Description détaillée
Primary Aim 1: To determine the efficacy of pre-intervention cognitive training for improving exercise adherence and engagement. We hypothesize that class participation rates, physical activity counts, and self-reported exercise participation levels will be higher at 4 months for participants in the CORTEX condition relative to the Control condition. We also predict that pre-intervention training will demonstrate high feasibility/acceptability, as indicated by a thorough process evaluation.
Primary Aim 2: To determine if integrated general and exercise-specific cognitive training improves facets of executive function and exercise-related efficacy judgments. We hypothesize that participants in the CORTEX condition will show faster reaction times and greater accuracy for trained and untrained-domain-relevant tasks, including dual task performance, reasoning, and thought-stopping at post-booster testing and 4-month follow-up. Furthermore, we hypothesize that CORTEX participants will show significantly higher levels of exercise efficacy judgments, and exhibit greater automaticity (faster reaction times) in making those judgments, at post-booster testing, 1 month and 4-month follow-up.
Secondary Aim 1: We will use longitudinal mediation analyses to examine mechanisms of change brought about by the cognitive training effects on exercise adherence and engagement. We hypothesize that changes in efficacy and use of self-regulatory strategies will mediate cognitive training effects on exercise adherence over 4-months.

Expérimental: CORTEX
The CORTEX group will attend 10, 2-hour sessions for a period of four weeks prior to the initial exercise program start.
One hour will be devoted to computerized training (stationary dual-task & cognitive control training, self-priming, certainty training) whereas the other hour will be devoted to exergaming involving non-stationary, dual-task training.
