In the classroom, we often$‌  see that every student wears sportβ​≈≥s bracelet on his wrist. What is the sec €÷ret weapon? How to use it? The fieδ×​ld coaches and teachers are curious, this ₽≥↔is the first section of the primar™£Ω©y school physical education teacher "obsta₽÷​cle running" of phy↑≈sical education, a teacher, forty☆♦ students, students are wearing colorful φ≥< sports rings, a look at the past§✔, intelligent hand rings have bro★δ∞>ught different brilliance to the classroom.

Other careful teachers noticed some n↑×ε☆ew changes in the PE class today, in additio £"®n to a nice "sports ring" on each stud≥↕₽Ωent's wrist, and a mobile phone was attached ¶∏to the gym instructor's ar✘εεm; an electronic stopwatch with a large screen on£₹γ← the edge of the field showed each of t€‍∞★hem. The sports data of students are consta♣¥↓ntly being refreshed. Coaches of " physical education classes for this group of s≈✘tudents, besides routine demonstratioα&∞​n and command, are running, jumping §σ§φand throwing.From time to time, there will be a g≤$limpse of a cell phone and a large screen at th₽✔e edge of the playground. Perhaps a teacher willλ  ask that there is a big sc♥π∏αreen stopwatch with a ✔≠¶λlarge screen in addition to the students, and thλ<♥★ere seems to be no difference between σ≤↔the sports class and t✘™βhe past. The teachers who came to do th♠₩&e lectures were considered to be t✔‍ε₽he first milestone in the history≠♣≈¶ of physical education in Shenzhen.

The secret function of the spo₽₹rts bracelet

The "secret func•₹βtion" of the sp ↕∏¥orts ring is that it∞ε can monitor the heart rate of the students®★δ in real time. The intelli Ω¥gent heart rate loop helps the physi☆Ωcal education teacher to guide the ‌​sports. The heart rate function of the inσσ™>telligent hand loop realizes the close fusion≥βΩ of the information technology aβ♣₩nd the physical education, and the children'♠≤→↕s warm-up exercise is not enough in t€>•he classroom. Suddenly, the teacher in the ph£•≈"ysical education class walked to the littl↔♠♠e student's side, gesture>₹d him to recuperate slightly."The w€×✘σarm-up time should be 3 mi★←™nutes and 40 seconds, but the student's>‌× wrist watch vibrates sharply, whiΩ<le the mobile phone in the teac∞¥her's arm is also synchron ‌÷&izing." The coach explained, &qu÷ &σot;it was the sports§¥↑÷ bracelet that monitored the stud₹​©ent's heart rate over the 125 ≠× normal frequency of the pr♦≈eset normal heart rate. A®•↑☆t this time, I had to&​$₩ get him to do some r±→♠elaxing exercise, and it was on the☆α♦ basis of the signal that the mini monitor in the←β sport hand ring on the student's hand sent∞£↓÷ me a signal.

Just in the classroom, the volume o>λ♥f the students began to increase, and the₽∞∑™ trainer set the student's heart rate to 150±✘"φ times a minute, when the ot→'λ her sports ring issu∑★ed a warning signal, and the teacher's mobile£↑ phone screen showed that the student&¶≥φ₹#39;s heart rate had reached 173 heartbeats λ↕≤¶per minute. It is necessary to i§★‌<mmediately reduce the intensity of sports in th"☆φ•e physical education class. The substitut>δ₽e teacher immediately makes a relaxing adjus¥ ☆≤tment to the student&#★"↕39;s movement. After☆☆∑ the teacher uses the sports ring, his¶✘↓← physical education class is more than before wit↓∑h sports equipment, whistle, and stopwat♥πch. It is the mobile phone which'∞♥ is connected with the backstage data of the spor♣≈ts ring.

Heart rate bracelet c₩♥ ontrol of moving hand rings

Before class, in addition to preparing le☆→ssons, we should presu✘✔εppose preparation activiti ∞¥φes, main teaching mat©↑¥erials, comprehensive activities, relaxation of ♣♠₩↔sports and heart rate controσ‍ &l of sports rings. In the course of class, in aφ↔©£ddition to doing demonstrative action, Gu× λε Yonggang also forms the si₽§≈♦tuation that often looks up on the large scr€✘een stopwatch, which shows the whole class>♥ ₽ on the large screen stopwatch.>≠ The name and heart rate of the students, especia‌←≈¶lly the students who have a frequent surge in hea₹✔rt rate, are almost all the focus of the sport&•α±s difficult households. It $φis always hinting that the teache↔& ★r must pay attention to the students&#§‌39; immediate physical heart ra¶‌εte, cooperate with the heart rate lσ↓¥&oop and quickly adjust the intensity o÷♦<☆f the students' movement.

After class, the teachers us§ δ e the experience to >‌analyze and summarize whether t≥Ω>he load of the student≤∏βs in this class meets the expectε×ed goal. And now through the analyσφ♦ sis of the backstage♥δ data of the movement hand ring, it is clear §§↑that the heart rate of each student in the classα÷ and the intensity of the whole>π§ class can be adjusted in the next ti♥≠± me. In the class sports class, ot<αher primary school PE teachers also try to ₹•©φintroduce the heart rate mov→εement Bracelet in th☆¥✔↑e basketball lesson of physical eβ₹<±ducation.

Experience + exercise heart rate bracele§ t to make students exercise more efε$δ¥ficiently.

He said: compared to the previ∑©→↑ous sports, this class₽> used the intelligent h☆↑←πeart rate hand loop to real-time monitor t£↑↔€he real time data of the student's★♠←δ exercise load, and let the teache÷​€≠r in accordance with the intelligent heart rate h"¥andset and the synchron‌σization of the mobil∞£e phone can better master ☆♠&every student movement. And through βε<the control of the heart ra ↔>€te curve process chart collected by the he∑Ω∑art rate loop of the whole class ∑γ₽to regulate the appropriate exercise lo€φad of the students, the RESEE¶≥β intelligent heart rate loop can make the physica≤Ω★✔l education visual visual.After class,♣λ ¶ the teaching and research staff ♥©and teachers reviewed the data de↕λλtected by the sports rings and found that the ex ∏☆ercise intensity of the♠αγ first class in the first class using th♠>≈e intelligent heart rate l↔♥♣γoop was 1.78 and the second class was 1.≥​  63. The sports ring data scien✔♠≠δtifically verified that the two classes were of ≠$moderate normal category, thε ε​e principal of the pr≤≈&imary school told the reporter. Thγ✘αφe sports class in phy∑↕sical education begins with t✘&•σhe practice of the regional information proj✘&ect "based on the physical and mental health★× of the students in the background of phβ♣ysical and mental health data.&q&γα uot; the school has carried out a profound stu§>ε☆dy on the sports ring. It also requires the ma☆↑♠​nufacturers of intelligent heart rate bracelet←× to finish the function of →≠the hand loop and th♥‌ e accuracy of the data.

In the past, there are σσmany deficiencies in the physical educat&↕™ion class. Teachers can not δ×♥™grasp the load of the who​≈le class. In particular, they can≈£♦ not understand the physical condi™ •±tion of each student in time. The most of them Ω​πεis to stop with stopwatch after a period of time ♣¥and let the students check ®$their heart rate. For this reason, the schoΩ↑£ol has bought and bought 500 wearable heart αλεrate sports rings. I'γφ€;m going to buy 800 more teachers and students cπ≈↕overing the whole school.The ex★••£ercise hand rings are used$§ § to monitor and warn the studen &ts' heart rate and exercise load, becauseΩ¥> the early warning of spor©©ts rings includes not onl§εy the excessive reminder of movement, but also th×↕₽☆e small reminder that the students are not alway↔÷♦s in a state of being too mastered in ₩↑∑physical education.

In the background of advan→€®♦ced cities to vigorously promote education infor↓•mation, the school has the theme of "©♦€'increasing the rate of obe​δsity control", let students ™ ± wear sports ring in γ↑π±the course of physical education, t♣¥ake "accompany" data coll✘✘≈ection, automatic exercise load feedδ δ∏back. On the one hand, through the≥•©£ hand loop monitoring the students' hear​∞₹t rate, movement intensity, and the number of ♥'₩<steps, through the handset of t‌&he teacher's mobi∑λ₽₹le phone and the real-time  ₹<↔heart rate hand loop data switch on th  ÷e large screen, it presents the effectiveα≤ data of the classroom movement intensit§∞♥☆y; on the other hand, it can intγ£ervene the process of student movement in real ∑×↕time.Before class, the warning value of heart ra↔♦∑te is set on the sports ring before the•¥ class, so as to monitor t±✘he data of the hand loop ↔ ←in the classroom, warn the warning•₽ , and pay attention to the real tπε≠ime, and the use of  <the sports ring not on ">ly makes the students&✔↓#39; sports load in the physical educa€↔≈∞tion class visual monitoring, the heart rate datα↔a accumulation, but also provides the technic©≤al path through the sports ring spor ≥ts class. Students' physique is suppor∑¶ ♦ted by data. The sports brac₹☆elet can lay the data basis for sp•≠↑orts load for the overall development of→★λ students' physique.
