A self-powered vibration mechanism is provided that can be mounted on an existing pedal shaft yet operates independent from the existing pedal. Mechanical isolation or mechanical decoupling permits transferring the vibrating energy to the foot rather than to the pedal shaft and the bicycle. In another embodiment, a full removable pedal with self-powered vibration mechanism can replace an existing pedal.

Improved assessment of brain injuries, and improved brain injury management, is achieved using a combination of impact-related data derived from instrumented mouthguard devices, human function performance testing, and biomarkers derived from biological fluid (such as saliva and/or blood). The human function performance testing may include brain function performance testing, and/or other forms of human function performance testing. This involves combining a data-driven understanding of a head impact event (based on data collected via an instrumented mouthguard device) with a data-driven understanding of human function performance following that head impact event. The biomarkers may include salivary mRNA and/or ncRNA, and/or blood proteins (for example via a FDA-approved Brain Trauma Indicator test).

Embodiments of footwear to optimize propulsion while swimming in the water and walking on land, in particular, amphibious footwear capable of duty on land and in the water as well as versions that are optimized for predominantly use in the water for swimming. The exoskeleton amphibious footwear reduces metabolic demand of walking and swimming while also improving gait speed and swim speed. This is accomplished by assisting plantar flexion during land mode, and assisting dorsiflexion in water mode.

A system and a method for recommending a physical routine to a person. The system includes a physical sensor, a biochemical sensor and a processing arrangement. The processing arrangement is configured to measure, via the physical sensor, a first intensity and a corresponding first training impulse of a first physical routine, and a second intensity and a corresponding second training impulse of a second physical routine; determine, via the biochemical sensor, a first level of a biochemical marker associated with completion of the first physical routine and a second level of a biochemical marker associated with completion of the second physical routine; calculate a corresponding first response value and a second response value; compare the calculated first response value and the calculated second response value, and recommend one of the first physical routine and the second physical routine for the person based on the comparison.

Tracking and monitoring athletic activity offers individuals with additional motivation to continue such behavior. An individual may track his or her athletic activity by completing goals. These goals may be represented by real-world objects such as food items, landmarks, buildings, statues, other physical structures, toys and the like. Each object may correspond to an athletic activity goal and require an amount of athletic activity to complete the goal. For example, a donut goal object may correspond to an athletic activity goal of burning 350 calories. The user may progress from goal object to goal object. Goal objects may increase in difficulty (e.g., amount of athletic activity required) and might only be available for selection upon completing an immediately previous goal object, a number of goal objects, an amount of athletic activity and the like.

A treadmill includes a frame, an exercise deck attached to the frame, and a first handle movably attached to the frame. The first handle has a first orientation where the first handle is positioned within a region above the exercise deck and stabilized to support a user's weight during a body weight exercise, and a second orientation where the first handle is positioned away from the region above the exercise deck.

A portable smart hand grip according to an embodiment of the present disclosure includes a first housing, a guide part combined with the first housing and including a first receiving portion and a second receiving portion, a second housing facing the first housing and having a first pressing portion and a second pressing portion which are received in the first receiving portion and the second receiving portion, respectively, a first elastic member disposed between the first pressing portion and the first housing, a second elastic member disposed between the second pressing portion and the first housing, a sensor received in the first housing for detecting a user's operation of the portable smart hand grip, a control circuit unit received in the first housing to control an operation of the sensor, and a battery unit received in the first housing to provide power to the control circuit unit.

A treadmill with a safety warning function includes a miming unit, a driving unit, a detection unit and a control unit. The running unit includes a driving roller and a running belt provided for a runner to stand thereon. The detection unit includes a camera arranged at a predefined height range on top of the running belt for photographing images. The control unit determines a height of the runner based on the images photographed. The safety monitoring method for the treadmill includes obtaining an image above the running belt and determining whether the height of the runner is greater than the predefined height. By determining whether the height of the runner is greater than the predefined height, it is able to determine whether the driving roller can be driven by the driving unit to rotate, thereby preventing the hazard of accidental activation by a child of insufficient height.

A dry swim simulation system is described. A portion of the system includes a platform extending vertically from the base platform and a first and a second retractable pulley. Another portion of the system includes a first support assembly comprising a first movable cradle configured to receive thighs of the user and a second support assembly. The second support assembly includes a second movable cradle configured to receive a torso of the user, a computing device, and a headrest comprising an opening configured to receive a face of the user such that the user views the computing device. The computing device is configured to receive parameters associated with the user during use of the dry swim simulation system from numerous electrical and/or mechanical components. The computing device is configured to analyze the parameters and provide real-time feedback to the user to improve performance of swimming strokes.
