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. At least one light source is configured to selectively emit a light regarding the treadmill.

A fitness tracking system for generating movement variables corresponding to movement of a user includes a monitoring device, a personal electronic device, and a remote processing server. The monitoring device is configured to be worn or carried by the user and includes a movement sensor configured to collect movement data. The personal electronic device is operably connected to the monitoring device. At least one of the personal electronic device and the monitoring device is configured to calculate feature data by applying a set of rules to the movement data, to calculate raw speed data corresponding to a speed of the user from the subset of the movement data, and to calculate raw distance data corresponding to a distance moved by the user from the subset of the movement data. The remote processing server includes a machine learning model for processing at least the feature data.

An exercise treadmill is disclosed. The treadmill can include one or more sensors to acquire input data. A computer system can trigger one or more actions based on the input data. The input data can correspond to a lengthwise position of the user along a length of a usable surface of the platform and/or a lateral position of the user on the belt. The action(s) can include providing feedback to the user and/or adjusting rotation of the belt and/or a resistance of rotation of the belt. The adjustment can be performed in response to input from a user control requesting the adjustment.

A method, apparatus, or system for modifying and assessing gait asymmetry is disclosed. The method, apparatus, or system may include measuring a first baseline step time for a first leg of an individual and a second baseline step time for a second leg of the individual and determining a first target step time for the first leg and a second target step time for the second leg. The first target step time can be different from the second target step time. The method may further include generating a series of auditory cues comprising a first cue duration corresponding to the first target step time and a second cue duration corresponding to the second target step time for synchronizing the first baseline step time and the second baseline step time with the first target step time and the second target step time, respectively. Other aspects, embodiments, and features are also claimed and described.

An electronic device may comprise audio processing circuitry, pace tracking circuitry, and positioning circuitry. The pace tracking circuitry may be operable to selects a tempo of songs for playback, by the audio processing circuitry based on position data generated by the positioning circuitry, a desired tempo, and whether the songs are stored locally or network-accessible. The position data may indicate the pace of a runner during a preceding, determined time interval. The pace tracking circuitry may control the song selection and/or time stretching based on a runner profile data stored in memory of the music device. The profile data may include runner's distance-per-stride data. The electronic device may include sensors operable to function as a pedometer. The pace tracking circuitry may update the distance-per-stride data based on the position data and based on data output by the one or more sensors.

An elliptical exercise machine may include a base, one or more upright stanchions coupled to the base and extending upward from the base and supporting first and second cranks. The first crank may support a first crank arm. The first crank arm may support a first pedal leg hanging downward from the first crank arm. The first pedal leg may support a right pedal. The right pedal may be configured to swing forward and rearward and to raise upward and lower downward. The second crank may support a second crank arm. The second crank arm may support a second pedal leg hanging downward from the second crank arm. The second pedal leg may support a left pedal. The left pedal may be configured to swing forward and rearward and to raise upward and lower downward.

The invention is comprised of a differential air pressure exercise system, comprising: a base; a pair of uprights on the base dividing the base into a front portion and a rear portion; a bulkhead extending between and vertically moveable relative to the uprights; a right arm attached to the bulkhead extending from the bulkhead towards the base rear portion; a left arm attached to the bulkhead extending from the bulkhead towards the base rear portion; a chamber support frame coupling element on the right arm; a chamber support frame coupling element on the left arm; at least one hinge coupled to the bulkhead between the left arm and the right arm; a chamber support frame extending between the left arm and the right arm, the chamber support frame coupled to the at least one hinge to move between an engaged condition wherein a portion of the chamber support frame is coupled to the chamber support frame coupling element on the right arm and a portion of the chamber support frame is coupled to the chamber support frame coupling element on the left arm and a lowered condition wherein the chamber support frame is uncoupled from both the chamber support frame coupling element on the right arm and the chamber support frame coupling element on the left arm.

To provide a walking state determination apparatus that can accurately detect a walking state of a person by performing simple calculation processing. The walking state determination apparatus determines the walking state of the person (for example, whether the state of the leg during the walking training is in a swing state or a stance state), and is suitable for determining the timing to assist a trainee. The walking state determination apparatus includes a distance measurement sensor attached to a prescribed part of a lower limb of the person and a calculation unit configured to determine the walking state of the person based on a distance from the distance measurement sensor to a floor surface detected by the distance measurement sensor.

Systems and methods for electronically conducting a fitness activity challenge are disclosed. The method may include first collecting electronic fitness data related to a first fitness activity, collecting second electronic fitness data related to a second fitness activity, generating comparison data by comparing the first electronic fitness data and the second electronic fitness data, and displaying the comparison data.
