Abstract
High-incline walking is a relatively new trend with little comparative information. This study compared physiological and psychological differences between high-incline walking at 20% grade (HIW) and level-grade jogging (LGJ) at isocaloric intensities in young adults. Twenty-two physically inactive participants (M=11, F=11) aged 18-31 years completed the study. Participants completed HIW and LGJ on a treadmill for twenty minutes on two separate occasions and matched at isocaloric intensities. Rating of perceived exertion (RPE), maintainability (HCM), and affective valence using the Feeling scale (FS) were measured at minutes 2, 10, and 20. Gas exchange and heart rate (HR) were continuously recorded. Immediately post-exercise, participants completed the Physical Activity Enjoyment Scale (PACES) and 0-100 likelihood scale. Paired-samples t-test revealed no differences in HR (LGJ=146.28±18.28; HIW=143.93±21.25; p=0.146), total calories (LGJ=169.77±35.80; HIW=171.06±35.09; p=0.504), and RER (LGJ=0.86±0.036; HIW=0.87±0.028; p=0.137). However, LGJ (96.81±15.76) had significantly higher total PACES (96.81±15.76) and Likelihood scores (75.86±18.29) than HIW (85.13±15.07, p
