Executive functions improvement in individuals with substance use disorder: the role of high-intensity interval functional training

Objective Individuals with substance use disorder exhibit a hampered cognitive capacity due to the impairment of their executive functions. This study evaluated the effects of high-intensity functional exercises on the executive functions of individuals with such a disorder. Method Forty patients were allocated to two groups: Intervention (N = 22) and Control (N = 18). They were evaluated before and after an acute session of high-intensity functional training (Intervention group) or a period of rest (Control group). Results The Intervention group improved cognitive capacity, performance in mental flexibility, inhibitory control, working memory, and showed positive perceptual responses to effort and affection (“Clear the Mind”, “Facilitate the Walk”) compared to the Control group. Conclusion The outcome suggests that high-intensity functional exercise can be an accessible, functional, and emotionally positive therapeutic alternative for individuals with substance use disorder.
