NCT03124667

Brief Summary

The purpose of this double-blinded, randomized controlled study is to compare CORTEX (Cognitive Regulation Training and Exercise), a multi-faceted, center- and home-delivered- general and exercise-specific-active and traditional computerized cognitive training (CT) program to an attention-control condition involving health and wellness informational videos. More specifically, the cognitive training group will emphasize dual-task abilities, working memory, and visual-spatial processing, as well as self-as-exerciser priming and self-certainty training. It is hypothesized that early intervention cognitive training will enhance use of self-regulatory strategies and self-efficacy and in turn, increase exercise adherence to and engagement in a 12-month aerobic and resistive exercise program at a local fitness facility. More positive improvements in cognitive and psychosocial functioning among participants in the CORTEX condition (relative to the Video Attention-Control condition, i.e., health educational videos), are also expected immediately following the cognitive training, and across time. Expectancies and knowledge of study purpose (blinding integrity) will also be measured and used to statistically adjust for any training differences.

Outcome Measures

Primary Outcomes (1)

  • Exercise self-regulation

    Exercise self-regulation will be modeled within a latent variable framework. The change factor will be reflected by accumulated supervised and unsupervised class participation rates, total electronically-recorded visitations, averaged monthly Fitbit-derived step counts, and self-reported leisure-time exercise (via Godin Leisure-Time Questionnaire). Measures will be standardized as z-scores. The latent factor model will be adjusted for known covariates (age, gender, education level, training compliance \[percentage of completed sessions\] and injury/illness) when primary hypothesis of group effects is tested. There is always the possibility that attempts to analyze latent constructs will not converge as planned. In such a case, researchers will attempt to assess change across each behavioral outcome individually with a robust linear regression method, adjusting for multiple comparisons.

Study Arms (2)

Gaming Condition

EXPERIMENTAL

The games group will visit the lab on 5 separate occasions, for 2 hours each, to complete training sessions (playing seated and standing computerized games), and then complete 5 similar sessions at home (lasting 2 hours, but may be split into 1-hour sessions at their convenience), at the onset of the exercise program. The training sessions will be scheduled concurrently with exercise classes in the first month. This group will also be asked to accumulate 150 minutes of exercise by attending weekly supervised and unsupervised, group-based aerobic and resistance exercise classes, by visiting the fitness facility alone, and by walking or strength training at home when necessary to supplement fitness facility activities to fully meet public health recommendations, for a period of 12 months.

Behavioral: Games

Video Condition

ACTIVE COMPARATOR

The videos group will visit the lab on 5 separate occasions, for 2 hours each, to view health and educational YouTube videos, and then view 5 similar sessions at home (lasting 2 hours, but may be split into 1-hour sessions at their convenience), at the onset of the exercise program. The training sessions will be scheduled concurrently with exercise classes in the first month. This group will also be asked to accumulate 150 minutes of exercise by attending weekly supervised and unsupervised, group-based aerobic and resistance exercise classes, by visiting the fitness facility alone, and by walking or strength training at home when necessary to supplement fitness facility activities to fully meet public health recommendations, for a period of 12 months.

Will share

Upon study completion and after publication of the primary aims and hypotheses, the investigators will provide de-identified data to any interested parties with the provision that they consult with the investigators about the study design, analytical procedures, and to avoid redundancy in future planned analyses or manuscripts. The PI will be given priority and will work closely with other investigators in maximizing ways to leverage the data to address other research questions. Data generated from this project will be made available in multiple formats with codebooks via NCBI's BioProject within 12 months of completing aforementioned priorities. These include demographic information (e.g., age, gender, and education), group assignment codes, and outcome measures. No personally identifying information will be included. Users must also agree to the conditions of use governing access to the public release data.
