^aP < 0.05, interaction effect [breast cancer survivor (BCS) vs non-cancer control (CON)].

Independent samples t-tests and χ² tests compared characteristic differences between BCS and CON. BCS: Breast cancer survivor; CON: Non-cancer control; PRE: Pre-training; POST: Post-training; G × P: Group × phase interaction.
