- Table 1 shows the key participant characteristics for each group, including absolute changes for weight, body fat, heart rate and blood pressure over the intervention. Data are presented as mean ± SE. PL, Placebo; dGTE, decaffeinated green tea extract; \( \dot{\mathrm{V}}{\mathrm{O}}_{2\mathrm{peak}} \), peak oxygen uptake; HR, heart rate; SBP, systolic blood pressure; DBP, diastolic blood pressure. Adenotes significant overall group x time interaction effect (P = 0.002). Bdenotes significant overall time interaction effect only (P < 0.001). *denotes significant difference (P ≤ 0.05) to baseline only within group. #denotes significant difference to week 2 within group only (P < 0.046).
