This is a secondary analysis from the project “CTN-0037-Stimulant Reduction Intervention Using Dosed Exercise (STRIDE)”. We aimed to test the effects of a Vigorous Intensity High Dose Exercise Augmentation (VIHD) when compared to a health education intervention (HEI) in stimulant drug-cravings and anhedonia. Three-hundred and two participants were randomized (VIHD = 152, DEI =150). No significant Time x Treatment interaction was found neither for craving nor anhedonia. For craving scores, a positive Time and negative Age effects were found. The results suggest that craving increases over time, and that younger individuals had higher craving scores across the trial. In the case of anhedonia scores, Gender had a positive direct effect, and the interaction Time x Gender had a negative effect. . Weighting the current evidence about exercise interventions for substance use, is possible that a particular patient profile and high adherence are required to be successful. Future research should focus on the identification of variables to identify who could benefit from systematic exercise programs. |
