This study compared the physiological responses to an acute bout of High Intensity Interval Training (HIIT) done at different pedal rates. 9 participants performed 3, 20-minute HIIT protocols consisting of a 1:1 “work:recovery” ratio on a cycle ergometer at intensities equivalent to 80% and 50% (respectively) of their PPO found from a graded exercise test. Participants’ freely chosen cadence were found then a high cadence (HC) and low cadence (LC) were then calculated to be 25% above and below that. During each HIIT session oxygen uptake (VO2), heart rate (HR), minute ventilation (V´ E), blood lactate (bLa), and rating of perceived exertion (RPE) were measured. Averages, mean peak values, and mean nadir values were calculated then analyzed using a repeated measures ANOVA (p ≤0.05). HR, VO2, and V´E were expressed as a percentage of the peak values obtained during the GXT. Results indicate a significant effect from cadence on all measures, but post hoc revealed varying results for the pairwise comparisons.
