“In both races the participants were randomly assigned
into 1 of 2 groups. One group received a drink containing a
mixture of 3 branch chain amino acids in a 5% (cross country)
or 6% (marathon) carbohydrate solution, 5 (cross country) or
14 (marathon) times during the race. When subjects were given
branch chain amino acids during exercise, increases in tyrosine
and phenylalanine concentrations in both muscle and plasma
were prevented. These results suggest that the intake of branch
chain amino acids during exercise can prevent or decrease the
net rate of protein breakdown caused by heavy exercise.”
