Introduction: The variables of body composition and aerobic performance are decisive to evaluate the profiles of soccer players, for this reason the sports scientific community is in constant search of information on what values to discriminate to generate training strategies more in line with this type of population. The aim of this research is to compare the maximum oxygen consumption and body composition according to game position and study their relationship. Material and methods: This study has a descriptive, comparative and correlational design. The study was conducted with 26 professional female players (25.5 ± 4.0 years; body mass of 57.7 ± 5.0 kg; the height of 161.7 ± 5.7 cm) from a Chilean first division soccer club. For the evaluation of body composition, body mass (BM), standing height, perimeters, sum of six skinfolds (Ó6 skinfolds), estimated percentage of muscle mass (%MM) and percentage of body fat (%BF). For aerobic performance, VO2max was evaluated by means of this test, the following variables were determined: maximum relative oxygen consumption (VO2max ml/kg/min), maximum aerobic speed (MAS km/h), ventilatory threshold velocity 1 and 2 (VT1 and VT2 km/h), percentage of ventilatory threshold VO2 1 and 2 (% VO2 VT1 and 2), ventilatory threshold heart rate 1 and 2 (HR VT1 and 2) and maximum heart rate (HRmax). Results: The goalkeepers as the central defenders presented a significantly lower %VO2 VT2 than the lateral defenders p = 0.043 and p = 0.012 respectively. Comparisons of body coposition variables according to game position, no variable showed significant differences between game positions (p > 0.05). The simple linear regression (r2) that showed the greatest explanation between variables was VO2max (ml/kg/m) with BM (r2 = 0.220), MAS km/h (r2 = 0.480), VT1 speed (r2 = 0.412) and VT2 speed (r2 = 0.613). Conclusion: The variables MAS and Vel VT1 and VT2 seem to be elements that have a high explanation of the variance in VO2max, therefore, it is suggested to consider these elements as a guide in the planning of aerobic or continuous interval training, in order to better VO2max performance.
