A system and method for analyzing and improving the performance of a body motion of an animal or human subject requires instrumenting a subject with inertial sensors, monitoring a body motion of interest, converting sensor data into motion data and animation, comparing the motion data with existing data for motion related performance parameters, providing a real-time, information rich, animation and data display of the results in color coded displays; and based on the results prescribing a training regime with exercises selected from a library of standardized exercises using standardized tools and training aids.

An ink blend consisting of a polymer, a weakly cross-linking agent and a nanomaterial deposited to form a thin polymer-nanomaterial composite film with unique mechanical and electrical properties suitable for high performance strain sensing applications.

Vehicle simulators assist a rider with balancing a human-supported vehicle (e.g., bicycle, motorcycle, scooter, skateboard, etc.) by laterally displacing two pivot points supporting the vehicle without longitudinally moving the vehicle. The lateral displacement may be human-controlled, and need not require a wheel rolling on a belt or roller. The vehicle simulators feature mechanisms to laterally translate a front portion (e.g., a front wheel) and a rear portion (e.g., a rear wheel) of the vehicle such that a rider may balance the vehicle by steering. Advantageously, embodiments allow the vehicle to be laterally translated such that the rider may balance the vehicle in the same manner as when riding on a road, thereby providing a more realistic experience than prior-art simulators (e.g., stationary bicycle trainers) that do not allow the vehicle to be laterally translated and therefore do not require the rider to balance the vehicle.

Connecting straps, for use for example in sports activities, include (a) a sleeve of webbing having a first end and a second end and having a loop at each end, each loop having a base and a free end, (b) disposed within the sleeve of webbing, a band of elastic material extending in a continuous loop, and (c) an attachment strap, adjacent each loop, configured to secure a portion of the band to the webbing at the base of each loop. In some cases, the band has a solid, polygonal cross-sectional shape.

The bicycle ramp of the present invention is foldable and easily transportable. The bicycle ramp of the present invention may be built directly onto a utility trailer with a foldable gate and wheels and thus is transportable to be pulled along the back of a suitable vehicle using the hitch. The bicycle ramp of the present invention creates an inclined surface for bicycle riding applications, including the teaching of a beginning cyclist skills such as balancing and pedal. There is a receiving slot to engage the rear wheel of the bicycle at the flat upper section of the bicycle ramp. The receiving slot stabilizes the bicycle in a static position until a releasable stopper is released to launch the rider down the angled sections of the bicycle ramp.

A foot and hand pedaled bicycle assembly that facilitates a full body working during riding includes a bicycle that has a front wheel, a rear wheel and a frame. The frame has a top member and a lower member that each pivotally extends between a seat post and a handlebar fork. The handlebar fork is urgeable toward or away from the seat post. A pair of pedals is provided and each of the pedals is rotatably coupled to the frame for rotating the rear wheel. A pair of hand cranks is provided and each of the hand cranks is coupled to the handlebar fork for steering the bicycle. Moreover, each of the hand cranks is in mechanical communication with the front wheel for rotating the front wheel when the hand cranks are cranked.

The function of this invention is to provide exercisers with a safe and easy way to convert a legs-only exercising device, such as a stationary trainer or bicycle, with the capacity to exercise their upper and lower body muscle groups simultaneously or separately. This invention is portable and can be moved easily from one legs-only exercising device to another. Once they are mounted onto the handlebar or attachment bar of the legs-only device, it is now a full-body trainer. Exercisers mount the trainer, place their feet on the cycling pedals, place their elbows onto the elbow holders, grasp the hand grips, and now start their full body exercising activity. The degree of difficulty of their exercise trek is easily accommodated by allowing the rider to adjust the resistance for moving the forearm bars up and down for an upright bike, or back and forth for a recumbent trainer.

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.
