Replication Data for: Psychophysiological responses to stride frequency manipulation in men and Women

Nineteen healthy adults (11 men, 8 women) completed two sessions: familiarization session (session 1) during which the preferred stride frequency (PSF1) and its corresponding speed (PWS1) were determined, and experimental session (session 2) that consisted of participants walking at four 15-minute treadmill counterbalanced conditions: the preferred stride frequency measured in Session 1 and being imposed in session 2 called PSF2, new PSF measured in Session 2 (PSF3), and ±10% deviations from PSF2.

Oxygen uptake (V̇O₂), affective valence (Feeling Scale), arousal (Felt Arousal Scale), perceived effort (RPE) and heart rate (HR) were measured. Repeated-measures ANOVA revealed significant main effects of stride frequency on V̇O₂ (p < 0.001), feeling scale (p < 0.05), and RPE (p < 0.05). Planned contrasts showed that PSF3 elicited lower V̇O₂ (p < 0.01, medium to large effect size), lower RPE (p < 0.05, medium to large effect size) and higher positive valence (p < 0.05, medium effect size) compared to the ±10% deviations.
