Cognitive Regulation Training and Exercise — CORTEX  

Patient Compliance Clinical Trial

Official title: Cognitive Regulation Training and Exercise (CORTEX) Trial

Status Completed

Clinical Trial Summary

The purpose of this study is to compare CORTEX (Cognitive Regulation Training and Exercise), a multi-faceted, general and exercise-specific cognitive training program plus a 4-month exercise program, to an attention-control condition involving health and wellness informational lectures plus videos. The proposed exercise program will involve both aerobic and resistive exercises. The investigators hypothesize that pre-intervention cognitive training will enhance self-regulation and self-efficacy and in turn, increase exercise adherence. The investigators also expect more positive improvements in cognitive and psychosocial function among participants in the CORTEX condition as compared to the Control condition immediately following the cognitive booster training, and across time.

Clinical Trial Description

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. ;
