Uzothola ushoki (i-magnesium carbonate) cishe kuyo yonke indawo yokuzivocavoca. Kodwa-ke, kube nocwaningo oluncane kakhulu ngomthelela wokusebenzisa le nto ukuthuthukisa ukubamba ngenkathi uphakamisa izinsimbi. Ingakusiza kwezinye izimo futhi ikuvimbele kwezinye. Ukwazi okuhle nokubi kokuphakamisa ushoki kungakusiza unqume ukuthi uzoyisebenzisa nini ngaphandle kokuphazamiseka okuningi kokusebenza.
Izinzuzo kanye nezinzuzo zokusebenzisa kwayo
Azikho izifundo ezitholakalayo ezihlole ngokuqondile umthelela woshoki ekuphakamiseni isisindo. Nokho, izifundo eziningana zinikeze amaqiniso ahambisana nalesi sihloko.
I-athikili kaJanuwari 2018, eshicilelwe ku-International Journal of Exercise Science, ingase inikeze ubufakazi obuhle kakhulu. Laba bacwaningi bahlole umphumela we-magnesium carbonate ezifundweni eziyisishiyagalolunye ezenza ukudonsa ngezikhundla ezimbili ezihlukene zezandla. Imiphumela iveze ukuthi ukusebenzisa le mpushana ezandleni ithuthukise ukusebenza cishe ngo-16% ngokubamba okuvulekile kanye no-58% ngezandla ezivaliwe.
Esinye isihloko esivela ku-March 2015, esanyatheliswa ku-Journal of Advanced Mechanical Design, Systems and Manufacturing futhi isekela ngokungaqondile umqondo wokuthi ushoki uzosiza ukuthuthukisa ukubamba ngesikhathi sokuphakamisa isisindo. Abacwaningi bahlole izifundo ze-15 futhi babonisa ukuthi i-magnesium carbonate ukungqubuzana okwandisiwe kwesandla esifakwe iglavu ukushelela phansi kusilinda esincanyana sensimbi kufana nebha yokuphakamisa izinsimbi.
Obunye ubufakazi obusekelayo buvela kuma-gymnastics. Ababhali bombiko kaJanuwari 2014 oshicilelwe ku-Science of Gymnastics Journal bahlola ababambiqhaza abayisikhombisa futhi bathola ukuthi ukusetshenziswa kwe-magnesium carbonate kwandisa amandla ezifundo emigoqweni yokhuni yemishini yokuzivocavoca. Kuyathakazelisa ukuthi ababhali bazwakalise ukukhathazeka ngokuthi ushoki ungase ubambe kakhulu futhi ubangele amabhamuza.
Ingabe zikhona izithiyo?
Ngeshwa, ushoki kunganciphisa ukubamba kwezinye izimo. Isibonelo, umbiko kaMashi 2012 owashicilelwa kuyi-Proceedings of the Institution of Mechanical Engineers wabonisa ukuthi, kumhlanganyeli oyedwa, ushoki oyimpuphu wehlisa ukushwibeka kweminwe eshelelayo phezu kwensimbi eyomile, epholishiwe. Ababhali balolu cwaningo bakholelwa ukuthi, ngaphansi kwalezi zimo, ushoki oyimpuphu yayisebenza njenge-lubricant kunokuba insiza yokubamba.
Indatshana kaSepthemba 2016 eshicilelwe kuJournal of Applied Biomechanics yembula enye inselelo. Nakuba abantu abaningi bekholelwa ukuthi umjuluko unciphisa ukungqubuzana kwesandla, ukuba nomswakama omncane empeleni kwandisa ukungqubuzana. Ishoki inganciphisa ukubamba ngokususa umswakama omningi. Ngokusobala udinga inani elifanele lomswakamo ukuze uthole ukubamba okungcono kakhulu. Ngeshwa, ungase udinge ukushintsha izinga lokujuluka kwakho ngokusebenzisa i-sweat blocker, njenge uvaselina, ukuthola ibhalansi ephumelelayo phakathi kokunamathela nokugcoba.
Ingabe kuphephile ukusebenzisa?
I-FDA ibheka i-magnesium carbonate njengephephile, ngokombiko ka-Okthoba 2015 kuJournal of Biomaterials and Nanobiotechnology. Ababhali balolo cwaningo Abatholanga nobufakazi bobuthi. ngokusebenzisa imodeli yezilwane. Azikho izimo ezaziwayo zokungezwani komzimba, kodwa kuhlale kunethuba lokuthi ungaba ne-a ukuzwela kwamakhemikhali kushoki noma isithasiselo. Ngakho-ke sicela uhlole ngokusebenzisa inani elincane kuphela ezandleni zakho ngesikhathi sokusebenzisa kokuqala.
Kodwa-ke, uzothola izindawo zokuvivinya umzimba ezingavunyelwe ukusebenzisa i-magnesium eyimpuphu ngoba ishiya yonke into inebala kanye nenkungu ethile endaweni. Noma kunjalo, kunezinketho ezahlukene, njengoshoki uketshezi, ukugwema leyo nkinga.
