Description

Field of technology

The utility model relates to sports and physical education activities, namely to methods of quantitative measurement of external resistance of the biceps muscles of two human arms in order to assess muscle strength and strength endurance in various living conditions and professional activities. The device can be used in testing and training on various stands and simulators.

State of the art

A device is known for recording the level of abdominal muscle tension, which is part of a system for automated assessment of a pilot's condition under conditions of exposure to piloting overloads, in a method for assessing the operator's condition under the effect of head-pelvis overloads (patent RU 2111698 IPC A61B 5/00, published on 27.05.1998), wherein the magnitude and duration of the overload action along the Px and Py axes connected to the aircraft cabin, the force of foot pressure on the pedals, the level of abdominal muscle tension, the pressure in the chambers of the anti-overload suit are continuously measured, the total protective effect from the use of anti-overload protection means and techniques is determined based on the measured values, then the reduced overload is determined as the difference between the Py value and the total protective effect.

The disadvantage of the known device is the low accuracy of measuring the level of tension of the biceps muscles of both arms using a strain gauge before, during and after training.

The closest known device for recording the level of tension of the abdominal muscles in humans (patent RU 2220657 IPC A61B 5/22, published: 10.01.2004 Bulletin No. 1) consists of a sensor that responds to the force of tension of the abdominal muscles, wherein the sensor is made in the form of a dynamometer equipped with an inextensible belt with a buckle for fixing the belt on the waist of a person, wherein the level of tension of the abdominal muscles is determined by measuring the tension force of the belt, which makes it possible to use the device in various conditions, and the level of muscle tension can be determined directly by visual reading on the dynamometer scale or by recording an electrical signal generated by the built-in rheostat sensor of the dynamometer, on an external recording device.

The disadvantage of the closest device is the low accuracy of measuring the level of tension of the biceps muscles of both arms using a strain gauge before, during and after training.

Disclosure of a utility model

The technical result is to increase the accuracy of measuring the level of tension of the biceps muscles of both arms using a strain gauge before, during and after training.

The technical result is achieved in a device for recording the level of external resistance of the biceps muscles of two human arms, consisting of a sensor that responds to the force of external resistance of the biceps muscles, wherein the sensor is made in the form of a strain gauge equipped with a non-stretchable rod, with the ability to adjust the position of recording the level of external resistance of the muscles, in the form of a chain with snap hooks and nuts, in the position of the user's height with a handle for pulling with two hands, standing on a support platform that serves as a base for attaching the strain gauge with a non-stretchable rod, and with the ability to determine the level of external resistance of the biceps muscles of two arms, in the form of the tension force of the rod, by direct visual reading on the strain gauge scale.

The distinctive features are

the sensor is made in the form of a strain gauge equipped with a non-stretchable rod, with the ability to adjust the position of recording the level of external muscle resistance, in the form of a chain with snap hooks and nuts, in the position of the user's height with a handle for pulling with both hands, standing on a support platform that serves as the base for attaching the strain gauge with a non-stretchable rod, such a design increases the accuracy of measuring the level of tension in the biceps muscles of both arms using a strain gauge before, during and after training;

with the ability to determine the level of external resistance of the biceps muscles of both arms, in the form of the tension force of the pull rod, by direct visual reading on the scale of the strain gauge, this increases the accuracy of measuring the level of tension of the biceps muscles of both arms using a strain gauge before, during and after training.

Comparison of the claimed solution with analogues and the prototype did not reveal any features that distinguish the claimed solution, which allows us to conclude that it meets the “novelty” criterion.

Brief description of the figure

Fig. 1 shows a profile view of the device for recording the level of external resistance of the biceps muscles of two human arms,

where 1 is the base for attaching the strain gauge; 2 is an eye bolt with a fastening to the base; 3 is a snap hook with a nut used to securely connect the eye bolt and the chain; 4 is a chain; 5 is a snap hook with a nut used to securely connect the chain and the strain gauge; 6 is a strain gauge; 7 is a snap hook with a nut used to connect the strain gauge to the handle; 8 is a pull handle.

Implementation of a utility model

The device for recording the level of external resistance of the biceps muscles of two human arms is mounted using the purchased components of the structure. The base 1 for fastening the strain gauge is made of 12 mm plywood, 300×600 mm in size. In the geometric center of the base 1, a rapper is fixed with four countersunk bolts, into which an eye bolt 2 is screwed, connected by a snap hook with a nut 3 with a chain 4 in the lower position of the traction. In the upper position of the traction, the chain 4 is connected by a snap hook with a nut 5 with the strain gauge 6, with its lower hole for fastening, the strain gauge 6 is connected by an upper fastening with a snap hook 7 with a nut, with the traction handle 8.

An example of using a device for recording the level of external resistance of the biceps muscles of two human arms.

The user stands with his feet on the base 1 with its center located between the legs. Adjusts the length of the user's traction, in the form of connected elements of the device in the sequence: base 1, eyebolt 2 with fastening in the rapper, snap hook with nut 3, chain 4, snap hook with nut 5, strain gauge 6, snap hook with nut 7 and traction handle 8, allowing to hold the traction handle 8 in the hands of both hands with bent arms in the forearms at an angle of 90° to the user's body. In this case, the sensor is made in the form of strain gauge 6, equipped with an inextensible traction, with the ability to adjust the position of recording the level of external muscle resistance, in the form of chain 4 with snap hooks with nuts 3, 5 and 7, in the position of the user's height with the handle 8 for traction, standing on the support platform 1, serving as the base for fastening the traction and strain gauge 6 with an inextensible traction. In this case, the tension force of the pull rod determines the level of external resistance of the biceps muscles, with the possibility of determining the level of external resistance of the biceps muscles of both arms, in the form of the tension force of the pull rod, by direct visual reading on the scale of the tensiometer 6. This procedure is performed simultaneously with a duration of 2-3 s.

Thus, in sports and physical education activities, the use of a device for recording the level of external resistance of the biceps muscles of two human arms increases the accuracy of measuring the level of tension of the biceps muscles using a strain gauge before, during and after training.
