PL = placebo; dGTE = decaffeinated green tea extract; dGTE+ = decaffeinated green tea extract with antioxidants. MFO = maximal fat oxidation rate; MFO·FFM−1 = relative maximal fat oxidation rate (per kg FFM); FATMAX= exercise intensity at which MFO occurs; FATMAX HR = heart rate at MFO expressed relative to maximum HR; FATMIN = exercise intensity where FATOX deemed zero. * significantly different from baseline within group (p ≤ 0.024); # significantly different to week 4 within group (p = 0.003).
