Weekly contribution of substrate to total energy expenditure (EE) for the dGTE group. Figure 2 shows the contribution of both fat and carbohydrate (based on oxidation rates) to energy expenditure during submaximal exercise for the dGTE condition. Data are presented as mean ± SE. dGTE, decaffeinated green tea extract; FAT, average fat oxidation rates; CHO, average carbohydrate oxidation rates. Adenotes significant overall group × time interaction effect compared with PL (Figure 1; P = 0.05). Bdenotes significant overall time interaction effect in conjunction with PL (Figure 1; P ≤ 0.03). 1 denotes significant interaction over time within GTE only (P ≤ 0.05).
