found in many devices in sports tracking, exploded over the past few years.
