Distance covered and average power output during the performance trial. Figure 4 shows the distance covered and average power output elicited during the 40 minute performance trial for both treatment conditions at week 0, 2 and 4 of the intervention. Data are presented as mean ± SE. PL, Placebo; dGTE, decaffeinated green tea extract. Adenotes significant overall group × time interaction effect (P ≤ 0.001). Bdenotes significant overall time interaction effect (P < 0.001). 1denotes significant within group time interaction effect only (P = 0.039). *denotes significant difference (P ≤ 0.02) to baseline only within group. #denotes significant difference to week 2 within group only (P = 0.03).
