Ukubuyekezwa kocwaningo lwangaphambilini kuthole ukuthi ukuthatha i-caffeine ngaphambi kokuzivocavoca kungase kuthuthukise ukusebenza kwezinhlobonhlobo zokuzivocavoca.

Abacwaningi babhala ku-British Journal of Sports Medicine ukuthi inezakhiwo ezingathuthukisa ikakhulukazi isivinini, amandla, amandla nokukhuthazela.

UJerjek kanye nozakwabo nabo benza ukubuyekezwa okuphelele kwemiphumela yokubuyekezwa kwangaphambilini okuhlaziye izifundo eziningana ezihlobene naye nokusebenza kwezemidlalo.

Bathole ukuthi ukuyithatha kuthuthukisa ukukhuthazela kwemisipha, amandla, ukusebenza ngokugxuma, kanye nesivinini sokuzivocavoca.

"Njengomthetho ojwayelekile, ukuba nezinkomishi ezimbili zekhofi cishe imizuzu engama-60 ngaphambi kokuqala kokuzivocavoca kuba nomthelela onamandla kubantu abaningi," kwengeza uGercic.
