Kuphononongo olukhulu olwenziweyo ukuza kuthi ga ngoku ukuqonda ubudlelwane phakathi kokusebenza ngokomzimba kunye nokuqina komzimba, abaphandi abavela kwiBoston University School of Medicine (BUSM) baye bafumanisa ukuba ixesha elininzi elichithwe ukwenza umthambo (umsebenzi ophakathi-onamandla) kunye nokumodareyitha okuphantsi. umsebenzi wenqanaba (amanyathelo) kunye nexesha elincinci elichithwe uhleli, uguqulelwe kumzimba omkhulu wokuqina.
"Ngokuseka ubudlelwane phakathi kweendlela ezahlukeneyo zokuziqhelanisa nomzimba kunye nemilinganiselo yokufaneleka ecacileyo, sinethemba lokuba isifundo sethu siya kunika ulwazi olubalulekileyo olunokuthi ekugqibeleni lusetyenziswe ekuphuculeni ukuqina komzimba kunye nempilo yonke kwikhosi yobomi," kuchaza umbhali ohambelanayo uMatthew Nayor, MD, MPH, uprofesa oncedisayo weyeza kwi-BUSM.
Yena kunye neqela lakhe bafunde malunga nabathathi-nxaxheba be-2,000 abavela kwi-Framingham Heart Study esekelwe kuluntu abaye bafumana iimvavanyo ezibanzi ze-cardiopulmonary exercise (CPET) "kwimigangatho yegolide" yokulinganisa ukomelela komzimba.Imilinganiselo yempilo yomzimba yayinxulunyaniswa neenkcukacha zomsebenzi womzimba ezifunyenwe nge-accelerometers (isixhobo esilinganisa ukuphindaphinda kunye nokuqina kokuhamba kwabantu) ezazinxitywe iveki enye ngexesha le-CPET kwaye malunga neminyaka esibhozo ngaphambili.
Bafumene umthambo ozinikeleyo (umsebenzi womzimba onamandla ophakathi) yeyona nto isebenzayo ekuphuculeni ukomelela.Ngokukodwa, ukuzivocavoca kwakuphindwe kathathu ngokufanelekileyo kunokuhamba wedwa kwaye ngaphezu kwamaxesha e-14 ngokufanelekileyo kunokunciphisa ixesha elichithwe ukuhlala phantsi.Ukongeza, bafumanise ukuba ixesha elininzi elichithwe ukwenza umthambo kunye namanyathelo aphezulu/usuku kunokuphelisa ngokuyinxenye iziphumo ezibi zokungalali phantsi ngokokomelela komzimba.
Ngokutsho kwabaphandi, ngelixa uphando lugxininise kubudlelwane bokusebenza ngokomzimba kunye nokufaneleka ngokukodwa (kunokuba nayiphi na iziphumo ezinxulumene nempilo), ukuqina kunempembelelo enamandla kwimpilo kwaye kuhambelana nomngcipheko ophantsi wesifo senhliziyo, isifo seswekile, umhlaza kunye nomhlaza. ukufa kwangaphambi kwexesha."Ngoko ke, ukuqonda okuphuculweyo kweendlela zokuphucula ukufaneleka kuya kulindeleka ukuba kube nefuthe elibanzi ekuphuculeni impilo," watsho uNayor, i-cardiologist kwi-Boston Medical Centre.
Ezi ziphumo zivela kwi-intanethi kwi-European Heart Journal.
