A method of determining a more suitable appropriate pressure for use in muscle strength enhancement methods involving the restriction of blood flow. The pressure of air in a gas bladder of a compression band is temporarily increased to a pressure higher than a presumed appropriate pressure and then gradually reduced. During this process, a pulse wave amplitude is measured, and a maximum pulse wave pressure, which is the pressure of the air in the gas bladder at a time when the pulse wave amplitude that is temporarily increased and then reduced has its maximum value is specified by a maximum pulse wave pressure specifying unit 12E. The unit 12E sends maximum pulse wave pressure data representing a maximum pulse wave pressure to an appropriate pressure calculating unit 12F. The unit 12F multiplies the maximum pulse wave pressure by a coefficient to obtain an appropriate pressure.

A compression device for applying controllable compression to a portion of the anatomy of a user, includes a body, at least one memory wire embedded in the body and configured to contract in length upon application of a current so as to reduce an effective length of the body and apply a compressive force to the portion of the anatomy of the user, and a controller configured to selectively apply current to the memory wires to contract the memory wires and reduce the effective length of the body. The controller includes a circuit board supported by the body and a microcontroller mounted to the circuit board, the microcontroller programmed to actuate the memory wires according to a compression protocol stored in a memory associated with the microcontroller. Each memory wire has a first end fixedly connected to the circuit board and a second end fixed relative to the body.

The present invention relates to a golf swing training aid rod for teaching a golfer the proper golf swing and arm control for execution a golf stroke. In particular, the golf swing training aid rod includes an elongated shaft having a reference tip located at a first end of the elongated shaft and an attachment member located at a second end of the elongated shaft, and an axilla support member having an axilla side, an inner bicep side, and an attachment receiving member, the attachment receiving member is coupled to the attachment member of the elongated shaft, the axilla support member is configured to be inserted and held in place between an inner bicep and an axilla member of the golfer, and the golf swing training aid rod provides the visual and tactile feedback to the golfer while executing the golf stroke.

A tackle training system defines a frame configured for attachment to a player's body. The frame has an upper portion, a lower portion, and a center portion extending therebetween. The upper portion defines at least one attachment structure extending downwardly toward the lower portion, and the lower portion defines at least one attachment structure extending upwardly toward the upper portion generally vertically aligned with the attachment structure of the upper portion. The opposing attachment structures are for contacting opposing ends of a bar so as to removably attach and extend the bar between the upper and lower portions. The attachment structures of the frame limit movement of the removable bar generally to that of the frame and allow release of the removable bar from the frame when a force that overcomes an attachment force provided by the attachment structures is applied to the removable bar.

Various embodiments for a swing mechanics shoulder harness and barrel ax are described. The swing mechanics shoulder harness and barrel ax may be used to train an operator the proper biomechanical sequence of a swing. The swing mechanics shoulder harness and barrel ax includes a shoulder harness, a shoulder portion, a chest portion, a first coupling section, a second coupling section, and at least one wrist attachment.

An apparatus comprising a pair of gloves, wherein an index finger portion of a left glove is connected to an index finger portion of a right glove, and wherein a thumb portion of the left glove is connected to a thumb portion of the right glove.

A hand control device for swimmers is presented. The device has a main body with two holes in a side-by-side configuration. The first one of the two holes is configured for a third digit of a person's hand while the second one of the two holes is configured for a fourth digit of the person's hand. The inside surface of each hole comprises a plurality of grooves that run depthwise thereby providing wet traction while impacting minimum direct pressure on the nerves, vessels and tendons. The outside surface of the device may also include ridges to provide pass through for water.
