Values are expressed as means ± SD. Mean HR: mean heart rate, Mean SBP: mean systolic blood pressure, Mean DBP: mean diastolic blood pressure, TTE: time-to-exhaustion, Max RPE: maximal rate of perceived exertion, peak VO2: maximal oxygen uptake ‡JEE > DECAF, p < 0.05 †JEE > BASELINE, p < 0.05 | ||||
