Ergogenic aids Flashcards

1
Q

Compare creatine and bicarbonate as ergogenic aids to sports performance. (4 marks)

A

Creatine helps to increase stores of phosphocreatine andbicarbonate increases buffering of lactic acid
Creatine increases maximum strengthandbicarbonate increases strength endurance
Both are legal
Both are nutritional aids
Both have similar side-effects or can cause stomach cramps / diarrhoea
