The present invention relates to delivery of content that is driven by input from one or more performance sensor units, such as performance sensor units configured to monitor motion-based performances and/or audio-based performances. Embodiments of the invention include software and hardware, and associated methodologies, associated with the generation, distribution, and execution of such content. Attention is paid to implementations whereby performance sensor units provide input to an adaptive training program.

A support shirt comprising a shirt body and a pair of shirt body sleeves positioned adjacent to an upper shirt body is provided. The sleeves are attached to the shirt body at sleeve body holes, with each of the sleeves including sleeve reinforcement regions extending at least a portion of the distance from the sleeve holes to an outer edge of the sleeves. The sleeve reinforcement regions extend substantially along a centerline extending longitudinally across the sleeves and the upper sleeve body to stabilize and provide support to the shoulders of a wearer during an upward lifting motion.

A rowing machine convertible for use both indoors and outdoors. In the outdoor mode, the rowing machine is configured for adaptation to a watercraft, such as a kayak or stand up paddle board (SUP). A rower operating the rowing machine pulls on a rope or cord to cause paddles positioned at the rearward end of the machine to rotate and move the machine on a body of water. In the indoor mode, legs are attached to the machine for placement on a rigid surface. The paddles are placed in a container holding fluid.

An exercise machine includes a cyclical actuator and a mechanical energy storage device. Connective structure operatively connects the cyclical actuator to the mechanical energy storage device. Motion of the cyclical actuator urges physical motion of and energy storage in the mechanical energy storage device. The exercise machine further includes an electric machine. A communication pathway enables exchange of data between multiple associated exercise machines such that multiple associated operators on multiple associated exercise machines have a common experience.

Methods, apparatus, systems and articles of manufacture for measuring and adjusting physical resistance for athletic activities and fitness equipment are disclosed. An example system includes a user-wearable sensor to measure a first level of physical effort during a first athletic activity using fitness equipment and to generate sensor data indicative of the measured first level of physical effort. The example system also includes a controller to receive the sensor data to perform a comparison of the sensor data and data from second athletic activity indicative of a second level of physical effort, and automatically generate a control signal to adjust a setting of the fitness equipment based on the comparison.

An integrated apparatus and method of use for testing the equipment used in rowing watercraft is disclosed. The invention functions to test the output of a coxswain's box as well as its chargers and speakers to assure they function during rowing events, including but not limited to practice and competition. The invention comprises a cox box battery charger test gauge, a stroke rate recording tester, an external speaker tester, and a cox box speaker tester. It allows for bench testing of equipment as well as checks on the water to assure proper functioning of the cox box during use. The device is capable of working with cox boxes available from various manufacturers.
