The present invention provides a garment (1) for covering a wearer's thighs. The garment comprises a pair of front resistance elements (6) each of which, in use, extends obliquely across the front of a respective one of the wearer's thighs. It also comprises a pair of rear resistance elements (10) each of which, in use, extends obliquely across the rear of a respective one of the wearer's thighs. Each of the front and rear resistance elements extends from a respective upper position (7, 11) located proximal to the midline (8) of the garment to a respective lower position (9, 12) located distal from the midline of the garment. This provides a stabilizing effect on the wearer's hip joint.

A training system is provided herein that includes a training device and a timing device. The training device includes a frame, one or more pulleys operably coupled with the frame, and a cable routed through the one or more pulleys. The timing device is coupled to the training device and includes a housing operably coupled with the training device, a sensor configured to detect motion between a first position and a second position, and a computing system positioned within the housing and operably coupled with the sensor. The computing system is configured to calculate a time between the first position and second position. The calculated time is provided on one or more displays of the timing device.

Various embodiments provide an apparatus and method to detect timing components of a timing system. A processor sends signals to timing components and compares the responses with each other and with stored characteristic responses to detect if a timing component is present, if its characteristics have changed, to identify the connected timing component, and, if communication protocols are used, exchange data.

Described herein are systems and methods for favorably coordinating a timing relationship between a musculoskeletal activity cycle and a cardiac cycle of a user. A method may include repetitively detecting a signal that correlates to a blood volume in the user; determining an actual value of the signal that varies with the timing relationship; computing a trend of the actual value of the signal; and adjusting the movement guidance based on the trend of the actual value. A system may include a prompt device configured to provide recurrently a movement guidance to the user for guiding performance of the rhythmic musculoskeletal activity; a sensor configured to provide a signal that correlates to a blood volume in the user; and a processor configured to determine an actual value of the signal that varies with the timing relationship and to adjust the movement guidance based on the trend of the actual value.

The present invention relates to an exercise analysis system using a sensor worn on a user's head, and more specifically, to an exercise analysis system for measuring acceleration signals according to movement of a user's head using an accelerometer worn on the head, and separately analyzing exercise postures corresponding to the movement of the head by identifying user's left and right, front and rear, or up and down direction from the measured acceleration signals.

In one aspect, a swimjet system may include a reverse thrust system worn by a swimmer proximate the frontal upper torso. The system provides a variable amount of reverse thrust such that the user can swim-in-place or make gradual forward progress. Importantly, this may enable a user to effectively “extend” a small residential pool to serve the same function as a twenty-five meter pool typically found at commercial or government facilities. The system also provides laminar current under the user while swimming, which solves the problems of “leg drop,” the need to “out-kick” the arm stroke, and turbulence and wave action around the head associated with conventional swim-in-place devices. Still further, in certain embodiments the system provides a relatively strong current in the region of the arm stroke moving away from the swimmer which provides enhanced “resistance” for proficient swimmers.

A swim platform with a higher level of performance offered by an increase in the horizontal velocity and force off of the swim platform, thus enabling the athlete to enter the water further from the start. The athlete having full control over adjustments can create an optimal setup for their specifications.
