Purpose: The purpose of this study was to examine the aerobic benefits and changes in running economy (RE) following a fourweek whole-body high-intensity interval training (HIIT) program on an athletic female population. Participants: Fourteen female student-athletes volunteered to participate in the study. Design: Participants reported on two occasions for VO2max and RE testing and were divided into two training groups based upon baseline VO2max: Endurance (END; n=6) and HIIT (n=8). Participants completed 12 total training sessions. During each session, END completed 30 minutes of vigorous-intensity running, while HIIT completed a total of four minutes of whole-body intervals. Measures: Maximal oxygen consumption (VO2max) was measured and RE was calculated during pre- and post-testing to determine whether aerobic or RE improvements had resulted from either experimental treatment. Analysis: Two two-way mixed (group x time) ANOVAs were used to compare HIIT and END pre- and post-testing changes in VO2max and RE. IBM SPSS version 22.0 was used to run the statistical tests, with an alpha level of 0.05. Conclusion: Although HIIT did not increase aerobic capacity to a greater extent than endurance training, with a significantly shorter time commitment, high-intensity interval training was an effective stimulus for improving aerobic conditioning in the female athlete participants in their nontraditional season.
