Peak oxygen consumption (VO2peak) testing is commonly performed to assess endurance training effectiveness in athletes, including soccer players. However, how variables such as playing position, training type (off-vs. in-season), and performance anxiety levels affect maximal exercise capacity have not been determined. PURPOSE: The aim of this study was to determine the effect of positioning, training type, and pre-performance directional anxiety on VO2 max values in female soccer players. METHODS: Sixteen female collegiate soccer players completed two trials using a cycle ergometer. VO2peak was determined by the participant’s inability to continue pedaling and/or an established plateau in VO2 despite increasing workload. Prior to testing, a Competitive State Anxiety Inventory (CSAI-2) was completed to determine somatic anxiety, cognitive anxiety, and self-confidence. RESULTS: No significant differences were found between VO2peak and positioning, training type, and pre-performance directional anxiety (p=0.085, p=0.115, p=0. 244 respectively). However, a strong correlation was found between somatic and cognitive anxiety (r2= 0.736, p=0.079). CONCLUSION: VO2peak values were not affected by positioning type in female collegiate soccer players. High and low levels of anxiety did not predict maximal performance capabilities; however, somatic and cognitive anxiety positively interacted in determining performance. To better characterize performance anxiety in the future, research could examine cortisol levels prior to maximal performance
