Technology facilitates dynamic variability of head impact data recordal, for example, in the context of instrumented mouthguard devices. Some embodiments have been developed to facilitate an event recoding protocol that dynamically adjusts event recoding parameters thereby to provide appropriate data for both “short” and “prolonged” impact events. For example, various embodiments include methods for recording impact events in respect of an instrumented mouthguard device, such methods including dynamically adjusting a period of time for which event data is recorded for a given event responsive to length of time for which an over-threshold condition persists.

A swing motion trainer used to simulate one or more sport swing movements includes a rod portion comprising a shaft with a grip. The swing motion trainer includes a resistance portion comprising an interchangeable mechanism at a distal end of the rod portion, the resistance portion includes an interchangeable mechanism at the distal end of the rod portion, wherein the interchangeable mechanism is configured to attach a removable resistance element to the distal end of the rod portion. The removable resistance element that is attachable to the distal end of the rod portion via the interchangeable mechanism. The removable resistance element provides a resistance to a swinging motion of the swing motion trainer.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A surfing simulation device can be wirelessly connected with virtual reality (VR) glasses. The surfing simulation device includes a surfboard, a surfboard base, and a controller disposed in the surfboard base. The controller controls the actions of the surfboard based on scene information associated with a surfing scene displayed in the VR glasses, such that the actions of the surfboard are synchronous with the surfing scene displayed in the VR glasses. The surfboard of the surfing simulation device can make simulating actions in real time by synchronizing with a surfing scene displayed in VR glasses, such that users can experience the immersive feeling.

Aspects relate to a portable device that may be used to identify a critical intensity and an anaerobic work capacity of an individual. The device may utilize muscle oxygen sensor data, speed data, or power data. The device may utilize data from multiple exercise sessions, or may utilize data from a single exercise session. The device may additionally estimate a critical intensity from a previous race time input from a user.

Systems and methods for prescribing athletic activity to be performed by a user, and for adapting the prescribed athletic activity based on completed (e.g. ongoing) athletic performances by the user. A coaching plan may be automatically created that prescribes personalized athletic activities as a user trains towards a goal date. The athletic information may be received from one or more sensor devices associated with a user, and the coaching plan may be continuously or intermittently updated based on the received sensor data.

A speed control system and method for controlling the speed of an endless belt loop of a treadmill. The speed control system comprises a plurality of image sensors, each image sensor configured to take an image of a user of the treadmill; and a controller configured to control the speed of the endless belt loop by (a) receiving the images of the user taken by the image sensors, (b) rectifying the images based on a calibration of the image sensors, (c) comparing the images to form a disparity map, (d) determining a distance of a user of the treadmill relative to the treadmill using the disparity map, and (e) calculating velocity or acceleration of the treadmill based on the determined distance of the user.

Disclosed are various embodiments of a golf training system. In one non-limiting example, a system includes a feedback device, a sensor, and a computing device. The computing device is configured to at least receive sensor data from the sensor during the golf swing of the user and identify a plurality of body movements in which each respective body movement corresponds to a stage of a golf swing sequence based at least in part on the sensor data.
