Research On The Design And Implementation Of Sports Fitness Monitoring APP

Through the study of literature and existing relevant APP,the existing main points movement monitoring and fitness sports APP plastic two categories,guidance of monitoring records,social,sports,sports mall,health information,and other functions.Has the immediacy and convenience,scientific and teaching quality,socializing and interest,practicality and flexibility etc,but there is also a data collection co.,LTD.,accuracy is limited,not portable and the shortcomings and so on data processing co.,LTD.In the research and analysis the present situation of the sports fitness APP and its application,as well as the function of sports fitness APP,advantages and disadvantages,on the basis of determining the function and purpose of this APP,design and develop the corresponding APP.The development direction of existing wearable devices not only confined to the movement of data monitoring,more pay attention to the monitoring of physiological data,such as heart rate.And in the monitoring of heart rate,the existing monitoring of heart rate monitoring and simple sense,no heart rate analysis and guidance for sports.Therefore,this topic APP combined with a wearable device,using advanced photoelectric acquisition method,real-time monitoring of movement in the process of heart rate,and can according to different age groups set corresponding movement of the heart rate range,in the process of movement in heart as a safe and effective exercise heart rate,and heart rate of exceeds or is lower than this range for early warning,to ensure safety and effectiveness.In addition to join the regular content,such as movement monitoring(step gauge,distance,speed,calories,etc.),sports load assessment,health management,health information,etc.In determining the project goal,for the purpose to set the structure and framework of the APP,layout and design,identified as user management,sports load monitoring,evaluation and system management of sports load four function modules as the main body of the project,finally,supported by the engineer,complete the APP design and programming work.After complete the APP,the APP interface and function test,to ensure the accuracy and correctness of the interface and function.This article also this project APP step of heart rate and function test,test to select ten subjects,wear sports watches the topic on the run with 3.2 km/h,4.8 km/h,8.1km/h speed walk,walk 5 min each time,using artificial laboratory and polar heart rate table respectively record the actual steps movement,speed,distance and heartrate,etc.,after each experiment,record of data collected watches the movement,as a comparison data.Results: under different speeds,the sports watch APP is used to measure the count and the actual steps have significant correlation between the P.C correlation coefficients were 0.965,0.837,0.964,its measurement precision are91.8%,87.5% and 91.8% respectively,and the actual measuring steps were greater than sports watch measurements,using sports watch measured the P.C of heart rate and the actual heart rate value of 0.846,polar table measured the heart rate and the actual heart rate value P.C is 0.935,and the use of polar measured the heart rate of accuracy is 98.3%,with a high degree of relevance and accuracy,can be a substitute radial measurement method to measure the heart rate in the process of movement.While in motion state,its sports watches under different speed measured the movement of the heart rate and the actual heart rate between the correlation coefficient of 0.939,0.850,0.935,respectively,all have significant correlation,the average accuracy were 90.08%,89.18%,90.74%,and has higher accuracy.In this paper,according to the project demand,research and develop the heart rate monitoring and early warning,such as design,and successfully complete the APP design,and can measure heart steps and movement,to achieve the project goals.
