The present invention provides a sports mask for breathing training. The sports mask includes a head assemble containing clips to hold the mask against the head. The sports mask further includes a face band assembly that includes straps that are received by the clips present on the head assembly to hold the face assembly against the face of a user. The face assembly includes a face mask unit comprising an airflow valve. The airflow valve includes an airflow resistance varying module that helps in varying flow of air into the airflow valve. The control of airflow resistance varying module can be either manual or automatic when the mask is connected to a wearable device or a vital parameter collection device.

An exercise machine support system for providing increased versatility including inclination or declination of an exercise surface, a reduction in the overall length and width of the exercise machine, and an enhanced user interface which reduces the risk of injury. The exercise machine support system generally includes a cantilevered exercise machine which is adapted to have a variable angle of incline or decline with respect to a horizontal ground surface. The exercise machine will generally include a base and a support which extends between the base and the exercise machine. The upper end of the support is connected to the exercise machine by a first pivot such that the exercise machine pivots about the support. An adjustment device may be utilized to pivot the exercise machine and thus adjust its angle of incline. Various types of adjustment devices are disclosed, including an actuator, ratchet-and-pawl, gears, and cam.

The present invention relates to an exercise method and an exercise device for performing an exercise suitable for thigh and hip muscles like fitness equipment or an exercise bicycle, and more particularly, to an exercise method and an exercise device for strengthening thigh and hip muscles by performing a movement of lowering legs and then moving the legs backward or putting the legs together or apart from a position of pulling the legs toward a chest of the user with an arm disposed between the legs in a sitting or lying position of the user. In addition, the present invention relates to a leg exercise device including a trajectory measuring device of generating motion range information of the exercise device and making the motion range information as data through a motion range measurement sensor attached to a knee and a hip joint of the user seated on the exercise device, smart device and an application of the smart device.

A respiratory device of negative pressure type comprising a shell fastened to the user's chest and/or abdomen with minimal dead space, one or more vacuum and compressed air chambers attached to the shell; vacuum generating and compressed air generating sources connected to the vacuum and compressed air chambers respectively, one or more openings on the shell to allow exchange of the air enclosed between shell and user's body, with the vacuum and compressed air chambers; a valve shuttling between the vacuum and compressed air chambers. By having low dead space, pre-generated vacuum and compressed air close to the user, and the use of fast acting valves in some embodiments, the power requirement, weight, and size are reduced, making the device low cost and portable. In some embodiments, the vacuum and compressed air generating sources can be mounted on the shell itself, making the device ambulatory.

A respiration appliance (10) is configured to entrain the breathing of the subject. The breathing of the subject is entrained to modulate the autonomic nervous system of the subject to decrease sympathetic nerve activity and/or to reduce sympathetic/parasympathetic balance in order to provide relaxation to the subject. The respiration appliance (10) restricts the exhalation of the subject, while permitting substantially unencumbered inhalation, to impact the breathing of the subject in a manner that enhances relaxation.

A force measurement device has a motion dampening device having at least two ends. A first end is releasably engaged to a base frame and a second end is releasably engaged to a moveable member. A load cell is in communication with the motion dampening device. The load cell measures a force imparted by a user and the load cell registers the force to a display which depicts the registered force exerted by the user. A method for measuring the force a user imparts onto an exercise apparatus comprises the user imparting force onto a moveable member. The motion dampening device imparts a force substantially opposite to the user force and a load cell measures the force exerted by the user. The force is transmitted to a display wherein the display depicts the registered force imparted by the user.

A fitness structure includes a bar having a first end portion and a second end portion, a pair of bar support portions provided at each side of the bar and having a plurality of bar support members to place the bar at a plurality of heights, a first load portion and a second load portion spaced apart from the bar to a certain degree and facing each other, a first cable coupled between the first end portion of the bar and the first load portion, a second cable coupled between the second end portion of the bar and the second load portion. Heights of the first load portion and the second load portion vary depending on a height of one of the plurality of bar support members at which the bar is detachably placed.

Provided are a method for strengthening blood vessels with extreme ease and a compression and decompression control system used for performing the method. A compression and decompression control system 1 includes a band adapted to be placed around a particular part of a limb of a user and to apply a compression force to the particular part and a controller for controlling the compression force applied to the particular part with the band. The controller controls the compression force applied with the band in a manner that a compression operation applying a predetermined compression force to the particular part and a decompression operation completely removing the compression force applied to the particular part by the compression operation are alternately repeated. Repetition of the compression operation and the decompression operation allows the vascular endothelial cells of blood vessels of the user to generate a larger amount of nitric oxide, thereby strengthening the blood vessels.

A cardiorespiratory fitness optimizer apparatus includes a mouthpiece and a valve assembly. The mouthpiece includes lower and upper tooth beds and an anterior manifold. The manifold terminates anteriorly at a centralized valve assembly interface and includes at least one air-letting aperture. The valve assembly is matable with the centralized valve assembly interface and includes an adjustable aperture. The user is able to adjust the aperture for increasing and decreasing airflow resistance therethrough for optimizing cardiorespiratory fitness. The cardiorespiratory fitness optimizer apparatus may include at least one sensor for sensing airflow activity within the valve assembly and communicating data relating to the airflow activity to an external device for displaying human readable output relating to the airflow activity upon the external device. The valve assembly is removable from the mouthpiece and replaceable with a plug element for maintaining anterior formations of the mouthpiece when the valve assembly is removed.
