Description

Strength training belt

The present invention relates to a strength training belt.

Currently, a pressurized muscle strength training method capable of efficiently strengthening muscles by applying a load caused by blood flow inhibition to the muscles has been proposed and put into practical use (for example, see Patent Document 1). In such a strength training method, a strength training belt is used in which a specific portion of a user's limb (arm or leg) is tightened with a belt to apply pressure to the muscle.

In order to carry out the pressurized muscle strength training method using such a muscle strength training belt, it is indispensable to apply an accurate pressing force at a certain accurate position with respect to a specific portion of the muscle to be strengthened. For this reason, in recent years, the pressure applied to the muscles by the belt is obtained as the gas pressure in the pressure-receiving bag, which is transmitted to the pressure-sensitive element by the transmission means, and the transmitted pressure is measured by the pressure-sensitive element. A muscle training belt equipped with a pressure measuring device has been proposed (see Patent Document 2).

However, a muscle strength training belt equipped with a conventional pressure measuring device has a tube (hollow elastic) that includes a pressure receiving bag in which the internal gas pressure changes according to the pressure applied, and a measurement tank in which a pressure sensitive element is accommodated. Since it is necessary to make a communication connection via a tube), the entire device becomes large and bulky, and training may be hindered by the tube.

In the conventional strength training belt, the pressure receiving bag is connected to the measurement tank disposed at the end of the belt through the tube, and the length of the tube is limited. There is a restriction that it must be arranged in the vicinity of the end. When the pressure receiving bag is arranged in the vicinity of the end of the belt in this way, a gap may be formed between the pressure receiving bag and the user's arm (or leg).

When such a configuration is adopted, the pressurizing force applied to the specific portion based on the amount of gas in the gas bag in a state where the loop shape formed by winding the belt-shaped member around the specific portion is maintained by the pressurization measuring device. Can be measured. The pressure measuring device has a pressure-sensitive element arranged on the side of the belt-shaped member facing the muscle, and the pressure is calculated by the calculation unit based on the electric signal output from the pressure-sensitive element. The applied pressure can be accurately measured without the need for a pressure receiving bag or a tube. In addition, a plurality of pressure sensitive elements are provided, and the average value of the applied pressure can be calculated based on a plurality of electric signals output from the plurality of pressure sensitive elements. Compared with the case where the measurement is performed, the possibility of measurement errors can be reduced, and the measurement accuracy of the applied pressure can be improved.
