Method for automatically controlling speed and gradient of electric treadmill according to heart rate of body-builder

Abstract

The invention relates to a method for automatically controlling speed and gradient of an electric treadmill according to the heart rate of a body-builder, which comprises the following steps of: setting ten kinds operating time in five grades; confirming a five-grade Q value; inputting age and sex; calculating a target heart rate B value by a CPU; starting the whole treadmill and improving speed by 0.5km / h per minute when the heart rate does not reach the B value; automatically shutting down under the condition that the heart rate exceeds the B value when the speed is 1 km / h, and the gradient is 0 percent; improving the gradient by 0.5 percent per minute under the condition that the heart rate does not reach the B value yet when the speed is increased to 6km / h, improving the speed according to the grade difference when the gradient reaches 15 percent and the heart rate does not reach the B value yet, keeping unchanged under the condition that the heart rate does not reach the B value yet when the speed is 7km / h, automatically reducing the speed and shutting down when reaching the total running time, and the like. The invention can automatically control and adjust the speed and the gradient of the treadmill and the running time at each time interval intelligently according to the heart rate, lead the body-builder to run according to a reasonable program meeting the self physical ability, meet the running requirements of different body-builders or the same body-builder in different physical states and achieves the aim of scientific exercise.

Description

technical field [0001] The invention belongs to the technical field of electric treadmills, and more specifically relates to the design and innovation of a method for automatically controlling the speed and gradient of an electric treadmill according to the heart rate of a bodybuilder. Background technique [0002] As aerobic exercise equipment, electric treadmills are more and more popular among the masses. [0003] The control procedure of the traditional electric treadmill can be summarized into two kinds. One is fixed control mode and the other is user control mode. [0004] In the fixed control mode, the control program of the electric treadmill is fixed. That is to say, in addition to the special instructions issued by the bodybuilder such as "starting up" and "emergency stop", the electric treadmill will automatically run according to a fixed program, such as several fixed speeds, slopes and time periods, while The physical fitness, physiological state and enduranc...

Problems solved by technology

However, due to the limited exercise experience of the bodybuilders, limited understanding of the performance of the treadmill, and unreasonable grasp of their own physical fitness, the settings are often difficult to meet the scientific exercise requirements of their own physical fitness.

[0007] In fact, under the above two control modes, it is difficult for body builders to achieve a scientific and reasonable exercise purpose that is truly in line with their own physical fitness.
