Purpose: The purpose of the present study was to further identify the lowest effective cycling interval sprint duration and training frequency that improve VO2max. Affective and cognitive measures across different training programs were also examined to inform the feasibility and expected subjective responses to these protocols. Methods: Due to the COVID-19 Pandemic, the original methods of the study were not able to be completed. Instead, data from Towards the minimal amount of exercise for improving metabolic health: beneficial effects of reduced-exertion high-intensity interval training (Metcalfe et al., 2012) and Changes in aerobic capacity and glycemic control in response to reducedexertion high-intensity interval training (REHIT) are not different between sedentary men and women (Metcalfe et al., 2016) were obtained with the authors’ permission to assess the effect of cycling resistance on VO2max. Data Analysis: Data from the two studies were analyzed using an independent t-test to compare changes in VO2max after training against resistances of 5.0 and 7.5% of subjects body mass. Results: There was no significant difference between the percent change in VO2max following training at the two workloads (p = 0.750). Conclusion: The original research question remains unanswered; however, future research examining the physiological, metabolic, and psychological effects of the variety of training parameters involved with interval training is warranted.
