Abstract: Aim: This study investigated how fatigue (measured both subjectively and objectively) and cardiopulmonary resuscitation (CPR) quality are impacted by various CPR protocols, principally comparing continuous chest compressions with intermittent rest periods. Methods: A sample of 23 participants (M = 22.3 years ± 3.8) was used in a cross-sectional design. Four compression:rest ratios were analyzed: 30:10, 50:10, 100:10, and continuous compressions (CC), with all participants performing CPR for 9 minutes in each condition. Subjective fatigue was measured using the Borg Rating of Perceived Exertion (RPE) at baseline, three, six, and nine minutes. Objective fatigue data were collected using the Parvo metabolic cart and heart rate (HR) monitors. Regression models of CPR performance quality (i.e., depth, recoil, and rate) investigated the effect of CPR protocol while controlling for participant variables. Fatigue (i.e., RPE, HR, and VO2) were compared across CPR protocols using repeated measure one-way ANOVA and post hoc Tukey’s honestly significant difference (HSD) tests. Results: Significant differences in performance were observed between CC and other protocols: 30 (p
