A training device may include a plurality of elongate shafts and at least one hinge structure interconnecting a pair of elongate shafts of the plurality of elongate shafts. The at least one hinge structure may be configured to allow a user to pivot the pair of elongate shafts relative to each other to select a desired angle between the pair of elongate shafts. In various embodiments, the at least one hinge structure comprises a hinge mechanism configured to be adjustable in discrete angle increments. Generally, the training device may be utilized in multiple configurations and may be adjusted and deployed in multiple different patterns to facilitate variable training exercises

A running form training device for training a runner to properly position and move their arms includes a harness, a pair of bands, and a pair of cuffs. The harness can be donned by a user so that the harness is removably engaged to a torso of the user. The bands are resiliently stretchable. Each band is engaged to the harness so that the band extends from proximate to a front of a respective shoulder of the user. Each cuff is engaged to a first end of a respective band and is removably engageable to a respective wrist of the user. The bands draw the arms of the user toward the harness, thereby restricting movement and positioning of the arms to promote proper running form.

An exercise weight unit adapted to be handheld and palm-centered comprising a body and a feature at an end of the body configured to create a slight inward torque when the weight unit is held in a hand of a user during physical sports training, wherein the feature is one of a hook shape, a mushroom shape and a fin shape.

The present invention provides a ski training device designed to assist an instructor to teach a beginner skier how to ski. The ski training device includes a front portion with a gripping section for the beginner skier, a back portion with a gripping section for the instructor, two side portions that connect the front and back portions, and an internal cavity between the front portion, back portion, and side portions, configured for the beginner skier.

Described herein are systems and methods of guiding a user to achieve musculoskeletal counterpulsation. A method may include receiving a cardiovascular cycle signal from a first sensor; determining a heart rate of the user based on the cardiovascular cycle signal; receiving a rhythmic musculoskeletal activity timing signal from a second sensor; determining an actual musculoskeletal activity cycle (MSKC) to cardiovascular cycle (CC) timing relationship; comparing the actual MSKC to CC timing relationship to a target MSKC to CC timing relationship; providing a recurrent prompt to the user as a timing indication for performance of a rhythmic musculoskeletal activity to guide the user to achieve a musculoskeletal activity cycle rate (MSKR) that approaches the target MSKC to CC timing relationship; and altering a feature of the recurrent prompt based on a determined alignment between the actual MSKC to CC timing relationship and the target MSKC to CC timing relationship.

Athletic performance sensing and/or tracking systems include components for measuring or sensing athletic performance data and/or for storing and/or displaying desired information associated with the athletic performance to the user (or others). Such systems can allow users a wide variety of options in creating workouts, selecting and presenting media content during the athletic performance, etc., e.g., to help keep users entertained and motivated. In some instances, user feedback may be used, optionally in combination with objective data relating to a workout, to control features of the workout routine, to control the music or other media content selected and/or presented, and/or to control features of future workout routines and/or the presented media content.

The present disclosure relates to on course rating systems (OCRS) and, more particularly, to its pace targets on cross country or road race course segments and related systems and methods of use. The method includes: obtaining performance equivalences (PEQs) of a first rated course including a track equivalent time of the first rated course; and obtaining a goal time, the equivalent of the first course but on a second course; and providing pace targets on selected segments for the second rated course using the track equivalent time and the goal time in order to cumulatively produce the goal time of the second rated course.

A pacing system signals runners with lights indicating if the runner is ahead or behind a preset pace as the runner proceeds around a running track. The system includes a controller that provides pace setting, start, stop, pause, and reset functions; pacing stations (e.g., 20) that are placed at intervals around the running track; and a cart for transport and battery charging. Paces are setup in the controller with a specific number of laps and a time per lap. Bright LED lights in LED matrices in the pacing stations signal the runners outdoors in sunlight. The controller wirelessly communicates with the pacing stations to signal the pacing stations to light at intervals determined by the preset pace. The system may support two or more simultaneous paces and variable pacing per lap to accommodate multiple runners.

There is described an integrated unweighted gait training system having an unweighting system comprising a computer controller; a gait measurement system in communication with the controller; and a display in communication with the computer controller adapted and configured to provide real-time feedback to a user of the integrated unweighting gait training system. The unweighting system may be a differential air pressure (DAP) unweighting system or a non-DAP unweighting system.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.
