Abstract: A swimming exercise device, comprising a restraint including an opening and a contact portion, the restraint configured to receive a head of a user through the opening and to restrain the user, via contact between shoulders of the user and the contact portion, such that the user is held substantially stationary during forward motion of the user against the restraint and an abutment structure configured to contact a pool surface and transmit forces associated with the forward motion of the user against the restraint to the pool surface.

Abstract: A range of motion limiting device, in one example comprising a first armature configured to engage a carriage moving on at least one rail having a first surface and a second surface transversely offset from the first surface of the rail. Also disclosed is an example utilizing a first bumper adjacent the first longitudinal end of the first armature. The first bumper extending transversely from the first transverse side of the first armature, optionally having a distal end with a non-slip surface engaging the first surface of a rail. Also disclosed is a second bumper longitudinally offset from the first bumper on the first armature, the second bumper extending transversely from the second transverse side of the first armature, also optionally having a distal end with a non-slip surface engaging the second surface of the rail.

Abstract: The invention is a trigger pull training device for improving trigger pull technique. The device has a frame with a trigger track opening and a trigger which goes through that opening. A proximity sensor or a plurality of proximity sensors are placed proximate the trigger track opening. The sensors are connected to an indicator whereby pulling the trigger such that the trigger is within the sensing zone causes the proximity sensor to emit a signal. A plurality of sensors can be lined along the trigger track opening to indicate the accuracy of any pull.

Abstract: An apparatus for physical fitness physical strength, agility and endurance training. A controllable pressurized flow of fluid is first received via a hose to a source of the pressurized fluid. In response to this flow of fluid, a force is generated along at least one of a plurality of selected directions using one or more apertures or nozzles. The force is then transferred to a user of the apparatus so as to supply physical resistance training to the user. The apparatus further includes a user engaging mechanism that is connected to the propulsion system, and is configured to transmit exercise forces to an associated user. The apparatus further includes controls for controlling the magnitude and direction of the reaction force vector applied to the user engaging mechanism. Various embodiments of user engaging members, including blocking dummies, handles, gloves, helmets, shoes, straps or balls, may be attached to the propulsion system.

Abstract: An improved method and apparatus for physical strength, agility and endurance training uses fluid jet reaction forces to train and strengthen muscles. The device for physical training includes a source of pressurized fluid connectable through a hose to a propulsion system and one or more apertures or nozzles for forming one or more jets of fluid that are discharged from the propulsion system such that a nozzle reaction force, acting in a direction opposite the direction of the jet stream, is exerted on the jet propulsion system. Fluid can also be delivered through a curved tube or passage in the propulsion system such that a stream of fluid that is discharged from the propulsion system is not traveling in the same direction as it was before it was discharged such that the change in direction of the fluid causes a change in the momentum of the fluid for exerting an additional reaction force on the propulsion system.

Abstract: Systems and methods for measuring the pressure exerted between or within anatomical masses/structures, as well as the position and/or spatial dimensions of an anatomical structure. According to a preferred embodiment, the invention comprises a sensor element positionable between anatomical structures or within an anatomical structure. The sensor is operative to generate a signal indicative of the pressure being exerted therebetween or therewithin. The sensor may be operative to measure spatial dimensions between structures or within a structure. A monitor coupled to the sensor receives a signal generated thereby and provides an indication as to the spacing or pressure being measured. The systems and methods may be utilized in diagnostic tests or surgical procedures.

Abstract: An apparatus and method evaluate the power of a muscle or a muscle group by initializing a resistance element to a first resistance level. An engagement assembly coupled to the resistance element is moved at a highest achievable velocity through an exercise stroke while a representative velocity at which the engagement assembly is moved through the exercise stroke is measured. At the completion of the exercise stroke, the resistance level of the resistance element is increased and the exercise stroke is repeated. The resistance level is increased until the resistance level is sufficient to preclude moving the engagement assembly through a complete exercise stroke. The power for each exercise stroke, the maximum power and the velocity and resistance at which the maximum power is produced are calculated based on the resistance level for each exercise stroke and the representative velocity for each exercise stroke.

Abstract: A body motion detector, to be attached to or carried by a user for detecting body motions of the user, uses a plurality of sensors each for detecting body motions in a specified direction to output a body motion signal according to the user's body motion. These sensors are disposed so as to detect the body motion in different directions. One of these sensors are selected by carrying out calculations on signals outputted from the sensors. The user's body motion is detected by using selectively output signals from the selected body motion sensor. The body motion detector may also include a component for detecting the orientation of the body motion detector itself from signals outputted from these sensors and another component for detecting the user's body motions by carrying out calculations on the signals outputted from these sensors, corresponding to the orientation as detected by the orientation detecting component.
