Abstract:
A boat including a frame and a diving board mounted to the frame. The diving board includes a base and a board coupled to the base at a pivot location. The board extends from the pivot location to a distal end. An axial spring is interconnected between the base and the board for cancelling out forces which are imparted by a user jumping on the board at the distal end.
Abstract:
A portable exercise device (41) for releasable attachment about a movable joint of a user's body. The device (41) comprising at least one selectively variable resistance hub (2) for location on a pivot axis of the movable body joint, first attachment means (1, 6) extending from the hub (2) for releasable connection to the body at a first side of the joint, and second attachment means (3, 4, 9) extending from the hub for releasable connection to the body at a second side of the joint which is opposite the first side. The first attachment means (1, 6) being pivotably engaged with the hub (2). The hub (2) includes a resistance device which is in the hub (2) and which is engaged with part of the first attachment means (1, 6). The resistance device comprises a fluid and a rotor (16). The in use rotor (16) acts against the fluid as the first attachment means (1, 6) is pivoted.
Abstract:
An exercise apparatus comprising a drive device (13), an exercise element (11) and a torque transmitting device (12) connecting the driving device (13) and the exercise element such that, for a given speed of rotation of the driving device (13), the torque applied to the exercise element (11) and accordingly the resistance to movement provided by the exercise element (11) is substantially constant. A user interface (10) is provided as part of the exercise element (11) such that resistance to movement exhibited by the exercise element is translated via the user interface into a resistance against which the user may perform work. A sensor (14) is connected to the exercise element (11) to monitor direction and magnitude of movement of the element (11) and the output of the sensor (14) is fed to a control unit comprising a control processor (20), the sensor output signal being connected to the processor (20) via a sensor interface circuit (21). The processor (20) also drives a drive control and interface circuit (22) and the drive control and interface circuit (22), in turn, control the speed of the drive device (13) in accordance with a programme stored in the processor (20). The exercise programme to be performed on the apparatus is loaded into the control processor (20) via a dedicated keyboard (23) and the programmed routine is displayed on a dedicated display (24). During an exercise programme, data relating to the exercises already performed is displayed on the dedicated display (24) and, after the programme has been completed, statistics relating to the total programme performed are displayed. A optional external computer (31) may also be linked to the control processor (20), via a suitable interface (33), such that predefined exercise programmes, stored in a programme storage device (31) of the external computer (31) may be used via the interface (33).
Abstract:
A workout apparatus 10 includes base 12. A lifting arm 14 is pivotally connected to base 12 and movable on base 12 between a raised position and a lowered position, the lifting arm 14 including a first end 14a pivotally connected to base 12 and a second end 14b opposite the first end, the second end 14b including a gripping end piece 16. At least one weight post 32 extends outward from lifting arm 14 at a location between first end 14a and second end 14b of lifting arm 14. A braking system 18 is mounted to base 12 and coupled to lifting arm 14. Braking system 18 allows lifting arm 14 to move toward the raised position freely. Braking system 18 is engaged as lifting arm 14 moves towards the lowered position to lower lifting arm 14 toward the lowered position at a controlled rate of speed.
Abstract:
A system and method for cardiovascular exercise stress magnetic resonance using a MRI-compatible treadmill and real-time imaging. The treadmill comprises non- ferromagnetic components so that it may be used in proximity to a MRI scanner. The treadmill is positioned adjacent to the MRI scan table. A treadmill control system is used to control the speed and grade of the treadmill to allow it to perform a wide range of exercise protocols. Patients complete an exercise protocol on the treadmill and are then moved to the MRI scan table. Images are acquired as quickly as possible post-exercise to more accurately diagnose cardiovascular disease in patients.
Abstract:
The present invention relates to a low-impact, time-efficient way to exercise both the cardiorespiratory system and the muscular system, particularly the abdominal and back muscles. The exerciser uses his muscles to oscillate a pivoted carriage within a frame. In one embodiment, the exerciser pedals a crank to pump hydraulic fluid through a hydraulic circuit to a hydraulic cylinder connected between the carriage and the frame so as to urge the carriage to oscillate with respect to the frame. A limit sensor detects when the carriage is positioned at one extreme of its oscillation and signals the hydraulic circuit to reverse the flow of hydraulic fluid to the hydraulic cylinder.
Abstract:
This invention is an exercise device comprising a variable speed rotary driving device (10), an adjustable speed control (90) for the rotary driving device, an exercise link (70) offering resistance to motion of the user, and a hydraulic coupling (30) connecting the variable speed rotary driving device to a torque multiplier (40). The exercise device operates such that torque is transmitted to the exercise link (70) to impart resistance to motion of the link (70), the resistance to motion is variable, a consistent function of the speed, direction of the link (70), and of the variable speed rotary driving device (10).
Abstract:
An arm wrestling machine (101), comprising: a bench comprising a generally planar top member (102) and a supporting framework; a plurality of elongate levers (112-114) mounted to said bench at respectively different pivot points for rotation thereabout, said levers having an upper portion extending above the top member and a lower portion extending below the top member; and a linkage (216) between said plurality of levers, said linkage connecting to the lower portion (210-212) of each said lever and configured to transmit force between said levers.
Abstract:
Movement-fixing means for a person (10). The problem of the invention is to propose a movement-fixing means in which a person in the standing position can be fixed at a certain location, while at the same time maintaining his ability to execute free walking movements in any direction. The problem is solved by a movement-fixing means comprising a guide element (2) with vertical orientation, a means for attaching the guide element to the person's centre of gravity, means (11-14) by way of which a force which crosses over the vertical orientation is introduced to the person above his centre of gravity, and two shoes (15) for the person with means for varying the coefficient of friction on an underlying surface (5).
Abstract:
The present invention relates to an exercise apparatus for exercising muscle groups in a person's legs by stretching and/or retraction, which exercise apparatus comprises at least a first frame and at least a first foot platform which foot platform is rotatable fastened to a bearing, which bearing is placed in relation to the person's foot for exercise at least plantar flexion and/or dorsal flexion, which exercise apparatus further includes a leg support. Hereby can be achieved exercising of the muscle groups by stretching and/ or retraction (quadriceps femoris, biceps femoris, semitendinosus, semimembranosus, gastrocnememius, tibialis posterior, tibialis anterior, peroneus longus, peroneus brevis and soleus) in the legs of a person, and the muscles (soleus, gastrocnemius, tibialis posterior, peroneus brevis, peroneus longus, biceps femoris, semitendinosus, semimembranosus) at the back side of the legs.
