Abstract: Training at the proper level of effort is important for athletes whose objective is to achieve the best results in the least time. In running, for example, pace is often monitored. However, pace alone does not reveal specific issues with regard to running form, efficiency, or technique, much less inform how training should be modified to improve performance or fitness. A sensing system and wearable sensor platform described herein provide real-time feedback to a user/wearer of his power expenditure during an activity. In one example, the system includes an inertial measurement unit (IMU) for acquiring multi-axis motion data at a first sampling rate, and an orientation sensor to acquire orientation data at a second sampling rate that is varied based on the multi-axis motion data.

Abstract: The technology relates to a measurement system that is retained by an athlete during an athletic activity. In an example, the measurement system includes a housing that includes: an accelerometer; a gyroscope; at least one processor; and at least one memory, the at least one memory storing instructions that, when executed by the at least one processor cause the system to perform operations. In an example, the operations include receiving accelerometer data and gyroscope data generated by the accelerometer and the gyroscope during a ground-contact portion of a stride; generating one or more impact metrics based on at least one of the accelerometer data or the gyroscope data; generating a real-time pacing value based on the generated one or more impact metrics; and causing a physical output based on the generated real-time pacing value.

Abstract: Systems and methods for determining the impact of air resistance on the power being produced by a body motion are disclosed. In one aspect, a method includes measuring positions and orientations of a portion of the body in motion. The method further includes measuring pressure experienced by the portion of the body in motion. The motion further includes calculating a static pressure based on the measured pressures and correlated position and orientation measurements. The method further includes calculating a maximum pressure and calculating an air induced power exerted on the body in motion.
