That is, the conventional muscle exercise mechanism used an elastic body, a hydraulic pressure, a weight stack, etc. as a source of generating resistance, but in the present invention, the load of the generator 10 is a source of resistance, and the user pulls the string 14 to generate the resistance. By measuring the electromotive force, the actual exercise load is measured.

Referring to FIG. 1, the load of the generator 10 is mgh, and when the distance between the generator 10 and the pulley 12 is L, the force F of the user is ma, and the work W by the user becomes FL. .

At this time, the electric energy generated by the generator 10 by the movement is used as a power source of the device according to the invention by charging the storage battery (11). After the maximum strength is measured, the exercise load for the repetition is set (204). In general, it is preferable to set the repetitive exercise load to about 70% of the exercise load by the maximum muscle strength.

Strength training consists of a process of pulling the string (14) and releasing the string (13) while slowly releasing the force after setting the load of the generator (10) as a repetitive exercise load, During strength training, it automatically calculates the actual exercise load, the number of exercise and the calories burned, and displays this information and saves it on a smart card or sends it to the outside through an external interface (serial communication port, TCP / IP, etc.) (205 ~ 207).

In general, strength exercise is performed according to the DeLorme axiom and the overload principle, in order to induce maximum muscle activity, the maximum resistance or the maximum number of repetitions are performed until muscle fatigue occurs. As a scientific technique for measuring muscle fatigue, frequency spectrum analysis (PSA) of EMG signals is used. In particular, intermediate frequency (MDF) is widely used as a parameter for measuring muscle fatigue. According to research using this scientific technique, it is preferable to use strength exercise as a set exercise. A set is a set of the number of repetition of a single exercise. ", And repeating this set several times is a set movement. Therefore, in the strength exercise, it is necessary to count the number of times of exercise. In the embodiment of the present invention, the process of pulling and releasing a line is counted once. At this time, a detailed algorithm for counting once will be described in detail later.

5 is a flowchart illustrating an exercise procedure according to the present invention.

Strength exercise according to the present invention is to set the exercise load after measuring the maximum strength at each exercise, and set exercise with the set exercise load.

As shown in FIG. 6, the procedure for measuring the maximum muscle strength is performed by setting the initial load amount to about 1/2 of the user's weight and then measuring the moving distance, and increasing the load amount again when the instantaneous movement distance is positive (+). Measure the moving distance by (601 ~ 604).

When the movement distance becomes zero or negative at any moment due to such an increase in load, when the timer is driven for more than a predetermined time (e.g., about 0.5 second), the load is recognized as the maximum muscle strength (605 to 608).

After measuring the maximum strength, the exercise load setting step (S2) sets the load of about 70% of the maximum strength as the repetitive exercise load for the repetitive exercise.

And when the user exercises with the set exercise load, the device according to the present invention measures the actual exercise load during the exercise, counts the number of exercise, and calculates calories burned during exercise (S3).

As shown in FIG. 7, the procedure for counting the number of times of exercise checks the load when the user pulls the string (701, 702). Subsequently, if the measured actual load is greater than the repetitive load, the moving speed of the string is sensed when releasing the user string and counted if it is less than the predetermined speed (703 to 707). If the actual load is less than the repetitive load or the speed at the time of release is not less than the predetermined speed, the count is not performed once. In other words, only when the load is greater than the set repetitive load and the speed at which the string is laid is lower than the predetermined repetitive load during the exercise, the motor counts up and inserts the count into the number of exercise. Therefore, if the actual exercise load is less than the repetitive load or if it is released without using force when releasing the line, it is not included in the number of exercise.

The exercise information calculated as described above is transmitted to an external server through the communication unit 318 or stored in the smart card 322 (S4 to S6).

A graph is displayed on the graphic screen, in which the vertical axis represents the load and the horizontal axis represents the time axis. According to the graph of the screen example shown, when the strength exercise by pulling the string, it can be seen that the load increases with time, then falls off at a certain point, then increases to the maximum load and then descends. In this way, the maximum load is measured by the maximum strength.

When the exercise is set after measuring the maximum muscle strength and setting the repetitive exercise load at about 70% of the maximum muscle strength, as shown in FIG. 9, it can be seen that the load is increased or decreased by the repeated exercise.

Referring to FIG. 9, calories burned during exercise and the current set, the number of exercise, and the like are displayed in letters, and the load during exercise is displayed in a graph. If the measured load is lower than the set repetitive load, it is not counted as the number of workouts. In addition, one-time movement refers to the process of pulling a string from the start position to the end position and then slowly releasing the string to return to the starting position. Instead of counting, the alarm or voice message tells you to relax slowly.

In other words, the smart card can be used to manage the rate of change such as maximum strength, exercise, and calorie consumption on a daily, weekly and monthly basis, and the microprocessor can be used to automatically calculate calories during exercise to perform scientific exercise. can do. At this time, the vertical used for calorie calculation according to the present invention is as shown in Equation 1 below.

Calorie consumption at rest in Equation 1 is 3.5Kcal / min / Kg, P [W] = VI when the power consumption is calculated in calories.

On the other hand, exercise equipment can be divided into upper body / lower body / back muscles in general, and when the upper body exercise, there are muscles that develop accordingly, for example, in the case of the power clean the upper body exercise is used to the body (rear ) And shoulder (front), muscles can be divided into quadriceps, gluteus maximus, triceps. In combination with other instruments, the muscle strength of each muscle can be measured using the ratio of muscle strength used by each muscle.

Also, based on this, the general public can be advised to reinforce the lack of strength by strength, and a ranking system can be constructed that can inform the gender, weight, age, and strength ranking based on the data stored in the server. For example, if a 20-year-old male has a power strength of 50Kg and a maximum power of 50Kg, he or she can make an excellent decision according to the average powerline strength of 30Kg, and the ranking is ranked 123 out of 20,000. have. In addition, since the user's strength is automatically stored in the server, you can check the national average of the strength and the average of the user based on this, so that those who are good at giving confidence and those who lack strength can work harder.
