An exercise treadmill is disclosed. The treadmill can be constructed with no obstructing front rails, with one or more side rails, and/or with a structural flat or ramped surface at the front allowing the user to exercise with unconstrained motion. The treadmill can further include one or more accommodations to help the user stay safe, remain longitudinally centered, and/or adjust speed with controls built into the treadmill, or automatically based on body position relative to sensors built into the side rails. The treadmill belt may be motor driven, or be user driven and dynamically moderated by resistance. The treadmill configuration can be utilized to provide a virtualized exercise experience for the user.

Systems and methods for electronically providing fitness activity feedback to a user are disclosed. The method may include collecting performance data, generating comparison data by comparing the respective performance and including identifying comparison performance data representative of performance differences, and displaying the comparison data and the comparison performance data.

A treadmill includes a frame and a running belt coupled to the frame. The running belt is configured to rotate relative to the frame. The treadmill includes a controller coupled to the frame, and at least one sensor coupled to the controller. The at least one sensor is configured to collect information regarding a rotation of the running belt and a use of the treadmill by a user including a cadence, a ground contact time, and a stride length of the user of the treadmill. The treadmill further includes a display device coupled to the frame. The display device is configured to display the collected information regarding the rotation of the running belt, the cadence, the ground contact time, and the stride length of the user of the treadmill. The at least one light source is configured to selectively emit a light regarding the treadmill.

A motion device for a virtual reality interaction includes a core, a running belt carried by the core and a frame. The running belt is configured to wrap the core and capable of sliding on the outer surface of the core. The running belt includes a number of running belt units. A surface of each running belt unit facing the core is provided with a number of grooves, and each groove of each running belt unit is connected with a corresponding groove of an adjacent running belt unit through an elastic strap. The frame is located at a periphery of the running belt and is configured to carry the running belt and the core. A number of first balls are arranged between the frame and the running belt.

A walking training system includes a treadmill configured to prompt a trainee to walk, a display device installed such that the trainee views the display device while walking on the treadmill, a camera configured to image the trainee at an angle of view at which a gait of the trainee is recognizable, a calculation unit configured to calculate a tilt of a body core of the walking trainee based on an image captured by the camera, and a display control unit configured to control the display device to display a body core line associated with the tilt, and an index indicating at least an end of a permissible range of a deflection of the body core line.

The present invention discloses a running parameters detection system for treadmills and detection method thereof, wherein the system detects the running change data generated by a user running on a treadmill configured with a running belt, a motor and an electronic circuit device by means of a sensor, as well as the running belt operation speed data of the treadmill, in which the running change data is the current data or vertical acceleration data; subsequently, the running change data can be further applied to determine the touchdown moment recording point and the off-ground moment recording point, thereby then, based on such two time points, further calculating various kinematic parameters, e.g., touchdown time, in-the-air time, stride frequency, stride length and vertical amplitude or the like; for example, such five kinematic parameters can be utilized for scientifically monitoring and training runners.

The technology disclosed here involves classifying activity data based on inactivity types. An example method involves receiving, by a processor, activity data of one or more sensors, the activity data comprising a plurality of sensor measurements associated with multiple parameters monitored during an activity session of a user; retrieving a set of criteria that comprises thresholds to detect a plurality of inactivity types, wherein the set comprises a criterion related to a physical activity; classifying, by the processor based on the set of criteria, the received activity data of the one or more sensors into one or more segments, wherein the one or more segments comprise a segment comprising a portion of the activity data corresponding to an inactivity type of the plurality of inactivity types; and generating output based on the classifying.

A treadmill includes a frame. The frame includes a first side member, a second side member, and a cross-member coupled to and extending between the first side member and the second side member. The treadmill also includes a belt coupled to the frame and configured to rotate about the cross-member. The treadmill also includes a light source coupled to the first side member, the second side member, and the cross-member and a controller configured to control the light source.

A treadmill includes a frame. A running belt is coupled to the frame so that the running belt is adapted for rotation relative to the frame. At least one sensor is adapted for collecting parameter information regarding the experience of a user of the treadmill. The parameter information is selected from the group consisting of the user's heart rate, total expended calories, stride length, stride force, cadence, pace, distance, resistance level, incline level, carver count, carver cadence, step count, ground contact time, relative position within a race, and relative position on the treadmill. The treadmill also includes at least one light source that is adapted to selectively communicate information to an instructor relating to the parameter.
