To study body fat expenditure by the intake of amino acid drinks on the market, 10 women exercised for 40 min on a cycle ergometer. The workload was 44 % of heart rate reserve and 50 % of maximal oxygen expenditure. The subjects drank 250 mℓ of the amino acid drink (containing 1250 mg of amino acid) or the placebo before exercising. Oxygen consumption and respiratory exchange ratio (RER) were measured continuously for 50 min: 40 min during the exercise and for a 10-min rest period postexercise. Total fat expenditure calculated from oxygen consumption and RER was 1.7 ± 1.9 g (mean ± SD) for the amino acid-drink group, lower than that for the placebo group (3.9 ± 3.4 g). Sucrose contained in the drink may disturb the expenditure of fat. The results suggested that the amino acid drink did not promote fat expenditure during exercise.
