The present study aims to compare the acute and training responses of (1) eccentric high intensity interval training (EI), (2)work-matched continuous eccentric training (EC), and (3) concentric high intensity interval training (CI), all performed on cycle ergometers. The variables of interest include ratings of perceived exertion (RPE), cognitive demand (Fat), heart rate (HR), maximal oxygen consumption (VO₂max), maximal aerobic power (MAP), and various functional and health-related parameters. It is hypothesized that eccentric interval training will produce comparable or superior improvements in functional outcomes relative to concentric interval training, but at a lower metabolic and perceptual cost. Furthermore, eccentric interval training is expected to yield greater physiological benefits than continuous eccentric training for a similar perceived and metabolic load. Forty-three sedentary healthy adults (23 men and 20 women) were recruited for this study based on predefined inclusion and exclusion criteria. Participants were randomly (stratified randomization) allocated into one of three training groups. Participants attended the laboratory on 28 occasions over a 14-week period, with two sessions per week. Participants in the EI and EC groups trained using an eccentric ergometer, while the CI group trained on a concentric ergometer. Baseline and post-intervention assessments were conducted during weeks 1 and 14, respectively. These included a maximal incremental cycling test to determine VO₂ peak and concentric MAP, followed by six functional performance assessments.
