An exercise feedback system determines muscle fatigue measurements using physiological data generated by a sensor-equipped athletic garment. The muscle fatigue measurement is determined by analyzing the frequency spread of the physiological data. The exercise feedback system may customize exercise programs, determine risks of injury, or generate biofeedback for presentation on graphical user interfaces using the muscle fatigue measurements. The exercise feedback system accesses pre-determined muscle fatigue measurement models that define criteria for the aforementioned features. For instance, if an athlete is becoming fatigued and exercising with improper form based on a muscle fatigue measurement, the exercise feedback system modifies the athlete's exercise program to help target and improve the athlete's weaknesses as well as to prevent injury.

Systems and methods relating to evaluating the performance of a person playing basketball are described. The systems and methods can be used to provide an evaluation sequence that can determine and evaluate the performance level of a person at one or more basketball skills. The evaluation sequence for the person can include a first sequence of actions that are the same each person being evaluated for a particular skill and a second sequence of actions that is based on the results of the first sequence and may be different for each person. Once the first and second sequences have been completed by the person, the system can determine a performance level for the person for the skills being evaluated.

An exercise system comprises a stationary exercise apparatus including support arms, exercise parts, and a frame, at least one electromyograph configured to be worn on at least one body portion of a user, the electromyograph including an electromyogram sensor and a motion sensor, and a smart device configured to obtain a posture according to the detected motion, elect at least one exercise part corresponding to the posture from among the exercise parts, determine a target exercise part among the at least one exercise part elected, obtain a muscle strength by analyzing the detected electromyogram, record a muscle strength enhancement history in association with a use history of the determined target exercise part, and output the recorded muscle strength enhancement history and the use history.

Athletic performance monitoring systems and methods, many of which utilize, in some manner, global positioning satellite (GPS) data, provide data and information to athletes and/or to equipment used by athletes during an athletic event. Such systems and methods may provide route information to athletes and/or their trainers, e.g., for pre-event planning, goal setting, and calibration purposes. Such systems and methods optionally may provide real time information to the athlete while the event takes place, e.g., to assist in reaching the pre-set goals. Additionally, data and information collected by such systems and methods may assist in post-event analysis for athletes and their trainers, e.g., to evaluate past performances and to assist in improving future performances.

An example method for providing enhanced event visualizations based on location data includes receiving, by a visualization processor, location data and sensor data for a plurality of participants; determining an impact indication for two or more participants of the plurality of participants based at least in part on the location data and sensor data; determining, by the visualization processor, a location of impact based on the impact indication and the location data and sensor data for the two or more participants; and generating an impact visualization interface configured to visually indicate impact data associated with the impact indication proximate the impact location.

Gait analysis systems are provided with body support systems for user's self-adjustment of body weight force when ambulating with the body support systems. The gait analysis systems with the body support systems can be used with a treadmill or over a fixed surface for gait training and analysis with the ability to adjust the user's body weight force during the collection of gait data. Gait data for analysis is collected by an array of sensors mounted on the body support systems in various combinations for sensing gait movement, video imaging, heel strike and toe off states, video processing, feet pressure maps and electromyography.

The present invention discloses a modular brace, mountable on a joint, configured for exercising at least one muscle connected to, or otherwise affecting the function of, the joint, the brace comprising: lateral and medial rigid articulated cages, lateral and medial replaceable elastic members, and at least one joint-covering, replaceable elastic member. The lateral, medial, and at least one joint-covering, replaceable elastic members are configured to produce predetermined resistance force against muscles connected to the joint. The lateral and medial cages are configured for restriction of the joint's motion to the normal articulation of the joint. At least one joint-covering elastic member is adapted to simultaneously protect the joint from external insult while preventing pressure on the same.

Mouth guard that includes a flexible printed circuit board encapsulated within a base member is provided. The flexible printed circuit board includes multiple separate stiff sections spaced apart from each other within the base member. One or more electronic devices are disposed within the base member. In particular, the one or more electronics are disposed on the base member.

A system having networked exercise devices that can have a shared virtual exercise session for training, collaboration or competition. The exercise devices each have adjustable difficulty setting and a touch screen for displaying different virtual exercise sessions. The touch screen can display a representation, such as one or more avatars, that represent users of the exercise devices, and that have a virtual speed in proportion to exercise performance on the exercise devices. Dynamic adjustment can be made based on the collective performance of the exercise devices, to cause a same adjustment to a respective current difficulty setting of at least one, two or more exercise devices during the shared virtual exercise session. Virtual training can be provided by way of a chaser animation that chases the representation of the exercise devices, the chaser animation having a virtual speed in dependence of exercise performance of users of the exercise devices.
