Ihlabathi lezongezo liyaqhubeka ukubamba amathandabuzo amaninzi phakathi kweimbaleki. Kukho abo badla i-caffeine (kwikofu okanye kwi-supplementation) ngaphambi koqeqesho, kodwa kukho nabo bayithathayo ngexesha lokuzivocavoca ukuphucula ukusebenza. Nangona kunjalo, uphononongo lwakutsha nje iqalisa ithiyori entsha, ibalaselisa ukuba lo mkhwa unokunxulumana nokwakheka kwamahlwili egazi. Ngokusengqiqweni, oku kuya kubangela iziphumo ezibulalayo kwabanye abantu.
Icaffeine, ewe okanye hayi?
Uphononongo lubandakanya amadoda angama-48, kunye nomyinge weminyaka eyi-23 kunye nesalathisi sobunzima bomzimba. Zonke iiseshini ezimbini ezigqityiweyo, iveki enye ngaphandle, zokwandisa ngokuthe ngcembe izithuba zesantya ukuya ekudinweni (uqeqesho oluphezulu). Ngaphambili, babekhe banikwa isiselo se-placebo esingena-caffeine okanye isiselo esine-caffeine, kwaye igazi lalitsalwa phambi nasemva koqeqesho.
Bafumanisa ukuba i-caffeine yandisa kakhulu i-clotting ngexesha lokuzilolonga, ngoko ke abathathi-nxaxheba abasela iziselo ze-caffeinated banomngcipheko ophezulu wokubunjwa kwegazi. Ukugcina oku engqondweni kubaluleke kakhulu, kuba amahlwili anokubangela iingxaki ezifana ne-stroke, i-venous thrombosis, isifo sentliziyo okanye i-pulmonary embolism.
Ngaba kufuneka silahle zonke izongezo ezinecaffeine?
Mhlawumbi ndiyakuphazamisa ngolu phando, kuba awazi ukuba wenzeni ngeegels okanye iintsini ezine-caffeine. Sukuba nexhala, kuba akufuneki ukuba woyike kakhulu. Umphandi okhokelayo uPaul Nagelkirk uthi ukwanda kwe-clotting kuchaphazela abantu abanezinye izinto ezinobungozi bentliziyo, njengokutyeba, ukutshaya, uxinzelelo lwegazi oluphezulu okanye i-cholesterol ephezulu.
Olu didi lwabantu ludla ngokufumana umothuko wentliziyo ngenxa yokwanda kokungakwazi ukujiyisa.
I-caffeine ikhuselekile kubantu abaninzi, kwaye kunjalo noqeqesho. Nawuphi na umntu omdala osempilweni unokonwabela izibonelelo zecaffeine ngokuyithatha ngaphambi okanye ngexesha loqeqesho; ngoko akufanele ukhathazeke kakhulu malunga nokujika kwegazi.
Nangona kunjalo, kukho abantu abacinga ukuba "basempilweni" kwaye enyanisweni akunjalo. Kufuneka uthathele ingqalelo ukuba uyatshaya, ukuba utyebe kakhulu okanye unengxaki yobungozi bentliziyo. Kungenzeka ukuba kukho abantu abaphilileyo, kodwa banemeko ye-pathological ebeka ingozi.
Ingakanani icaffeine endinokuyithatha ngosuku?
Ngokucacileyo, isibakala sokuba akukho ngozi ibonakalayo ayithethi ukuba unokuyigqithisa. Iingcali zokufunda zincoma ukuthatha ngaphantsi kwe-400 milligrams ngosuku. Uninzi lwezongezelelo lungaphakathi kwimida ekhuselekileyo kwaye zithathwa njengezifanelekileyo kwindawo enkulu yabemi. Ingxaki ivela xa sithatha iipilisi okanye i-caffeine engumgubo, kwaye asiyihoyi imali.
Kwidosi ye-400mg sibandakanya yonke imini ye-caffeine, ngoko ke qaphela ukuba udla kangakanani ikofu. Kwakhona, ukusetyenziswa kakubi kwesi songezo akuthethi ukuba ukusebenza kwakho kuya kuphucula ngokuphawulekayo. Kuphephe ukwenza izinto eziphambeneyo kwaye ugxile kuqeqesho ngaphandle kokuxhaswa okuninzi.
