Fitness guidance method and system

Abstract

The invention discloses a fitness guidance method and system. The method comprises the following steps: obtaining fitness history log record data; preprocessing the fitness history log record data, extracting feature data from the processed data, and establishing a sample set; training a limit gradient boosting decision tree by adopting the sample set, and conducting a fitness guidance model; importing to-be-tested information of a target user into the fitness guidance model, and outputting fitness guidance information corresponding to the target user, wherein the fitness guidance information is a strength level set by fitness equipment in each time period so as to enable a heart rate of an exerciser to reach an adjustment value of a corresponding preset heart rate range. According to the method and the system, bodybuilders can adjust and control their heart rates to reach a corresponding preset heart rate range according to different time periods of a bodybuilding scheme plan, so that a a good exercise effect is obtained.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a fitness guidance method and system. Background technique [0002] In the field of fitness, monitoring heart rate is a recognized means to understand and measure the exercise level of bodybuilders. Now some wearable devices (such as smart bracelets, watches, and some special wearable devices that monitor the heart rate and analyze the wearer's heart rhythm to achieve early warning of abnormal heart rhythm) Wearable equipment, fitness equipment such as treadmills have been equipped with heart rate detection sensor equipment, there are commonly used hand-held type, relatively rare ear clip type and chest strap type) can monitor heart rate, very used in fitness occasions, when not in use The situation of professional medical equipment If you want to get a preliminary understanding of a person's physical state, heart rate monitoring is an effective and generally practical way. ...

Problems solved by technology

[0012] 1. The difficulty of manually adjusting and setting up fitness equipment by the fitness coach or the bodybuilder at the designated time point according to the recommendations of the fixed and rigid commonly used but unscientific fitness program that may not conform to the actual physical condition of the individual, this kind of stereotyped for everyone The method of using a fixed difficulty setting process obviously lacks scientific basis. The fitness effect may vary greatly due to the great difference in the physical fitness of different people, and it is necessary to manually adjust the difficulty of the fitness equipment at different time points. There is no Realize automation, let alone intelligence

[0013] 2. According to the commonly used fitness plan, the automatic change process of the sequence difficulty in the fitness process is fixedly set on the fitness equipment. This solution only realizes the automatic adjustment of the difficulty of the equipment at certain points in time, but it obviously does not solve the basis for setting Difficulty level and duration to meet scientific fitness goals and personalize fitness issues

This solution is obviously equivalent to the great progress of the first two. It not only realizes automatic adjustment, but also considers the change of heart rate with fitness difficulty and time, and tries to calculate the next time according to the current heart rate and fitness difficulty level at a certain point in time. Adjust the level of difficulty to increase or decrease the heart rate of the bodybuilder to the target range. This scheme is obviously advanced to a certain extent, but its essence is still an empirical closed-loop control, because its adjustment algorithm is still artificial. The logical judgment of the design is not based on the potential law that the bodybuilder's own heart rate changes with the difficulty. Therefore, although the actual effect of this scheme has greatly improved compared with the previous two schemes, it is still inaccurate most of the time. That is to say, after adjusting the fitness difficulty according to its algorithm, the heart rate of fitness often does not increase or decrease to the expected and ideal heart rate range, so there is still a distance from the goal of scientific fitness. This is also a large foreign company that entrusted us to do research and development. Realistic Difficulties Faced by Fitness Chain Enterprises

[0015] To sum up, when the current fitness chain enterprises make a plan for exercisers who come to the store to purchase exercisers who have specialized coaching services, they either use treadmills and other fitness equipment for exercise, or they do not follow certain scientific and reasonable rules. Instruct the bodybuilders to set the difficulty level of the equipment (or intensity level, Intensity Level) and the setting of the exercise time for each difficulty level, and do not formulate personalized fitness intensity and time setting plans according to the different physical conditions of the bodybuilders. Or although a fitness program has been formulated according to the fitness intensity effect interval and a certain algorithm is designed to automatically adjust the difficulty of fitness equipment over time according to the fitness program, these algorithms are based on artificially set logical judgments based on empirical formulas, not based on It is designed by the bodybuilder's own physical fitness and exercise history, so there is a big gap between the accuracy of controlling the bodybuilder's heart rate changes during the fitness process and the rigor of the difficulty setting of the fitness equipment from scientific and reasonable fitness
