A resilient rod that provides adjustable directional resistance is disclosed. In one aspect of the invention, a resistance level may be determined based on a thickness of the rod and a position of an applied force with respect to a fulcrum point. In another aspect of the invention, at least one spine may be attached to the beam to increase a diameter of the beam along one axis. The resistance level may be determined based on the thickness of the rod, the position of the applied force and an orientation of the at least one spine with regard to the direction of the applied force. In other aspects of the invention, the resilient rods may be incorporated into a golf club that provides for adjustable resistance levels.

A system and method for adaptive fitness testing is provided. A fitness testing application manages fitness tests on a fitness testing apparatus by collecting physiological data and calculating various performance metrics. The fitness testing application automatically reconfigures fitness tests to adopt to a user's improving fitness level.

Systems and methods for determining a time of a passing at a reference line of an RFID tag traveling along a route and a time of lapsing of the tracked RFID tag on the route, the system have a plurality of spaced apart tag reader systems for wirelessly obtaining tag reads, wherein at least one of the tag reader systems is space apart from the reference line. The timing system receives a plurality of tag reads and determines the time of passing of the RFID at the reference line responsive to the plurality of received tag read messages received from the plurality of tag reader systems.

A method for identifying and correcting muscular and skeletal disbalances through exercise includes recording, by a processor, using at least one sensor coupled to the processor, an exercise motion performed by a user, identifying, by the processor, a motion deficiency of the user based on the detected exercise motion, formulating, by the processor, a corrective motion based on the detected motion deficiency, and providing, by the processor, the corrective motion to the user, which also includes identifying motion deficiencies as far as range of motion, balance, symmetry, smoothness, strength, stamina and other motion characteristics, formulating corrective exercise program that involves multiple training machines, formulating exercises in terms of number of repetitions, cadence (frequency) or motion, range of motion, added resistance levels, communicating the corrective exercise program via the screen embedded on each machine, and guiding the user through each exercise, directing user to change exercise machines.

Method for coupling a sensor to a piece of equipment, such as a golf club, baseball bat, or tennis racket, that ensures that the sensor is in a known position and orientation relative to the equipment. Compensates and calibrates for degrees of freedom introduced in manufacturing and installation. The method may include manufacturing a sensor receiver that aligns with equipment in a fixed orientation, and that holds a sensor housing in a fixed orientation relative to the receiver. Remaining uncertainties in sensor position and orientation may be addressed using post-installation calibration. Calibration may include performing specific calibration movements with the equipment and analyzing the sensor data collected during these calibration movements.

An athletic performance data system has an athletic field data collection system for obtaining athletic performance data and athlete identifying information for plural athletes at an athletic performance event. An athletic data host server receives the athletic performance test data and athlete identifying information from the athletic field data collection system, and the athletic performance data and athlete identifying information are posted to an athletic performance web site in a separate, personalized page for each of the plural athletes.

A wearable device assembly has a housing supporting a controller, display and indicator system thereon. The controller has at least one sensor wherein activity of a user wearing the device is detected. The controller selectively illuminates the indicator system to indicate a level of activity of the user.

A practice wall for sports having a plurality of panels arranged in a series of rows and columns. The columns are joined by hinges such that the columns can be folded to create various profiles which will cause a ball to reflect differently depending on the goals of the athlete. In one embodiment the panels can be readily disassembled so the wall can be temporarily erected, stored, and reassembled. In some embodiments the inventive practice wall can be fitted with instrumentation to provide objective performance data to the athlete or a coach.

An exercise accessory includes a load bearing element. It further includes a haptic actuator. In response to an indication of an event pertaining to a load on the load bearing element, the haptic actuator is configured to generate a vibration pattern corresponding to the event. Different events are associated with different vibration patterns.

The invention pertains to a stationary exercise bike along with a display that provides instruction to lead a rider through an exercise program. The invention allows a rider to obtain benefits of a group, instructor-led class though the rider's schedule does not permit the rider to participate in the class. The invention also describes a method of exercising with the foregoing bike and display.
