The study aimed to assess the relationship between peak oxygen uptake, ventilatory thresholds and maximal fat oxidation with ultra trail male female performance. 47 athletes (29 men 18 women) completed a cardiopulmonary exercise test 2 4 weeks before 107-km trail. Body composition was also analyzed using bioelectrical impedance weight scale. Exploratory correlation analyses showed that uptake (men: r=-0.63, p=0.004; women: r=-0.85, p < 0.001), speed r=-0.74, 0.001; r=-0.69, p=0.009), at first r=-0.49, p=0.035; r=-0.76, p=0.003) second r=-0.73, threshold, r=-0.53, p=0.019; r=-0.59, p=0.033) were linked race time in athletes. Percentage of mass r=0.58, p=0.010; r=0.62, p= 0.024) lean body r=-0.61, p=0.006; p=0.026) associated performance both sexes. Subsequent multiple regression revealed together able predict 66% performance; while only statistically significant variable explaining 69% variation women's time. These results, although exploratory nature, suggest is differently predicted by endurance variables women.
