In the classroom, we often see tha​₽®✘t every student wears s•→ports bracelet on his wri≠ ↔​st. What is the secret weapon? ★© λHow to use it? The field coaches and tλπ​eachers are curious, this iλ↕σσs the first section of the primary s✔ Ω≥chool physical education teacher "σ♠§obstacle running&quo♠↔t; of physical education, a ←☆★teacher, forty student♠♦Ωs, students are wearing colorful→λ sports rings, a look at ♠÷✔the past, intelligent hand ringsλ' have brought different brilliance♠↑₩ to the classroom.

Other careful teachers noticed some↑✔← new changes in the PE class today, in δ addition to a nice "sports ring&$♦✔¥quot; on each student¥↔9;s wrist, and a mobile phone  ∞​was attached to the gym i↓∞✘nstructor's arm; an electro≈®® nic stopwatch with a large sc±<Ω>reen on the edge of the∞  field showed each of them★β. The sports data of students∏♥ are constantly being refreshed. Coac∏Ωhes of physical education c ‍βlasses for this group of s♣•tudents, besides routine↔✘ π demonstration and command≠¥<&, are running, jumpin®γσ₩g and throwing.From time to ≤ σtime, there will be a glimpse of→Ωσ a cell phone and a large scree✘♥n at the edge of the playground®₽. Perhaps a teacher will €​• ask that there is a big sc∞φ‌←reen stopwatch with a ✘★λlarge screen in addition to the♥><‍ students, and there seems to be≤ ¶÷ no difference betwe"Ω↕en the sports class and the p§©®¥ast. The teachers who came to do the'δ€​ lectures were considered to be th±♥e first milestone in th¥™e history of physical educa∞↑tion in Shenzhen.

The secret function of the sports b ÷≤±racelet

The "secret function" of<☆δ the sports ring is that it can m€§§onitor the heart rate of the students ‍↔πin real time. The intel≠φ₹βligent heart rate loop helps the p‍₽hysical education teacher to g£₹→±uide the sports. The heart rate®≥ function of the intellig≤ ent hand loop realizes the clo&♦ se fusion of the informat£αion technology and the physical educat≈♦↔>ion, and the children's w®δarm-up exercise is not enough ♦©in the classroom. Suddenly, the teacherβ₹  in the physical educat≤™ion class walked to the €φlittle student's side, gesture©&₹¶d him to recuperate slightly."The ∑®×warm-up time should be 3 minutes and ←≤40 seconds, but the stu&♣dent's wrist watch vibrate"÷≈s sharply, while the mobile phone in •∑±↔the teacher's arm is ¥ ε‍also synchronizing.&™©♦↕quot; The coach explained, ‍≠☆"it was the sports bracele$φ t that monitored the stude£↓​←nt's heart rate ov♥±♥er the 125 normal frequency of the preγ∞"σset normal heart rate. A∞✔t this time, I had to get him to do sλ↕"ome relaxing exercise, a★→☆nd it was on the basis'₩≥Ω of the signal that th₽←e mini monitor in the sport han∞αd ring on the student's h∞♠✔and sent me a signal.

Just in the classroom, the v‌€olume of the students began ∏♥to increase, and the trβ↓£ainer set the student's he'δ€<art rate to 150 times a  ε♠$minute, when the other sports ring' ≠↓ issued a warning signal, and✔≤ the teacher's mobile phone screen γ♥​showed that the student&#φ<39;s heart rate had reached 173 heartε>φ₩beats per minute. It is necessary to★↔ immediately reduce ₹£the intensity of spo‌≤εβrts in the physical education clas→≠s. The substitute te∞<¥δacher immediately makes a relaxing adj£γ"ustment to the student'♠ π↓s movement. After the teache¥Ω$r uses the sports ring, his phyα‍sical education class is more than befo£®$→re with sports equipment, >♣whistle, and stopwatch. It is the mob✔¶β×ile phone which is connected with th$↓βe backstage data of the sp♣"orts ring.

Heart rate bracelet control of mov↑↕ing hand rings

Before class, in addition t'λo preparing lessons, we  ₽should presuppose preparatioα★n activities, main teachiΩ∞₩↑ng materials, comprehensive♠Ω" activities, relaxation of spor÷₩>ts and heart rate co>↓¥↓ntrol of sports rings. In theλ£≤ course of class, in add ✔∏ition to doing demon♦& strative action, Gu Yonggang also ↑ forms the situation that≥​≤ often looks up on the π ₩≥large screen stopwat∑→ch, which shows the whole claδ<®ss on the large screenβ♦÷∞ stopwatch. The name an₩σ‍d heart rate of the students, e₽®$specially the students who have a freq​ uent surge in heart rate, are almos₹σ€t all the focus of the sports d✔£≤Ωifficult households. It is always hinti≥©ng that the teacher must p∞π♥ay attention to the students' immed₽₹iate physical heart ra↑↑×$te, cooperate with the heart ra≈φte loop and quickly adjust≈✘↓☆ the intensity of the students&®✔#39; movement.

After class, the teachers ✔$use the experience to analyze and s₹₽‌ ummarize whether the load of t&αhe students in this class m€±"♣eets the expected goal. And now t÷ ₹hrough the analysis of the backstage✘✔₩↕ data of the movement h₩σ↕and ring, it is clear that the hear↔→t rate of each student  →λ↔in the class and the intensit‌♦y of the whole class can >☆‍σbe adjusted in the next time. In the♠☆♣ class sports class, other pr✘≥₹imary school PE teachers also ✘↔¶try to introduce the±ε♣‍ heart rate movement Bracelet in theβ¥≥ basketball lesson of physical e§π®→ducation.

He said: compared to th‌↑σ e previous sports, thi§€≥s class used the intelligent heart rate ∏ hand loop to real-time moni↓γβ​tor the real time data of the student★λ''s exercise load, and let thε©e teacher in accordance with the inδ&∞≠telligent heart rate han"★α≈dset and the synchronization ×★φ•of the mobile phone canπ∑ better master every student mo§‍₹vement. And through the contγ←©φrol of the heart rate∑   curve process chart collected by•★ the heart rate loop of the who<ε₽βle class to regulate the app ×Ω≤ropriate exercise load of₽₩ the students, the RESEE intelligent ®φheart rate loop can ma‌←ke the physical education visual  ✘↕visual.After class, the teachin"'✘g and research staff and teachers revie€₹Ω↔wed the data detected by the sports rin≈§ $gs and found that the exercise inte§π₹nsity of the first class in€λ​≥ the first class using the i&≈ntelligent heart rate loop was ↑♠1.78 and the second class was 1.63.₩ ↕ The sports ring data₽±✘ scientifically verifie§£¥↑d that the two classes were of moder✔ ™'ate normal category, the principalβ  of the primary school told the reporΩ¶ter. The sports class in ph✔ ÷✔ysical education begins wit÷γh the practice of the regional informa∞×←×tion project "based onδ£ the physical and mental health o$₽πβf the students in the background ≈≈of physical and mental ∑‍health data." the school♠♠★ has carried out a profound s↔‍tudy on the sports rin•≤g.

In the past, there are ׶‍many deficiencies in t∞•he physical education  ₩εclass. Teachers can not ¥↓'εgrasp the load of the whole class. In ≈≥¶‌particular, they can no$∏∏εt understand the physica$δl condition of each student £≈ in time. The most o€εf them is to stop with stopwat$×‍ ch after a period of ≤>time and let the student★&s check their heart rate. For this reas& ∏≤on, the school has bought and bought '÷≠€500 wearable heart rate sports riβ​✘ngs. I'm going to buy 800 moreε→ teachers and students coverin≥>₹≥g the whole school.The exerci‍©γ×se hand rings are used to monitor₽≠ and warn the students' heart rπ★∞αate and exercise load, because the ea♠≤↓←rly warning of sports rin≤Ωgs includes not only th≠™≠e excessive reminder of ♦₩movement, but also the sm£γ✘<all reminder that the ε©students are not alwΩ"πays in a state of being too mastered in©Ω✘ physical education.

In the background of advance∑✘d cities to vigorously prλ‌omote education info÷σ≤rmation, the school has t≠ "≈he theme of "increasing t≈"he rate of obesity control&qu‌€↔ot;, let students wear®£®≤ sports ring in the course of physicaλφ←l education, take "accompany&q&δ≈uot; data collection, automatic€λ✘ exercise load feedback.
