An exercise device includes pedals, a belt and a hydro-kinetic brake. A user applies muscular force to the pedals and the pedal belt transfers the motion of the pedals to a flywheel shaft of the fluid brake. The pedals may be configured to accept force from a hand, foot, arm, leg and / or neck of the user. The amount of work performed by the user is derived by measuring the relative rotational speeds of two radial-blade impellers of the fluid brake. The wattage exhibited by the fluid brake during the exercise session may be recorded and associated with an identified user, whereby records of the exercise performance of an individual may be updated.

A training device measures, after its robot arm is mounted on a trainee, a change in angle of the joint axles of a limb of the trainee with angular sensors. Based on the angular change measured, a controller calculates an angular rate in the direction in which a load is applied, stores as the maximum muscular force a load at the time when the angular rate has exceeded a predetermined value, and stops applying the loads.

A training device isolates muscular force direction from force magnitude to provide improved feedback to a user over conventional exercise equipment which implicitly conflates magnitude and force direction in producing purely kinematic feedback.

In an apparatus for resistance-based muscular force evaluation and training, elasticity at the distal end of a robot arm is made to follow changes caused in the force exerted by the muscles of praxis as a result of changes in angle at the first and second joints. Even when the trainee changes his or her position, he or she may be indicated of and may positively comprehend the direction in which he or she is to exert the force. The robot arm have its distal end secured to the distal end of the link mechanism has elasticity variable with directions. The elasticity is varied to follow changes caused in the force exerted on the distal end of the link mechanism by a set of antagonistic mono-articular muscles and a set of antagonistic bi-articular muscles, as a result of changes in angle at the first and second joints.

A resistance training device effectively training the muscular force of a desired muscle includes a saddle for a user to sit on, a robot arm adjustable to the length of a limb of the user, a fastener for securing the robot arm to the limb, a controller for controlling the torque of a driving source driving a joint of the robot arm, and an input operating unit for the user to input a driving condition. When the user inputs a training load and an output direction of the distal end of the limb to be trained, the value of a torque necessary for generating the training load is calculated. The robot arm generates the torque of the calculated magnitude acting in a direction opposite to the output direction in such a manner that a constant training load is exerted to the user without dependency on the position of the user.

An archery apparatus includes a combined adjustable neck support, handle and release mechanism for reducing the amount of force exerted by an archer to maintain a bowstring and associated arrow in a generally fully drawn position. In operation, the release mechanism is secured to the bowstring, the handle is grasped by the drawing hand of the archer, with the other hand of the archer on the bow frame, the bowstring is drawn by the archer to the generally fully drawn position so that the release mechanism is proximate the side of the head of the archer and the neck support is selectively and supportably disposed against the archer's neck. Thus, both the manual muscular force exerted by the drawing arm of the archer and the force supplied by the neck support are available in tandem for maintaining a bowstring and associated arrow in a generally fully drawn position. The release mechanism is then actuated to provide the normal proper triggering of the arrow into flight.

It is intended to provide a muscular tension-elevating agent obtained from a fruit, i.e., a muscular tension-elevating agent and a body fat-controlling agent originating in a natural material which reinforces muscular force and shows effects of reducing body fat and inhibiting body fat accumulation without lowering the skeletal muscle amount or the inner organ weight. More specifically speaking, it is intended to obtain polyphenol from a fruit and utilize the same in a muscular tension-elevating agent, a body fat-controlling agent or a drink, a food and a drug for elevating muscular tension, reducing body fat and inhibiting body fat accumulation. Namely, a muscular tension-elevating agent or a body fat-controlling agent containing, as the active ingredient, polyphenol originating in a fruit which is efficacious in elevating muscular tension and a drink, a food and a drug containing the same.

The present invention discloses an upper arm module of a wearable muscle strength assisting device, comprising: a base part connected to the body of a wearer and provided corresponding to the upper end part of the upper arm of the wearer; an upper arm part having one end rotatably coupled to the base part about a fixed point, extending to correspond to an upper arm of the wearer, and coupled to the upper arm of the wearer; an elastic body having one end fixedly coupled to a position spaced apart from one end of the upper arm portion in a direction in which the upper arm portion extends; a first link, one end of which is rotatably coupled to the base portion at an action point provided apart from the fixed point, and which is coupled to the upper arm portion so as to guide the other end tomove when the upper arm portion rotates about the fixed point; and a second link rotatably coupled to the other end of the first link at a first point, coupled to the upper arm portion to guide movement of a second point spaced apart from the first point when the upper arm portion rotates about the fixed point, and coupled to the other end of the elastic body at a third point spaced apart from thefirst point and the second point.
