Description

Smart exercise device capable of real-time muscle strength measurement

The present invention relates to a smart exercise device capable of measuring muscle strength in real time, and more particularly, it is interesting because it is possible to perform various exercises that can be performed in a fitness center, etc. in one device, and also measures and displays the user's muscle strength in real time during exercise. You can perform gradual overload exercise with a load that suits you with the It relates to a smart exercise device capable of real-time muscle strength measurement that guides users to exercise in an optimal environment by recommending an elastic band with the most appropriate elasticity according to the user's muscle strength even when exercising in various sports.

In general, strength training is performed using exercise equipment that imparts a sense of weight, such as weight equipment or elastic bands, but this is a measurement that measures the user's muscle strength in real time during exercise, only repeatedly performing simple strength exercises against the given weight. Since there is no function, there is a problem in that systematic exercise management is not performed at all, in which exercise is customized according to the user's muscle strength, and which muscle has grown how much, and muscle strength data is managed by part and day after exercise.

In addition, strength training develops muscles according to the principle of gradual overload, which means that you slowly increase the weight you handle each time. However, since the existing weight equipment determines the weight by the block fitted to the equipment, it is possible to increase the weight in units of 2.5 kg, 5 kg, and 10 kg, which are the weight of the unit block. Therefore, it is difficult to gradually overload such as 20kg, 20.1kg, 20.3kg, 20.5kg, and there is a disadvantage that the weight cannot be increased from 20kg to 22.5kg immediately. In addition, the existing exercise equipment has problems in that cost and installation area are high, such as having to separately provide an expensive dedicated machine for each exercise item.

In addition, a relatively inexpensive elastic band made of rubber material was used at home. Depending on the type of exercise, in some cases, the band is held short and exercised while sitting down, and in some cases, the band is long. In some cases, you may need to hold the exercise and raise your arms above your shoulders. However, the conventional elastic band is made of a rubber material in its entire length, and when the length of the band changes, the pulling force also changes. For example, if you hold the elastic band short, you have to pull it with a lot of force to get it to the same length, whereas if you hold it long, it can be stretched to the same length with a little force. There is a problem that cannot be done.

In addition, as for the existing elastic bands, several bands with different elasticity were provided by color-coded yellow, red, blue, purple, black, etc., and a plurality of bands were used in combination according to their own strength for each exercise. However, even for the same person, it is not difficult to figure out which band to use and how many combinations to use because the strength is different for each of the over 30 types of exercise. Therefore, most of the cases complain that the exercise is not possible due to the use of a band combination that is too hard or too weak without using a band suitable for each exercise.

In addition, as in (a) to (c) of FIG. 2, the present invention arbitrarily selects the length of the strap 25 according to the exercise posture, such as holding the strap 25 short and exercising while holding the strap 25 according to the type of exercise. Even if adjusted, the elastic portion 26 always maintains a constant length and elasticity, so that a strength exercise can be performed with a constant exercise load. Or, because the exercise load imbalance problem does not occur, such as not being stretched well, the planned exercise can be performed with uniform resistance. For reference, since the length of the user's feet in a bent state or the length in which the arms are stretched in a folded state are almost the same, if the elasticity is the same, it is possible to exercise with a constant exercise load.

In addition, the elastic portion 26 of the strap 25 is provided with a plurality of elastic bands 28 having different elastic forces, as shown in FIG. detachably connected to the However, at this time, since the user is exercising through different muscles for each exercise, a large muscle such as the pectoralis major muscle should use the elastic band 28 with high elasticity, and a relatively small muscle such as the deltoid muscle should use the elastic band 28 with low elasticity. do. However, it is not difficult for a beginner to grasp the elastic band 28 suitable for him for each exercise as described above.

Therefore, the present invention calculates the elastic band 28 of the most suitable elastic force (or the closest elastic force) to the corresponding muscle based on the muscle strength of the corresponding muscle sensed by the first sensor 12, and displays means 40 It is recommended to the user through the band recommendation unit 42 of Therefore, since the user only needs to connect the recommended elastic band 28 to the strap 25, even beginners can select and use the elastic band 28 that suits them very easily. For example, if the elastic band 28 is marked with yellow, red, blue, purple, and black for 1kg, 3kg, 5kg, 10kg, and 20kg, respectively, when the user measures the muscle strength of the deltoid, 8.3kg is If it comes out, the closest elastic band 28 is a recommended way to connect one blue and one red to the strap 25 .

In addition, the present invention is provided with an exercise result display unit 43 showing the degree of muscle strength increase and decrease for each part on the human body structure diagram after the exercise is finished, so that the user can very easily grasp how much muscle strength has increased in which part at a glance. . Moreover, the display means 40 is further provided with an exercise item recommendation unit 45 that recommends focusing on a region with a low muscle strength increase rate or a region requiring exercise based on the exercise result, so that even non-specialists can exercise systematically. There are possible advantages.

In addition, even if the same exercise load is applied to the strap 25 of the present invention when exercising with the same length, if you slightly increase the pulling length of the strap 25 today than yesterday, the increased load is applied, so the gradual overload movement is very It is done easily.

Accordingly, the bench 50 has the function of allowing the user to exercise while lying down and the function of allowing the support 10 to be firmly fixed by being pressed by the weight of the person lying down.

In addition, in the second embodiment of the present invention, as shown in FIGS. 10 and 11 , a sensor bundle (A) consisting of a combination of a length adjusting means 30 , the first sensor 12 , and a rotating support 15 is provided. Only one is provided, and the elastic band 28 is divided into left and right sides at the end of the length adjustment unit 27 and is connected to both ends of a pair of handles 29 or barbell bars to enable movement with both hands. Of course, when exercising with one hand, it is of course possible to exercise with one hand by connecting the elastic band 26 to the end of the length adjustment unit 27 only to one side. At this time, a screw shaft 17b and a nut 17c are provided at the lower end of the sensor bundle A, and can be used by connecting to a separate footrest or door frame.

In addition, in the third embodiment of the present invention, as shown in FIG. 12 , both strength exercise data and aerobic exercise data can be measured using a single device, so that there is a complementary synergistic effect. That is, since both the muscle strength exercise and the aerobic exercise can be measured through one main body and one electronic circuit 13, the unit cost can be greatly reduced compared to the function, and the development and manufacturing process can be greatly simplified. In addition, people who do aerobic exercise always feel the need for strength training, and people who exercise strength always feel the need for aerobic exercise. . In other words, there is no need for a separate exercise space, and the synergistic effect is great, such as performing aerobic exercise and strength exercise by appropriately mixing.
