Izazinzulu zangaphandle zihlalutya inani lezifundo zokufunda isiphumo esihle sokuhamba ngokukhawuleza kwaye sibaleke. Ngokusekwe kwiziphumo zayo, abaphandi bathetha ngeengenelo kunye nezinto eziluncedo omnye komnye bobabini.
Ukushwankathela iziphumo ezamkelwe kumsebenzi wesayensi, iingcali ziphawule isibonelelo esiqhelekileyo sokusebenza komzimba kwifom ye-oxygen kunye nezicubu zegazi, ukuphucula uxinzelelo kunye noxinzelelo. Kwangelo xesha, ngokutsho kwezazinzulu, kwimicimbi etyibilikayo, ukubaleka, icotha, kukwisimo esisebenzayo somsebenzi. Ke, xa umntu ebaleka, ene-70 kg, ngesantya esiyi-8 km / h, kukho ikhalori eyi-500, ngelixa ehamba nexabiso elifanayo le-5.6 km / h calorie yile itshiswe kabini encinci. Eyona nto ibaluleke nangakumbi kumzimba malunga nokwanda kobomi. Ngokweenkcukacha-mali, kuphela imizuzu emi-5 ukuya kweli-10 kuphela yokuqhuba ngesantya se-10 km / h yokunciphisa amathuba esiphumo esibulalayo sentliziyo okanye ezinye izifo eziyingozi. Izifundo zikwabonisa ukuba abantu banolutha wokuqhuba, ngokomndilili, baphila ngeminyaka engama-3.8 ukuya kwengama-14.7 ubude kunabemi beplanethi.
Kwelinye icala, ukusetyenziswa kokuqhuba njengoko eyona nto iphambili yomzimba inengxaki ecacileyo ngaphambi kokuba ihambe ngohlobo oluphezulu. Ukukhetha ukuqhuba abantu bahlala benzakala ngendlela yokuqhekeka kwe-tibia, umonakalo kwi-achille tendon okanye i-starciosis. Ngenxa yoko, malunga ne-50% ye "mbaleki" kwinkqubo yokuqhuba kwayo ziyalimala, kwaye inani lomonakalo ochaphazelekayo ukuhamba ngokukhawuleza yi-1% kuphela.
Ukushwankathela iingcebiso zayo, iingcali zicebise ngenkqubo yobomi ukuba idibanise zombini ezi ntlobo zingezantsi zomsebenzi. Kwangelo xesha, ukuze uphephe ukufumana iziphumo ezingafunekiyo, abalandeli bokuqhuba okanye ukuhamba, kungcono ukuba banxibelelane nabalulekileyo kwezonyango.
