Abstract: To improve the effect and the safety of Kaatsu training. A training system includes a tight fitting device which is intended to be placed around a compressed range of an arm or a leg and which has a pneumatic bag, and a training device adapted to control the compression pressure that is applied to a compressed range by the tight fitting device by means of supplying air to the pneumatic bag of the tight fitting device or removing the air from the pneumatic bag. The training device supplies the air to the pneumatic bag and removes the air from the pneumatic bag in such a manner that the compression pressure that is applied by the tight fitting device to the compressed range oscillates between an upper peak and a lower peak within a range lower than an appropriate pressure.

Abstract: Some embodiments provide an abdominal training machine that uses an adapted reverse crunching motion to minimize stress to the knees, back, shoulders, and neck when training the abdominal muscles. The machine combines weight resistance training with a replicated natural motion of each leg to produce the adapted reverse crunching motion. The adapted reverse crunching motion is performed using a section of the lower part of the body closest to the abdominal muscles while the upper body or torso remains stationary. In some embodiments, the abdominal training machine includes a frame, a body support member, and two individually rotating resistance members. Each resistance member includes a weight assembly for providing a user adjustable amount of resistance.

A cross bar is coupled to the pivot rails adjacent to the exterior ends. A plate is coupled to the pivot rails adjacent to the interior ends. The plate has recesses. The recesses receive and support attachments.

Abstract: An exercise treadmill having an endless exercise surface for walking or running while exercising, a resistance mechanism for providing a resistance for simulating the pushing or pulling of a load, wherein the resistance can be adjusted and set to a specific resistance setting. A movable pushing and pulling means is or are operatively attached to the resistance mechanism to transfer the load to the user. The resistance mechanism applies a constant and static force to the pushing and pulling means only in the same direction the endless movable surface moves and opposite a pushing or pulling direction such that operating the treadmill simulates the pushing or pulling of a load by a combination of gripping and pushing or pulling the pushing and pulling means forward or backwards while walking or running forward or backwards.

Abstract: An exercise machine has a user support movement arm rotatably mounted on a support frame for rotation about a first pivot axis, and a user support assembly pivotally connected to the movement arm for rotation about a second pivot axis so that the user support assembly rotates in two directions about different pivot axes. An exercise arm pivotally mounted on the frame is linked to the user support assembly or user support movement arm so that movement of the exercise arm automatically moves the user support assembly. Movement about one pivot axis may be a free pivoting, non-resisted movement while movement about the other pivot axis may be associated with a resistive load.

Abstract: A breathing apparatus structure with a two-stage reduced-pressure spare air bottle head is provided, which includes an air bottle head mounted at an outlet end of a spare air bottle and an inhalation mouthpiece, so as to provide an air at a suitable pressure to a diver or drowning person for emergency use. The air bottle head is sequentially provided with an air bottle head switch, a high pressure reducing valve, and a low-pressure valve connected in series on an air passage thereof. Thus, an air leakage of a high-pressure air in the air bottle can be avoided when the high-pressure air is not used, and the service life of elastic elements of the low-pressure valve can also be prolonged.

The handles or arms pivot together with and in the same back or forth direction as the pedals to which they are interlinked.

Abstract: A saddle for an exercise equipment for allowing a user to perform an exercise in a sitting posture is provided, which has the capability of suppressing variations in sitting posture to achieve stable exercise effects. The exercise equipment has a base, the saddle for supporting the user's buttocks, and a coupling mechanism configured to movably couple the saddle to the base such that a load acted on a leg by the user's own weight varies according to a relative positional displacement between a foot position and a position of center of gravity of the user, and also configured to limit a movable direction of the saddle such that a direction of the relative positional displacement between the foot position and the position of center of gravity is limited to a direction of flexion and extension of knee joint. The saddle has a pair of curved recesses at its outer periphery, which are configured such that parts of the femoral regions of the user fit the recesses.

Athletic data relating to a single person or group of people is collected at a central location, and subsequently displayed at a desired remote location so that the person or people can review and critique their performance. In addition, athletic data for multiple persons can be collected at a central location, and subsequently displayed to a user at a desired remote location, so that the user can compare his or her athletic activities to others.

Abstract: The invention is a bicycle trainer to which a standard bicycle temporarily attaches for exercise and simulated rides. A lifting mechanism raises and lowers the front tire, and in preferred embodiments, a frame engages the rear tire to hold the rear tire in an elevated position against a resistance cylinder. The resistance cylinder provides a force against rear tire revolution and varies the resistance to pedaling. The resistance cylinder can vary resistance against back tire revolution by pumping a resistance fluid into and out of the cylinder, by changing the position of the resistance cylinder in relation to the back tire, or by translation of the bicycle back and forth. In other embodiments, the trainer is electronically controlled to simulate real-world geographical courses programmed into a readable format for electronically maneuvering front tire and back tire positions as necessary to provide resistance to pedaling.
