Ukuhlolwa Okusebenzayo Kusetshenziselwa Ukulinganisa VO2 Max
Isivivinyo se-Bruce protocol treadmill sisetshenziselwa ukulinganisa ukuqina okuphelele kwabagijimi bokukhuthazela. Isivivinyo ekuqaleni sakhiwe yisifo senhliziyo uRobert A. Bruce ngo-1963 njengesivivinyo esingenasidingo sokuhlola iziguli ezinesifo senhliziyo esicatshangelwayo. Esimweni somtholampilo, i-protocol yokuhlola isisindo se-Bruce ngezinye izikhathi ibizwa ngokuthi ukuhlolwa kokucindezeleka noma ukuvivinywa kokuvivinya umzimba.
Ukuhlolwa kungasetshenziswa ukulinganisa ukutholwa okukhulu kwe-oksijini ( VO2 max ), okuyisilinganiso somthamo womdlali wokusebenza okuqhubekayo. Ihlanganiswe nokukhuthazela kwe-aerobic.
Ukuhlolwa kwe-VO2 Max
Ukuphakama kwe-oksijini enkulu ( VO2 max ) ngokuqondile kubhekisela emanini amaningi oksijini umuntu angayithatha futhi asebenzise ngesikhathi sokuzivocavoca okukhulu noma okukhulu. Ilinganiselwa njenge-milliliters of oxygen esetshenziswa ngomzuzu owodwa kilogram yesisindo somzimba (ml / kg / min).
Uhlolo lwe-Bruce treadmill luhlolo olungavamile olulinganisa i-VO2 max usebenzisa ifomula kanye nekhono lomdlali wokusebenzisa umsebenzi wokunyathelisa njengoba umsebenzi wanda. Ezinye izindlela zokulinganisa i-VO2 max zinzima kakhulu futhi zidinga ukuqoqwa ngqo nokulinganisa kwevolumu yomoya ne-oksijeni yokuhlushwa kwe-air inhaled and exhaled umdlali osebenzisayo ngenkathi esebenza. Leli qoqo libonisa ukuthi i-oksijeni umgijimi usebenzise kangakanani njengoba egijima.
Ngokusobala, loluhlobo lokuhlolwa okuqondile luzodinga imishini elula kakhulu futhi eyinkimbinkimbi kanye nokuqoqwa kwedatha ukuthi ifomula isekelwe esikhathini esitatimendeni.
Indlela yokulinganisa i-VO2 Max Ukusebenzisa ukuhlolwa kwe-Bruce Treadmill Test
I-Bruce protocol iyinhlolovo enkulu yokuvivinya umzimba lapho umgijimi esebenza ukuqedela ukukhathala njengoba isivinini sokunyathelisa nokunyuka sinyuka njalo njalo imizuzu emithathu.
Ubude besikhathi esitokisini sokuhlola isisindo sokuhlola futhi singasetshenziswa ukulinganisa inani le-VO2 max. Ngesikhathi sokuhlolwa, isilinganiso senhliziyo, ukucindezelwa kwegazi nokulinganisa kokuzikhandla okubonakalayo kuvame ukuqoqwa.
Ukuxwayisa kwe-VO2 Max Treadmill
Ngenxa yokuthi ukuhlolwa kwe-Bruce treadmill kuyinkinga enkulu yokuvivinya umzimba, akuyona into okumelwe yenziwe ngaphandle kwemvume kadokotela kanye nokuqondiswa kochwepheshe. Kumuntu ongafundile noma umdlali onesimo senhliziyo esisezingeni eliphansi, ukusebenzisa umzamo omkhulu kungabangela ukulimala noma izenzakalo zenhliziyo ezingenzeka. Ngesikhathi senza ukuhlolwa kokucindezeleka kokuhamba ngezinyawo, odokotela bazoqapha izimpawu ezibalulekile zesiguli njalo futhi bayeke ukuhlolwa nganoma yisiphi isibonakaliso senkinga.
Kumdlali, ochwepheshe onolwazi kufanele aqaphe izinga lokushaya kwenhliziyo nesigqi phakathi nokuhlolwa. Qinisekisa ukuthi umqeqeshi wakho wokuhlola unolwazi olufanele lomtholampilo futhi uqhube ukuhlolwa okunjalo izikhathi eziningi ngaphambi kokuthi uhambise isitifiketi sokuhlola ukuhlolwa kwakho.
Izigaba zokuhlola zeBruce Treadmill
Isigaba 1: 1.7 mph ebangeni leshumi lamaphesenti
Isigaba sesi-2: 2.5 mph ebangeni le-12%
Isiteji sesi-3: 3.4 mph ngamaphesenti angu-14 ebangeni
Isigaba sesi-4: 4.2 mph ebangeni lamaphesenti angu-16
Isigaba sesi-5: 5.0 mph ebangeni leshumi lama-18
Isigaba 6: 5.5 mph ngamabhesenti angu-20 ebangeni
Isigaba 7: 6.0 mph ngamabhesenti angu-22 ebangeni
Isigaba 8: 6.5 mph ebangeni lamaphesenti angu-24
Isigaba 9: 7.0 mph ebangeni lama-26%
Iprotocol ye-Bruce Protocol For Estimating VO2 Max
Lezi amafomu asetshenzisiwe:
- Kubantu VO2 max = 14.8 - (1.379 x T) + (0.451 x T²) - (0.012 x T³)
- Kwabesifazane VO2 max = 4.38 x T - 3.9
- T = Isikhathi esiphelele esitokisini sokulinganisa esilinganiswa njengengxenyana yeminithi (isikhathi sokuhlola semaminithi angu-30 imizuzwana 30 izobhalwa njengo-T = 9.5).
