Representation of the selected physiological variables in one single participant during the three dietary supplementations (olive oil, palm oil, and placebo). Each test was divided into three equal sections (low, moderate, and high intensity). The vertical red doted lines indicate the occurrence of aerobic and anaerobic thresholds. Note that a reduction in VE was observed at moderate intensity under olive oil supplementation. AT, aerobic threshold; AnT, anaerobic threshold
