Ngenkathi i-classicibhande lesifuba lokushaya kwenhliziyoihlala inketho ethandwayo, abaqaphi bezinga lokushaya kwenhliziyo optical sebeqalile ukuthola ukudonsa, kokubili phansiamawashi ahlakaniphilefuthiabalandeleli bokufanelekaesihlakaleni, nanjengezinto ezizimele engalweni.Ake sibhale okuhle nokubi kweziqapha ukushaya kwenhliziyo yesandla.
Izinzuzo
Kanye nokwanda kwama-trackers asekelwe esihlakaleni afana ne-Apple Watch, Fitbits, ne-Wahoo ELEMNT Rival, sibona nokwamukelwa kabanzi kwamamonitha okushaya kwenhliziyo. Isilinganiso senhliziyo esibonakalayo sisetshenziswe kuzilungiselelo zezokwelapha iminyaka eminingi:iziqeshana zeminwe zisetshenziselwa ukukala izinga lokushaya kwenhliziyousebenzisa i-photoplethysmography (PPG). Ngokukhanyisa ukukhanya okuphansi esikhunjeni sakho, izinzwa zingakwazi ukufunda ukushintshashintsha kokugeleza kwegazi ngaphansi kwesikhumba futhi zithole ukushaya kwenhliziyo, kanye namamethrikhi ayinkimbinkimbi anjengomoya-mpilo wegazi, acutshungulwe ngesikhathi sokukhuphuka kwe-COVID-19.
Njengoba cishe ugqoke iwashi noma i-tracker yokufaneleka, kunengqondo ukuthinta inzwa yokushaya kwenhliziyo ngaphansi kwekesi ngoba izothinta isikhumba sakho. Lokhu kuvumela idivayisi ukuthi ifunde ukushaya kwenhliziyo yakho (noma, kwezinye izimo, ikudlulisele kuyunithi yekhanda lakho) ngenkathi ushayela, futhi kuhlinzeka ngezibalo ezengeziwe zezempilo nezokuqina ezifana nezinga lokushaya kwenhliziyo ephumula, ukuhluka kwenhliziyo, nokulala. ukuhlaziywa. — kuye ngocingo.
Kunenombolo ye-armbandi yezinga lokushaya kwenhliziyo esebenzayo e-CHILEAF, njengei-CL830 Step Countingr Armband Heart Rate Monitor,I-Swimming Heart Rate Monitor XZ831futhiI-CL837 Blood Oxygen Real-Heart Rate Monitorenikeza ukusebenza okufanayo njengebhande lesifuba kodwa kusukela esihlakaleni, ingalo yangaphambili noma ama-biceps.
Ububi
Izinzwa ze-Optical heart rate nazo zinezithiyo eziningi, ikakhulukazi uma kuziwa ekunembeni. Kuneziqondiso zokugqoka isitayela (ukulingana okuqinile, ngaphezu kwesihlakala) futhi ukunemba kuncike esikhumbeni, izinwele, ama-moles nama-freckles. Ngenxa yalezi zimo, abantu ababili abagqoke imodeli yewashi efanayo noma inzwa yokushaya kwenhliziyo bangase babe nokunemba okuhlukile. Ngokufanayo, akukho ukushoda kokuhlolwa embonini yebhayisikili/yokufaneleka kanye namajenali abuyekezwe ngontanga abonisa ukuthi ukunemba kwawo kungahluka ukusuka ku-+/- 1% kuye ku-+/- izinga lephutha. Isayensi Yezemidlalo ngo-2019 Ucwaningo lubonise amaphesenti angu-13.5.
Umthombo walokhu kuchezuka kuhlobene kakhulu nokuthi ukushaya kwenhliziyo kufundwa kanjani futhi kuphi. Ukushaya kwenhliziyo okubonakalayo kudinga inzwa ukuthi ihlale inamathele esikhumbeni ukuze igcine ukunemba kwayo. Uma uqala ukuwanyakazisa - njengalapho ugibele ibhayisikili - ngisho noma iwashi noma inzwa iqinisiwe, zisanyakaza kancane, okuphinde kwenze umsebenzi wazo ube nzima kakhulu. Lokhu kusekelwa ucwaningo lwango-2018 olushicilelwe kujenali ye-Cardiovascular Diagnosis and Therapy, ehlole okuhlukile kwenzwa yokushaya kwenhliziyo optical kubagijimi abagijima ku-treadmill ngesikhathi sokuhlolwa. Njengoba ukuqina kokujima kwakho kukhula, ukunemba kwenzwa yesilinganiso senhliziyo yokubona kuncipha.
Kube sekusetshenziswa izinzwa nama-algorithms ahlukahlukene. Abanye basebenzisa ama-LED amathathu, abanye basebenzisa amabili, abanye basebenzisa eluhlaza kuphela kanti abanye basasebenzisa ama-LED anemibala emithathu okusho ukuthi amanye azonemba kakhulu kunamanye. Okuyikhona kunzima ukukusho.
Ngokuvamile, ezivivinyweni esizenzile, izinzwa zokushaya kwenhliziyo okubonakalayo zisantula ngokuya ngokunemba, kodwa zibonakala zinikeza inkomba enhle yokushaya kwenhliziyo yakho ngenkathi usasebenza - into efana neZwift. uhlanga - Ngokuvamile, isilinganiso sokushaya kwenhliziyo yakho, izinga eliphezulu lokushaya kwenhliziyo, nezinga lokushaya kwenhliziyo eliphansi kuzofanelana nebhande lesifuba.
Kungakhathaliseki ukuthi uqeqeshwa ngokusekelwe ekushayeni kwenhliziyo yakho kuphela, noma ukulandelela noma yiluphi uhlobo lwenkinga yenhliziyo (hlola nodokotela wakho mayelana nokugcina kuqala), ibhande lesifuba liyindlela yokuhamba ukuze uthole ukunemba kwephuzu kuya kwephuzu. Uma ungagcini nje ngokuqeqeshwa okusekelwe ekushayeni kwenhliziyo yakho, kodwa ufuna nje amathrendi, i-optical rate monitor izokwanela.
