Statistical analyses
The model residuals of the appetite perceptions were shown to follow a Gaussian distribution after inspection using histograms and are presented as mean ± SD unless indicated otherwise. Time‐averaged (per hour) area under the curve (AUC) values for each rating of perceived appetite were computed using the trapezium rule for the pre‐intervention (0–70 min) and intervention (70–190 min) periods. Between‐trial differences in time‐averaged intervention AUC for appetite perceptions were analysed with a linear mixed‐effects model using the In exploratory analyses, Pearson's product moment correlation coefficients or Spearman's rank correlation coefficients were calculated to explore associations of between‐trial changes in CBF (pCASL) or BOLD signal (task‐based fMRI) with the exercise net energy expenditure and between‐trial differences in appetite perceptions. Time‐averaged (per hour) total AUC (0–190 min) for appetite perceptions was used in the correlational analysis to incorporate responses during the entire study period (baseline, pre fMRI scan, intervention period and post‐fMRI scan). Correlations for pCASL were performed after calculating a session average for CBF in the exercise and control trials, and correlations for task‐based fMRI were conducted using the BOLD signal change in the peak voxel for activated clusters in the CBF‐adjusted primary analysis (whole brain only).
