Ukugibela i-Electric Bike Thuthukisa Ukusebenza Kwenhliziyo Kwabantu Abadala
Ucwaningo oluningi lomtholampilo lubonise ukuthi ukugibela ibhayisikili likagesi izikhathi ezimbalwa ngeviki kungathuthukisa ukusebenza kwenhliziyo nempilo yonke yomuntu omdala ngendlela efana nokugibela ibhayisikili lendabuko noma ukushaya uhambo.
Olunye lwezifundo eziqinisekisa kakhulu lwashicilelwa kumagazini kaMeyi 2018 we-Clinical Journal of Sports Medicine, eqhathanise ukutholwa komoyampilo okuphezulu kakhulu kwabantu abadala abangama-32 abakhuluphele ngaphambi nangemuva kokuya nokubuya emsebenzini. Ubuningi (VO2 max).
I-Swiss Study Ibonisa Amabhayisikili E-Electic Athuthukisa I-VO2 Max
Ucwaningo, olunesihloko esithi "Impact of Electric Bicycles and Cycling on the Cardiopulmonary Health of Overweight Adults" ehlobo lika-2016 e-Basel-Stad, eSwitzerland kanye nohulumeni wasekhaya wase-Basel-Landschaft futhi eduze Ihhovisi liqaliswa.
Sekuyiminyaka engaphezu kweshumi uhulumeni waseSwitzerland ezama ukukhuthaza izakhamuzi ukuthi zigibele amabhayisikili endabuko noma amabhayisikili kagesi esikhundleni sokushayela noma ukuthatha izithuthi zomphakathi. Njengengxenye yohlelo, izwe libambe iphromoshini yamasonto amane "yokuhamba ngebhayisikili ukuya emsebenzini" ezinyangeni zasehlobo ezifudumele. Lokhu kuphromotha kuyinto elindelekile yocwaningo lwaseSwitzerland.
Isifundo ngasinye sasikhuluphele ngokuqhathaniswa ne-body mass index (BMI) phakathi kuka-25 no-35. (Ngokusho kwe-American Heart Association, i-BMI ibhekwa njengejwayelekile phakathi kuka-18.5 no-25.) Umhlanganyeli ngamunye ungumuntu omdala ophakathi kweminyaka engu-18 no-50. Phakathi ukungenelela, umhlanganyeli ngamunye Uzimisele ukusebenza okungenani kathathu ngesonto. Uhambo lokuya emsebenzini lwesifundo kumele okungenani lube ngamamayela angu-3.7 (amakhilomitha angu-6). Ngaphezu kokuhamba ngebhayisikili, ababambiqhaza bagcine imikhuba yokudla evamile kanye namazinga avamile okusebenza komzimba.
Ukuze banqume umthelela wokuhamba ngebhayisikili esihlokweni ngasinye, abacwaningi baseSwitzerland balinganise ukutholwa kwe-oxygen (i-VO2 max) enkulu ngaphambi nangemva kokungenelela. Isilinganiso esiphezulu se-oksijini sikala inani eliphezulu lomoya-mpilo umuntu angalisebenzisa ngesikhathi sokuzivocavoca kanzima. Kubhekwa njengesilinganiso esihle sokukhuthazela kwe-aerobic nempilo yenhliziyo nemithambo yegazi. Ngakho-ke, noma yikuphi ukuthuthukiswa ekuthathweni okuphezulu komoya-mpilo kubonisa ukuthi ukuhamba ngebhayisikili kusho impilo yenhliziyo namaphaphu.
Ekuqaleni kocwaningo, bonke ababambiqhaza abangama-32 babenezikolo ezijwayelekile ze-VO2 kanye namazinga omfutho wegazi ophumule ajwayelekile. Ekupheleni kwesikhathi sokungenelela, labo ababambiqhaza ababegibele amabhayisikili kagesi base bethuthukise i-VO2 max yabo ngo-3.6 mL/(kg·min) isuka engxenyeni engu-35.7 mL/(kg·min) ngaphambi kwecala yaba yisilinganiso esingu-39.3 mL/( kg·min) ekupheleni kwesikhathi samasonto amane. Abagibeli bamabhayisikili abavamile bajabulele ukuzuza okungu-2.2 mL/(kg·min) kusuka kwenani elingu-36.4 mL/(kg·min) ekuqaleni kocwaningo kuya kusilinganiso esingu-38.6 mL/(kg·min) esiphethweni socwaningo.
Izihloko zocwaningo ziphinde zajabulela intuthuko ekushayeni kwenhliziyo nokuphumula komfutho wegazi ngemva kwamaviki amane nje okuhamba ngebhayisikili ukuya emsebenzini.
Ngezansi, amabhayisikili kagesi "angase abe namandla okuthuthukisa ukuqina kwe-cardiorespiratory efana namabhayisikili avamile naphezu kosizo lwamandla olutholakalayo, njengoba evumela isivinini esikhulu sokuhamba ngebhayisikili kanye nokuzuza okukhulu kokuphakama," kubhala ababhali bocwaningo lwaseSwitzerland.
Amabhayisikili Kagesi Anqoba Izithiyo Zokuzivocavoca
Imiphumela yalolu cwaningo eSwitzerland ngokuyisisekelo ihambisana nemiphumela yezinye izifundo zomtholampilo. I-athikili eshicilelwe ku-International Journal of Behavioral Nutrition and Physical Activity ngo-2018 enesihloko esithi “Izinzuzo zezempilo zokuhamba ngebhayisikili elisizwa ngogesi: a Ngokusho kokuhlaziywa kokubuyekezwa okuhlelekile, izifundo eziyi-8 kweziyi-11 ezahlolwa zibonise ukuthi ukugibela ibhayisikili likagesi kungathuthukisa umoya-mpilo. ukumuncwa.
"Isilinganiso esilinganiselwe sokusetshenziswa kwe-oksijeni yokugibela ibhayisikili kagesi yi-14.7 - 29 ml / min / kg, ehlanganisa i-51% - 74% yokusetshenziswa okuphezulu kwe-oxygen," kusho ukuhlaziywa.
Okubaluleke nakakhulu, abantu abadala abaningi bangase bakuthole kulula ukuqala ukuzivocavoca ngebhayisikili likagesi kunokuhamba ngezinyawo, ukugijima noma ukugibela ibhayisikili lendabuko. Amabhayisikili kagesi angasiza abantu abadala ukuthi basebenze kakhulu.
“Abagibeli bamabhayisikili kagesi bahlinzeka ngezinga eliphezulu lokuzivivinya ngokomzimba elidingekayo ukuze lilawuleke, okubenza babe yinzuzo ngokukhethekile kubantu abafuna ukuba nempilo enhle, kodwa kungase kudingeke ukuthi kancane kancane bakhulule umsebenzi womzimba ngokucophelela, “ngokweSahluko 3” Gcwalisa umhlahlandlela womthengi wamabhayisikili kagesi. ”
Ngakho-ke, amabhayisikili kagesi angase anikeze indlela ewusizo ngokukhethekile yokuzivocavoca kulabo abahlukaniswe ngezigaba ezilandelayo: ukululama ekulimaleni okuhlobene nomsebenzi noma izifo, ukuthola ukuvivinya umzimba okuphansi, ukuvivinya umzimba kwabagibeli bamabhayisikili asebekhulile, nokubuyela emsebenzini womzimba ( Noma mathupha) ngemva kwesikhathi eside engenzi lutho,” kuphetha umqondisi wezivakashi.
